We are writing a full-fledged browser for Android. WebView - create your own browser. How to make your application. Android browser.

I started learning programming for Android not so long ago. After Eclips released my first Hello Word, I immediately wanted more: a lot of plans and grand ideas arose. One such idea was to write my Browser. I think many novice programmers had this desire. These are the requirements that I set and what happened in the end.

  • The program should open links global network, freely navigate through the pages forward and backward;
  • Have the ability to download files and upload back to the network;
  • Create bookmarks and save them;
  • Have the ability to download links sent from other applications;
  • There should be a home page button, a menu with various settings, etc.

In general, a full-fledged browser with your own hands. We translate this into code.

The program is written based on the standard webview included with Android. As start page I use Yandex, this is a matter of taste. The main Activity will be MainActivity.

First we set up the markup xml file -activity_main.xml. We use LinearLayout as the main container - we wrap it with a ProgressBar to display the loading process. Next, we create another LinearLayout container - we wrap our Webview and FrameLayout in it (we use it to stretch the playback video to full screen).

View code

LinearLayout xmlns: android \u003d "http://schemas.android.com/apk/res/android" xmlns: tools \u003d "http://schemas.android.com/tools" android: layout_width \u003d "match_parent" android: layout_height \u003d "match_parent" android: orientation \u003d "vertical" tools: context \u003d ". MainActivity"\u003e

Let's start writing code in MainActivity

The project can be downloaded

Good day!

It so happened that by writing a review of one browser and comparing it with the others, I wanted to write more about each of them, because each of them is good for something specific (although it would seem that it can be more definite than web surfing ☺) . One browser has an excellent friendly interface, but it takes a long time to load, another eats a lot of energy and often crashes, but it is convenient to work with a large number of tabs on it, and the third one is perfect for quickly viewing the link of interest. No need to choose. Download whatever you like. As for the synchronization of bookmarks, this is not a problem, I will describe in detail several ways how they can be saved for all browsers at the same time. And if you don’t like the interface of any of the browsers (which, considering their number, is unlikely ☺), create your own. Just create your own browser !!! This feature is provided by the browser, which I marked on the list as my favorite.

To make the program description useful, I will write in two sections:

  • program description: how to save and sort notes, speed up loading, adjust the view and the necessary functions using themes and settings, and little things that distinguish the browser from others;
  • personal experience of using: what I like about this browser and what disadvantages I discovered.

    If the former comes in handy after downloading the program to make it easier to understand the controls, then the latter will just help you decide whether to download it at all.

    Note: browsers were used on the Sony Xperia Tablet S tablet. On other devices, different speeds and characteristics are possible. But according to observations, the interface and functions remain the same.

    I have 12 browsers on my tablet. If you exclude the standard Android browser and Google Chrome, exactly ten remain:

  • UC Browser;
  • Boat Browser (standard);
  • Boat Mini;
  • Opera Mini;
  • Opera Mobile;
  • UltraLight Browser;
  • One browser
  • Firefox
  • Maxthon
  • Maxthon HD (my favorite).

    1. UC Browser

    Interface

    The appearance of the program is minimalistic and is more likely for smartphones.

    By default, it works in portrait mode. Installing themes is not supported. The maximum number of downloads is limited to 5 ... However, if you make the settings, the browser can be adapted well for other devices. The menu is quite convenient, and easy to understand!

    In this browser, pages that are often used, for example Yandex, are displayed very unusually:

    Thanks to this, the page loads in seconds.

    Tabs

    Tabs do not occupy the top of the screen; To see open pages, you need to click on the button at the bottom of the screen:

    Bookmarks

    To add a bookmark, just click on the yellow star (it seems to me that this star is the same ☺ in all browsers).

    You can choose to save any previously created folder or save to the root and then, at your leisure, sort. It is very nice that you can send a bookmark directly to the desktop.

    Pleasant trifles

    Management in landscape mode is very unusual! You probably never made such gestures. To close the current tab, you need to touch with two fingers and ... just swipe down. And to open a new tab, vice versa up.

    My opinion

    Overall a great, fast browser that's hard to compare with anything else. Despite the fact that the first impression is not always good, as I had because of the large elements. But the interface can be changed almost beyond recognition only with the help of settings. I think this browser certainly deserves attention and a little space in the memory of your device.

    2. Boat Browser Mini

    First, a general description and a small instruction manual.

    Appearance of the program

    The program interface is quite simple, but it can hardly be called intuitive. The control buttons for calling the menu are too small for touch control, although you can get used to it.

    But the screen is not cluttered and it is convenient. There are six buttons, and they are for the most popular actions: save bookmarks or go to the previous or next page.

    A more advanced menu is hidden behind the right-most button. At the first start, an empty tab appears, which can later be replaced with any site by setting it as the home page.

    Unlike most browsers, in which mobile versions the installation of themes is not supported, in the Boat browser they are: all themes are divided into installed and online themes. The first ones can be changed at least every day, they are already installed in the browser, but they do not differ in originality. If you want more beautiful solutions, themes can be downloaded from the Play store for free.

    But this is in theory. In practice, I was able to download only one topic, and then at the first start. In other cases, I just got on home page Play Market.

    Tabs

    The browser supports up to eight tabs, usually this is quite enough. Unlike Chrome, they do not occupy the top of the screen, they are accessed using a small button at the bottom. Tabs are presented as thumbnails of open web pages and are easy to scroll through.

    Bookmarks

    It's very nice that bookmarks can be sorted by pre-created folders when adding or changing an existing bookmark.

    Bookmark management is intuitive: if you drag it from left to right in the list, you can quickly select several bookmarks,

    from right to left: move them.

    Pleasant trifles

    Very interesting featurewhich is not in standard browsers: User Agent.

    It can convince the browser that you are sitting from a home computer or device with a different operating system.

    Often, mobile versions of sites are trimmed for faster loading and correct display. The default in UA is Android,

    but it can be changed with one click. Here is an example of a Google page loaded with various agents:

    Another interesting, but, in my opinion, a little useless function: night mode. It just makes the page gray-black, and some notes and pictures just disappear! But this function can be used to adjust the brightness. To switch to the normal screen, just click on the button "day mode".

    You can take a screenshot (screenshot) directly in the browser in a couple of clicks. In this case, only the program window is removed.

    Personal experience

    Speed

    Loading pages, even with a slow connection, is fast enough. On average, sites load 3-12 seconds faster than in an Android browser, and 4-6 seconds faster than in Chrome. However, for example, UltraLight Browser has much better speed, but tabs are not supported there.

    While loading several pages at the same time, for example in different tabs, I noticed a decrease in speed by about half, and sometimes even Google loaded as much as half a minute!

    Work on a slow internet

    I used the browser for both Wi-Fi and 3G. My operator has a fairly low connection speed during the day, but in these conditions the Boat Mini shows the best speed results, which is why he became my main assistant in difficult conditions ☺.

    Departures

    The browser crashes infrequently: for a month of use, it freezes only once. The touch response is always flawless, although sometimes you can just miss the button!

    disadvantages

    It is all about virtues. But, of course, not without flaws. I wrote about one of them at the very beginning: small menu buttons. However, they are located far from each other, so it is difficult to miss. But the context menu is not so easy: you can easily add a shortcut instead of saving the page.

    Another drawback is that if you press the "home" button (referring to the standard hardware button of the system), then after returning to the browser, all open pages are reloaded. Although this usually happens infrequently, but if many tabs have been opened, then this is rather unpleasant. However, if you switch between open applications without returning to the desktop, this does not happen.

    Also, it is not encouraging that bookmarks cannot be synchronized, so that leaving a bookmark on the computer (in the Windows version of the browser), you can find it on your tablet and smartphone. However, you can transfer all bookmarks from the standard Android browser in seconds. Although for people who are actively using multiple devices, this browser is unlikely to be the main one.

    3. Boat Browser

    Almost the same browser, only without the prefix "mini" in the name and with slight differences in the interface. Here are some screenshots that demonstrate this:

    Tab organizing is more like Google Chrome than Boat Mini.

    In addition to the usual tabs at the top, there is also a page manager:

    In general, the organization of pages is beyond praise: in addition to tabs and the page manager, you can control using gestures.

    Gesture management

    Draw directly on the page, although by default it will not be visible, but if the gesture is drawn correctly, you will get where you want.

    If you want, when drawing a gesture, you see it, just change it in the settings. True, then you will constantly have traces of zoom and scroll and soon disappear. There are few predefined gestures, and they are mainly for managing tabs. From sites using gestures, you can open only Google and Facebook.

    4. Maxthon

    Interface

    The first big advantage of the program: a convenient interface, which landscape orientation very different from all the browsers I've ever had to deal with. In order to leave a bookmark or see the address bar, just pull the translucent arc at the very top.

    Tabs

    To access the tabs, you need to touch the small circle in the lower corner and pull up.

    To close an open page, just drag up its thumbnail.

    Such control is very convenient when you do not want to clutter up the screen, but if, on the contrary, you want to see all the tabs as usual at the top of the page, you can change the display settings by clicking "restore", or simply turn the device.

    Pleasant trifles

    The biggest advantage of the browser is cloud cover. So say the developers. For me this is not important, but it's nice to think that all my bookmarks, and even downloads, are safe. Maxthon was the first browser to sync all devices with the cloud. Now, on the contrary, it is more difficult to find a browser without synchronization and this is now not the most important difference between the browser. Although unlike other browsers that only save bookmarks and, at best, settings, everything is synchronized in Maxthon. Even downloads are saved in the cloud, it's enough just not to uncheck the pop-up window before downloading.

    A spoon of tar

    If not for her, the browser would be perfect, but nothing is perfect ... Tar here is presented in the form of constant crashes. Well, it’s not so regular, but it still spoils all the joy, it’s especially unpleasant when you go into a previously minimized program to find out that all pages have closed, like the browser itself. It flies not only after folding, but just like that, for no apparent reason. It’s just that all open tabs disappear, leaving a page already sore quick access. But still, the overall impression of the browser is pleasant, although I did not use it to write this review ☺.

    5. Maxthon HD

    Version previous browserDesigned specifically for tablets.

    The interface is slightly different from the usual Maxthon browser, and for comparison, here are a few skins.

    Night mode:

    Adding bookmarks:

    When you first open the browser, they suggest registering or logging in under your name and choosing a user’s photo, which will always be displayed in the upper left corner. As you can see, I put my parrot ☺.

    The site is not just about the browser. If you understand English, it can be a great source of engaging articles. From there, you can go to the most popular sites, social networks, online stores and search engines.

    Both Maxthon are perfectly "friendly" with each other: they can be synchronized in the cloud, if you log into each under the same name, the bookmarks and history will be the same and the extensions downloaded for one browser will automatically appear in the other.

    In order for translucent buttons to appear, it is not enough to touch the screen: you need to make a zoom or scroll, i.e. Scroll or enlarge the page. You can quickly flip through a page using both the interface itself and the volume buttons.

    The functions and capabilities are the same as in the previous browser, so I will not repeat it. Although, of course, this browser has its own

    Pleasant trifles

    In addition to the usual tabs, pages can be displayed in the form of small thumbnails. To do this, just click on the second button below.

    The browser is very smart and great for viewing large pages. Zoom and scroll instantly and the page is live! For all the time I used it, it never crashed. Sensations are only positive!

    Unique browser in 5 minutes

    One of the most interesting suggestions from Maxthon is to create your own browser! And for this you do not even need to download a regular browser. Just go from your favorite browser to http://custom.maxthon.com/custom/.

    I advise you in advance to prepare an icon for your future browser (picture 72 by 72) and background (480 by 800).

    If you are too lazy to seriously search for pictures, and you just want to try out the function, you can choose the standard settings everywhere, and you will get a normal Maxthon browser, only with your own name. You can download the finished work of art by the link that will be sent to your mailbox. I advise you to pre-check the box next to the item that allows installing applications not from the Play store.

    6. UltraLight Browser

    Ultra-light browser, in a minimalist style, without unnecessary features. Ideal for quickly viewing links or, for example, just to find out the weather and exchange rates. You can leave bookmarks. But there is always only one tab.

    The page is completely blank, except for a small blue ... as it would be more beautiful to call it ... a small blue gizmo.

    Just need to pull it to see the address, settings button and add bookmarks.

    There is no story. In theory, this “contraption” can be not only blue, but also metal or black. But I can’t change it, I hope it gets better after the update.

    Pleasant trifles

    Speed. This, of course, is always pleasant, although it is far from a trifle. The page loading is fast enough, and, of course, I would like good surfing at that speed. Alternatively, you can roam Wikipedia by clicking on the links in the article. Although there are many separate programs for it that allow you to save the page and display articles nearby on the map (thanks to this function, I found out that I walk past sights twice a day ☺).

    In general, the browser does not claim to be the most important and beloved, but with its function "quickly view the link" copes with five plus!

    7 and 8. Opera Mini and Opera Mobile

    Many people know that Opera is the most popular mobile browser. But which one? Which is better: Mini or Mobile? For myself, I decided for a long time that they are both good, but I downloaded Opera Mobile later and became more attached to the Mini. I have it on my old phone Sony Ericsson, was the only normal browser. It seems that his OS was Symbian. Pages loaded quickly enough for GPRS, the interface is nice, good integration with the computer. Everything is better on Android! The browser is simply designed for a pleasant touch control. This is me about both versions ☺.

    What is the difference?

    Well, firstly, different application icons:

    Secondly: Opera Mobile seems more tablet-like ...

    The speed of the Opera Mini is a couple of seconds better, although this is not so noticeable, if not compared with a stopwatch in your hand ☺.

    But there is still a difference: in Opera Mini, you can immediately search the Yandex and Wikipedia services from the search bar. This adds to the benefits of the browser.

    The organization of tabs in both browsers is equally convenient, I did not notice any restrictions on their number.

    In general, both browsers can successfully claim to be the default browser, but I personally prefer the first one of the two.

    9. One browser

    Very interesting, nice browser. True, without the support of the Russian language and the sites offered for quick access are also all in English, the browser attracts with its nice icon, good speed and stability.

    But first things first.

    Interface

    Like the old UC Browser, nothing special. The address and search strings are separate, and this seems a bit old-fashioned. There are no such nice elements that you can move, pull, stretch like in Maxthon. Serious complaints to appearance No, but there are nicer interfaces.

    Bookmarks

    The organization of bookmarks is normal: you can leave your favorite page in bookmarks, add a shortcut to the quick access panel or to the desktop.

    Tabs

    To access the tabs, you must first click on the translucent button on the right and then jewelryly get to the tabs icon, which displays thumbnails of open pages. Among them, there will definitely be a quick access panel, if you, of course, did not specifically close it.

    Context menu. It is one-on-one similar to Boat browsers:

    Features

    Personally, it was interesting for me to poke around the Chinese Internet using the built-in search engine Naver ☺.

    10. Firefox

    One of the most popular browsers.

    The interface is beautiful, animated. But management is not very. For example, by pushing the list of tabs on the left (for this you need to get into the small button jewelryly), you want to close it by simply pulling it back. But it won’t work out. You need to get into the same button again. And if you want to always see your tabs - you have to come to terms with the fact that the open page will be half visible.

    Why did I start with flaws? I just wanted to quickly write about them and go on to describe the numerous advantages of the browser.

    Interface

    As I wrote, he is just great! For example, if you try to reduce the unapplied page, the program will not simply ignore your actions. The page will decrease until you release it, and again will return to its normal form. A trifle, but nice ☺.

    The speed is just wonderful, in no way compared to the standard Android browser.

    Reliability at the highest level. I have never flown. Sites can load in all tabs at the same time and even with the browser closed.

    There are such pleasant sensations from using the program that it is impossible to explain, because the general long-term opinion is made up of little things. And Firefox is one such case. (Another case of browsers is Maxthon browsers, which I simply adore ☺.)

    All bookmarks in all browsers

    So, if you followed my advice and downloaded several browsers and are actively using all (or at least most), organizing bookmarks will seem like a problem. Or you already have dozens of bookmarks in each browser, and if you want to go to your favorite site, you will have to remember which browser you left the bookmark on. For me, this was also a problem, but I found a solution. And not one. ☺

    Firstly, you can simply copy the link address and save it in any notebook. The best wayOf course, Evernote.

    The fourth way to synchronize your bookmarks is the One Hundred Bookmarks site.

    It is enough to leave a bookmark on the site itself in each browser once and save bookmarks there. In addition, you can view bookmarks of other people, and if you do not want to view yours, just make them private.

    The fifth way to save is the site http://zakladki.by and the android application for it. The program is very convenient, perfectly organizes bookmarks and there are social networking features. To leave a bookmark on the computer for a couple of clicks, just add the site to your favorites.

    Work in the program is also quite comfortable, intuitively simple minimalistic interface. And one more nice detail: it is possible to import bookmarks you have already created, though only from a computer and only through the site.

    The first is, of course, the text editor itself. I used the Kingsoft Office program.

    The only completely free multifunctional office for Android. Here are the formats you can create:

    I specially set a beige background and brown letters. But I will not describe all the functionality, otherwise I will hardly manage it until March. Until next.

    ☺). This is great, because you can see how good you are that you have done so much ☺.

    Of course, you could not help but notice (if you looked at the screenshots under the magnifying glass) of small icons on the left. This is a Floating touch program.

    She doesn't open like regular application, but remains on top of all applications. In fact, these are just stickers. Very cute stickers.

    Last: I described 10 browsers, but which one did I use myself? For example, to upload screenshots. The one you wrote about at a particular moment? Romantic, but uncomfortable. Why register on Yandex 10 times ?! Standard? No, too clumsy. And my favorite Maxthon uploads, of course, but no more than one photo per day ☺. If I used it, I would hardly have managed it before the summer holidays ... I used the Boat Browser Mini. Yes, which is probably why his review is the longest ☺. The speed is average and loads stably. Unlike UltraLight, which generally refused to embed photos ...

    I’m just crazy about downloading everything that’s bad (no, on the contrary, that’s good. Without any file hosting services ☺). And I download all the sets. Books (already 1600 on the reader), magazines (a little less), videos (well, you yourself probably know thousands of ways to download from VK and YouTube) and Internet pages (thanks to the amazing Pocket application that Google recommends. I’m probably I’ll write a whole separate review ☺). Somehow I wanted to supplement the collection of applications for saving notes, and I downloaded 20 applications for this. Yes, exactly 20.

    Then the Internet was cut off (my operator likes round numbers ☺). So this time, browsers fell under my hot (warmed up by a hot tablet) hand. But before writing a review, I tested them well. For a whole month this was my interesting activity, with which I am now saying goodbye, and I sincerely hope that my observations will be useful to you. Thank you for reading.

    Girl With A Silver Ring

    • Darling, I'm a bca student. I have to do one project in the last semester. So I decided to create a web that runs on the Android OS, but I'm completely for this application. So can anyone help me on this. I already installed everything necessary toolssuch as jdk, android sdk 3.0, eclipse. But now I have no idea where I should start developing the browser. So please help me ... I only have 2 months for this project. So is this possible in 2 months or not?

    It depends on what you mean when developing a browser ...

    Developing a browser mechanism + rendering from scratch is a lot of work, but you can easily create a browser based on Androids WebView using WebViewClient and create a new user interface by changing the way the user interacts with the browser.

    Webview has all kinds of interceptors to intercept browser interaction, so you can easily expand it. For example, you can allow the user to turn pages (e.g. google fastflip), experiment with 3D by matching the displayed web page in OpenGL space (e.g., in the sphere browser), etc.

    As a starting point, take a look at Alexander Kmetek's blog and his Mosambro project, which extends the Android browser by adding microformat support.

    It sounds like a really big project, and so you cannot just start from scratch and record it. You have to make a plan about how you want to implement all the parts, write class diagrams, etc. If you study computer science, you should have heard about this in previous semesters.

    First you have to ask yourself if this project is possible. as you can see from the comments, most people agree that you should not underestimate this task!

    I really suggest you understand the scope of this task, here source Androids browser giving you an idea of \u200b\u200bits complexity.

    Creating a basic browser could be done in a day or two for those with Android development experience, just as others said that WebView provides almost everything you need to display a web page. There are several settings for JavaScript and other functions to check, and then after marking the main text box for the URL and the go button, which is pretty much the main web browser.

    The real work comes in all advanced settings. Creating a browser that competes with the big guys may be a little difficult for one person in a couple of months, but to make something of your own that works is very possible. Give it a try!

    To create a full web browser in Android, you use WebView.

    Simple code binding:

    WebView wv \u003d (WebView) findViewById (R.id.webview1); wv \u003d (WebView) findViewById (R.id.webView1); wv.loadUrl ("http://www.apsmind.com");

    Android allows you to create your own window for browsing the web or even create your own browser clone using an element. The element itself uses the WebKit engine and has many properties and methods. We restrict ourselves to a basic example of creating an application with which we can browse pages on the Internet. IN latest versions The engine from Chromium is used, but there is not much difference in this for simple tasks.

    Create a new project Mybrowser and immediately replace the code in the markup file res / layout / activity_main.xml:

    Now open the activity file MainActivity.java and declare the component, and also initialize it - turn on JavaScript support and indicate the page to load.

    Private WebView webView; public void onCreate (Bundle savedInstanceState) (super.onCreate (savedInstanceState); setContentView (R.layout.activity_main); webView \u003d findViewById (R.id.webView); // enable JavaScript webView.getSettings (). setJavaScriptEnabled (true) ; // specify the download page webView.loadUrl ("http: // site / android");)

    Since the application will use the Internet, it is necessary to set permission to access the Internet in the manifest file.

    In the same manifest, we modify the line for the screen by deleting the title from our application (in bold):

    android: theme \u003d "@ style / Theme.AppCompat.NoActionBar">

    Launch the application. At our disposal appeared the simplest viewer of web pages, but with one drawback. If you click on any link, then the default browser will automatically start and new page will be displayed there already. More precisely, it was before. On new devices, when you start the application, the browser immediately opens.

    To solve given problem and open links in your program, you need to override the class Webviewclient and let our application handle links. Add the nested class in the code:

    Private class MyWebViewClient extends WebViewClient (@TargetApi (Build.VERSION_CODES.N) @Override public boolean shouldOverrideUrlLoading (WebView view, WebResourceRequest request) (view.loadUrl (request.getUrl (). ToString ()); return true;) // For old devices @Override public boolean shouldOverrideUrlLoading (WebView view, String url) (view.loadUrl (url); return true;))

    Then in the method onCreate () define instance Mywebviewclient. It can be located anywhere after the initialization of the object:

    WebView.setWebViewClient (new MyWebViewClient ());

    Now created in our application Webviewclient, which allows you to load any specified URL selected in into the container itself, and not launch the browser. The method is responsible for this functionality, in which we indicate the current and desired URL. Return value true says that we do not need to run third-party browser, and upload the content yourself via the link. API version 24 added an overloaded version of the method, keep this in mind.

    Re-run the program and make sure that the links are now loading in the application itself. But now there is another problem. We cannot return to the previous page. If we click on the BACK button on our device, we just close our application. To solve a new problem, we need to process the press of the BACK button. Add a new method:

    @Override public void onBackPressed () (if (webView.canGoBack ()) (webView.goBack ();) else (super.onBackPressed ();))

    We must verify that it supports navigation to the previous page. If the condition is true, then the method is called goBack ()which brings us back one page to the previous page. If there are several such pages, then we can consistently return to the very first page. In this case, the method will always return a value true. When we return to the very first page with which we started our journey on the Internet, the value will return false and the processing of pressing the BACK button will be handled by the system itself, which will close the application screen.

    Launch the application again. You have your own web browser, allowing you to follow the links and return to the previous page. Having studied the documentation, you can equip the application with other delicious goodies for your browser.

    If you need to open part of the links leading to your site in a browser, and open local links in the application, then apply the condition with different return values.

    Public class MyWebViewClient extends WebViewClient (@Override public boolean shouldOverrideUrlLoading (WebView view, String url) (if (Uri.parse (url) .getHost () .. ACTION_VIEW, Uri.parse (url)); view.getContext (). StartActivity (intent); return true;))

    A universal method that will open all local links in the application, the rest in the browser (change one line):

    Public class MyAppWebViewClient extends WebViewClient (@Override public boolean shouldOverrideUrlLoading (WebView view, String url) ( if (Uri.parse (url) .getHost (). length () \u003d\u003d 0) (return false;) Intent intent \u003d new Intent (Intent.ACTION_VIEW, Uri.parse (url)); view.getContext (). startActivity (intent); return true; )))

    Now let's complicate the example a bit so that the user has an alternative to standard browsers.

    To make it clearer, we redo the example as follows. Create two activities. On the first activity, place the button to go to the second activity, and on the second activity, place the component.

    In the manifest, we prescribe a filter for the second activity.

    The code for the button to switch to the second activity.

    Public void onClick (View view) (Intent intent \u003d new Intent ("en.alexanderklimov.Browser"); intent.setData (Uri.parse ("http: // site / android /")); startActivity (intent);)

    We created our own intention with the filter and provided the data - the address of the site.

    The second activity is to accept data:

    Package ru.alexanderklimov.testapplication; import android.net.Uri; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.webkit.WebView; import android.webkit.WebViewClient; public class SecondActivity extends AppCompatActivity (@Override protected void onCreate (Bundle savedInstanceState) (super.onCreate (savedInstanceState); setContentView (R.layout.activity_second); Uri url \u003d getIntent (). GetData (); WebView webView \u003d findViewById (R.id.webView); webView.setWebViewClient (new Callback ()); webView.loadUrl (url.toString ()); ) private class Callback extends WebViewClient (@Override public boolean shouldOverrideUrlLoading (WebView view, String url) (return (false);)))

    In the filter for the second activity, we indicated two actions.

    This means that any activity (read, applications) can trigger your activity with a mini browser in the same way. Launch any old project in the studio in a separate window or create a new one and add a button to it and write down the same code that we used to click the button.

    Launch the second application (the first application can be closed) and click on the button. You will not start the first application with the initial screen, but immediately the second activity with a mini-browser. Thus, any application can launch a browser without knowing the class name of your activity, but using only the line "en.alexanderklimov.Browser"transmitted to Intent. At the same time, your activity with the browser should have a default category and data. Let me remind you:

    You can present your string as a string constant and tell all potential users of your browser how they can launch it at home. But Android already has such a ready-made constant ACTION_VIEW, which according to the documentation help is the following:

    Public static final java.lang.String ACTION_VIEW \u003d "android.intent.action.VIEW";

    Rewrite the code for the button for the second application

    Intent (android.content.Intent.ACTION_VIEW, Uri.parse ("http: // site / android /")); startActivity (intent);

    What will happen this time? We remember that we have two actions, including and android.intent.action.VIEW. So our first application with a browser should also recognize this command when some user application uses this code. At least one such program "Browser" is on the emulator, and now our second activity from the first application has been added to it. A selection of two applications appears on the screen.

    And if you remove all alternative browsers and leave only your program, then there will be no choice. Your browser will become the main one. And if some application wants to launch a web page in this way, then your program will open.

    A small remark. If you replace the last line with this:

    StartActivity (Intent.createChooser (intent, "Meow ..."));

    Then in the program selection window instead top row "Open with" or its local translation will display your line. But this is not the main thing. If for some reason there’s not a single browser on the device, then this option the code will not cause the application to crash, unlike the original version. Therefore, use the proposed option for the sake of reliability.

    When buying a smartphone based on Android, at least one browser will be installed by default. It could be Google Chrome or some other browser developed by the manufacturer. But, if an already installed browser does not suit you, you can download any other from Play Market. If your device has several such applications, it becomes necessary to choose one of them, which will be used by default. The rest of this article will describe how this can be done.

    Android default browser

    Today, there are quite a few web browsers designed for Android devices. All of them have their advantages and disadvantages. But, despite their differences, you can set any of them by default by three different methods. Each of them will be described in detail later in the article.

    Method 1: set OS parameters

    The most popular and easiest default browser installation method is OS setup. To install the main web browser, follow these steps:

      1. Go to the settings of your smartphone from the main screen or application menu.


      1. Open item “Applications and notifications”.

      1. Scroll to the end to find a line "Additional settings". Sometimes, in the list you may not see this section, since it is hidden in the graph "Yet".

      1. Next, select the option "Default Applications".

      1. Choose a section "Browser", in order to set the default web browser. You can also set the settings for messages, phone, voice input and much more.

      1. When a window appears with a list of all installed browsers, check the box next to the one you want to set by default.


    1. You can now use a web browser. All links, instant messengers, in the future will open in the installed browser.

    This method is really very simple, besides you can install additional settings your smartphone.

    Method 2: Configure Web Browsers

    Using the settings, you can set any browser by default, except for the standard Google Chrome. You can perform this procedure by following a few simple steps. Further in the article, using the example of the mobile version of Yandex Browser and MozillaFirefox, we will describe in more detail all the steps that must be performed to install the main web browser. For other browsers, the algorithm of actions will be similar.

      1. Open mobile version browser, in the upper right or lower corner, click on the three vertical dots to open the menu.


      1. Find the Count "Settings" or "Parameters" and touch it to open.

      1. Find the item in the list "Set as default browser" and click on it. If you use Yandex Browser, you can find this section on home page in the search bar menu.

      1. Next, a tab will appear on the screen, in which you must click "Settings".

      1. You will go to the settings page "Default application". Now follow the same steps as described in 5, 6 and 7 points of the previous method.


    This option is very similar to the method described above. After performing a certain action, you will still go to the "Default Applications" section. But giving preference this method, you can configure the settings without leaving the web browser.

    Method 3: active link

    This option has the same advantages as the first method described. You can install any browser as the main one on your smartphone, if it provides such an opportunity.

    This method is relevant only when you have downloaded new browser from Market Play, or the main web browser has not been previously installed on your phone.

    1. Go to the application in which there is active link, click on it to go. If a window with a list of actions pops up, select "Open".
    2. You will see a tab in which you need to select a web browser in order to open the link. This should be the browser that you want to see as the main one on your smartphone, then mark the button "Is always".
    3. The selected link will open in the marked browser, which will be installed by default.

    Unfortunately, this method not relevant for applications such as Telegram, VKontakte and the like. You can not use it in all situations. But, if you recently installed a web browser, or if the default settings were deleted, this option will be the ideal solution for you.

    Optional Web Browser Installation for Internal Links

    Certain applications have an integrated link reading system called WebView. For these programs, GoogleChrome, or the WebView tool mentioned above, is used as the main browser. If necessary, you can change this parameter.
    Well-known web browsers do not have this feature, so you have to search among less popular browsers. You can stay with viewers different manufacturersalready installed in the proprietary shell of the Android OS. Before you begin the steps below, make sure that your smartphone has an active menu "For developers".

    To replace the WebView viewer, follow these steps:

      1. Go to settings and find the item "System"which is at the bottom of the list.

      1. Next, open the section "For developers". You can also find it in the main settings menu at the end of the list of actions.

      1. Now find the graph WebView Service and run it.

      1. If you are offered several options for services to view, select the one that suits you best by checking the checkbox area.

    1. Now all links will open in the browser you have selected.

    Link viewer, very rarely replaced. But you can use this option if your smartphone has the above described feature.

    In this article, all possible methods for installing a browser as the main one for an Android-based smartphone have been described. Depending on the situation, you can always choose the appropriate method for you.
