Android calls the system default browser access method _android

First, start the Android default browser

In this way, Android can invoke the default browser access to the phone.

Second, specify the appropriate browser access

1, the designated Android browser with access

("Com.android.browser": PackageName; "com.android.browser.BrowserActivity": initiating main activity)
Intent intent= New Intent ();
Intent.setaction ("Android.intent.action.VIEW");
Uri Content_url = Uri.parse ("");
Intent.setdata (Content_url);
Intent.setclassname ("Com.android.browser", "com.android.browser.BrowserActivity");
StartActivity (Intent);

2, start other browsers (of course, the browser must be installed on the machine)

You can invoke other browsers as long as you modify the following corresponding PackageName and master startup activity

Intent.setclassname ("Com.android.browser", "com.android.browser.BrowserActivity");

UC Browser ":" "Com.uc.browser", "Com.uc.browser.ActivityUpdate"

Opera: "Com.opera.mini.android", "Com.opera.mini.android.Browser"

QQ Browser: "COM.TENCENT.MTT", "com.tencent.mtt.MainActivity"

Open a local HTML file

When you open a local HTML file, be sure to specify a browser, but not the way to browse, the specific example code is as follows

Intent intent= new Intent ();
Intent.setaction ("Android.intent.action.VIEW");
Uri Content_url = Uri.parse ("content://com.android.htmlfileprovider/sdcard/help.html");
Intent.setdata (Content_url);
Intent.setclassname ("Com.android.browser", "com.android.browser.BrowserActivity");
StartActivity (Intent);

The key point is to call the "content" this filter.

Previously have in Win32 programming friend, may feel in this form "file://sccard/help.html" is OK, can be very certain to say to you, the default browser setting is not to "file" this to parse, If you want your default Android browser to have this feature, you need to modify the Manifest.xml file yourself to the Android source code, and then compile your own browser codes to generate the appropriate APK packages to reinstall them on the machine.

The overall steps are as follows:

1, open the Packages/apps/browser/androidmanifest.xml file to add to the corresponding <intent-filter> back on it

<intent-filter>
<action android:name= "Android.intent.action.VIEW"/>
<category android: Name= "Android.intent.category.DEFAULT"/>
<category android:name= "Android.intent.category.BROWSABLE"/ >
<data android:scheme= "file"/>
</intent-filter>

2, recompile packaging, installation, this way, the new browser will support the "file" the form of

Interested can go to try.
