以编程方式更新apk（无root）

Question

I want to update my android application programmatically.

I used following code:

 final Intent intent = new Intent(Intent.ACTION_VIEW);
 intent.setDataAndType(Uri.fromFile(new 
       File(Environment.getExternalStorageDirectory()+"/AndroidTest.apk")), "application/vnd.android.package-archive");

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

This code display dialogue box to install application.

I want to install apk automatically.

Please help me.

Answer 1

Fortunately, this is not possible, for obvious security reasons. Apps cannot install apps without user intervention, with the exception of certain system apps that have the right permissions and such.

Answer 2

是是可以，请检查出来 。为此，您需要SUPER_USERACCESS添加此权限： <uses-permission android:name="android.permission.ACCESS_SUPERUSER" />
