无提示安装Apk（root用户访问权限）

Question

I am creating an app for Android Tv 's in which Apk downloads its updates and intsalling but i tried both of the cases

   String command;
        command = "adb install -r " + filename;
        Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command });
        proc.waitFor();

And this too:

Intent intent = new Intent(Intent.ACTION_VIEW);
          intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
                startActivity(intent);

On first case file downloaded successfully and installing in background after done it will run commands successfully and restart using receiver but its not updating app it shows old version !!

On second case it ask from user Install Or Cancel , Sometimes (users did'nt find mouse or remote) for tv so I don't want to show this prompt too. !! Can Someone please recommends me the better option which install without any clicks it may background or foreground not matter . Please Help !! Thanks

Answer 1

You need to be rooted, but here's some code I used on 6.0 to do this. I have not tested it on previous or newer versions, and its using Android private APIs so it may die at any time. Also, the app will be force closed if it updates itself, so you're best off running this in a second app so it can restart your activity when its updated.

I believe the permission you need is <uses-permission android:name="android.permission.INSTALL_PACKAGES" /> but its hard to tell since this was a kiosk mode app that installed dozens of permissions because it was impossible to update the list properly.
