OK,
I know there are are a fair number of questions similar to this, but non have given me the answer I'm looking for.
I have a custom rooted ROM (without play store). It's a android stick pc (So I don't have the system key to sign my app with, unless I've missed something in the kernel docs). I want my app to check nightly for updates from my server. If there is a new version I want it to download and install it without user interaction.
I know I can trigger the update screen with
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(new File(pathToApk));
intent.setDataAndType(uri, "application/vnd.android.package-archive");
startActivity(intent);
But as I said it's not what I want. SU and busybox are on the device. Anyone know of a way to do this?
You can access the PackageManager from the command line using pm. If su is present, you need to run
su pm install pathToApk.apk
To run it from a Java application, use ProcessBuilder.
