Oculus Quest trigger APK Installer

I'm working on an Oculus Quest app and wanted to add the option to auto update the Android app.
So far I'm able to download an apk file and call some android java code to force starting the package installer, but with no success.

Code (Java):

1. Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
2. intent.setDataAndType(fileUri, "application/vnd.android.package-archive");
3. intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
4. intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
5. intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
6. context.startActivity(intent);

The screen becomes black and showing 3 loading dots, but nothing happens and the app won't update. It works on an android smartphone, but not on the Oculus. Android 10 is installed. Does anyone has an idea why it is not working and how I'm able to install my downloaded apk file by opening the default android package installer?

 

Okay, I found some kind of solution.
Since for some reason the Oculus is not able to display a user dialog to commit the installation of an APK file, I ended up to make my app a Device Owner app. With the Device Owner privilege I'm able to install the APK file silently without some kind of user interaction.

 

Hi, how did you make your app a Device Owner?

 

Any tips on how you managed to do this? I have seen apps like Sidequest doing this on the device without any weird adb commands
