Build, Install APK using Intent

Question

When I try to install an APK using:

val installIntent = Intent(Intent.ACTION_INSTALL_PACKAGE); 
    installIntent.setData(Uri.fromFile(true_path));
    startActivity(installIntent);

I receive the error:

file:///...app-debug.apk exposed beyond app through Intent.getData()

I believe that intents cannot use file:// URIs; how do I build an APK using Android Studio, such that it can be used by an intent?

Answer 1

The correct way to do it is

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