How to detect wither the user has clicked OK or CANCEL on Intent.ACTION_DELETE?

Question

I'm trying to make an uninstaller app and this is the part that I use to uninstall an app:

 Uri uri = Uri.fromParts("package", app.getPackageName(), null);
 Intent intent = new Intent(Intent.ACTION_DELETE, uri);
 startActivity(intent);

When the user clicks the uninstall button, a confirmation popup dialog appear. Is there a way to check if the user has clicked OK or CANCEL in the dialog box ?

Never mind guys, I finally found the solution: instead of ACTION_DELETE, I used ACTION_UNINSTALL_PACKAGE (minimum API 14) and this is the final code:

private void uninstallApps(List<AppModel> apps) {
    for (AppModel app : apps) {
        Uri uri = Uri.fromParts("package", app.getPackageName(), null);
        Intent intent = new Intent(Intent.ACTION_UNINSTALL_PACKAGE, uri);
        // store result
        intent.putExtra(Intent.EXTRA_RETURN_RESULT, true);
        startActivityForResult(intent, 1);
    }
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    // get result
    if(resultCode == RESULT_OK){
        Log.d(TAG, "onActivityResult: OK");
    }else if (resultCode == RESULT_CANCELED){
        Log.d(TAG, "onActivityResult: CANCEL");
    }
}

I hope this will help someone.

Not directly, as ACTION_DELETE is not documented to return anything.

When your activity returns to the foreground, though, you could use PackageManager and see if the app is still there.
