Answer 1

public class CloseAppActivity extends AppCompatActivity
{
    public static final void closeApp(Activity activity)
    {
        Intent intent = new Intent(activity, CloseAppActivity.class);
        intent.addCategory(Intent.CATEGORY_HOME);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
                IntentCompat.FLAG_ACTIVITY_CLEAR_TASK);
        activity.startActivity(intent);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        finish();
    }
}

and in manifest:

Then you can call CloseAppActivity.closeApp(fromActivity) and application will be closed.
