无法结束我的android应用程序

Question

I'm currently getting into android development. I try to let the user end the application by a menu button. This is my attempt:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    if (id == R.id.action_exit) {
        android.os.Process.killProcess(android.os.Process.myPid());
        super.onDestroy();
    }

    return super.onOptionsItemSelected(item);
}

The application window closes, but when I switch to the "open applications window" it is still there. How can I end/kill/close/shutdown my application completely?

Answer 1

You should think about closing your app twice, since it is not the way Android apps usually work. Instead of this you should use the code as follow:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    if (id == R.id.action_exit) {
        finish()
    }

    return super.onOptionsItemSelected(item);
}

If you really want to exit your application manually, please check out the accepted answer from the following post: How to close Android application?
