Activity finished after changing locale

Question

I have Activity A and called from it Activity B. In manifest Activity A has configChanges android:configChanges="locale|orientation|screenSize".

In Activity A - for changing locale

@Override
public void onConfigurationChanged(Configuration newConfig)
{
    super.onConfigurationChanged(newConfig);
    Resources res = this.getResources();
    res.updateConfiguration(newConfig, null);
    Intent intent = getIntent();
    intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
    intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
    startActivity(intent);
}

• for starting Activity B

  Intent intent = new Intent(this, B.class); startActivity(intent);

If I start Activity A and change locale all is working fine. But if I try to start Activity A, then start Activity B and after that go to Activity A and change locale, Activity A will not be restarted, it will be destroyed. How can I prevent Activity A from being destroyed?

Answer 1

Add the flag Intent.FLAG_ACTIVITY_REORDER_TO_FRONT to your Intent. It will reorder an existing Activity from the stack if it is already running.
