Finish application from parent class

Have some problem with android finish() methods. I have one parent-class activity. Lets call it ParentActivity. All other activities in my project extends ParentActivity. Each time on ParentActivity.onCreate there are some statement, and I want to stop activity from executing if it fails. But when I call finish() in parent, I cant stop executing onCreate method on its child. Something like that:

public class ParentActivity extends Activity {
     @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (!someStatement) finish();
}

public class Test extends ParentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);        
    Log.d("TAG", "I dont want this code!");
}

}

Surely, I can just verify in parent activity its status each time, but I dont think its a good idea.

public class Test extends RexActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (isFinishing()) return; /// It works - but it bad :(((
    Log.d("TAG", "I dont want this code!");
}

}

Can I somehow stop executing onCreate method on child activity from its parent? Many thanks for any help!

I'm not sure if I got your question right. As you have some grammatical issues.

  1. The onCreate statements are always executed. You can either have a Boolean in ParentActivity to stop the code from executing in ChildActivity#onCreate().
  2. You can try making your onCreate() code more modular by dividing it into functions so that it's not called.

Let me know what works for you.

Best option is to Use finish() in your splash screen just before you create your second activity,
