startActivity in onCreate()

Question

I need to start Activity in onCreate of another Activity and wait until activity2 finish. How to do that?

public class Activity1 extends Activity{
    protected void onCreate(Bundle bundle) {
        super.onCreate(bundle);
        //do some code
        startActivity(Activity2)
        //wait until activity2 finish
        //another code which can be done after activity2 finish
    }
 ...
 }

Or I need to do another code in OnActivityResult async way??

Answer 1

You should try this way...

public class FirstActivity extends Activity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent i = new Intent(SecondActivity.this, getApplicationContext());

        int requestCode = 0;
        startActivityForResult(i,requestCode);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

       // do your stuff here after SecondActivity finished.
    }
}

Hope this helps you.
