Android - first app onCreate null parameter

Question

I start develop app for Android. I have some code write in Eclipse and I use attached emulator. When I send porgram to my emulator I get some error.
Debugger show in line super.onCreate(savedInstanceState); // savedInstanceState = null

My code

public class PushAndroidActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {

        try
        {   
            super.onCreate(savedInstanceState);

            checkNotNull(SENDER_ID, "SENDER_ID");

Answer 1

Could you just try rotating your device - left ctrl F11. you will realize that the bundle is != null

onSaveInstanceState() will be called by default for a view if it has an id. The default implementation takes care of most of the UI per-instance state for you by calling onSaveInstanceState() on each view in the hierarchy that has an id. You could check these :

savedInstanceState is always null

When are ALL the cases when the onSaveInstanceState() method called?
