Show menu in android on startup

Is there any way to automatically show the menu when an activity starts as it's a list activity which will be blank when it starts for the first time.

I played around with this one and it didn't matter if I put it in onCreate, onStart, onResume, onPostResume it always threw (physical Galaxy S4 @ 4.4.2 and Genymotion Galaxy S2 @ 2.3.7):

            at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2363)
            ...

The final solution that worked is:

@Override public void onAttachedToWindow() {
    super.onAttachedToWindow();
    openOptionsMenu();
}

After the activity has resumed and !isFinishing() it is safe to use openOptionsMenu in any event handler or AsyncTask.onPostExecute.

All you have to do is call either on of these in a listener and you can open or close the menu no problem.

openOptionsMenu();

closeOptionsMenu();

So call it in onCreate.

public class List extends Activity{

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout);

            openOptionsMenu();
}


// Menu Button Stuff
    public boolean onCreateOptionsMenu(Menu menu) {
        // TODO Auto-generated method stub
        super.onCreateOptionsMenu(menu);
        MenuInflater Menu = getMenuInflater();
        Menu.inflate(R.menu.menu_layout, menu);
        return true;
    }

    public boolean onOptionsItemSelected(MenuItem item) {
        // TODO Auto-generated method stub
        switch (item.getItemId()) {
        case R.id.menuBack:
            finish();
            return true;    
        }
        return false;
    }
}
