Android - Vertical layout only

Question

How do I make sure my app is only for vertical layout?

I have tried android:screenOrientation=\"portrait\" but that doesn\'t seem to do the trick.

If you want some group of your activities to be locked on PORTRAIT mode only, than you can choose the next way:

public abstract class BasePortraitActivity extends Activity {

    @Override
    protected final void onCreate(Bundle state) {
        super.onCreate(state);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        performOnCreate(state);
    }

    protected abstract void performOnCreate(Bundle state);

}

And than just extend BasePortraitActivity where you need it. Or just add setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); to YourActivity.onCreate().
