how to implement onRetainNonConfigurationInstance

Question

i made a media player in android it's working great but when i change the screen orientation, the activity is being restarted i know that this question was already asked on stackoverflow several times but none of the answers helped me. i think i should use: onRetainNonConfigurationInstance

    @Override 
public Object onRetainNonConfigurationInstance() { ... }

but i didn't know the correct way to implement it so if someone could give me a tutorial or an implicit example i would be grateful

I believe that onRetainNonConfigurationInstance() is deprecated. It will tell you to use Fragments instead. Here is a link to the Fragment documentation. Basically, you will put your UI and data into a custom Fragment, then use the FragmentManager to store an instance of your Fragment. Then, when the activity restarts, you can fetch your Fragment and reposition as needed.
