The issue is that there is a delay when I try to change the orientation of the player. There is a lag of some 2 or 3 seconds before the video resumes. Every thing else works just fine except for the orientation change.
public class MainActivity extends AppCompatActivity {
private final String STATE_RESUME_WINDOW = "resumeWindow";
private final String STATE_RESUME_POSITION = "resumePosition";

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState != null) {
mResumeWindow = savedInstanceState.getInt(STATE_RESUME_WINDOW);
mResumePosition = savedInstanceState.getLong(STATE_RESUME_POSITION);
mExoPlayerFullscreen = savedInstanceState.getBoolean(STATE_PLAYER_FULLSCREEN);
}
}
@Override
public void onSaveInstanceState(Bundle outState) {
outState.putInt(STATE_RESUME_WINDOW, mResumeWindow);
outState.putLong(STATE_RESUME_POSITION, mResumePosition);
outState.putBoolean(STATE_PLAYER_FULLSCREEN, mExoPlayerFullscreen);
super.onSaveInstanceState(outState);

You should look into handling configuration changes yourself - as @marcbaechinger mentions above.
The necessary piece is here:
<activity android:name=".MyActivity"
android:configChanges="orientation|screenSize"
android:label="@string/app_name">
The most important part is:
Remember: When you declare your activity to handle a configuration change, you are responsible for resetting any elements for which you provide alternatives. If you declare your activity to handle the orientation change and have images that should change between landscape and portrait, you must re-assign each resource to each element during onConfigurationChanged().
But if you don't have any landscape specific layout files or images, then you'll likely be okay.
We had to write our own full screen logic for rotation, but that's simple enough considering Android gives you the configuration change event.
And to tack on a little extra validity to this approach, it's recommended by Google via the Youtube player documentation (specifically in regards to fullscreen):
To achieve this for an activity that supports portrait, you need to specify that your activity handles some configuration changes on its own in your application's manifest, including orientation, keyboardHidden and screenSize.
