In this video player part 14 I am going to implement lock the controls and then unlock all controls select audio track and rotate the videoview
So let's start

2.Also add the code in your AndroidManifest.xml
<activity android:name=".activity.VideoPlayer"
android:configChanges="orientation|screenSize|screenLayout|smallestScreenSize"
android:resizeableActivity="true"
android:supportsPictureInPicture="true"></activity>
