I am learning Android Studio and java, my level is totaly beginner but I am trying to make video player with simple buttons: Previous, Next, exit and option checkbox for random video from list.
So far it's working but just once, next clicks are just starting same video from beginning. Can someone have mercy and help me? I was looking for some codes for 3 days.
