I am trying to create a music player in ViewPager when the user swipes, the player should play the next song. The views are updating correctly but the song is not sync with them. For example, it's playing the second song in the first fragment. I tried a lot of things but I'm not able to find where is the issue. Please anyone give me a solution. Thanks in advance.
