Duplicate Class Found Modules Classes.jar

i am getting this error after implementing this dependency implementation 'com.google.android.exoplayer:exoplayer:2.11.7' . i was using VideoView but now i want to use ExoPlayer be

Solution 1:

You would need to exclude one of the dependencies from importing the package.

So change either

implementation ('com.google.android.exoplayer:exoplayer:2.11.7')
{ 
exclude module : 'android.support.v4.app.INotificationSideChannel'
}

or

implementation ('androidx.core:core:1.0.1')
{ exclude module : 'android.support.v4.app.INotificationSideChannel'
}
