[REQUIRED] Version of ExoPlayer being used

2.12.0

[REQUIRED] Device(s) and version(s) of Android being used

API 21 and above [physical devices + emulators]

[tonihei]

This is most likely a duplicate of #8017 and should be fixed on the dev branch.

[nishantkp]

@tonihei do you have an ETA for the next release?

[ojw28]

This will be picked up in a minor release (2.12.1), for which you shouldn't have to wait too long (probably the end of this month).

thanks @ojw28
