As previously announced, as of March 15th, 2018, the Google Media Framework (GMF) for Android is deprecated in favor of the IMA ExoPlayer plugin. All development and support for GMF has been halted. If you are a GMF Android user, we recommend you migrate to the IMA ExoPlayer plugin at your earliest convenience. Alternatively, to keep using GMF Android, you will have to fork and maintain it yourself.
Note: We are NOT deprecating GMF for iOS.
If you have any questions, feel free to contact us via the IMA SDK developer forum.
