Ima html5 sdk custom playback changes

On September 16th, 2015 , the IMA HTML5 SDK will change how it handles custom playback. In order to provide a more seamless ad experience, custom playback on Android 4.0+ devices will be disabled . As per a previous change , the SDK only selects custom playback when necessary. Since Android 4.0+ devices support standard rendering , it is no longer necessary to use custom playback on these devices. What must I do to prepare for this change?...
