I wonder whether anyone has tried using NdkMediaDrm with PlayReady? If so, is there any documentation available?
The NdkMediaDrm API is designed for interacting with DRM technologies built into the Android operating system by the device's manufacturer. While there are Android devices that do include PlayReady (e.g. most Samsung devices), I lack information on whether they expose PlayReady through this API.
If you are simply looking to enable PlayReady playback on Android, you will want to use the Microsoft PlayReady Client SDK for Android.
