Do you have any further information in general about DRM implementation? The Android developer docs don't mention any DRM methods at all, nevertheless, when I google, I find these package and classes mentioned a lot:
android.drm.mobile1.DrmConstraintInfo android.drm.mobile1.DrmException android.drm.mobile1.DrmRawContent android.drm.mobile1.DrmRights android.drm.mobile1.DrmRightsManager But there's no information on how to make use of them. Are they not meant for public use? I also looked for third party commercial libs and found http://www.discretix.com/PDF/Discretix_DRM.pdf http://www.irdeto.com/documents/HL_CW_OMA_DRM_Android_EN_H.pdf Does anbody have experience with those on Android?
