The report identifies PictureSelector 3.11.1 and says the demo reproduces the request, but it names no source file, test, or entry point. Begin by tracing Android media selection and playback support, then verify the requested FLV, WMV, and MPEG formats in the demo; the result should establish whether those formats are supported.
