d21eac9c70
Uses a new "MTP objects" table in the media provider to support basic enumeration of the external storage file system. Support for accessing audio, video and image metadata in the existing media provider tables will be added in a later commit. The C++ MtpDatabase class is now abstract, to support a proxy subclass that calls through JNI to the Java MtpDatabase class in the media provider.
