MtpStorageManager keeps track of file information and send notifications for new files. MtpDatabase now uses this instead of MediaProvider for getting object information, although some operations are still reflected into MP. Since MtpStorageManager handles storage ids, remove that field from StorageVolume and VolumeInfo. Clean up a lot of the jni code for MtpDatabase. Bug: 63143623 Test: Test every MtpOperation in a variety of situations on Linux and Windows. Also use the shell to manipulate files. Verify that the cache is consistent throughout, and the operations behave as expected. Verify files created by the shell appear. Test: adb shell am instrument -w android.mtp /android.support.test.runner.AndroidJUnitRunner Change-Id: Id4ea810047b0c323399cd833047733e5daafb30a
