This sample demonstrates how to selectively disable Automatic Backups in Android M, either by adjusting the location where data files are stored using getNoBackupFilesDir(), or by using a custom XML configuration file. This sample can also be used as a utility to test the behavior of the Automatic Backup feature. Executing "adb shell bmgr restore com.example.android.autobackup" from a terminal will cause the sample\‘s data to be cleared and replaced with a copy from the backup server.
