Introduction Anybody can write code. Making it work is easy, but doing it the right way requires more work, than just making it work. In my definition, the following are the characteristics of good code. But considering the long term ROI Return on Investmentefficiency and performance comes below reliability and maintainability.
A convenient BackupAgent wrapper class that automatically manages heterogeneous data sets within the backup data, each identified by a unique key prefix. An application that wishes to participate in the backup and restore mechanism will declare a subclass of BackupAgentimplement the onBackup and onRestore methods, and provide the name of its backup agent class in its AndroidManifest.
Basic Operation When the application makes changes to data that it wishes to keep backed up, it should call the BackupManager.
This notifies the Android Backup Manager that the application needs an opportunity to update its backup image. The Backup Manager, in turn, schedules a backup pass to be performed at an opportune time.
Restore operations are typically performed only when applications are first installed on a device. At that time, the operating system checks to see whether there is a previously-saved data set available for the application being installed, and if so, begins an immediate restore pass to deliver the backup data as part of the installation process.
This prepares the agent instance to run the actual backup or restore logic. A backup data set consists of one or more "entities," flattened binary data records that are each identified with a key string unique within the data set.
Adding a record to the active data set or updating an existing record is done by simply writing new entity data under the desired key. Deleting an entity from the data set is done by writing an entity under that key with header specifying a negative data size, and no actual entity data. Helper Classes An extensible agent based on convenient helper classes is available in BackupAgentHelper.

Class Overview. Provides the central interface between an application and Android's data backup infrastructure. An application that wishes to participate in the backup and restore mechanism will declare a subclass of BackupAgent, implement the onBackup() and onRestore() methods, and provide the name of its backup agent class in its plombier-nemours.com file via the tag's android.
