Android BackupManager and my app db: best approaches

Question

I'd like to use the BackupManager to back a DB for my app. The documentation talks about BackupAgent and BackupAgentHelper, and it states that you want to use BackupAgent if you have a DB.

On the other hand, the BackupAgentHelper has a neat FileBackupHelper that makes things quite easy.

My questions:

1) Is it possible to use FileBackupHelper to backup the .sqlite file in /data/data/<myapp>/databases?

2) if not, is it possible to use the SQLiteOpenHelper's methods inside onBackup() and onRestore() (onCreate/onUpgrade to backup/restore)?

It is possible. When you extend BackupAgentHelper and implement its onCreate(), you can do something like this in there:

addHelper(STATS_BACKUP_KEY, new DbBackupHelper(this, "my_db_name"));

And your DbBackupHelper class can look like this:

public class DbBackupHelper extends FileBackupHelper {

    public DbBackupHelper(Context ctx, String dbName) {
        super(ctx, "../databases/" + dbName);
    }
}

For a full example, check out the Andlytics project on GitHub: AndlyticsProject.
