[mono-android] Backup app data with BackupManager

[Igor Velikorossov]

Google provides data backup service (
https://developer.android.com/guide/topics/data/backup.html), which I'm
trying to take advantage of.

I followed the instructions, but I can't seem to get it working. I've done
the following:

   1. Registered for the backup service and got the key
   2.

   Updated the manifest.xml

   

   
   

   3.

   Extended BackupAgentHelper

   namespace App.Namespace{
   public class MyBackupAgentHelper : BackupAgentHelper
   {
   public override void OnCreate()
   {
   base.OnCreate();
   var fbh = new FileBackupHelper(this,
this.GetDatabasePath(Const.Database.Name).AbsolutePath);
   this.AddHelper("DATABASE", fbh);
   }
   }}

   4.

   In my database helper I initialise BackupManager and upon data change
   call this.backupManager.DataChanged();

And it doesn't seem to work as expected - when I uninstall and reinstall
the app the database I expect to be backup isn't getting restored.

I have also tried instigating backup manually (as per instructions
https://developer.android.com/guide/topics/data/backup.html#Testing) to no
avail.

Any help is appreciated. Thanks
