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
<application android:backupAgent="app.namespace.MyBackupAgentHelper"
android:restoreAnyVersion="true">
<!-- backup service registration -->
<meta-data android:name="com.google.android.backup.api_key"
android:value="xxxxxxxxxxxxxxxxxxxxxx" />
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
