Only needed on Android 4.1 or Samsung devices, not required on other devices running 4.2!
The App Encryption for paid Apps introduced in Android 4.1 causes some problems for HaxSync, like the Account disappearing after a reboot.
This App is designed to work around this issue by providing an Account Authenticator for HaxSync accounts that survives a reboot as it''s a free App.
Thanks to Marten Gajda for the idea and reference implementation, check out his apps if you want more awesome sync tools!
Requires HaxSync to be installed, this is only a workaround for a Google Play issue!
