This is just a workaround app for a bug in Android 4.1 (alias Jelly Bean). See
http://code.google.com/p/android/issues/detail?id=34880 for details.
Info for Samsung users: at present you'll need this app too, see ...Visualizza di più
The bug causes accounts of paid apps to be removed when Android boots up. To work around this issue this app pretends to provide the same account type that SmoothSync for Cloud Calendar provides. That's enough to convince Jelly Bean to keep the account. That's all this app does.
Please open the app at lease once from within Google Play to "enable" the workaround. It may not work properly otherwise. On some devices you'll have to install this app before you install SmoothSync for Cloud Calendar. Please try that if you still have problems.
Please note that the bug is in Android 4.1, not in SmoothSync for Cloud Calendar!
If you're not using SmoothSync for Cloud Calendar on Jelly Bean, you don't need this app. There is no need to give it a bad rating in that case! Please don't install it in that case.
