This is just a workaround app for a bugs in Android 4.1 (alias Jelly Bean) and higher which causes FocusGTD accounts to be removed during app upgrade and phone reboot.
The details to these bugs are listed here:
Info for Samsung users: at present you'll need this app too, see http://developer.samsung.com/forum/board/thread/view.do?boardName=GeneralB&messageId=232748
The bug causes accounts of paid apps to be removed when Android boots up (or when you upgrade the currently installed version). To work around this issue this app pretends to provide the same account type that FocusGTD provides. This is enough to convince Android to keep the account.
This is all this app does.
On some devices you'll have to install this app before you install FocusGTD. Please try that if you still have problems.
Please note that the bug is in Android 4.1 and higher, not in FocusGTD!
If you're not using FocusGTD on the mentioned android versions, 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.
Thanks a lot to Marten Gajda who initially conceived this workaround and shared the details on how to avoid this.
