This app is a workaround for a bug introduced by Google at Android 4.1 (Codename: JellyBean). This bug will only affect you if you install my app from the Google Play Store and if you want to use ContactSync to sync with various address book servers.
Please also install it when you are using Android 4.4, else Android, so also this is an bug in Android, will delete your adressbooks when you update the app.
Please note that this issue also affects you if you are using a SAMSUNG device even if you have installed a more recent Android version then 4.1. So far SAMSUNG is the only known vendor which did not integrate Googles patches for this issue so that also all up to date SAMSUNG original roms are affected by this. So please install this workaround app also on current SAMSUNG devices.
If you are using Android 4.1 together with payed apps the bug mentioned above will automatically delete the user created address books during the next startup. This is NOT a bug of ContactSync itself and it affects all payed apps at the PlayStore. More details can be found here:http://code.google.com/p/android/issues/detail?id=34880
Installing this app is a workaround (to apply the workaround you have to start this app at least once) because it is a free app which will not be affected by the problem and which then will provide the necessary account details for address book creation so that you can sync to your servers with the main app ContactSync without any issues. Please ensure that the app will not the uninstalled and that the app along with ContactSync itself are installed at the internal device storage (not at the external SD card).
The purpose of this app is only to create the necessary accounts and to prevent the bug mentioned above. There is no other feature available here! You only will need this app if you are using ContactSync together with JellyBean.
In rare cases it is necessary to first install the workaround and then install ContactSync itself. (sometimes Android does not use the Workaround app if first ContactSync is installed), have you tried this?
