I can figure out why my app has "find account on device" permission. I havent added it to the manifest file, which looks like this:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
I can read in a similair post, that it might be something about an included library, but I dont see any problems there. I am using the following libraries:
- dibs-library-1.3.0.jar
 - zbar.jar (v. 0.2)
 - armeabi.jar (needed for zbar)
 - armeabi-v7a.jar (needed for zbar)
 - x86.jar (needed for zbar)
