Android SDK 23 introduced a new way to handle permissions, so as a temporary workaround you can set it to build for SDK below 23. As a permanent solution you have to ask user during runtime for permissions with checkSelfPermission() or requestPermissions()


You need the permission android.permission.READ_EXTERNAL_STORAGE. Write on the Android Manifest


MANAGE_USERS has a protection level of signature|system, so your application must be signed with the platform key. Take a look on this for more information about it.
