I have the following problem. We created the Game Center application, which provides the basis for creating ad hoc wifi games and manages the records / meetings of such games.
Access to databases for records is carried out using the provider:
<provider android:name="com.identifier.gamecenterapp.contentprovider.MyGamesContentProvider" android:authorities="com.identifier.gamecenterapp.contentprovider" > </provider>
our demo game (as a link for future game developers) contains the following permissions:
<uses-permission android:name="com.identifier.gamecenterapp.contentprovider.READ_DATABASE"/> <uses-permission android:name="com.identifier.gamecenterapp.contentprovider.WRITE_DATABASE"/>
Now - whenever we try to access the provider with the game, we get the following error:

It is strange that this worked for quite some time. The error is only on Android 4.3, previous versions (for example, tested 4.1) did not have this problem.
Thank you for your understanding of how this can be resolved.
