ContentResolverCompat.query() returned an null cursor and thus caused the NullPointerException. There are 4 main causes for this exception:

• The ContentProvider does not exist.
• The Uri which used for querying is invalid.
• The ContentProvider returns an null cursor in method query().
• A RemoteException is thrown while fetching the ContentProvider from remote process.

In this circumstance, PreferencesProvider is registed in AndroidManifest.xml and the uri is ensured to be valid. Also, PreferencesProvider does not return null in method query(). So the bug is likely to be caused by the RemoteException. Do a null-check will help.
