If you have used SharePreference's MULTI_PROCESS_MODE, you may know that it's not reliable.

See the documentation of the SharedPreferences you might have seen one of these warnings:

Note: currently this class does not support use across multiple processes. This will be added later.

Google even deprecated the multiprocess support because it never worked relieable

DPreference is a way solving this problem powered by a ContentProvider. It works in multiple processed mode safely. You can declare your provider in a remote process, if you don't declare it in AndroidManifest.xml, it is operating in main process by default.

####Features

• works multiprocess safely
• the same api like SharePreference
• compat old app versions, don't need to upgrade. DPreference is just a wrapper of original sharepreference with contentprovider.

####Usage

       DPreference dPreference = new DPreference(context, "default");
       dPreference.setPrefString( "key", "value");

####Compare With Tray(https://github.com/grandcentrix/tray/)

• DPreference setString called 1000 times cost : 375 ms getString called 1000 times cost : 186 ms
• Tray setString called 1000 times cost : 13699 ms getString called 1000 times cost : 3496 ms

####So DPreference has a better performance.
