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 msgetString
called 1000 times cost : 186 ms - Tray
setString
called 1000 times cost : 13699 msgetString
called 1000 times cost : 3496 ms
####So DPreference has a better performance.
