Sharedpreferences completed

Processing methods

For Android shared preferences, you can add the following code to your activity to complete

Sharedpreferences prefs = this.getsharedpreferences ("Com.example.app", context.mode_private);

Read the preferences in the following way:

String Datetimekey = "Com.example.app.datetime";

Use a default value using new Date ()
Long L = Prefs.getlong (Datetimekey, New Date (). GetTime ());

Edit and save preferences with the following
Date dt = Getsomedate ();

Prefs.edit (). Putlong (Datetimekey, Dt.gettime ()). apply ();

The sample directory in the Android SDK contains examples of retrieval and storage sharing in the following locations
