Solution

For android shared preferences, you can add the following code to your activity.

SharedPreferences prefs = this. getSharedPreferences ("com. example. app", Context. MODE_PRIVATE );

Read preferences as follows:

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 as follows:
Date dt = getSomeDate ();

Prefs. edit (). putLong (dateTimeKey, dt. getTime (). apply ();

The example directory in the Android SDK contains examples of retrieval and storage sharing. The location is as follows:

<Android-sdk-home>/samples/android-<platformversion>/ApiDemos directory
