custom preferences
Android applications can maintain their own internal preferences (and allow them to be modified by users) with very little coding. In fact, you don't even need to write an code to explicitly save these preferences, it's all handled automatically!
Create a new Android project, with an intial activity title Main.
Create two more activities:
ShowPrefs, which extends Activity
Set Prefs, which extends PreferenceActivity
Add these two to your AndroidManifest.xml file:
