Question

I have stored the username and the password in the sharedpreference.
And I am displaying the username in every activity like Welcome “Username”.
But at the time of logout I have put one checkbox in the dialog box.If the check box is checked the sharedpreference value should be clear. So I don’t know how to do it.Please help me out of it. Thank you.

Answer 1

The method to clear the sharedpreferences is this

http://developer.android.com/reference/android/content/SharedPreferences.Editor.html#clear()

With this you dont delete the xml

Editor.clear();

Editor.commit();
