Deleting shared preferences

How do I delete SharedPreferences data for my application?

I'm creating an application that uses a lot of web services to sync data. For testing purposes I need to wipe out some SharedPreferences values when I restart the app.

To remove specific values: SharedPreferences.Editor.remove() followed by a commit()

To remove them all SharedPreferences.Editor.clear() followed by a commit()

If you don't care about the return value and you're using this from your application's main thread, consider using apply() instead.

我的解决方案

SharedPreferences preferences = getSharedPreferences("Mypref", 0);
preferences.edit().remove("text").commit();

Removing all preferences:

SharedPreferences settings = context.getSharedPreferences("PreferencesName", Context.MODE_PRIVATE);
settings.edit().clear().commit();

Removing single preference:

SharedPreferences settings = context.getSharedPreferences("PreferencesName", Context.MODE_PRIVATE);
settings.edit().remove("KeyName").commit();
