Question

We are saving the following from one application:

final CheckBoxPreference mCheckPref = new CheckBoxPreference(sContext);
mCheckPref.setKey("alertnotification");

and we are retrieving it from a second application follows:

mContext = context.createPackageContext("com.android.abc",Context.CONTEXT_INCLUDE_CODE |     Context.CONTEXT_IGNORE_SECURITY);
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(mContext);
boolean alertnotification = prefs.getBoolean("alertnotification",true);

I always get the alertnotification as false, even during the first time where I have set the default value to be true. Why does this happen?
