getRelation() method generates an error

Hi guys,

The app launches just fine when I first run it. But it crashes when I click "Edit Friends" menu item with this error "Attempt to invoke virtual method 'com.parse.ParseRelation com.parse.ParseUser.getRelation(java.lang.String)' on a null ". The code is same as the tutorial. protected void onResume() { super.onResume();

    mCurrentUser = ParseUser.getCurrentUser();
   mFriendRelation = mCurrentUser.getRelation(ParseConstants.KEY_FRIENDS_RELATION);
