Why not put the String into SharedPreferences using the Editor in the onPause() method of the Activity (make one if its not there) and then get it in the onCreate() method. This way you will always have the most recent version. Right now you set it to mListContent every time which is static and doesn't change.
Have that be the default one, and instead get your last one from shared preferences. I assume your new order is in mNewPositions.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
