title: getFloat of SharedPreferences not saving good values
body: <p>I have a little game and I need to store some score information and some data if a stage is open or closed. I tried with externalstorage, internal storage and now with shared preferences. 
  My game has only one activity and  screens. A screen has a methond called pause which is called when we change the screen and also at the end when onPause is called too.
  I put the save method in every screen but no succes.
  My class GameImpl extends Activity.
  so I called the method load and save it a GameImpl instance which is the same in every class screen that I have. The code in class Settigs.java is below with the two methods load and save:</p>

  <p>For now I believe just the score is not displaying propretly. The sound is ok, It save the state and the stages/planets are oppend and closed correctly but the score is 00.00 for all the stages that are open. I do not know why..</p>
