  private static final String PREFERENCES_CONTADORLIGA =  "ChangeThisTextWithSomethingYouPrefer";
  private static final String PREFERENCES_CONTADORLIGA_KEY = "ChangeThisTextWithSomethingYouPrefer";
  
  
  public void onCreate(Bundle savedInstanceState)
  
  
      // Restore preferences
      SharedPreferences settings = getSharedPreferences(PREFERENCES_CONTADORLIGA, Context.MODE_PRIVATE);
      contadorliga = settings.getInt(PREFERENCES_CONTADORLIGA_KEY, 0);
  
  
  
  
  protected void onDestroy() 
  
  
      super.onDestroy();
  
      // We need an Editor object to make preference changes.
      // All objects are from android.context.Context
      SharedPreferences settings = getSharedPreferences(PREFERENCES_CONTADORLIGA, Context.MODE_PRIVATE);
      SharedPreferences.Editor editor = settings.edit();
      editor.putInt(PREFERENCES_CONTADORLIGA_KEY, contadorliga);
  
      // Commit the edits!
      editor.commit();
  
  

I hope this should work for you. Good Luck!
