public class MainActivity extends Activity  implements OnClickListener

    public static final String MyPREFERENCES = "MyPre" ;//file name
       public static final String  key = "nameKey"; 
       SharedPreferences sharedpreferences ;
       Bitmap btmap;
    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         sharedpreferences =  getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
         if (sharedpreferences.contains(key))
