/** Called when the activity is first created. */
private Cursor imagecursor, actualimagecursor;
private int image_column_index, actual_image_column_index;
GridView imagegrid;
private int count;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
File nfile=new File(Environment.getExternalStorageDirectory()+"/picture");
nfile.mkdir();
init_phone_image_grid();
}
