this code in new activity, previous connected sphero spheroconnectionview :

@override

public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     final string robot_id = getintent().getstringextra(buttondriveactivity.extra_robot_id);         setcontentview(r.layout.mjoystick);     if (robot_id != null && !robot_id.equals("")) {         mrobot =(sphero) robotprovider.getdefaultprovider().findrobot(robot_id);
