first:Bluetoothadapter.startdiscovery ();The StartDiscovery () method is an asynchronous method that searches for other Bluetooth devices for a duration of 12 seconds. The search process is actually done in the system service, and we can stop the search by using the Canceldiscovery () method. During the system searching for a Bluetooth device, the system may send the following three broadcasts: Action_disc
