Remarks
Cancel the current device discovery process.
Because discovery is a heavyweight procedure for the Bluetooth adapter, this method should always be called before attempting to connect to a remote device with android.bluetooth.BluetoothSocket#connect(). Discovery is not managed by the Activity, but is run as a system service, so an application should always call cancel discovery even if it did not directly request a discovery, just to be sure.
If Bluetooth state is not #STATE_ON, this API will return false. After turning on Bluetooth, wait for #ACTION_STATE_CHANGED with #STATE_ON to get the updated value.
