Learning notes Bluetooth Auto Pairing

Before doing the Bluetooth auto pairing, now tidy up a bit. Lest forget.

Home must pay attention to the problem of permissions
[HTML]View plain copy <uses-permission android:name= "Android.permission.BLUETOOTH"/>//permission to use Bluetooth <uses-permissi On android:name= "Android.permission.BLUETOOTH_ADMIN"/>//Manage Bluetooth permissions

Also note that a little simulator cannot simulate a Bluetooth device.

To automatically pair your phone's Bluetooth device with a remote Bluetooth device.
The steps are:
1. Get the phone bluetooth adapter [Java] view plain copy Bluetoothadapter adapter = Bluetoothadapter.getdefaultadapter ();

2. Check that your phone's Bluetooth device is turned on, and force the Bluetooth device on if it is not turned on

[Java] view plain copy <span style= "color: #000000;"                   >public static void Openbluetooth () {if (adapter! = NULL) {if (!adapter.isenabled ()) { Adapter.enable ();//forced to turn on Bluetooth}}}</span>

3. Get a remote Bluetooth device for a given address

[Java] view plain copy bluetoothdevice device = Adapter.getremotedevice (straddress);

4. Check if the remote Bluetooth device is paired and pair it without pairing

[Java]  View Plain  copy if (device.getbondstate ()  != bluetoothdevice.bond_bonded) {// Determine if the device under the given address is paired             try{                  clsutils.autobond ( Device.getclass (),  device, strpin);//Set pin value                   clsutils.createbond (Device.getclass (),  device);                 remoteDevice =  device;             }              catch  (exception e)  {               // TODO: handle exception            &nBsp; system.out.println ("Pairing not successful");              }    }   else {              remoteDevice = device;  }     //Auto Pairing set pin value         static public boolean autobond (Class btclass,bluetoothdevice device , String strpin)  throws Exception {             method autobondmethod = btclass.getmethod ("Setpin", New class[]{byte[].class});            Boolean result =  (Boolean) Autobondmethod.invoke (Device,new object[]{strpin.getbytes ());            return result;       }
