Android Bluetooth is not supported

Question

I am learning to use Bluetooth in Android. I have given this permission in manifest file

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

and the main code lies here:

   private static final int REQUEST_ENABLE_BT = 0;
private static final int REQUEST_DISCOVERABLE_BT = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    final TextView out=(TextView)findViewById(R.id.out);
    final Button button = (Button) findViewById(R.id.button1);
    final Button button1 = (Button) findViewById(R.id.button2);
    final Button button2 = (Button) findViewById(R.id.button3);
    final BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
    if (mBluetoothAdapter == null) {
       out.append("device not supported");
    }
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            if (!mBluetoothAdapter.isEnabled()) {
                Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
                startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
            }
        }
    });
    button1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            if (!mBluetoothAdapter.isDiscovering()) {
                   Context context = getApplicationContext();
                   CharSequence text = "MAKING YOUR DEVICE DISCOVERABLE";
                   int duration = Toast.LENGTH_SHORT;
                   Toast toast = Toast.makeText(context, text, duration);
                   toast.show();
                Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
                startActivityForResult(enableBtIntent, REQUEST_DISCOVERABLE_BT);
            }
        }               
    });
    button2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {    
            mBluetoothAdapter.disable();
            Context context = getApplicationContext();
               CharSequence text = "TURNING_OFF BLUETOOTH";
               int duration = Toast.LENGTH_SHORT;
               Toast toast = Toast.makeText(context, text, duration);
               toast.show();
            }
    });
}

But it is telling me:

device not supported

on the screen and by clicking on a button makes the app force close so what is the problem with my android emulator?

You need to read this about some limitations of Emulator before using Bluetooth in your application.

device not supported is the message you get when

if (mBluetoothAdapter == null) {
       out.append("device not supported");
    }

That is because the Android emulator does not support Bluetooh. You need a physical device to check Bluetooth enabled applications.

If bluetooth is not supported, then why have a qemu -bt option for the emulator and why is there an emulation for a usb keyboard over bluetooth? Need to enable bluetooth so it appears as supported. There is likely a particular configuration required or a particular target needed beyond adding BOARD_HAVE_BLUETOOTH := true to BoardConfig.mk?

How does one configure bluetooth so it is enabled in the emulator?

bt[:hci-type] Bluetooth dongle whose type is specified in the same format as with the ‘-bt hci’ option, see allowed HCI types. If no type is given, the HCI logic corresponds to -bt hci,vlan=0. This USB device implements the USB Transport Layer of HCI. Example usage:

qemu [...OPTIONS...] -usbdevice bt:hci,vlan=3 -bt device:keyboard,vlan=3
