Android Bluetooth - source code

I have been strugling with a Bluetooth project on Android fo开发者_Go百科r weeks. Does anyone know where I can go to see the actual code that's used by Google to make their Bluetooth pairing and connection logic work?

I have been through all the documentaiton, the BluetoothChat application (which doesn't work as advertised ... tried it on 3 different handsets), as well as a bunch of other sites on the net, but still no luck. I need to get an app up and running on 2.1 or higher.

Any advice or help is greatly appreciated.

Yes the Bluetooth project didn't work for me also because the code for socket connection is not working

 // Get a BluetoothSocket for a connection with the
            // given BluetoothDevice
            try {
                if (secure) {
                    tmp = device.createRfcommSocketToServiceRecord(
                            MY_UUID_SECURE);
                } else {
                    tmp = device.createInsecureRfcommSocketToServiceRecord(
                            MY_UUID_INSECURE);
                }
            } catch (IOException e) {
                Log.e(TAG, "Socket Type: " + mSocketType + "create() failed", e);
            }

this is not working ...

replace this by the following code

BluetoothDevice hxm = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(device.getAddress());
Method m;
m = hxm.getClass().getMethod("createRfcommSocket", new Class[]{int.class});
socket = (BluetoothSocket)m.invoke(hxm, Integer.valueOf(1));

Ah, if you're having issues with application level code I'm not sure staring at the Bluetooth manager source will be much help, but here you go: https://android.googlesource.com/platform/packages/apps/Bluetooth the Bluetooth manager app code.

I'll re-iterate it: this is honestly probably not going to be helpful for what you want. You should be able to get a reasonably working Bluetooth app without having to look at this.

EDIT: if you want the code that implements the Bluetooth packages (android.bluetooth), see https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth for that.

You can browse all the android.bluetooth package around here:
