This is using Java Reflection, which we don't expose. However, we do expose JNI
[0], which allows the same functionality with a different syntax:
IntPtr createRfcommSocket = JNIEnv.GetMethodID(
device.Class.Handle,
"createRfcommSocket",
"(I)Landroid/bluetooth/BluetoothSocket;");
IntPtr socket = JNIEnv.CallObjectMethod(
device.Handle,
createRfcommSocket,
new JValue (1));
// `socket` now holds a BluetoothSocket instance; do something with
it...
