How to create programmatically an A2DP connection or how can I emulate an Android phone to be an A2DP sink?

I have two android phones (Samsung Galaxy Tab and HTC Desire). Both 2.2. The Galaxy Tab should be an A2DP sink and the Desire the source. My aim is to route the sound of the Desire to the Galaxy. I just saw in the API that it is possible to establish a RFCOMM connection. But I want to establish an A2DP connection. My requirements to the solution is that none of the phones should be rooted.

I found in the source code the Bluetooth UUID class. And I tried to open a A2DP Connection with the UUIDs.

This is the code of the server side:

private class AcceptThread extends Thread {
  public AcceptThread() {
       try {
       BluetoothServerSocket mmServerSocket = btAdapter.listenUsingRfcommWithServiceRecord("Audio Sink", UUID.fromString("0000110B-0000-1000-8000-00805F9B34FB")); // UUID of Audio sink
       mmServerSocket = btAdapter.listenUsingRfcommWithServiceRecord(
    "AVCRP Controller", UUID.fromString("0000110E-0000-1000-8000-00805F9B34FB")); // UUID of AVCRP Controller                

    } catch (IOException e) {
    }
}

   public void run() {
// Keep listening until exception occurs or a socket is returned
while (true) {
try {
         socket = mmServerSocket.accept();

} catch (IOException e) {
    break;
}
// If a connection was accepted
if (socket != null) {
    try {
    mmServerSocket.close();
} catch (IOException e) {
    e.printStackTrace();
    }

Code of the client side:

Method m = device.getClass().getMethod("createRfcommSocket", new Class[] { int.class });
tmp = (BluetoothSocket) m.invoke(device, Integer.valueOf(1));

I could pair both devices and could create a connection. If I go to the bluetooth settings of the Desire and long press on the Galaxy Tab, I have the menu OPTIONS. I can see the media profile. Then if tried to check the connection box to connect the device with the selected profiles I get following log:

Does anyone know what I am doing wrong? A general question is it possible to connect two Android phones via Bluetooth and stream from one phone to the other? Do you have any alternative approaches?

Thanks
