How to create an A2DP connection programmatically or how can I emulate an Android phone as an A2DP shell?

I have two Android phones (Samsung Galaxy Tab and HTC Desire). Both 2.2. Galaxy Tab should be A2DP shell and source desire. My goal is to lay the sound of Desire in the Galaxy. I just saw in the API that you can establish an RFCOMM connection. But I want to establish an A2DP connection. My decision requirements are that none of the phones should be introduced.

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

This is the server side code:

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();
    }

Client Side Code:

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