Comment créer par programmation une connexion A2DP ou comment émuler un téléphone Android à un A2DP évier?

J'ai deux téléphones android (Galaxy Tab de Samsung et HTC Desire). Les deux 2.2. La Galaxy Tab devrait être une A2DP évier et le Désir de la source. Mon but est d'acheminer le son de la Volonté de la Galaxie. Je viens de voir dans l'API, il est possible d'établir une connexion RFCOMM. Mais je veux établir une connexion A2DP. Mes exigences à la solution, c'est qu'aucun des téléphones devraient être enracinée.

J'ai trouvé dans le code source de la Bluetooth UUID classe. Et j'ai essayé d'ouvrir une Connexion A2DP avec l'Uuid.

C'est le code de la partie serveur:

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 côté client:

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

Je pourrais appairer les deux appareils et pourrait créer une connexion. Si je vais dans les paramètres bluetooth du Désir et de la pression longue sur la Galaxy Tab, j'ai le menu OPTIONS. Je peux voir le profil de média. Alors si essayé de vérifier la boîte de connexion pour connecter l'appareil avec les profils sélectionnés-je obtenir des journaux suivants:

Personne ne sait ce que je fais de mal?
D'une manière générale, la question est-il possible de connecter deux téléphones Android via Bluetooth et flux à partir d'un téléphone à l'autre? Avez-vous d'autres approches?
