java.io.IOException: accept: La conexión no se crea (falla o se anula)

Quiero crear BluetoothServerSocket en Samsung GALAXY TAB 8.9. (android 4.04) Cuando invoca mmServerSocket.accept () – lanzado:

"java.io.IOException: [JSR82] accept: La conexión no se crea (falla o aborta)."

He leído muchos artículos similares, pero no han detal respuesta. Tal vez alguien resuelto problema similar o saber lo que significa esta Excepción.

Gracias.

Código obtenido del ejemplo android "ChatExample":

public class AcceptThread extends Thread { // The local server socket private final BluetoothServerSocket mmServerSocket; private String mSocketType; public AcceptThread(boolean secure) { BluetoothServerSocket tmp = null; mSocketType = secure ? "Secure" : "Insecure"; try { tmp = mAdapter.listenUsingInsecureRfcommWithServiceRecord( NAME_INSECURE, MY_UUID_INSECURE); } catch (IOException e) { Log.e(TAG, "Socket Type: " + mSocketType + "listen() failed", e); } mmServerSocket = tmp; } public void run() { if (D) Log.d(TAG, "Socket Type: " + mSocketType + "BEGIN mAcceptThread" + this); setName("AcceptThread" + mSocketType); BluetoothSocket socket = null; // Listen to the server socket if we're not connected while (mState != STATE_CONNECTED) { try { // This is a blocking call and will only return on a // successful connection or an exception Log.d(TAG, "Socket " + socket + " | ServerSocket " + mmServerSocket); socket = mmServerSocket.accept(); Log.d(TAG, "new accepted Socket with " + socket.getRemoteDevice().getName()); } catch (IOException e) { Log.e(TAG, "Socket Type: " + mSocketType + "accept() failed", e); // BluetoothServiceViaProtobuf.this.start(); break; } // If a connection was accepted if (socket != null) { synchronized (BluetoothServiceViaProtobuf.this) { switch (mState) { case STATE_LISTENING: case STATE_CONNECTING: // Situation normal. Start the connected thread. connected(socket, socket.getRemoteDevice(), mSocketType); break; case STATE_NONE: case STATE_CONNECTED: // Either not ready or already connected. Terminate new socket. try { socket.close(); } catch (IOException e) { Log.e(TAG, "Could not close unwanted socket", e); } break; } } } } if (D) Log.i(TAG, "END mAcceptThread, socket Type: " + mSocketType + " "+ BluetoothServiceViaProtobuf.this.getState()); } public void cancel() { if (D) Log.d(TAG, "Socket Type" + mSocketType + "stop " + this ); try { mmServerSocket.close(); } catch (IOException e) { Log.e(TAG, "Socket Type" + mSocketType + "close() of server failed", e); } } }
