Aplicación de congelación de socket Android Bluetooth

Tengo un problema extraño con el zócalo del bluetooth. Si creo el zócalo y después cierra la aplicación, el dispositivo androide congela con la carga muy alta de la CPU.

Aquí mi código de ejemplo:

• Android: socket bluetooth se niegan a conectarse correctamente
• Cierre el zócalo al terminar la aplicación
• Conexión Bluetooth de Android: falla en la detección del servicio
• Sockets sin procesar en Android
• Dispositivos Android conectados con NSD, cómo enviar mensajes utilizando sockets (Client-Client)?

// open socket public ConnectThread(final BluetoothDevice device) { Log.v(ConnectThread.class.getName(), "Try to get a socket"); try { this.socket = device.createRfcommSocketToServiceRecord(UUID.fromString("00001101-0000-1000-8000-00805F9B34FB")); } catch (IOException e) { Log.e(ConnectThread.class.getName(), e.getMessage()); } Log.v(ConnectThread.class.getName(), "Got a socket"); } // close it public void cancel() { try { Log.v(ConnectThread.class.getName(), "cancel"); this.socket.close(); } catch (IOException e) { Log.e(ConnectThread.class.getName(), e.getMessage()); } } 

Dispite que cierro el socket con el método close() , no entiendo por qué el dispositivo Android se congela después de cerrar mi aplicación. Tenga en cuenta, que sólo socket creado, pero no conectado …

EDITAR:

Aceptar, hay código de ejemplo:

 package com.ss.test; import java.io.IOException; import java.util.UUID; import android.app.Activity; import android.bluetooth.BluetoothAdapter; import android.bluetooth.BluetoothDevice; import android.bluetooth.BluetoothSocket; import android.os.Bundle; import android.util.Log; public class testBump extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); BluetoothDevice device = this.bluetoothAdapter.getRemoteDevice("58:B0:35:6F:8E:C7"); Log.e(testBump.class.getName(), "Try to get a socket"); try { this.socket = device.createRfcommSocketToServiceRecord(UUID.fromString("00001101-0000-1000-8000-00805F9B34FB")); } catch (IOException e) { Log.e(testBump.class.getName(), e.getMessage()); } Log.e(testBump.class.getName(), "Got a socket"); Log.e(testBump.class.getName(), "DESTROY"); try { this.socket.close(); } catch (IOException e) { Log.e(testBump.class.getName(), e.getMessage()); } Log.e(testBump.class.getName(), "DESTROYED"); } @Override public void onDestroy() { super.onDestroy(); } private BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); private BluetoothSocket socket = null; }

Como se puede ver en el registro, el zócalo se cerró correctamente. Ahora, salga de la aplicación (se ejecutará en segundo plano), ejecute el Administrador de tareas y eliminar la aplicación. En ese momento, el dispositivo Android se congelará con una carga de CPU muy alta.

EDIT 2:

Encontré, ese problema se reproduce en el dispositivo Samsung GALAXY Tab sólo. Por ejemplo, no puedo reproducirlo con mi HTC Desire.
