android - Broadcastreceiver组件不允许绑定(bind)到android中的服务

Question

这是我正在做的:

public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub

        ConnectivityManager conn = (ConnectivityManager) context
            .getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = conn.getActiveNetworkInfo();
    boolean isConnected = activeNetwork != null
            && activeNetwork.isConnectedOrConnecting();

    if (isConnected == true) {

        // initChatHub();
         Intent serviceIntent = new Intent(context, ChatService.class);
        Toast.makeText(context, "Connected", 1000).show();
        serviceIntent.putExtras(intent);
        context.startService(serviceIntent);
        context.bindService(serviceIntent, mServiceConnection,
                Context.BIND_AUTO_CREATE);

    } else {
        Toast.makeText(context, "Disconnected", 1000).show();
    }
}

当网络状态发生变化时应用程序崩溃当我关闭数据连接时没有错误出现当数据连接打开然后应用程序崩溃并且出现此异常请建议我如何修复它。

请参阅此处 Context.bindService :

Note: this method can not be called from a BroadcastReceiver component....

所以，使用 BroadcastReceiver.peekService从运行的服务中返回 IBinder:

 Intent serviceIntent = new Intent(context, ChatService.class);
 context.startService(serviceIntent);
 if (isConnected == true) {
  IBinder binder = peekService(context, new Intent(context, ChatService.class));
  Toast.makeText(context, "Connected", 1000).show();
  if (binder != null){
    mChatService = ((LocalBinder) binder).getService();
        //.... other code here          
  }
}
