如何将对象从服务传递给调用活动

Question

我正在使用Chat messenger。我使用了socket.io-client库。我已经创建了一个实例化Socket类的服务。

SocketService.java

    public class SocketService extends Service {

    public static Socket mSocket;

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        if (intent != null) {
            String data = intent.getStringExtra("Socket");
            Log.e("intent data", data);
            Log.e("Service", "Called");
        }
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Log.e("Service", "created");
        try {
            mSocket = IO.socket(Constants.CHAT_SERVER_URL);
            Log.e("ValueSocket", String.valueOf(mSocket));

        } catch (URISyntaxException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }
}

我在SplashActivity.java中启动服务。我必须将Socket实例即mSocket传递给Activity SplashActivity.java。如何才能在android中实现这一点？请帮忙。
