android - Sinch Service 好像没有启动 Android Studio 和 Parse.com (Android Messaging Tutorial)

Question

我正在学习本教程:https://www.sinch.com/tutorials/android-messaging-tutorial-using-sinch-and-parse

Github 教程:https://github.com/sinch/android-messaging-tutorial

我遇到的问题是该服务似乎根本没有启动。我已经检查了代码，但没有发现任何看起来不对的地方(但话又说回来，我是初学者，哈哈)。

我在 MenuFragment3 类中没有收到任何广播，因此 progressDialog 一直在旋转。我还检查了一项服务是否同时在多个模拟器和真实设备上运行，就像我说的那样，服务似乎永远不会启动，我真的不明白为什么。

如果您需要更多信息，请告诉我，感谢您的帮助!

首先我在用户登录时启动服务:

serviceIntent = new Intent(getApplicationContext(), MessageService.class);
startService(serviceIntent);

这是 list :

<?xml version="1.0" encoding="utf-8"?>

这是 MessageService 类:

    Parse.initialize(this, "thisiscorrect", "thisiscorrect");

    currentUserId = ParseUser.getCurrentUser().getObjectId();

    if (currentUserId != null && !isSinchClientStarted()) {
        startSinchClient(currentUserId);

    broadcaster = LocalBroadcastManager.getInstance(this);

    }

    public boolean isSinchClientStarted() {

这里是教程中我的 ListUsersActivity 版本(对我来说，它称为 MenuFragment3，它是从 StudentLogged 或 LectureLogged Activity 调用的滑动菜单的一部分)

package com.yupo.dominic.yupo;

您正在尝试使用您的 Sinch key 和 secret 来初始化 Parse。此外，您应该在应用程序的 onCreate 方法中初始化 Parse。尝试:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    currentUserId = ParseUser.getCurrentUser().getObjectId();

    if (currentUserId != null && !isSinchClientStarted()) {
        startSinchClient(currentUserId);
    }

    broadcaster = LocalBroadcastManager.getInstance(this);

    return super.onStartCommand(intent, flags, startId);
}
