未收到通知

Question

我们正在使用解析存储聊天消息，我们正在使用解析通知。

对于iOS，我们这样做是为了在Parse的安装表中创建条目…它在parse的安装表中创建条目，我认为这是接收通知所必须的。

 PFInstallation *currentInstallation = [PFInstallation currentInstallation];

 currentInstallation.deviceToken = user.notificationToken;

[currentInstallation saveInBackground];

我没有收到来自解析的通知，我认为这是没有收到通知的原因…

事实是这样的吗？

有谁能帮我走上正路吗？

更新

现在收到通知但仍有些疑虑。我在用户登录时执行此操作。我有放条件，如果用户没有创建，那么只有创建，否则不。我没有把它加进去，因为那不是必要的

   // setting up parse installation
private void setUpParseInstallation()
{

    ParseInstallation currentInstallation = ParseInstallation
            .getCurrentInstallation();

    currentInstallation.saveInBackground(new SaveCallback()
    {

        @Override
        public void done(com.parse.ParseException e)
        {
            if (e != null)
            {
                Log.e(TAG, "Error saving parse installation");
            }
        }
    });
}




// add user to parse it it doesn't exist otherwise handle the cases
private void addUserToParseIfNotExisting()
{

            // if user doesn't exist create a new user
        ParseObject newuser = new ParseObject("user");
            newuser.put("name", email);
            newuser.put("userId", id);

            newuser.saveInBackground();
}


private void setChannel()
{
     channel = "abdf";
         RS_User user = new RS_User(this);

    ParseQuery<ParseObject> pquery = ParseQuery.getQuery("user");

    pquery.whereEqualTo("userId", user.getUserId());

    // see if user exists in user table on parse
    pquery.findInBackground(new FindCallback<ParseObject>()
    {

        @Override
        public void done(List<ParseObject> list,
                com.parse.ParseException error)
        {

            if (list.size() > 0)
            {
                        list.get(i).put("channels", channel);
                        list.get(i).saveInBackground();
                                            PushService.subscribe(getApplicationContext(),channel, RS_HelpActivity.class);

            }
       } 
   });
}

发送通知

ParsePush push = new ParsePush();
                                if(object.get(k).has("channels"))
                                {
                                    push.setChannel(object.get(k).getString(
                                            "channels"));
                                }
                                push.setData(dataAndroid);
                                push.sendInBackground();

希望这段代码对您有所帮助

public class Application extends android.app.Application {

  public Application() {
  }

  @Override
  public void onCreate() {
    super.onCreate();

    // Initialize the Parse SDK. 
    Parse.initialize(this, "your applicationId", "your clientKey"); 

    // Specify an Activity to handle all pushes by default.
    PushService.setDefaultPushCallback(this, MainActivity.class);
  }
}

<application
    android:name="<Your Package Name>.Application"
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
