场合

我已经在 ANDROID 中使用Parse实现了推送通知。一切都很好（我可以接收推送/发送等），唯一的一件事就是当我安装我的应用程序时，它会发生这样的事情：

如果它是设备上的第一次安装：没问题
如果不是第一次安装（这意味着设备已经进行了PARSE / GCM注册），则会生成此错误：

是的，它会生成它，但应用程序不会崩溃！该应用程序仍然有效：推送通知，但您可以理解这不是100％可靠。

E/ParseCommandCache﹕ Failed to run command.
com.parse.ParseException: at least one ID field (installationId,deviceToken) must be specified in this operation

他想要什么......？我该怎么办？问题的原因是什么？这是我的代码：

Application.java

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

    // Initialize the Parse SDK.
    Parse.initialize(this, "x", "x");

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

    ParseInstallation.getCurrentInstallation().saveInBackground();

}

在我的mainActivity中，我只是将deviceToken（在我的情况下是installId）连接到我的userAgent：这也很好用！即使生成错误，也会将installID插入userAgent。

MainActivity.java

 deviceToken = ParseInstallation.getCurrentInstallation().getInstallationId();
 webSettings.setUserAgentString(userAgent + " ||" + deviceToken);

我在代码中犯了什么错误吗？

谢谢

Answer 1

请尝试以下方法：

 ParseInstallation.getCurrentInstallation().saveInBackground(new SaveCallback()
    {
        @Override
        public void done(ParseException e)
        {
            PushService.setDefaultPushCallback(Application.this, MainActivit.class);
        }
    });

Answer 2

我记得，使用setDefaultPushCallback时不需要保存安装。尝试删除保存安装，看看它是否仍然存在。

setDefaultPushCallback会自动为您保存安装。不记得我发现它的位置，但在一些论坛上它被告知是行为。我想在第二次保存之后（没有第一次完成）会使安装处于错误状态，导致非致命错误消息。
