当应用程序关闭时，Android 不会收到来自 Parse Push 的推送通知 [英] Android doesn't receive push notification from Parse Push when app is closed

问题描述

当我在 Android 手机上测试 Parse Push 时，只要应用程序运行，推送通知就会出现.如果应用程序已关闭:我只会收到一条消息，内容为 已停止. - 我没有收到任何推送 - 但仍然收到停止通知弹出窗口.我一步一步地遵循了 Parse 的快速入门指南.

When I am testing the Parse Push to my Android phones the push notification come through as long as the app runs. If the app is closed: I just get a message saying <App name> has stopped. - I don't receive any of the pushes - but still got the stop notification popup. I have followed the Quickstart guide from Parse step by step.

推荐答案

在 Application 类中初始化解析，如下所示

Have the parse initialized in Application class similar as below

public class AppClass extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        // Parse.enableLocalDatastore(this); // if you need this, put before init
        Parse.initialize(this, "gV6QK", "JJmFo99");
        PushService.setDefaultPushCallback(getApplicationContext(), MainActivity.class);
        ParseInstallation.getCurrentInstallation().saveInBackground();
    }
}

不要忘记在清单中引用您的应用类

Don't forget to reference your app class in manifest

<application android:name=".AppClass">

从 MainActivity 中删除 Parse init

Remove Parse init from MainActivity
