当 foreground_show 设置为 false 并且我的应用程序在后台时，如何获取推送通知以显示？

[英]How do I get push notifications to show when foreground_show is set to false and my app is in the background?

问题描述

我正在尝试以这种方式在华为设备上实现推送通知：

目标

(1) 当我的应用程序在前台（活动）时，我希望它透明地处理推送消息而不显示弹出系统通知。

(2) 当我的应用程序未启动或在后台时，应显示标准弹出窗口。 点击弹出窗口打开我的应用程序，传递数据消息中的数据，以便我的应用程序可以处理它。

执行

通过设置foreground_show: false，我能够实现（1）。 但是，对于 (2)，当我的应用程序未处于活动状态时从我的服务器发送推送通知时，设备上什么也没有发生！

我的 logcat 输出（详细）：

我的代码

我通过 REST 调用发送到华为 API 的 JSON 对象的有效负载：

{
    validate_only: false,
    message: {
        android: {
            notification: {
                foreground_show: false,
                title: "My title",
                body: "Message body",
                click_action: {
                    // 1 = opens a custom app page. foreground_show: false requires this!
                    type: 1,
                    action: "com.huawei.codelabpush.intent.action.test",
                }
            }
        },
        token: [ 'myDeviceTokenHere' ],
    }
}

根据我的研究，这可能与我的 AndroidManifest.xml 文件有关。 特别是，我在活动标签下设置了导出：true ：

问题

如何解决我的应用程序在后台时不显示通知的问题？

3 个解决方案

根据您提供的日志，建议您检查通知栏点击事件中要打开的activity是否设置了permission或exported = false 。

解决方案2

Android 清单文件不包含过滤器以获取推送消息通知部分。

您能否确认是否在处理清单文件中的推送通知的活动中添加了权限属性（android:permission = "abcd"）？ 请删除此属性并在后台重试推送通知。 根本原因是由于权限问题，通知中心无法将消息传递给适当的应用程序/活动。 上述解决方案只是一个例子。

从华为推送服务获取消息内容的最简单方法是使用数据消息而不是通知消息。 您可以使用键值对从服务器发送数据消息，并在 onMessageReceived() 方法中捕获此消息。 捕获此消息后，您可以使用 Android 通知显示通知，或者您可以做任何您想做的事情。

要检查应用程序是否正在运行，您可以在 App 类中定义一个静态布尔变量，并在应用程序运行时使其为真。 您可以根据该变量的状态决定是否显示通知。
