Android FCM 通知不会推送 API 25-

Question

我正在尝试将 firebase 云消息传递添加到我的项目中。问题是我想在设备处于 sleep 状态或应用程序处于后台时推送通知。 Firebase 文档说，当您在应用程序不在前台时发送通知时，系统会完成这项工作，但为什么它适用于 API 26 而不是 API 25 更低的版本？

前台应用程序中的通知由我处理并且工作正常，我的目标 API 是 26 - 编译的 SDK 26.0.2 并使用最新版本的 FCM pkg。

我的测试设备是带有 API 19、22、25、26 的 adbs和带有 API 25 的 Xperia X，三星 S8 API 26

我发送的通知 JSON:

    {
    "to" : "existing key",
    "condition" : null,
    "collapse_key" : null,
    "priority" : "high",
    "content_available" : null,
    "time_to_live" : 3600,
    "restricted_package_name" : null,
    "dry_run" : null,
    "data" : null,
    "registration_ids" : null,
    "notification" : {
        "title" : "ViLo Testzor",
        "body" : "Alarm. ",
        "sound" : null,
        "icon" : null,
        "tag" : null,
        "color" : null,
        "badge" : null,
        "bodyLocKey" : null,
        "bodyLockArgs" : null,
        "clickAction" : null,
        "titleLocKey" : null,
        "titleLocArgs" : null
        }
    }

非常感谢 Radek 的每一个回复。

Answer 1

在您的情况下，如果您的应用程序处于后台或处于终止状态，Firebase 将不会调用 onMessageReceived()。

要在后台或被杀死状态下获取通知，请使用data 对象而不是notification 对象。

以下将起作用:

{
"to" : "existing key",
"condition" : null,
"collapse_key" : null,
"priority" : "high",
"content_available" : null,
"time_to_live" : 3600,
"restricted_package_name" : null,
"dry_run" : null,
"data" :  {
    "title" : "ViLo Testzor",
    "body" : "Alarm. ",
    "sound" : null,
    "icon" : null,
    "tag" : null,
    "color" : null,
    "badge" : null,
    "bodyLocKey" : null,
    "bodyLockArgs" : null,
    "clickAction" : null,
    "titleLocKey" : null,
    "titleLocArgs" : null
    },
"registration_ids" : null,
"notification" :null
}
