Question

这个问题已被问过几次，但它从来没有得到妥善回答，也无法找到合适的解决方案。

我在我的应用中实现了FCM，当应用处于前台时，FCM也正在运行。但是一旦它处于背景或关闭状态，一切都变得混乱。我知道数据有效负载如果在后台没有来，但如果应用程序不在前台，则根本不会调用onMessageReceived。

它将通知发送到系统托盘并且android显示它，但我需要设计通知，更重要的是我需要一些功能，当通知命中时，根据某些条件导航到特定屏幕。

Whatsapp和Gmail如何做这些事情？

请在标记此副本或关闭之前帮助我...任何有用的想法。

如果我错过了通知部分的任何内容，请告诉我。数据部分工作正常。通知触发时如何在后台同步某些数据。

对于低于4.4的设备的通知的任何更新？它根本不会收到通知。有什么问题吗？

应用程序在后台时未调用FCM通知方法
