我需要在通知出现在我的 android 应用程序中时打开特定片段，当应用程序在通知到来时被杀死或关闭时，单击通知我需要打开片段并调用 api 这是我的代码。当我的应用程序当时处于运行状态时，通知来了，但没有显示在通知栏上

    if (bundle != null) 

        String value = bundle.getString("api_url");

        Toast.makeText(this, value, Toast.LENGTH_SHORT).show();

【问题讨论】：

您只需要从 FCM 获取 data 类型的通知，即使在应用程序被终止时也能接收通知。

你好，你能把你的通知json数据粘贴到这里吗？

【参考方案1】：

您广播了通知。因此，您的应用不会在通知托盘上显示通知。
