Question

我在Android studio中使用Firebase为我的App创建了一个通知系统。该应用程序有一个小缺陷。

当应用程序在屏幕上可见时，它正常工作，图标显示为应该和大图像。请参见下面的屏幕截图。

当关闭应用程序并发送通知时，会出现崩溃，图标显示为球，并且不会显示大图像。请参见下面的屏幕截图。

我将发布我正在使用的代码。如果有人已经通过这个并且可以帮助我，我将非常感激。

的AndroidManifest.xml

将此添加到您的应用程序manifest.xml文件中。这将在应用处于非活动状态时设置通知的小图标。

<meta-data
    android:name="com.google.firebase.messaging.default_notification_icon"
    android:resource="@drawable/ic_stat_ic_notification" />

Firebase通知，图标和大图片中出现小故障
