Question

我想在后台或在应用程序中处于活动状态时在应用程序中显示通知

我可以获取令牌并在控制台Firebase中手动发送它，并且可以正常运行，因为我看到状态已完成，但是应用程序出现了此问题

我正在使用

react-native-fcm，

react-native-firebase

这是AndroidManifest.xml文件

错误消息表明您缺少图像和颜色。最好添加这些。

转到/android/app/src/main/res/mipmap-*文件夹并创建ic_launcher.png的副本，并将其命名为ic_notif.png。另外，在/android/app/src/main/res/drawable-*文件夹中创建一个副本（如果不存在，则创建它们（drawable-mdpi，drawable-hdpi等），并命名图标ic_stat_ic_notification.png的副本。创建文件/android/app/src/main/res/values/colors.xml并将其添加为内容：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorAccent">#FF0000</color>
</resources>

这应该会使错误消失。您可能错过了安装push模块代码的一些步骤。
