层保存标志无效-Android 9只允许所有保存标志

当我将targetSdkVersion更新到28时，我遇到了以下错误，这个应用程序在以前的版本中运行得非常好，但在android 9中尤其如此。我看到几个github链接，其中提到基本参考书目已更新为6.0.8，我不理解。有人可以告诉我怎么修。我正在附加Android Studio控制台中的错误

我也有同样的问题。这似乎是安卓9的问题。通过以下方式解决此问题：

implementation 'com.airbnb.android:lottie:2.7.0'

---

我希望它能有所帮助。

通过使用in-build.gradle解决了这个问题：

targetSdkVersion 27

---

我对Glide SVG loader也有同样的问题。要解决此问题，您可以迁移到AndroidSVG的最新版本1.4

我将版本更新为

实现'com.caverock:androidsvg aar:1.4'

---

这个问题对我来说似乎已经解决了。

谢谢你的回答，我会尝试的，因为我尝试了所有方法，但没有找到解决方案。您好，您尝试了解决方案吗？是的，很抱歉回复太晚，但它非常有效@JohanFick
