Android java.lang.IllegalArgumentException: 路径必须是凸的
Android java.lang.IllegalArgumentException: path must be convex
相同的应用程序在 Android 7 中工作但在 Android 8 中失败。
在 activity 我正在从 Fire-base 数据库中检索数据。当 Fire-base 数据库为空时没有发生错误，当它有数据时发生错误，我搜索错误但没有找到任何解决方案。

- 第 3 行提到
AdaptiveIconDrawable
- 第 7 行提到
View.drawBackground()
搜索 AdaptiveIconDrawable 告诉我们这是一个新的 Android 8 功能：
这解释了为什么您的代码在 Android 7 上运行但在 8 上崩溃。在 Android 7 上，系统不使用自适应图标，而是使用普通的 PNG。在 Android 8 上，如果您提供了自适应图标，它将使用自适应图标。
新图标似乎有问题，或者它在您使用它的地方不起作用。
接下来我们需要找出是什么背景被破坏了...
查看您的 CardView 布局，您正在将启动器图标（在 Android 8 上这可能是您的 AdaptiveIconDrawable）设置到 CircleImageView 背景上。
这就是崩溃发生的地方 - 图标无效，或者 CircleImageView 在以这种方式使用时不支持它。
解决方法是在您的应用中包含一个 PNG 图标，在这种情况下用作背景。
假设您的图标设置正确，请尝试使用 android:src 而不是 android:background 为 CircleImageView 设置图标。
