如何在 Android Studio 中检查代码指标（代码行数、死代码行数、圈复杂度等）

Question

我在 Android Studio 中计算代码指标时遇到一些问题。我发现 Metrics Reloaded，但我的 Android Studio 无法使用它们（加载此插件时它总是向我显示错误）。

在 Google 搜索中，我没有找到任何不同的插件或类似的东西。还有什么或者有人知道哪里可能有错误吗？

错误：

您也可以尝试安装 Jetbrains Statistics 插件，如本回答中所述： Count lines of code in all java classes in Android Studio
