在我的 android 代码（Kotlin）中，我使用 java iterable 的 forEach 方法。

mandatoryViews.forEach { view ->
   // my code here
}

下面是我在 build.gradle (app) 中的 sdk 配置：

minSdkVersion 23
targetSdkVersion 30

现在我的代码构建得很好。我还尝试在 API 23 像素设备上运行它，一切正常。

但在我运行gradlew lint查看 lint 错误后，它失败并报告给我以下错误： Call requires API level 24 (current min is 23): java.lang.Iterable#forEach

无法弄清楚为什么 lint 认为它在 API 23 上不起作用，而在 API 23 设备上我的代码运行良好。

我在启用 R8 的情况下构建发布 apk 时遇到以下错误：
