Android Studio 构建问题：Task :app:checkDebugAarMetadata FAILED

Question

我刚刚创建了一个新的 Android Studio 项目，放置了两个按钮并想运行该应用程序。但它并没有像上次那样成功并抛出这些错误消息：

''' FAILURE：构建失败并出现异常。

• 出了什么问题： 任务“:app:checkDebugAarMetadata”执行失败。

执行 com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction 时发生故障 检查 AAR 元数据值时发现的一个或多个问题：

我也卸载了 Android Studio，但没有成功。有谁知道该怎么做？我对 Android Studio 和 Gradle 还是很陌生。谢谢！

Answer 1

minCompileSdk 为 31，但 minSdkVersion 明显更低。增加项目的 compileSdk 足以解决问题。

android {
    compileSdk 31
...
}
