Question

我正在创建一个具有空活动的新项目，最低 API 级别为 24，并启用支持库。 当我在模拟器上运行它时它可以工作，但是当我在摩托罗拉 g4（这是我的目标设备）上运行它时，我得到了这个错误）。

目标AAPT: error: resource android:attr/colorError not found （由.gradle/caches/transforms/.../appcompat-v7-28.0.0/res/values-v26/values-26.xml Studio设置为29. .gradle/caches/transforms/.../appcompat-v7-28.0.0/res/values-v26/values-26.xml 。 尝试删除缓存并重新构建，但同样发生。

原始错误的堆栈跟踪是

SDK 目标的最低版本是 28，如果您使用下面的一个，Play 商店将不允许您上传 apk。

尝试从 sdk 目标 28.0.0 访问资源时出现错误。

这是官方文档： https://developer.android.com/distribute/best-practices/develop/target-sdk
