我正在运行一个针对Android 19的反构建项目。我正在尝试使用在Android 5.0发布的Android设计库中引入的TabLayout。
当我尝试从命令行构建我的项目时，我发现Android设计库需要appcompat。我添加了appcompat，我删除了v21和v23的资源文件夹，因为我的应用程序只支持v19(它给了我错误)。我设法让Appcompat构建使用ant调试，但当我试图构建设计库，我得到错误

没有引用appcompat，我从做同样的事情得到这个(这就是为什么我添加了appcompat，尽管它从未被提及)

我试过删除/gen和做更新库项目和清洁，但无济于事。
对于appcompat，我已经在project中列出了依赖项。像这样的属性
target=android-19
android.library.reference.1=../appcompat/
- 为什么我得到这个错误
- 与Android 5.0一起发布的Android设计库需要Android 5.0吗?(这将解释我的问题)
- 在appcompat中删除v21, v23资源文件夹是否安全，以便我可以使用目标19构建它?
为什么我得到这个错误
将target更改为android-23。你的构建目标(在Android Studio中被称为compileSdkVersion)应该与你正在使用的Android支持库匹配。
Android 5.0发布的Android Design Library需要Android 5.0吗?
。我敢说，它可以回到API级别7，就像appcompat-v7一样。它需要针对较新版本的Android进行编译，因为它在较新的Android设备上运行时有条件地使用较新Android版本的api。
