Question

在Android Studio中，我正在为minSdkVersion 19开发，当我将其更改为21时，我的所有布局都出现以下错误：

我的每个布局都显示完全相同的错误。所以我回到了minSdkVersion 19，但例外仍然存在。我尝试在gradle中添加几个支持库，但没有一个工作。我做错了什么想法？

我遇到了同样的问题。我刚刚将android.support.v4的版本从25.0.1更新为27.0.1并且工作正常

java.lang.ClassNotFoundException：android.support.v4.view.TintableBackgroundView
