Android 如何将在平板电脑中运行的应用程序运行到智能手机？

我对安卓非常陌生，我被分配了一个在平板电脑上工作的系统项目，我的想法是它也可以在智能手机上工作。据我所见，它是用API 13开发的，我会把它带到API 19，但给了我一些错误：

C:\Projects\TestAndroid\app\build\intermediates\res\merged\debug\values-v21\values-v21.xml

有人知道处理这个问题的材料吗？非常感谢。

只需删除

\res\values-v21\

文件夹。当您的目标API级别为19时，您将不需要它。（材料设计主题需要API级别21）

嗨，Michael，我仍然有这个问题。你需要“重建”项目。（菜单：构建>重建）
