R文件未生成 [英] R file not generated

问题描述

我知道很多类似的问题已经被问到，例如这个一。矿略有不同。我使用所有的默认设置创建一个新的android项目（目标SDK 4.2 Jelly Bean，min SDK 2.2 Froyo）。创建该项目没有R文件。我尝试清理项目，没有任何反应。我尝试在res文件夹中查找错误，没有发生任何事情。我所有的XML文件名都是小写。我可以搞砸导致全新的项目不生成R文件？有没有需要修复的Eclipse配置？有没有一些我没有安装的Android模块？任何帮助将不胜感激。

I know many similar questions have been asked for example this one. Mine is slightly different. I create a new android project using all the default settings (target SDK 4.2 Jelly Bean, min SDK 2.2 Froyo). The project is created without an R file. I tried cleaning the project and nothing happens. I tried looking for errors in the res folder and nothing happened. All my XML file names are lower case. What could I have messed up to cause brand new projects to not generate R files? Is there some Eclipse configuration that needs fixing? Is there some Android module that I haven't installed? Any help would be greatly appreciated.

推荐答案

确保您已经从sdk管理器安装了 android sdk构建工具，如果您已更新adt to rev 22
安装它重新启动eclipse并进行清理和重建项目它将工作

make sure you have android sdk build tools installed from the sdk manager if you have updated adt to rev 22 Install it resart the eclipse and make clean and rebuild project it will work
