问题描述

我检查出不同的PC旧的Andr​​oid项目，我得到一个 安卓pre编译器空指针异常错误，每节省这么R.java不能生成。该项目是使用其他库的库项目。

I check out the old android project on a different pc and I get a Android Pre Compiler Null pointer exception error, on every save so R.java can't be generated. The project is a library project using other library to.

新项目所在不工作的制度： 64位Ubuntu的， ADT日食， Android的SDK工具21.0.1， Android的SDK平台工具16 错误是：

The new where the project is not working is system is: 64 bit ubuntu, ADT eclipse, Android sdk tools 21.0.1, Android sdk platform-tools 16 the error is:

该项目工作在一个旧的系统：

The project works on a old system:

旧系统： 32位Ubu​​ntu的， 4.2.1蚀朱诺， Android的SDK工具21，

The old system is: 32 bit ubuntu, 4.2.1 eclipse Juno, Android sdk tools 21,

的Git作为版本控制系统。 这是一个很奇怪的问题我已经checkt所有的XML与皮棉运行它们找到一个XML构建问题，但对每一个没有运气救我有同样的错误，不产生R.java。谢谢

Git is used as a version control system. It is a very strange problem I have checkt all of the xml run them with lint to find a xml build problem but no luck on every save the i have the same error and the R.java is not generated. Thanks

推荐答案

在21.0.1 Android的pre编译器似乎受到严重破碎，拍击的.svn目录和.DS_Store文件和文件，而无需文件扩展名。

The Android Pre Compiler in 21.0.1 appears to be badly broken, crashing on .svn directories and .DS_Store files, and files without file extensions.

这是为我工作的解决方案是升级到21.1 RC1以下步骤： 这里1.按照指令： http://tool​​s.android.com/$p$pview-channel 2.确保同时更新SDK管理器和ADT 3.重新启动Eclipse的

The solution that worked for me was to upgrade to 21.1 rc1 following these steps: 1. Follow instructions here: http://tools.android.com/preview-channel 2. Make sure to update both SDK Manager and ADT 3. Restart Eclipse
