Android Studio集成SVN插件，check out出代码后，每次开启都会在右上角出现如下错误：
Can't use Subversion command line client: svn Probably the path to Subversion executable is wrong. Fix it.
Errors found while svn working copies detection. Fix it.
下面直接上解决方案吧：
1、安装客户端http://ncu.dl.sourceforge.NET/project/tortoisesvn/1.8.7/Application/TortoiseSVN-1.8.7.25475-x64-svn-1.8.9.msi
http://jaist.dl.sourceforge.Net/project/tortoisesvn/1.8.7/Language%20Packs/LanguagePack_1.8.7.25475-x64-zh_CN.msi注意：安装时候必须选中command line 。。。这个选项
2、打开AS，Go to settings - > Version control -> Subversion，在这里面将左边的三个复选框给勾选掉，如图
3、重启AS开发工具即可。
