AndroidStudio中修改api帮助文档本地路径问题

最近更了一波Android Studio,更新之后又添加了很多功能，但是在使用过程中有一个很让人恼火的问题，按了查看api文档的快捷键后要先fetching document…一会儿才能看到，这简直是大大的有损开发效率，于是去了一趟google官网，查了下怎么设置参考文档的本地路径，成功解决了这个问题，这里做一个简单的说明：

　Solution:

　找到AS配置文件文件，一般在：

　

windows下：系统盘:C:\Users\username\.AndroidStudio2.3\config\options

Mac下：~/Library/Preferences/AndroidStudio2.3\config\options

用编辑器打开options目录下的jdk.table.xml文件，会看到xml文件结构如下：

<application>
<component name="ProjectJdkTable">

</jdk>

</component>
</application>

将我注释的android api参考文档路径的地方改为sdk的安装目录下即可：SDK_INSTALL_DIR\docs\reference

完成改动后重启AS就好了，当然可以断网测试是否设置有效。如果还是fetching documeng…很慢，很乐意交流解决问题。
