Android Studio一直 Fetching Documentation...

Android查看私有库android-spport-v4.jar & android-support-v7-appcompat.jar源码

https://www.cnblogs.com/stupid-bird/p/4614490.html

2. Android-support-v7-appcompat.jar查看源文件
Android-support-v7-appcompat.jar查看源文件的方法和上面同样道理，新建Android-support-v7-appcompat.jar.properties文件，添加src=D:\DevAPP\Android\android-sdk\sources\android-22 即可。没错，他们的src路径是相同的，不用怀疑。
