android studio导jar包找不到类的解决方法
今天更新了universal-image-loader-1.9.5.jar文件,studio死活找不到其中相关的类,上网百度试了很多办法,总算解决了,具体方法跟一篇老外的帖子的差不多,这里分享下。
解决步骤:
Something went wrong in incremental build system. One of this should help:
- Menu Build -> Rebuild project
- Delete folder /build
- Close Android Studio, delete /build folder
- Right click on your project -> "Open module settings" -> Dependencies tab -> check if Export is checked for your library

这个问题经常发生在build.gradle如下配置的时候:
compile fileTree(dir: 'libs', include: ['*.jar'])
如果实在解决不了,就在build.gradle里面加上比如下面的引用,studio可能有时候发现不了jar包,加上下面的代码就能骗过studio了,bulid成功后删除就好了。
compile files('libs/umeng_social_sdk.jar')
