推荐答案
你甚至尝试谷歌呢？ 从 http://developer.linkedin.com/docs/DOC-1255 我们得到了 HTTP：//$c$c.google.com/p/linkedin-j/
did you even try google it ? from http://developer.linkedin.com/docs/DOC-1255 we got http://code.google.com/p/linkedin-j/
编辑： 这里是我的示例项目 http://esilo.pl/LITest.zip
here is my sample project http://esilo.pl/LITest.zip
EDIT2：最少的样品，与存储在共享preferences标记的（所以你不必每次都做授权（我会更新LITest.zip））
minimal sample, with tokens stored in SharedPreferences (so you don't need to do authorization every time(i'll update LITest.zip))
EDIT3：AsyncTask的code加入...避免NetworkOnMainThreadException：）
