I want to integrate my Android application with LinkedIn and post a message. Can anyone provide an example for how to do this?
did you even try google it ? from http://developer.linkedin.com/docs/DOC-1255 we got http://code.google.com/p/linkedin-j/
EDIT: here is my sample project http://esilo.pl/LITest.zip
EDIT2: minimal sample, with tokens stored in SharedPreferences (so you don't need to do authorization every time(i'll update LITest.zip))
EDIT3: AsyncTask code added ... to avoid NetworkOnMainThreadException :)
