Build path incomplete only in some workspaces (Android)

Question

I have multiple Eclipse (3.52 \"Galileo\") ) workspaces so that I can keep related projects together in the same workspace. I switch between them with File > Switch Worksp

Answer 1

In my case this issue happens after I install ADT manually by downloading .zip instead install from ADT site.

I solve the issue by right click on project -> Java Build Path. You'll see Android XXX, Android Dependencies, Android Private Libraries, Expand and click on Native library location (None), click edit button on right side then add path to ADT folder on eclipse on Location Path. Restart eclipse to complete
