Droidin Pro is next generation of the first ever LinkedIn Android application which is fast, native Android client (not a web app) driven by the LinkedIn Open API. Pro version removes Google ads and any limits from the free version
Please note that this is a license only. It is very small so it won't clatter your app space. Right now (subject to change) it requires you to have free Droidin installed as well. Once both apps are installed you can start Pro from ether shortcut.
