Google play licensing
<p>I'm trying to use google play licensing, but i'm not able to start using it.</p>

<p>I'm following this guide <a href="http://developer.android.com/google/play/licensing/setting-up.html#runtime-setup" rel="nofollow">http://developer.android.com/google/play/licensing/setting-up.html#runtime-setup</a>.
I'm stuck here: "Copying the LVL sources to your application". When i copy the folder library\src\com into my src folder of my project, i get a lot of error on all the classes I imported 
What am i doing wrong? </p>
