Updated SDK version, getting ClassNotFoundException: android.support.v4.view.ViewPager
When i was working on my Anroid project i found Logcat to be annoying (not keeping the scroll bar at a given point) and read that updating SDK versions adds a pause button to combat this issue. I updated to SDK version 17 and now i am having some strange problems that i didn't have before. I deleted and added the android support library but no luck. Ive been reading around the interwebs but i still cant figure it out. Log is below.
