ADT17 bug: "java.lang.NoClassDefFoundError"

After successful build of Android application it crashes with error:

java.lang.NoClassDefFoundError: com.google.android.apps.analytics.GoogleAnalyticsTracker

Or some other class. Probably you have installed new ADT17 update. ;)

Resolution: Move \lib to \libs folder.
