Getting java.lang.ClassNotFoundException (Unable to instantiate activity ComponentInfo)

[Jerrell Mardis]

I've seen the following error a few times during the development cycle and now I just received an error report. I have no idea what's causing this. After reading similar questions on stackoverflow regarding this issue, I double checked my AndroidManifest and everything looks fine to me. Any ideas on what could possibly be causing this exception?

Another thing to note is that I'm using a few open-source libs that may be causing the issue but I'm not sure:

android-support-v4-googlemaps lib found at https://github.com/petedoyle/android-support-v4-googlemaps which allows me to embed a MapView in a Fragment (along with the ActionBarSherlock lib), ActionBarSherlock, Android-ViewPagerIndicator, AndroidBillingLibary (https://github.com/hpique/AndroidBillingLibrary) and a couple more.

This exception seems like a dependency issue and I'm not sure if it's related to how I'm using the above mentioned libs.

Here's the stack trace as well as the manifest file.
