android_tutorial_pubsub errors in eclipse and adb logcat

edit

I can rosmake, ant, and ant debug android_tutorial_pubsub without error. I can install the .apk on my android phone just fine, but when I attempt to run the app, it crashes immediately.

I ran a adb logcat to locate the error. I received a number of errors. They are the same errors received during my attempts to run the app in eclipse.

Do I need to go through an extra build process in order to get a complete app on the phone?

Any help or guidance would be greatly appreciated.

The logcat of errors follow:
