All- I have an app that works fine on my actual device (Android 4.0.4) and on most of my emulators (2.3.3, 3.0, 3.1, 3.2, 4.0, 4.0.3, etc.). When I try to change from activity A to activity B via an onClick method, on my 2.2 emulator it force closes. I am getting this in the logcat:

I did a little research and found out that the cause of java.lang.VerifyError is because of a lack of features that are not support in that API (ie. using NFC in android 1.6), or using an non-compatible external library. I am not using an external library so I figured I must be using advanced features that are only available in android 2.3.3+. I went to the problem lines, ie 1429, and found this spinner1.getSelectedItem().toString();. I than went to the android website and found that this method has existed since API 1. Other features app has include:
spinners, buttons, 4 activities, edittext, textview, and a menu. QUESTION: What could be causing java.lang.VerifyError other than non-compatible external libraries and android features? I will post code from specific lines as you ask for them. Thanks for your time!
