android - Java.lang.verifyerror how do I fix or even find out the root cause?

Question

Currently going through a nightmare attempting to fix a java.lang.verifyerror, was having issues with eclipse so I decided to uninstall and reinstall it, everything seemed normal until I tried to launch the app, thats when I noticed that I couldnt launch the app anymore, everytime I try to lauch it it crashes and gives me this error, however I have no clue what is causing it as the error log gives me little clues and I cant find any concrete answers on the internet, can anyone tell me what is wrong based on my logcat? any help will go a long way thanks

This is a problem with ADT v22. It is pretty hard to fix. There are some suggestions here: The CommonsBlog - Don't Manually Modify Your Eclipse Build Path... Except Now for R22 (thanks to StreetsOfBoston and CommonswareGuy)
