Android Runtime Verify Error

Question

My intention is to read a raw resource and convert it to Java code using JSON. The class and external libraries that do this are stored in a different project. When I run my app I get this error in the log cat:

I can tell that the error is arising from the creation of a JSONArray. I have come across this error already on stackoverflow but there was no clear way of how resolve this. Can anyone recommend to me a way to solve this problem. Help would be greatly appreciated.

Answer 1

You are adding the net.sf.json library that seems to have a unresolved dependency. Try to use the Android SDK JSON implementaton instead.
