java.lang.IllegalAccessError class ref in preverified class resolved to unexpected implementation

Question

Im getting an "java.lang.IllegalAccessError class ref in preverified class resolved to unexpected implementation" error when I push a button that starts a method in MainActivity which is supposed to start a new Activity. What can I do to fix this? This is my first attempt to make an android application, so ill need step by step instructions :)

Also I havent been able to test if it works yet, but if you notice anything wrong with my AugiActivity service implementation or the local broadcast implementation feel free to let me know.

Thanks!

fyi: MainActivity starts Navigation Activity, which starts Service AugiActivity

Augi activity sends local broadcast messages to Navigation

Answer 1

In my case I changed project setting in Intelij Idea. Go to modules -> dependencies, then set scope of the lib to 'Provided'.

Answer 2

in Open Module Settings->dependencies

setting the scope for the line

{include=[*.jar], dir=libs}

to provided

worked for me

Answer 3

I solved it. Seems like including the maps.jar file in the libs folder was a bad idea. removing it corrected the problem. Thanks all.
