Eclipse application package renaming tool give an error

Question

I am trying rename my application package using eclipse Android Tools. It is working in other projects but unfortunately not in my project. :(.

It gives me Internal error "java.lang.reflect.InvocationTargetException". Please find end of thread for full error.

In project, I have several library projects inculcated (like SlidingMenu, ABS, PullToRefresh, google-play-services_lib). Also have jars like gson, Jakson, twitter 4J and other. Also i have around 35 packages for different modules.

I don't know what causes this problem. I have tried many things but haven't got any solution yet.

Please help me. Thanks in advance. :)

Here is full detailed Error:

Answer 1

The Problem seems to be have multiple problem but it shows one kind of error.

Please check for the unused code in your application i.e unused inner class, unused public class if you found that, remove that and try to clean the project and rename it.

If there are errors in the XML files then also this kind of problems may happen. you need to check on that too.

All the best.
