Unable to instantiate application - Unable to get package info

Question

I have unexpectedly received the following error, Unable to instantiate application, while trying to run my application. I have included the log cat below. I feel that the package name is not in line with the package name, and hence that could potentially be the error.

Answer 1

Simply uninstall app and then run again, It happens when dalvik reinstalls .apk file and tries to reuse previous activities from same package
