Android Studio: ClassNotFoundException

Question

i was busy with my app for over a week, when suddenly:

11-12 07:59:17.860    1653-1653/nl.test.myapp E/AndroidRuntime﹕ FATAL EXCEPTION: main
java.lang.Runtim         


        

Answer 1

This happened to me too, and none of the postings here helped. My problem was also caused by my having renamed the root package. My ClassNotFoundException was showing a DexPathList which was the old path to my package. I found the cause was in my Gradle Script called "build.gradle (Module: app)" I had a line saying: applicationId "old package name". I changed this to the new package name, did a gradle sync, and everything worked.
