Show / explain how you changed the PackageName.

There are a number of places you need to change the package name for the compilation to work correctly. In particular, my guess is that you didn’t change the output package name for the Kawa compilation step, so when the screen is compiled down to bytecode it’s put in the old package name, not the new one, and therefore isn’t found when you attempt to launch the app. You can confirm this by using dex2jar to decompile your APK file and inspect the resulting JAR’s contents.


Can you explain little bit more how we can do this , some steps and hint too ?

I have added custom package name according to this https://groups.google.com/forum/m/#!searchin/app-inventor-open-source-dev/Custom$20Package/app-inventor-open-source-dev/vzQXwVwmj4I and done all things , and it works too (means package name gets changed according to user and package name is also changed in AndroidMaifest.xml) but the issue comes when i open app and see above error . I don’t have idea how to solve this .
So how i can resolve this issue ?
