I have a Android project who's package name is kind of like this com.example.MyPackage where as MyPackage has two capital letters M and P, Due to them i am not able to use data binding.

When i add data binding and build my project it says not able to guess the name. I found out on stackover flow there are people discussing that it is because you have capital case letters inside package name.

You can change the package name of your code, just don't change/update the application_id from build.gradle file

PlayStore uses application_id from app-level build.gradle file as identifier

  • Your answer is correct but will i be able to use data binding by changing package name? – syed muhammad awais Feb 08 '20 at 11:43
  • [kapt] An exception occurred: java.lang.IllegalArgumentException: couldn't make a guess for com.example.MyPackage.databinding.ActivityLoginBindingSw600dpImpl this is the issue i get even after changing the package name to com.example.mypackage it still gives this error – syed muhammad awais Feb 10 '20 at 05:55
  • `com.example.MyPackage` ? if you change the package name to `com.example.mypackage`, then it should have automatically changed databinding variables. Try to clean and rebuild the project. also make sure you aren't mixing source **package name** with **application_id** – Harsh Jatinder Feb 10 '20 at 07:15

    Yes it is working great now.Issue is that i had to change the package name in manifest as well. Due to some reason refactor process didn't work to change the package name in manifest as well, So i had to change it in the manifest and after that invalidate cache and restart the android studio made it work perfectly ! – syed muhammad awais Feb 10 '20 at 07:35
