Weird and Unsolvable Exception

Android
1

Hi. While developing an app on Android Studio ( Meerkat Feature Drop | 2024.3.2 Patch 1 ), everything was going fine till today morning when, in order to create a ViewModel and Relevant Factory, I created a class called DataFetchViewModel. And suddenly following error has started to come. I have tried every single possible solution right from clearing caches, updating Android Studio, Repairing IDE, Rescanning indexes and what not. Any Help would be really helpful :

kotlin version: 2.0.21

I am not posting the actual DataFetchViewModel file as it neither has any runtime or compile-time errors.

Any help to resolve this issue is really helpful.

Are you using a build tool for this, like Maven or Gradle? If so, what happens if you try to compile using your build tool via the command line, completely outside Android Studio?

Assuming Android Studio has an .idea folder, the same as IntelliJ, have you tried deleting that folder and re-importing your project to Android Studio?

3

Yes. I have tried the second option of deleting the build artifacts. But unfortunately that did not work. But when I build it using gradlew, it builds fine. But when I run the project in Android Studio, it fails again with the same exception

Interesting, so the problem is definitely unique to Android Studio.

I guess the question is whether it can be reproduced. Do you have a different computer that you could put Android Studio on and load up your project?

I think ultimately you have to figure out whether this is a bug in Android Studio, or something weird about Android Studio on your computer. If it’s a bug, report it to Jetbrains. If it’s just your computer… uninstall and reinstall Android Studio, maybe.
