Activity Class {[package name]/[package name].MainActivity} Does Not Exist

db-flutterwave commented 1 year ago

Description

I initialised a fresh React Native app on my Intel mac and tried running the react-native run-android command and the app builds but fails to start on my emulator with the following error.

Starting: Intent { cmp=com.testproject/.MainActivity }
Error type 3
Error: Activity class {com.testproject/com.testproject.MainActivity} does not exist.

The emulator runs Android 12.
I also tried on my physical android devices running android twelve.
I was able to run a fresh React Native project running version 0.70.8 successfully and it worked fine. Please how can I resolve this issue as I want to upgrade our app running 0.64.4 and would like to upgrade to 0.71.6 but this error currently serves as a hinderance.

Note: My issue is not how to upgrade but rather how to resolve the launch bug for development so I can run my app in development.

React Native Version

0.71.6

Steps to reproduce

Start a fresh react native project on a Macbook (maybe running intel as mine is running on intel).
Try running react-native run-android on the newly initialised project.

Thanks for sending a repro. I've just tested on a physical device running Android 13, and all works fine without any problems

Thanks @cortinico, this is quite strange, I just ran it again after seeing your message and it worked, possibly something was failing on my machine relating to Gradle that I didn't get an error for, will close for now and investigate, if I find anything I'll run some more tests and report back. Thanks.

@Tavernari I was facing the same issue, https://github.com/facebook/react-native/issues/36995 fixed it for me.
