Steps to Reproduce

flutter run -v

Thank you. I've got this after changing my package name from com.yourcompany.appname to something better on android/app/src/main/AndroidManifest.xml, but I didn't know there were a lot of other places I should have updated to match the new name, including the directory tree (because there is some android/app/src/main/java/com/yourcompany/ directory that must be changed).

Running a find . -name "yourcompany" and an ag "yourcompany" should help.

False alarm. The structure of the project changed and I copy pasted the android files from flutter create without updating the MainActivity package name.

You need to check your app level build file under ndk. It should contain all types supported platforms incase the device you are trying to run on isn't on the list. Update your ndk under app level like this:
