npx init with "--package-name" makes Android application crash on runtime

[jvaronenka]

Description

If you initialise an application with "npx init" and provide a package name with "--package-name", then the built Android app will crash on startup.

No such issue exists on iOS.
No such issue on 0.72 versions.

I have narrowed this down to how MainActivity.kt is generated. It generates the following function:

override fun getMainComponentName(): String = "com.mycompany.MyApp"

However, it should be:

override fun getMainComponentName(): String = "MyApp"

Manually changing that function and rebuilding resolves the issue.

Steps to reproduce

1. npx [email protected] init MyApp --version 0.73.2 --package-name com.mycompany.MyApp
2. cd MyApp/android
3. ./gradlew assembleRelease
4. Launch app/build/outputs/apk/release/app-release.apk

I can't add a reproducer, but I have added reproduction steps. Is that sufficient?
