Description

I am working on a brownfield integration. When package attribute is not set in AndroidManifest.xml (it's deprecated from AGP 7.3) it takes the namespace value from the module-level build.gradle. However, it cannot access it when the module is named differently than app. In my case, the file is under mastodon/build.gradle, and CLI looking specifically for app/build.gradle.

This leads to an error:

error Failed to build the app: No package name found. We couldn't parse the namespace from neither your build.gradle[.kts] file at null nor your package in the AndroidManifest at /Users/tomaszmisiukiewicz/Documents/projects/mastodon-brownfield/android/mastodon/src/main/AndroidManifest.xml.

Reproducible Demo

1. Clone https://github.com/TMisiukiewicz/mastodon-brownfield, checkout v-0.76 branch and install packages
2. Open AndroidManifest.xml and remove package attribute
3. Run ./node_modules/@react-native-community/cli/build/bin.js config
