### WPAndroid Integration Configuration

Source: https://github.com/wordpress-mobile/gutenberg-mobile/blob/trunk/WPAndroid Integration.md

This section details how WordPress Android integrates with Gutenberg Mobile, specifically focusing on the `react-native-bridge` dependency and the mechanism for substituting binary dependencies with local source code during development.

```APIDOC
Project: WordPress Android Integration

Dependency Management:
  - WPAndroid integrates `react-native-bridge` as a binary dependency fetched from a remote Maven repository.
  - CI pipelines in the Gutenberg Mobile repository deploy new versions upon commits to `trunk`, open PRs, or tag creation.

Local Development Setup:
  - To use a local checkout of `gutenberg-mobile` for development:
    1. Copy `local-builds.gradle-example` to `local-builds.gradle` in the WordPress-Android project.
    2. Update the `localGutenbergMobilePath` variable in `local-builds.gradle` to point to your local `gutenberg-mobile` directory.
    3. Ensure the Metro server is running (`npm run start:reset` in `gutenberg-mobile`).
  - This setup uses Gradle's dependency substitution to build `react-native-bridge` and other sublibraries from the local folder instead of the binary dependency.

Configuration Properties:
  - `ext.gutenbergMobileVersion`: Property in `WordPress-Android/build.gradle` that specifies the version of the `react-native-bridge` binary dependency.
  - `localGutenbergMobilePath`: Variable in `local-builds.gradle` that specifies the path to the local `gutenberg-mobile` checkout for development.

Build Process:
  - CI deploys versions using:
    - `npm ci`
    - `npm run bundle:android`
    - `gutenberg/packages/react-native-bridge/android/publish-aztec-and-bridge.sh <version>`
  - WPAndroid's build process can be configured to use either the binary version (by setting `ext.gutenbergMobileVersion`) or the local checkout (by configuring `local-builds.gradle`).

Testing PRs:
  - To test a Gutenberg Mobile PR in WPAndroid:
    1. Set up WPAndroid for local checkout (as described above).
    2. Switch your `gutenberg-mobile` checkout to the desired PR branch.
    3. Run the WordPress-Android application.
```
