Resolving Build Failure Error in React Native 0.72-rc6 for Android Release

When working with React Native, developers often encounter issues that can disrupt the build process. One such challenge arises when creating release builds for Android using React Native 0.72-rc6. Specifically, many experience a build failure error related to the task :app:lintVitalAnalyzeRelease. This post addresses the underlying issue and presents a systematic solution to fix it efficiently.

Understanding the Problem

The error message you're seeing indicates that there is a dependency issue with the Android build configuration. In essence, the build system detected that the task :app:lintVitalAnalyzeRelease is relying on the output of another task, :app:copyReactNativeVectorIconFonts, without an explicit declaration of that dependency. Failing to declare this dependency can lead to unpredictable results, especially during the complex build process.

What Leads to This Issue?

The problem is commonly attributed to the react-native-vector-icons library, which works seamlessly in debug mode but causes issues during the creation of release APK or bundles. Without proper handling of task dependencies, the build fails and prevents you from proceeding to deployment.

Solution: Creating a Patch for React Native Vector Icons

To resolve the build failure error, you'll need to create a patch for the react-native-vector-icons. The goal is to ensure that the relevant tasks are properly linked. Here's how to approach this solution systematically:

Step 1: Modify the Fonts.gradle File

Locate the fonts.gradle file in the react-native-vector-icons directory within your project's node_modules. You'll need to make some adjustments to the code to explicitly declare task dependencies.

Open the fonts.gradle file located at:

Add the following code to ensure that the relevant tasks depend on one another:

Save the changes to the fonts.gradle file.

Step 2: Rebuild Your Project

After making the changes, it's important to rebuild your project. You can do this by running the following command in your project directory:

This process cleans the current build and assembles a new release version of your app, incorporating your recent changes to resolve the dependency issue.

Conclusion

Encountering build errors while developing with React Native, especially when moving from debug to release mode, is a common issue. By following the outlined steps to create a patch for react-native-vector-icons, you can effectively resolve the configuration problem that leads to build failures. This solution not only resolves your current issue but also ensures smoother builds in the future.

By understanding the importance of task dependencies in Gradle, you'll be better equipped to handle similar challenges in your React Native development journey. Happy coding!
