This error can halt your progress, leaving you confused about how to rectify the situation. In this guide, we'll break down what this error means and how you can fix it swiftly.

This issue often points to a specific part of your build.gradle:app file where the android {} block is defined. Let's look at an example of what might be causing the problem.

Identifying the Error in Your Code

In your original build.gradle:app file, you may have structured your code like this:

Problematic Structure

The placement of the defaultConfig block within buildFeatures is incorrect. The defaultConfig should always reside directly within the android {} block, as it defines application-level settings.

How to Fix the Issue

To resolve the error, you need to refactor your build.gradle:app file. Follow this structure:

Key Changes Made:

Moved defaultConfig: This block was moved out of the buildFeatures and placed directly inside the android {} block.

Removed Unnecessary Clause: The buildReleases clause was removed since it isn’t necessary when you already enable viewBinding in buildFeatures.

Conclusion

Encountering the No signature of method error in Android Studio can be a stumbling block, but it’s often straightforward to fix with a little refactoring in your build.gradle:app file. By ensuring that all configuration blocks are placed correctly, you'll have your Kotlin application up and running without further issues.

Now that you have a clear understanding of how to tackle this error, you're well-equipped to continue your Android development journey without frustrations. Happy coding!
