Okay, here's some HTML formatted text explaining why Lombok might not be working in your Android project, targeting roughly 500 words. ```html

Lombok, a popular Java library that reduces boilerplate code, can sometimes be tricky to set up correctly in Android projects. When Lombok doesn't work as expected, you might find yourself still writing getter/setter methods, constructors, and other repetitive code, defeating Lombok's purpose. Here's a breakdown of common reasons why Lombok might fail in an Android environment and how to troubleshoot them.

Dependency Issues

First and foremost, ensure Lombok is properly added as a dependency to your project. This isn't a simple matter of just adding it to your build.gradle file. Lombok requires annotation processing, which has specific implementation requirements in Gradle.

You need to include Lombok as both a compile-time and runtime dependency. In your app's build.gradle file (app/build.gradle), add the following:

dependencies {
    compileOnly 'org.projectlombok:lombok:1.18.30'
    annotationProcessor 'org.projectlombok:lombok:1.18.30'
}

The compileOnly dependency ensures that Lombok is present during compilation but isn't packaged with your APK, reducing its size. The annotationProcessor tells the Gradle build system to use Lombok to process annotations during the compilation phase. The version number might need to be updated to the latest stable version.

IDE Integration Problems

Even with the correct dependencies, your IDE (Android Studio) needs to be configured to properly recognize and process Lombok annotations. Android Studio sometimes lags in automatically detecting annotation processors.

To fix this, ensure that annotation processing is enabled within Android Studio's settings. Go to File > Settings > Build, Execution, Deployment > Compiler > Annotation Processors and check the box labeled "Enable annotation processing". If this setting was already enabled, try toggling it off and then back on, followed by a clean and rebuild of your project (Build > Clean Project and Build > Rebuild Project).

Sometimes, the IDE's cache can become corrupted, leading to issues with Lombok. Try invalidating the cache and restarting Android Studio. Go to File > Invalidate Caches / Restart... and choose "Invalidate and Restart".

Plugin Conflicts

Occasionally, other Gradle plugins can conflict with Lombok's annotation processing. If you're using other annotation processors (e.g., Dagger, ButterKnife), ensure their configurations are compatible with Lombok. The order in which annotation processors are executed can sometimes matter, so try adjusting the order in your build.gradle if applicable.

Project Structure Issues

Ensure your project structure is correct and that your source code is in the correct source directories (e.g., src/main/java). Incorrect project structure can prevent Lombok from correctly finding and processing your classes.

Kotlin Compatibility

If you're using Kotlin in your Android project, Lombok may require additional configuration. Lombok is primarily designed for Java, and while it can work with Kotlin, you might encounter issues related to Kotlin's null safety features or other language-specific aspects. Consider using Kotlin's data classes and other features that provide similar boilerplate reduction if integration proves problematic.

Version Mismatches

Ensure that the Lombok version you're using is compatible with your Gradle version and Android Gradle Plugin version. Incompatibility can lead to unexpected errors or Lombok failing to process annotations correctly. Check the Lombok website or related documentation for compatibility guidelines.

By systematically checking these common causes, you should be able to diagnose and resolve why Lombok isn't working in your Android project and begin enjoying the benefits of reduced boilerplate code.
