Question
What does the build error 'unrecognized Attribute name MODULE' mean in my Android project and how can I resolve it?
Answer
The error 'unrecognized Attribute name MODULE' typically occurs in Android projects when using Kotlin's annotation processing (Kapt) after an upgrade to a new Android version, such as Android 12. This issue is often related to incompatibilities between library versions, Gradle tools, or deprecated annotations in the code.
// Example of updating the Kotlin version in build.gradle
android {
// Previous configurations
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:<latest_version>"
// Other dependencies
}
Causes
- Incompatible Kotlin version with the Gradle or Android plugin version.
- Outdated dependencies that may not support the new Android version.
- Incorrect usage of annotations that may have changed or been deprecated in newer Kotlin or Android versions.
Solutions
- Update the Kotlin version in your `build.gradle` file to the latest stable release.
- Ensure that all dependencies, especially annotation processors, are updated to versions compatible with Android 12.
- Check your `build.gradle` for any outdated or incorrect configurations related to Kotlin annotation processing (Kapt).
- Clean your project using `./gradlew clean` and then rebuild to clear any cached states.
Common Mistakes
Mistake: Not updating libraries when upgrading Android version.
Solution: Always update your libraries when moving to a new Android version to prevent compatibility issues.
Mistake: Failing to clean the project after making changes.
Solution: Run `./gradlew clean` before rebuilding to ensure no cached data is causing problems.
Mistake: Using deprecated annotations in your code.
Solution: Update your code to use the latest annotations supported by the current Kotlin and Android versions.
