This PR addresses multiple areas for improvement identified in the codebase, focusing on resolving TODOs, fixing bugs, and enhancing code quality.

πŸ”§ Fixed Critical Build Issue

The Android Gradle Plugin version was set to 8.12.0, which doesn't exist and prevented the project from building. This has been corrected to 8.4.0, a stable release.

File: gradle/libs.versions.toml

✨ Implemented Validation Error Mapping

Resolved the TODO comment in UserErrorMapper.kt for mapping validation errors from server responses. The implementation now properly parses server error data instead of always returning all validation errors.

Features:

  • Supports multiple server response formats: null, List<String>, and Map<*, *> with "errors" key
  • Handles both kebab-case (invalid-email-address) and SCREAMING_SNAKE_CASE (INVALID_EMAIL_ADDRESS) formats
  • Falls back to all errors if parsing fails (maintains backward compatibility)
  • Includes comprehensive documentation

File: data/src/main/java/com/hoc/flowmvi/data/mapper/UserErrorMapper.kt

Example:

// Server sends: {"error": "validation-failed", "data": ["invalid-email-address", "too-short-first-name"]}
// Result: NonEmptySet(INVALID_EMAIL_ADDRESS, TOO_SHORT_FIRST_NAME)

πŸ› Fixed Parcelable API Version Check

The parcelable extension functions were using > instead of >= for the TIRAMISU version check, causing the new API to not be used on Android 13 devices. This has been corrected.

File: core-ui/src/main/java/com/hoc/flowmvi/core_ui/parcelable.kt

Before:

if (Build.VERSION.SDK_INT > Build.VERSION_CODES.TIRAMISU) {

After:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {

πŸ”’ Implemented Production Logging Tree

Added a ReleaseTree implementation for Timber that only logs warnings and errors in production builds, preventing sensitive debug information from being logged in release builds.

File: app/src/main/java/com/hoc/flowmvi/initializer/TimberInitializer.kt

πŸ“ Code Quality Improvements

  • Simplified verbose navigator.run { navigateToAdd() } calls to navigator.navigateToAdd()
  • Replaced identity inequality operator (!==) with structural inequality (!=) for null checks (more idiomatic Kotlin)

Files: MainActivity.kt, SearchActivity.kt, SearchVM.kt

βœ… Enhanced Test Coverage

Added 5 comprehensive test cases for the new validation error mapping functionality, covering:

  • Null data handling
  • List of error strings
  • Map with "errors" key extraction
  • Invalid data fallback behavior
  • Mixed case error string normalization

File: data/src/test/java/com/hoc/flowmvi/data/mapper/UserErrorMapperTest.kt
