Overview
Updated project-wide dependencies to their latest versions and upgraded to Android Gradle Plugin (AGP) 9.1.0 and Gradle 9.4.1. This migration includes resolving compatibility issues with the latest build environments and preparing for the future Kotlin Multiplatform (KMP) recommended configurations.
Changes
1. Library and Tooling Updates
Upgraded major toolchains and libraries to their latest stable (including early adopter) versions.
2. AGP 9.0 Compatibility (gradle.properties)
Starting with AGP 9.0, the combination of the traditional
com.android.libraryandkotlin-multiplatformplugins is restricted. The following flags have been introduced to maintain the build:android.builtInKotlin=falseandroid.newDsl=falseNote: This is a temporary workaround. A long-term migration to the new KMP-specific Android plugin is planned.
Implementation Intent and Background
Why upgrade to Gradle 9 / AGP 9?
To leverage the new features of Kotlin 2.3 and AGP 9 (such as build performance improvements and new DSLs) and to ensure the project remains maintainable with modern standards.
Handling Platform-Specific DSLs (buildTypes, testOptions, packagingOptions)
The following design principles have been applied during this update:
buildTypes(debug/release setups) orpackagingOptions(duplicate file exclusion during APK generation) should be centralized in the final application (App module) side.com.android.kotlin.multiplatform.library) will not support many of these Android-specific DSLs. By removing or reducing reliance on them now, we aim for a simpler and more standard module structure.Verification
