Summary of Changes

Hello @HakimHauston, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves build errors and ensures the project's compatibility with Android Studio 4.x and newer development tools. It achieves this by updating core Android SDK versions, upgrading Gradle build tools, migrating to the latest Play Asset Delivery library APIs, and streamlining dependency management to use standard Maven repositories.

Highlights

• Android SDK Version Updates: The compileSdkVersion has been upgraded to 34 and minSdkVersion to 21 in the Teapot sample, aligning with modern Android development standards.
• Gradle Tooling Updates: The Android Gradle Plugin has been updated from 4.0.0-beta03 to 4.0.2, and the Gradle distribution URL now points to gradle-6.2.2-all.zip, ensuring compatibility with newer build environments.
• Play Asset Delivery API Migration: The native C++ code in PlayAssetDeliveryUtil.cpp has been updated to use the new AssetPackManager_showConfirmationDialog API, replacing the deprecated showCellularDataConfirmation.
• Dependency Management Refinement: The project now uses Maven-based dependencies for Play Asset Delivery (asset-delivery:2.3.0 and asset-delivery-ktx:2.3.0), removing reliance on local play-core-native-sdk and playcore.aar files.
• Java 8 Compatibility: Explicit compileOptions for JavaVersion.VERSION_1_8 have been added to the Teapot sample's build.gradle.

Code Review

This pull request updates various build configurations and dependencies to fix build errors, likely for compatibility with newer Android development tools. The changes include updating the Gradle plugin version, compile SDK version, and switching from a local Play Core Native SDK AAR to a Maven dependency. My review includes suggestions to update the target SDK version to meet Play Store requirements, remove an unnecessary Kotlin dependency, align a C++ function name with the new API it uses, and replace the deprecated jcenter() repository.

[gemini-code-assist]

While it's great that you've updated compileSdkVersion to 34, the targetSdkVersion is still set to 28 (on line 29). This is very outdated and does not meet current Google Play requirements, which mandate targeting a recent API level (e.g., 33 or higher). To ensure your app is compliant and can leverage the latest platform improvements, you should also update targetSdkVersion to 34 to match compileSdkVersion.

While updating the Android Gradle Plugin, it's a critical time to also address the use of jcenter() (line 21). JCenter has been sunset and is no longer a reliable repository, which can lead to build failures. Please replace jcenter() with mavenCentral() in both the buildscript and allprojects repository blocks to ensure future build stability.

This dependency adds the Kotlin extensions library for Play Asset Delivery. However, this project doesn't appear to use Kotlin (e.g., TeapotNativeActivity.java is a Java file, and the kotlin-android plugin isn't applied). To keep the app lightweight and avoid unused dependencies, it's recommended to remove this line.

The API calls here have been updated from ...showCellularDataConfirmation... to the more generic ...showConfirmationDialog.... However, the enclosing function is still named ShowCellularDataConfirmation (line 224), and the log message on line 232 also uses this old name. This creates a mismatch and can be confusing. For better code clarity and maintainability, consider renaming the function to ShowConfirmationDialog and updating the log message accordingly. This would also require updating the function declaration in PlayAssetDeliveryUtil.h and any call sites.
