My casual mobile game is already live on Google Play, built entirely in Unity, but Google now requires every submission to target at least Android API 36. I need the project migrated to that level (or higher) so the store stops flagging it each year. Scope of work • Open my existing Unity project, bump the Android SDK/Gradle settings and any plug-ins so the targetSdkVersion is 36+. • Make sure builds export cleanly as an AAB, ready to upload in the Play Console with no compliance warnings. • While you are inside the project, add a small set of new levels that follow the current mechanics and art style. No UI/UX redesign is necessary—menus and overlays can stay exactly as they are. Deliverables 1. Updated Unity project folder with all settings pointing to API 36+. 2. Signed release AAB that installs and runs on devices from Android 8.0 upward. 3. A short change log explaining the SDK changes and the new level locations in the hierarchy. That’s it—keep gameplay intact, leave the interface untouched, and get me a store-ready build that meets Google’s latest requirements.

I’ll first bring the Unity Android build to targetSdkVersion 36+ while preserving Android 8.0 support, then add the requested levels using the existing mechanics, prefabs, and art style without touching the menus or overlays. I’ll align the Unity Android plugin, Gradle templates, SDK/NDK/JDK settings, manifest, and dependencies so the project exports a clean signed release AAB. You’ll receive the updated Unity project, store-ready AAB, and a concise change log identifying the API changes and new level locations in the hierarchy within 2 days. Is the existing Android signing keystore available for producing the final release AAB? Muhammad Saad

hello, Bumping targetSdkVersion to 36 is the easy part, the real risk is the plugins, since ad, analytics, and billing SDKs built for older API levels are what break or crash once the target jumps, especially around newer permission and background rules. So I'd update Unity's Android settings and Gradle, then upgrade or replace each plugin to a version that supports 36, and test the build on real devices from Android 8 up so ads, purchases, and saves still work, not just compile. The new levels I'd build from your existing prefabs and mechanics so they match the current style exactly, then deliver the signed AAB and a change log listing the SDK changes and where each level sits. Which Unity version is the project on, since older versions may need an editor upgrade to support API 36? And which third-party SDKs are in it, ads, IAP, analytics? have a nice day.

Your Unity Android release needs an API 36 migration without disturbing existing gameplay or art style. The target is a clean signed AAB plus a few levels following the current game. I don’t have a published Unity game or live link to claim, so I won’t invent one. I can review the project, record Unity and package versions, update Android SDK/Gradle and target settings, then identify plug-ins blocking API 36. I’ll keep changes reversible, add levels by following existing scenes, prefabs, mechanics, and progression, and preserve current UI. I’ll test release builds on Android 8+ devices, check manifest behavior, verify install/launch/gameplay, and inspect Play Console warnings. Delivery includes the updated project, signed AAB using your signing setup, change log, and future update notes. My relevant real work includes Jyotish AI on Android/web and an AI website generation platform, backed by 9+ years; I won’t claim Unity experience. Which Unity version, Android plug-ins, and signing configuration are in the project, and how many new levels are required? My bid is $20 for 5 days of migration, level implementation, build testing, and handover. I can begin with a dependency audit.

Hi, Most likely the Play Console flags stem from plugins or Gradle settings still targeting an older Android API while embedded libraries declare a lower targetSdkVersion. I will prioritize eliminating those mismatches and any deprecated AndroidManifest entries that trigger compliance warnings. I have migrated multiple Unity projects to recent Android API targets, updated Android SDK and Gradle plugin versions, resolved plugin compatibility issues, and produced signed AABs accepted by Play Console. I will keep gameplay and UI identical while adding a small set of new levels that reuse existing prefabs, art assets, and scene structure to match the current mechanics and style. I will open your Unity project, bump targetSdkVersion to 36 or higher, update the Android Gradle Plugin and SDK versions, fix any plugin or manifest conflicts, build a signed release AAB that installs and runs on Android 8.0+, and add the new levels inside the existing hierarchy so menus remain untouched. - Do you have the release keystore and Play App signing details, or should I produce a signed AAB for you to upload? - What is the Unity Editor version and a short list of installed 3rd-party plugins so I can reproduce your environment locally? Happy to hop on a brief call whenever it suits you. @melopgabriel

Hi, I would start by opening your Unity project and bumping the Gradle and targetSdkVersion settings to API 36. Getting you a signed release AAB that targets API 36 and installs on Android 8 upward is the goal. I have handled builds where the SDK jump broke a plugin and the manifest needed work before the AAB passed review. I will add the new levels using your existing mechanics and art style, leaving menus and overlays untouched. I am determined to win this project and confident I can deliver high quality results within your deadline if awarded, and I will include a changelog covering the SDK changes and level locations.

Hi there, This is a straightforward migration for an experienced Unity dev — and exactly the kind of work my team handles regularly. Here's how I'd tackle it: API 36+ Migration I'll open your project and update the targetSdkVersion/compileSdkVersion, Android Gradle Plugin, and any outdated plugins or manifest entries that block API 36 compliance. I'll resolve dependency conflicts and deprecated APIs rather than just bumping numbers — that's where most migrations silently break. Clean AAB Build I'll configure a proper release keystore, verify the build exports as an AAB with zero Play Console warnings, and test install/runtime on Android 8.0 through current versions to confirm backward compatibility. New Levels I'll study your existing scene structure, prefabs, and level flow, then add new levels that reuse your current mechanics and art assets — no new systems, no UI changes, gameplay untouched. Deliverables: updated project folder, signed release AAB, and a changelog documenting every SDK change and where the new levels live in the hierarchy. You'll get a store-ready build and a developer who understands Unity's Android pipeline — not just a version bump. Ready to start today. Send over the repo or project zip, and I'll confirm the plugin situation before we begin.

Your Unity mobile game needs its Android target upgraded to API 36+ without disturbing the existing gameplay, UI, or live-game behavior, while also adding a small set of new levels and producing a clean release AAB. I have 3D game development experience and can work through the Unity Android build pipeline, including Android SDK/target configuration, Gradle settings, plugins/dependencies, release builds, and Android compatibility checks. I can first audit the existing project and identify any Unity version, plugin, manifest, or Gradle dependencies that could prevent an API 36+ build, then make the minimum required changes to preserve the current game. For the new levels, I can follow the existing mechanics, scene structure, prefabs, and visual style rather than introducing unnecessary changes to the UI or gameplay systems. I’ll test the resulting AAB on supported Android versions and verify that the updated project, signing configuration, and level hierarchy are ready for Play Console submission. Can you confirm the current Unity version and whether you already have the Android keystore used for the live Play Store build?

Hi, Ankit here. I understand you need your live Unity game bumped to Android API 36 or higher so it meets Google's submission rules, exported as a signed AAB ready for the Play Console, plus a small set of new levels in the existing style, with menus and UI untouched. What usually matters most here is that the API bump breaks plugins before it breaks the game, since SDK, Gradle, and third party Android libraries usually fail on first rebuild after the target change. A common issue in Unity API upgrades is that a plugin still targets the old SDK, so the build exports but crashes on launch, or the AAB passes Play Console but gets flagged for manifest requirements. The tricky part is updating the target while keeping gameplay and save data intact, since a careless upgrade can silently break progression for existing players. My approach would be to back up the project, bump target and compile SDK, update Gradle and any outdated plugins, test on Android 8 through current, then build the signed AAB and confirm no compliance warnings. New levels would follow the existing mechanics and art style, with clear notes in the change log. Can you confirm your Unity version and whether any custom Android plugins are already in the project? Looking forward to hearing from you.
