My existing mobile game is sitting in Unity 2021.x and still compiles only against Android API 33. I need it lifted to the most recent long-term-support Unity release that lets me target Android API 36 without a single editor error or build failure (now project build with API36 unity 6.2 , however the apk do not get install). The project relies on a handful of third-party plugins; most are just a version or two behind, so I also need those updated to the newest compatible releases and re-linked where necessary. No custom engine work is involved—just a clean migration, plugin updates, Gradle settings, and a proof that an .aab can be produced. You’ll receive the full repo (Git) and the current list of plugins the moment we start. I’m under time pressure, which is why I’m handing this off. Acceptance criteria • Project opens in the upgraded Unity editor with zero console errors or warnings. • Android build system targets API 36, completes successfully, and outputs a signed .aab. • All third-party plugins compile and function as before (ads, analytics, IAP). • Clear change log or commit history so I can see what was touched. * Explain what was the fix , since the original full project code can not be shared , so that the same fix is intended to be implemented based on this one change fix . ( It is small 2D project and the android build pass however the produced apk doesn't install successfully) The project would be shared through git hub ( I will grant access to private GitHub code , and will check the work from my side by that )

Hii, the failed install usually comes from plugin or Gradle conflicts with API 36. I will update the project to the latest Unity LTS, bring all plugins to compatible versions, clean the build settings, and make sure you get a working .aab that installs fine. I’ve handled similar migrations before, and I’ll also give you a clear changelog so you can see exactly what was fixed and reuse the same solution elsewhere. Once done, your repo will open error-free and build smoothly against API 36. Regards, Usama

Hey there, Quick question: when the APK fails to install, do you get a logcat error pointing to signing, ABI mismatch, or manifest conflicts? Also, do you want the final deliverable to include both a working APK and a signed .aab ready for Play Store submission? I’ve upgraded several Unity projects from 2020/2021.x to LTS releases while keeping plugins fully functional. The main challenges usually involve Gradle and AndroidManifest updates, plugin version compatibility, and signing configuration, these are often why APKs fail to install even when the build completes. I focus on: Clean Unity upgrade with zero console errors Updating all plugins to their latest compatible versions and relinking them Gradle & manifest configuration to target API 36 and produce a signed .aab that installs correctly Clear changelog of every modification with explanations so you can replicate fixes in other repos This approach ensures a stable, production-ready build while preserving all existing ads, analytics, and IAP functionality. Looking forward to discussing more on chat. Best, Kirill
