Job ID: 35144330

Budget: $50 – $200 USD

You will need to update an old Unity game for Android and upload the game by yourself to Google Play. It will be a mostly be a simple update of updating some SDKs and fixing crashes.



1) Must have Unity Plus/Pro.
I will invite your account to my organization so you can link the project correctly to enable analytics and other services properly.

2) Update Unity services packages.
We are getting this warning in Google Play dashboard:
https://forum.unity.com/threads/your-app-includes-non-compliant-sdk-version.1302498/
This app does not use Unity Ads package as it uses Admob but we are still getting this error. I suspect we need to update the "Unity Ads" and other Unity services to the latest versions such as "Unity Analytics" and "Unity IAP". You need to update those packages.

3) Target API level 31 for Android.
Currently it is targeting API level 29. Change it to target API 31. You will need to make it build to AAB correctly and fix any errors.

4) Fix crashes, ANR and errors.
Currently, in Google Play dashboard, the crash rate and ANR is very high and rising. Most of the crashes are coming from Android 12. You will need to test it properly on Android 12 and fix all crashes and errors. There is not much information as the info shown is “libunity, java.lang.Error” on Google Dashboard. I suspect some old SDKs are not working with Android 12 such as Firebase. We either need to remove or update it. Also, fix any potential crashes and errors with Android 12.

5) Update Admob plugin for Unity.
Update Admob plugin for Unity to the latest one: https://developers.google.com/admob/unity/quick-start

6) Google Play billing library updated to version 4.
We are still using old version and this needs to be updated to version 4.

7) Upload AAB build to Google Play by yourself.
You will be invited to Google Dashboard as a developer and you will need to upload the AAB build by yourself.

8) Feel free to update any Unity packages if it does not break the game and if you need to fix some crashes or errors.

9) Provide the final Unity source code with all changes upon completion.

10) Final payment will only be released after Google has reviewed and published the game live successfully. If there are any errors upon publishing, you will need to fix it so that it can be published live successfully.
