    Hello friends

    I am facing an issue with drive 2022.2.1F1. I'm trying to update my game project to submit it to the play store, but in the process of building il2cpp I get errors that I still can't resolve... Can anyone help me? please

    Kind of looks like you're trying to include some iOS-only code in your android build? Those first two errors are complaining about _iOSStepCounterIsAvailable being undefined, and maybe the other errors are just following on because of that. Are you trying to reference _iOSStepCounterIsAvailable, but it's defined within an #if conditional that's not included in your android build?

    Is _iOSStepCounterIsAvailable actually from your code, or a library you're including?

    How to troubleshoot build failures:

    First, make a blank project with a single blank scene and prove that it builds successfully.

    If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.

    Until you can build a blank project to the target platform, don't fiddle with anything else.

    Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.

    Most often things that prevent building are third-party libraries such as Firebase.

    Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.

    It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.

    Android build not building:

    Recently (circa July 2022) there have been reports of Unity's installer failing to install the Android Tools.

    Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022:
