    Hello everyone, I encountered errors when compiling the Android application. I'll leave them below. I tried to run unity as an administrator, deleted Mobile Notification - it didn't help

    Code (CSharp):
    1. Exception while marshalling C:\Program Files\Unity\Hub\Editor\2022.3.7f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\build-tools\32.0.0\package.xml. Probably the SDK is read-only
    2. Exception while marshalling C:\Program Files\Unity\Hub\Editor\2022.3.7f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\platform-tools\package.xml. Probably the SDK is read-only
    3. Exception while marshalling C:\Program Files\Unity\Hub\Editor\2022.3.7f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\platforms\android-31\package.xml. Probably the SDK is read-only

    How to troubleshoot build failures:

    Obviously, if there is actionable data within the errors, fix those problems. Each error entry may have more information than can fit in the console log so select each error and read the expanded view below it.

    If that gives you nothing worthwhile (look to Google! You're never the first one!), then...

    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 (edited on August 23, 2023 to include Android SDK 33...):

    Try #1 listed here and share if #1 or #2 worked.
    Try once right-clicking the SDK folder and give permissions to all (Properties -> Security tab)
