Unity Build Failure, unable to update SDK

So, building on Android, I get the error; “Unity Build Failure, unable to update SDK”. The project I’m working on has been updated to a new SDK but Unity doesn’t have that SDK version installed

I used the SDK manager to update to the correct API but Unity didn’t see the change as Unity is looking at it’s ‘local’ version.

To solve this, you need to install to the specific Unity version that you’re using. Simple process; Open a CommandLine (CMD) as Administrator and type: –

“C:\Program Files\Unity\Hub\Editor\2019.3.11f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\tools\bin\sdkmanager.bat” “platforms;android-29”

Obviously, you’ll need to adjust the Unity version and the Android SDK to what you need, but this does an in-place update of the Unity installed SDK.

Once you run that, Unity is happy again
