ANDROID_TARGET_SDK_VERSION environment variable is missing

[ygrinevich]

It seems that ANDROID_TARGET_SDK_VERSION env variable is missing here

unity-builder/src/model/image-environment-factory.ts

Line 49 in 36891ec

{ name: 'ANDROID_SDK_MANAGER_PARAMETERS', value: parameters.androidSdkManagerParameters },

As a result androidTargetSdkVersion command line argument will always be empty, see

unity-builder/dist/platforms/ubuntu/steps/build.sh

Line 143 in 36891ec

-androidTargetSdkVersion "$ANDROID_TARGET_SDK_VERSION" \

Good catch.
