Unity Android build script for CI

This set of scripts can be used in CI systems (like Gitlab CI) to automatically build unity android projects and store the resulting APKs.

Usage

• Copy buildwindows.bat to your project root folder
• Copy buildproject.cs to Assets/_scritps/Editor (create the folder if necessary)
• Define the following environment variables (gitlab project settings -> variables):
  • ANDROID_KEYSTORE_NAME : Filename of the key store. For example yourcompany.keystore
  • ANDROID_KEYSTORE_PASSWORD : Password for the key store
  • ANDROID_KEYALIAS_NAME : Name of the key alias used to sign the application
  • ANDROID_KEYALIAS_PASSWORD : Password for the key alias
  • ANDROID_SDK_ROOT : Path to the android SDK on the build host
  • APK_OUTPUT_DIR : path where the APK should be saved, for example build\android (this will be generated relative to the project root on the ci runner)
  • APK_OUTPUT_FILE : name of the APK to be generated, for example myproject.apk
  • UNITY_EXE_PATH : full path to Unity.exe on the build host, for example C:\Program Files\Unity\Editor\Unity.exe
• Create your CI configuration ( .gitlab-ci.yml) like this example:
