애플리케이션용 메인 APK 확장 파일을 생성하려면 Unity에 애플리케이션을 분할하도록 지정합니다. 애플리케이션을 분할하는 방법에 대한 자세한 내용은 애플리케이션 바이너리 분할을 참조하십시오.
Now when you Build the application, Unity generates the APK and the main APK expansion file then copies them both to the output directory. Unity uses the name of the application followed by .main for the name of the APK expansion file. For example, if the application is called my-app, the APK will be my-app.apk and the APK expansion file will be my-app.main.obb.
If the application starts and it can’t find and load the main APK expansion file, only the first Scene is available. In this case, you should attempt to download the APK expansion file. For more information, see Download process.
