CGI-Player Launcher

System Requirements

This document mandates adherence to the Android Application Development Environment 
Setup Guide, as a prerequisite for system compliance.

By following these steps, you should have a consistent and well-configured development environment for your Android application on Windows 10/11. Remember to restart your system after making changes related to CMake in Android Studio and after updating Environment Variables.

Project Structure

CGI-Player Launcher is using the Android Gradle Plugin Version 3.5.3 with Gradle Version 5.4.1. The
Application is tested with ndk-26 that can be installed from the document in chapter Configuration and System Requirements. The supported API range is 23-28. The supported ABIs are arm64-v8a, x86_64, x86. The CGI-Player Launcher Android Application is using the NativeView library included in the Android Application. This NativeView Library is moved out of the project directory and will be included from outside of the project as library.

Building and Running the Android Application

To be able to build and run the Android Application, the following steps must be done.

  1. Subst [windows-commands/subst] the root of CGI Studio.
    • Open a Command Prompt in the root of CGI Studio directory e.g., “...\cgistudio” and type: “subst
      x: .” and click enter. The CGI root is now available under the subst "x" drive in Windows Explorer.
  2. Open the Android Application in Android Studio from “X:\cgi_studio_apps\References\Android\AndroidCgiPlayerLauncher”.
  3. Open the “local.properties.sample” file and change the “USERNAME” in the SDK and NDK path to match the
    system it will be used on. Also the path to the asset and ABI can be set here. This ABI should match the target CPU architecture.

  1. Copy the contents of the "local.properties.sample" to “local.properties”. Note that if the SDK or NDK paths do not exist, Android Studio will reset the “local.properties” again after trying to Sync Project with Gradle Files.
  2. Make sure the JDK is set to 11 in [File | Settings | Build, Execution, Deployment | Build Tools | Gradle]
    like described in chapter Java Development Kit (JDK).
  3. Create an asset with CGI Studio for Android by running “X:\bin\SceneComposer\SceneComposer_Android_OpenGLES30.bat” and choosing e.g., “3D Basic” and save this as Test.bin into the /sdcard/ directory of the target/emulator. For the emulator this can be done in the "Device Explorer" of the emulator in Android Studio.
  4. Run the Application by selecting the target/emulator and clicking on “run sample”.
  5. The first time the Application starts, it will request permissions. Click accept.
  6. After choosing the desired asset in the list, the solution should be running.

Troubleshooting

  • If encountering any issues during the setup, refer to the official documentation for Android Studio,
    CMake, and NDK for troubleshooting steps.
  • If you encounter any issues linked to outdated source code, reach out to the Android developers for
    assistance in implementing a resolution.
  • Check for updates regularly and keep your development environment components up to date.
