NativeViewLibrary

Requirements 
 This document mandates adherence to the Android Application Development Environment Setup Guide , as a prerequisite for system compliance. 
 
 The project requirements  
 
 NativeViewLibrary Android application uses the  Android Gradle Plugin version 7.2.1 and Gradle version 7.3.3 . 
 A custom NDK 26  is required, as described in the Android Native Development Kit (NDK) chapter.  
 CMake 3.22.1 is required as described in the  CMake chapter. 
 Eclipse Temurin JDK 11 is required as described in Java Development Kit (JDK) chapter. 
 Supported API levels: 23–28  (The application is compatible with later Android versions up to API 36 on Android 16). 
 Supported ABIs:  arm64-v8a, x86_64, x86 
 The NativeViewLibrary Android application integrates the NativeView library, which is provided externally from ../libs/nativeview-lib and already imported into the project. 
 
 
 Building and Running the Android Application 
 To build and run the Android application, perform the following steps: 
 1. Substitute the CGI Studio root as described in the  windows-commands/subst article. 
 Open a Command Prompt in the CGI Studio root directory (e.g., “...\cgistudio”) and type:  
 subst x: .

 
 Press  enter . The CGI root is now available under the  X: drive in Windows Explorer. 
 2. Configure local.properties: 
 
 
 
 Open local.properties.sample file from the root of the Android application. 
 Copy the content of the sample to the  local.properties file in the root of the Android application. 
 Update the USERNAME in the SDK and NDK paths to match your system. 
 Configure from where the asset should load under the Asset Configuration block. 
 Set the ABI to the target CPU architecture under the Target ABI block. 
 Save  local.properties and  sync project with Gradle files  (Ctrl+Shift+O). 
 
 
 
 Note: If the SDK or NDK paths do not exist, Android Studio may reset  local.properties after syncing the project with Gradle files. 
 3. Open the Android Application: 
 Launch Android Studio and open the project located at: 
 X:\cgi_studio_apps\References\Android\NativeViewLibrary

 
 4. Create an Android asset 
 Run the following batch file: 
 X:\bin\SceneComposer\SceneComposer_Android_OpenGLES30.bat

 
 
 
 
  Choose an asset template (e.g., “3D Basic”) and save this as Test.bin
 
 If from sdcard: to the /sdcard/ directory of the target or emulator. In Android Studio, this can be done in the "Device Explorer" of the target or emulator. 
 If from APK:  to the following folder:  
 
 
 
 
 
 X:\cgi_studio_apps\References\Android\NativeViewLibrary\sample\src\main\assets

 
 5.  Build variant: 
 
 
 
 In Android Studio, open [View | Tool Window | Build Variants]. 
 In the Build Variants tool window, select debug or release under Active Build Variant. 
 
 
 
 6.  Run the application : 
 
 
 
 Select the target device or emulator in Android Studio. 
 Click  Run (the play button) 
 The first time the Application starts, it will request permissions. Accept and restart the application. The asset should now be running. 
 
 
 
 7.  APK 
 After the application is running, the current built APK can be found in the build directory. This can located by opening [Build | Analyze APK]. The usual directory would be: 
 X:\cgi_studio_apps\References\Android\NativeViewLibrary\sample\build\intermediates\apk\

 
 If the build was for release, the APK will be signed. 
 
 Troubleshooting 
 
 If encountering any issues during the setup, refer to the official documentation for Android Studio, CMake, and NDK for troubleshooting steps.
