Additional items that need to be installed from the “SDK Manager” of Android Studio are described in the next section.

Setup Procedure

Android Studio

Install the integrated development environment. The default settings are acceptable.
After installation, select SDK Manager from the “Tools” tab to install additional required tools.

  1. Go to [SDK Platforms] and check the [Android 12.0(S)] checkbox.
  2. Install the “SDK Tools” tool as shown in the following image.

Note: Android Emulator has the ability to improve performance by using the hardware acceleration feature.
Intel processors: Intel x86 Emulator Accelerator (HAXM installer)
AMD processors: Android Emulator Hypervisor Driver for AMD Processors (installer)
However, if Hyper-V is enabled, “Windows Hypervisor Platform” must be enabled.
See the Android Studio User Guide for more information.


The Android project uses Gradle as its build tool. After starting the sample application,
press “Build” -> “Rebuild Project” and execute Gradle Build.


If the build is successful, you are ready to execute the application. If you have an Android device, you can connect the actual device and run it on the device. If you do not have one, please run it on an emulator.
If the execution is successful, the application and execution log will be displayed as shown below.
Note: In the Minimum Demo, UI such as the background and the gear icon for switching models are not displayed.

In addition to the normal samples, this application provides a “Minimum Demo” with only the minimum functions.
It is possible to change the application to run by switching the “build variant.”

  1. Click the “Build Variants” in the left corner.

2. Click on Active Build Variants and select “ModelSpawner”.
