Can you share a link to this example?

This is an example of how to employ deep-learning on android device

Answer 1

To run this example, you must have all of the following installed:

• Simulink Support Package for Android Devices
• Embedded Coder
• MATLAB Coder Interface for Deep Learning Libraries
• Deep Learning Toolbox
• Deep Learning Toolbox Model for ResNet-18 Network
• Simulink Coder
• Computer Vision Toolbox

The androidObjectClassification model is part of the Simulink Support Package for Android Devices. You can obtain this support package using the Add-Ons Explorer.

Anyway, thank you very much. However, I believe that I have installed the simulink package for android device. It just can't work.

Does the version of matlab matter? My matlab's version is 2019a.

[Cris LaPierre]

It appears you are correct. I added the support package to R2019b and R2020b, which I had installed, and get the same error as you. It appears this is a new eample that is only available starting in R2021a.

Another way to confirm that is to look at the release-specific documentation page. The page you shared exists in the R2021a release version:

https://www.mathworks.com/help/releases/R2021a/supportpkg/android/ref/detect-and-track-objects-using-deep-learning-on-android-device.html

but not in the R2020b version:

https://www.mathworks.com/help/releases/R2020b/supportpkg/android/ref/detect-and-track-objects-using-deep-learning-on-android-device.html

If it helps, on my system, this model is located here: C:\ProgramData\MATLAB\SupportPackages\R2021a\toolbox\target\supportpackages\android\androidexamples\androidObjectClassification.slx

Thanks a lot. It's the matter of version. I have successfully opened the example.
