Why do I get an error when deploying to Android Device hardware?

I am trying to run the example, "Color Detection" of the Simulink Support Package for Android Devices, available at https://www.mathworks.com/help/simulink/supportpkg/android_ref/color-detection.html#d117e10164

When I try to deploy to hardware, i.e. in Task 2, Step 7 and in Task 3, Step 4 I receive the following error message:

Execution failed for task ':libraries:opencv:compileDebugAidl'.
> java.io.IOException: com.android.ide.common.process.ProcessException: Error while executing process

Why does it fail? What can I do to make it work, so that I can deploy to my Android device?

Please note, the Camera block works fine with Android SDK Build Tools 28.0.3. However, if build tool version 29.0.0-rc2 is present then the above issue comes up.

 

To resolve the issue, you can uninstall build tool 29.0.0-rc2 and install version 28.0.3. After uninstalling, please run Android Hardware setup again. Then try deploying the model to the Android Device.
