Why can't i start the "androidFa​ceDetectio​nAndTracki​ng"?

3 views (last 30 days)
I've started the first introductive example of the "Simulink Support Package for Android Devices" succesfully and i've also opened on Android Studio the folder ending with "ert_rtw", seeing all the java files and classes that implements this project.
But when i try to run on my Android Phone this example https://it.mathworks.com/help/supportpkg/android/ref/detect-and-track-face-on-an-android-device.html , i receive this type of error every time, and the folder "androidFaceDetectionAndTracking_ert_rtw" is always empty
Diagnostic Viewer:
Model Action Rebuild Reason =========================================================================================== androidFaceDetectionAndTracking Failed Code generation information file does not exist.
What can i do to solve the issue?

Can you please try mex setup [>>mex -setup c++] and then build model?
Find more details in below documentation:

I used [>>mex -setup] to select a compiler for the C language, instead of C++ and then the issue was fixed. Thank you for the help

Hello,
Few recommendation from myside based on the information you provided.
1) Verify the existance of the file which is to be used for code generation.
2) Check running the code generation by cutshorting the path to the file.
3) Also make sure the folders reaching to the file have proper name without spaces.
