Can I use pedestrian routing in android app?

Hi,
I’m a beginner of graphhopper.

Now I’m making an android application using graphhopper. I’ve been searching whether I can use pedestrian routing in my application or not. I found out it is not possible to use pedestrian in the application on the web but I was not sure about that. so I came here to ask the official website.

Is it true I cannot use pedestrian routing in the application?
If it is not, how can I use? I read

this documentation. but it didn’t help me…

Thank you in advance.
