问题
I am developing Android app with OSM which support offline routing and navigation.
I want to integrate the offline routing and navigation in OSM for Android app. There are lots of routing software and I am confused which one is better. Can anyone compare the feature of routing and navigation of different routing providers?

You can find a comparison of routing services here: https://github.com/MKergall/osmbonuspack/wiki/WhichRoutingService
But if you want offline routing, GraphHopper will be your only solution.
