Hi Matias! Google Design Guidelines (and common sense) tells you to respect platform you are designing an application for. It makes total sense. Android community hates when iOS design is getting ported as-is to Android platform. It breaks well-known experience to Android users and makes life harder. At the same time there is a number of Google apps on iOS which are heavily using Material design (and other Android UX principles) in their implementation. Just a few most noticeable examples - is Android share button, drawer icon, overflow appbar menu, FABs in such apps like Google Chrome, Google Maps, Youtube. Was it done intentionally? Or there is a technical constrain behind that like code sharing or something?
