I'm developing a company specific Android application that uses Maps SDK for Android and Google Maps Intents for Android (com.google.android.apps.maps) to show some markers on Google map. Users use directions and streetview Apis on these maps as well. The application will not be published on Google Play as it is completely company specific. Employees will use the app on special company provided devices not on theirs own mobiles. The company provided devices are behind a firewall allowed only to reach some services part of the project.
My question: what firewall rules (domain whitelists) should be configured to reach Maps SDK for Android and Google Maps Intents for Android services?
