I'm developing an app, which starts a Google Maps navigation by Intent. This works fine, as long as the device has "free" internet access. Unfortunately, the app is intended to be used on devices, which are behind a firewall, even on a mobile connection.
What URLs/Ports have to be configured on the firewall, so that the Google Maps Navigation works? I already searched online, but only found answers for using the maps API in an app directly, which is not what I want.

  • You can simply find out that yourself. Use a device with free Internet and monitor the traffic, e.g. using a monitor app like Net Monitor – Robert Jan 23 at 19:05
