TLDR: You should be fine.
The content that you are referencing is indeed for Google's REST API's and states:
The Geocoding API may only be used in conjunction with a Google map; geocoding results without displaying them on a map is prohibited. For complete details on allowed usage, consult the Maps API Terms of Service License Restrictions.
This will not affect the use of the Android as far as I am aware. Referencing this answer it seems that:
Therefore there is no hard limit on the the Android GeoCode API useage, more just a fair useage policy per device (client)
From the TOS:
(a) Free Access (No Fees). Your Maps API Implementation must be generally accessible to users without charge and must not require a fee-based subscription or other fee-based restricted access. This rule applies to Your Content and any other content in your Maps API Implementation, whether Your Content or the other content is in existence now or is added later.
However:
(b) Mobile Applications.
(i) The rule in Section 9.1.1(a) (Free Access) does not apply if your Maps API Implementation is used in a mobile application that is sold for a fee through an online store and is downloadable to a mobile device that can access the online store.
(ii) The rule in Section 9.1.1(b) (Public Access) does not apply if
your Maps API Implementation is an Android application that uses the
Google Maps Android API. (However, the rule in Section 9.1.1(b)
(Public Access) will continue to apply if your Maps API Implementation
is an Android application that uses any other Maps APIs, unless the
Maps API Implementation qualifies for the exception in Section
9.1.2(a) (Enterprise Agreement with Google).)
I've always found the TOS a bit difficult to grasp myself and have ended up contacting Google. While they've always been perfectly amicable it has sometimes taken some time for a response. I hope this helps clear this up for you and anyone else that comes across it.
