Maps API は Navigation SDK の一部としても利用できます。これを使用して、地図固有の(ナビゲーション以外の)エクスペリエンスを構築できます。アプリにナビゲーション以外の地図エクスペリエンスとナビゲーション エクスペリエンスの両方が含まれている場合は、同じ地図インスタンスで Maps API と Navigation API を使用することをおすすめします。

If your app includes both a\nnon-navigation map experience and a navigation experience, we recommend using\nthe Maps and Navigation API on the same map instance.\n\nUse `getMapAsync` to obtain the `GoogleMap` instance\n----------------------------------------------------\n\nYou can obtain a `GoogleMap` object using either\n`SupportNavigationFragment#getMapAsync` or `NavigationView#getMapAsync`. We\nrecommend this method over holding onto the `GoogleMap` instance that might\nbecome stale once the `NavigationView` underneath is recreated.\n\nAlso be sure to clean up the `GoogleMap` retrieved from this method after it is\nno longer needed.
