Eat in SF Android Application

Requirements:

Use Google Maps API and Places API Web Service
Display restaurants in San Francisco onto the map as markers
Use the specified Google Places API key
When user taps on a Marker, App should display another screen showing details of the selected restaurant

What parts of the APIs will the app be using? How should I get such info?
How to display details of a restaurant? We may use another activity, a marker popup, a dialog or a bottom sheet.
What information should the app cache? What information should the app store in a persistent storage?
How many Markers should the app show on the screen, based on GMaps settings?
Marker API: We can use GoogleMap.OnMarkerClickListener to get the Marker that is clicked to show a bottom sheet

How to get data on restaurants for a given location? Use Place Searches (Nearby Search) with parameters: api key, restaurant type, location, radius in meters from location
How to get specific data on a restaurant? Use Place Details with a placeid. Can be done with GeoDataClient

The application will use MVP, so it consists of one activity as a view with a presenter
The presenter will contain an Interactor for GMaps and Places
The application will get restaurant data from the Places API (caching "Content" is prohibited by the TOS)
Obtain Places API data by using Retrofit and a GsonDeserializer adapter to deserialize the data into our Restaurant model
Use the restaurant data to display Markers on the map
Decide what markers to display Map callbacks
Display details by using a callback for a selected marker to present a BottomSheetFragment, and use cached data to access details
