Google Maps provides a set of classes and APIs that developers can use to integrate interactive maps and location-based services into their applications. These classes allow developers to customize and control the behavior of the map, handle user interactions, and access various features provided by Google Maps.

Here are some key classes used in Google Maps:
1. MapView: The MapView class represents the visual component that displays the map on the screen. It is typically added to the application's layout and provides methods to control the appearance and behavior of the map, such as zooming, panning, and adding markers or overlays.
2. GoogleMap: The GoogleMap class is the main interface for interacting with the map. It provides methods for controlling the camera position and zoom level, adding markers, overlays, and polygons, and handling various user interactions like clicks and gestures. Developers can obtain an instance of GoogleMap from a MapView or MapFragment.
3. Marker: The Marker class represents a point of interest or a specific location on the map. It allows developers to add markers at desired positions, customize their appearance (e.g., icon, title, snippet), and handle events when the marker is clicked or dragged.
4. Polyline: The Polyline class represents a sequence of connected line segments on the map. It is useful for drawing routes or paths between multiple locations. Developers can define the polyline's geometry by providing a list of LatLng points and customize its appearance, such as color, width, and pattern.
5. Polygon: The Polygon class represents a closed shape with multiple connected line segments on the map. It is commonly used to highlight or enclose an area of interest. Developers can define the polygon's geometry by specifying a list of LatLng points, customize its appearance, and handle events associated with the polygon.
6. Circle: The Circle class represents a circular region on the map. It is often used to display a radius around a specific location. Developers can define the circle's position, radius, and appearance, and interact with it by handling events like clicks or drags.
7. InfoWindow: The InfoWindow class represents a popup window that appears when a marker is clicked. It can display additional information or actions related to the marker. Developers can customize the content and appearance of the info window, and handle events when it is opened or closed.
8. MapFragment and MapActivity: MapFragment and MapActivity are specialized classes that simplify the integration of Google Maps into Android applications. MapFragment is a fragment that contains a MapView, while MapActivity is an activity that hosts a MapView. These classes provide lifecycle management and handle the initialization and rendering of the map.
These are just a few of the main classes in Google Maps. There are additional classes and interfaces available for handling map events, geocoding (converting addresses to coordinates), reverse geocoding (converting coordinates to addresses), and other advanced features. Developers can refer to the official Google Maps documentation for more detailed information and usage examples of these classes.
