Map SDK
Map SDK will provide you with APIs for map like APIs to show the map , place markers , draw circles.
There is a lot of map SDKs available on the internet, most of them give the same features , but the difference will be in:
• Data on the map.
• Accuracy
• Controls
• Price
Setup Your Project
1. Create new android project.
2. Open Google Cloud website(https://cloud.google.com/).
3. Create new project on Google Cloud.
4. Enable the Google Map API.
5. Create API Key.

Map view & SupportMapFragment
• Map View:

• mandatory to call onCreate() to show the map.
• mandatory to all onResume() and onPause() in case you want to use the Location dot.
• SupportMapFragment:
• supports all Android API Level.
• simplest way to build map.
• need to think about the lifecycle functions
Map Configurations
Map Attributes:
1. UI Gestures
2. Camera
3. Map Type
4. UI Controls
UI Gestures:
1. Target : The camera target is the location of the center of the map, specified as latitude and longitude co-ordinates.
2. Zoom : The zoom level of the camera determines the scale of the map.
zoom level:
1. 1: World
2. 5: Landmass/continent
3. 10: City
4. 15: Streets
5. 20: Buildings
3. Bearing : Bearing is the horizontal angle between the direction of an object and another object, or between it and that of true north.

4. Tilting : The tilt defines the camera's position on an arc between directly over the map's center position and the surface of the Earth, measured in degrees from the nadir (the direction pointing directly below the camera)

Map Type:
• Normal.
• Hybrid.
• Satellite
• Terrain.
• None.
•
UI Controls:
1. Zoom Control
2. Compass
Map Camera
Ccamera:
• Camera Move

Map Markers
Markers indicate single locations on the map. You can customize your markers by changing the default color, or replacing the marker icon with a custom image
Map Polylines
Polyline is a list of points, where line segments are drawn between consecutive points
