Accesses the information about the longitude, latitude, and address as well as adds/removes annotations.
Note: In order to load the map on the Android device, you would need to make sure the Google Play service is installed beforehand.
Usage example
-
City planning:
Use the Street View maps to implement a better city planning and design.
-
Fire department:
The fire control center can find out the specific position of the man who made the emergency call according to the system, and then quickly plan their arrangement to send the nearest firefighters.
-
Mountaineering:
For mountain-climbing lovers, they can identify a location according to the known longitude and latitude and vice versa.
-
Tourism:
By combining with GPS API, travel agencies can provide better vacation tips for the current location and season.
-
Turn-by-turn route navigation:
Help the user navigate along a route by providing detailed turn-by-turn directions. Map API does this by registering with the GPS API to receive repeated location updates of the user's position.
