A simple Android app with Google Maps API v2. Made while learning Google Maps API. While doing this project I have learned Google Maps API, initializing map in fragments, camera operations, marking locations and so on. I have trained using GPS and determining the location of user. After 2 years I have practiced refactoring to MVVM + Clean Architecture. That was quite fun! Because I used best MVVM practices in first attempt to create this app, it was not so hard to do so :)
-
- Get an API key https://developers.google.com/maps/documentation/android-sdk/start
- Add an API key to local.properties file as shown below:
MAPS_API_KEY=your_api_keyYou don't need to add any quotation marks.
- GPS Location
- Marks your park location
- Navigate you to your park location with Google Maps
As you see - it's really basic app! 😉
Kotlin Language - modern language for JVM recommended by Google for Android Development
Google Maps API - most popular maps for Android
Koin - lightweight dependency injection framework
Kotlin Coroutines - asynchronous programming library for Kotlin
Timber - Jake Wharton's logging library
Room Persistence Library - Abstraction layer for SQLite Database
Jetpack Navigation Component - helps with navigation between fragments (maybe a overkill for this app at the moment)
