[Android/Java] naver map api

Demo

1. Api Key 발급

https://www.ncloud.com/

 

2. 내위치 가져오기

• 해당 앱이 권한이 있어야한다.
• 안드로이드시스템 설정에서 위치서비스가 켜져있어야 한다.

 

dependency 추가

현재 위치를 얻기위해선 LocationProvider라는 표준 라이브러리를 사용해도 되지만 가볍고 더좋은게 google꺼라고 한다

implementation 'com.google.android.gms:play-services-location:16.0.0'

Naver sdk

allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
        maven {
            url 'https://naver.jfrog.io/artifactory/maven/'
        }
    }
}

 

implementation 'com.naver.maps:map-sdk:3.12.0'
