구글 위치 API 로 현재 위치 좌표 얻기

앱을 만들다보면 앱을 실행하면서 현재 위치 좌표값만 획득하고 싶을 경우가 있다.

AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" /> <!-- Android 10 이상 백그라운드 위치 액세스 요청 -->

앱 build.gradle

dependencies {     implementation fileTree(dir: "libs", include: ["*.jar"])     implementation 'androidx.appcompat:appcompat:1.1.0'     implementation 'androidx.constraintlayout:constraintlayout:1.1.3'     implementation 'gun0912.ted:tedpermission:2.0.0'     implementation 'com.google.android.gms:play-services-location:17.0.0'     implementation 'com.naver.maps:map-sdk:3.7.1' // 네이버 지도 SDK }

SplashActivity.java

public class SplashActivity extends AppCompatActivity {     private final String TAG = this.getClass().getSimpleName();     Context mContext;     private final int GPS_ENABLE_REQUEST_CODE = 2001;     private final long UPDATE_INTERVAL_MS = 1000 * 60 * 15;

                            }                             break;                         case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:                             Log.e(TAG, "Fix in Settings.");

            Log.i(TAG, "onLocationAvailability - " + locationAvailability);         }     }; }

PrefsHelper.java

public class PrefsHelper {     public static final String PREFERENCE_NAME="pref";     private Context mContext;     private static SharedPreferences prefs;     private static SharedPreferences.Editor prefsEditor;     private static PrefsHelper instance;     public static synchronized PrefsHelper init(Context context){         if(instance == null)             instance = new PrefsHelper(context);         return instance;     }     private PrefsHelper(Context context) {         mContext = context;         prefs = mContext.getSharedPreferences(PREFERENCE_NAME, Context.MODE_PRIVATE );         prefsEditor = prefs.edit();     }     public static String read(String key, String defValue) {         return prefs.getString(key, defValue);     }     public static void write(String key, String value) {         prefsEditor.putString(key, value);         prefsEditor.commit();         // double 변수 값은 string으로 감싸서 데이터를 넘기면 된다.     }     public static Integer read(String key, int defValue) {         return prefs.getInt(key, defValue); // 32비트     }     public static void write(String key, Integer value) {         prefsEditor.putInt(key, value).commit();     }     public static long read(String key, Long defValue) {         return prefs.getLong(key, defValue); // 64비트     }     public static void write(String key, Long value) {         prefsEditor.putLong(key, value).commit();     }     public static boolean read(String key, boolean defValue) {         return prefs.getBoolean(key, defValue);     }     public static void write(String key, boolean value) {         prefsEditor.putBoolean(key, value);         prefsEditor.commit();     } }

지도를 띄우지 않은 상태에서 현재 위치 좌표만 얻어지는 걸 확인할 수 있다.

참고하면 좋은 게시글
