Utility class for easy access to the device location on Android
- Android 2.2+
- Add this library to your project
-
Declare the Gradle repository in your root
build.gradle
allprojects { repositories { maven { url "https://jitpack.io" } } }
-
Declare the Gradle dependency in your app module's
build.gradle
dependencies { compile 'com.github.delight-im:Android-SimpleLocation:v1.0.1' }
-
- If you want to get the device's location with fine granularity (between 2m and 100m precision), GPS will be required. This consumes more battery but is most precise.
- If you want to get the device's location with coarse granularity only (precise to several hundred meters), the location will be retrieved from the network (Wi-Fi and cell towers). This saves battery but is less precise.
For fine location (GPS location), add the following permission in your AndroidManifest.xml
:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
For coarse location (network location), add the following permission in your AndroidManifest.xml
:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
