you have to add a dependency in gradle file
dependencies {
implementation 'com.google.android.gms:play-services-location:15.0.1'
}
apply plugin: 'com.google.gms.google-services'
give some Location permissions in your Manifest file
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-feature
android:name="android.hardware.location.gps"
android:required="true"/>
Now Create your Location finder Activity
