Get Current Location in Android

 First you must take care of premissions  so , you should add this premissions to your mainfist file 

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

Then in your gradle file add Google Location debendency 

implementation 'com.google.android.gms:play-services-location:18.0.0'

So , now we can create our location request field 

private LocationRequest locationRequest;
