    /* this will added in your project file by default if you choose Maps Activity whrn project was                created */
   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    // add this permission to access all networks like mobile and GPS
   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>


2) XML Layout 
 It Will Create By Default when you choose  maps activity
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    tools:context=".MapsActivity" />
