Get user's current latitude-longitude and convert them in full address using FusedLocation API

The Fused Location Provider intelligently manages the underlying location technology and gives us the best location according to our needs.
WHY USE
We could choose one of the location providers (network or GPS) and request location updates or set up proximity alert. But there were two main issues with this approach:
1. In case we need to define precise location, we had to switch between network and GPS location providers (as GPS doesn’t work indoors).
2. Proximity alerts were used to notify a user about proximity to a location, and this took its toll on the battery life.
ADVANTAGE OF USING THIS API
1. Simple APIs: Lets us specify high-level needs like “high accuracy” or “low power”, instead of having to worry about location providers.
2. Immediately available: Gives our apps immediate access to the best, most recent location.
3. Power-efficiency: Minimizes out app’s use of power. Based on all incoming location requests and available sensors, fused location provider chooses the most efficient way to meet those needs.
4. Versatility: Meets a wide range of needs, from foreground uses that need highly accurate location to background uses that need periodic location updates with negligible power impact.
Note : Make sure Google Play services is properly installed and working in our device. Please don’t test this location api in emulator because this api is not working in the emulator.
STEP -1 :  create main_activity.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:lib="http://schemas.android.com/apk/res-auto"
    android:background="#10000000">

    

    <TextView
        android:id="@+id/lblLocation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:padding="15dp"
        android:textColor="#fff"
        android:textSize="@dimen/abc_action_bar_content_inset_material"
        android:background="@android:color/transparent"
        android:layout_centerVertical="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:shadowColor="@color/text_shadow"
        android:shadowDx="1"
        android:shadowDy="1"
        android:shadowRadius="2"
        />
</RelativeLayout>


STEP -2 :  Add dependency in build.gradle file




dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.google.android.gms:play-services:8.3.0'
}

STEP -4 :  Add below permissions in AndroidMenifiest.xml






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






Also write meta in Application tag in menifiest file






<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version">
</meta-data>
