build.gradle(Module: app):

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.ramsandroid.mapsv2example"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.google.android.gms:play-services:8.4.0'
}


Step 2 : Generate SHA-1 fingerprint certificate key in Android Studio by following the steps given 
              below.
  • 1.Open Android Studio
  • 2.Open Your Project
  • 3.Click on Gradle (From Right Side Panel, you will see Gradle Bar)

  •                     you will see List Gradle scripts of your Project)
  • 5.Click on Your Project (Your Project Name form List (root))
  • 6.Click on Tasks
  • 7.Click on android
  • 8.Double Click on signingReport (You will get SHA1 and MD5 in Run Bar)


Step 2 : Generate google maps api key by using following steps:
  • sigin into following web site by using your google account user name and password https://console.developers.google.com
  • Next from top right corner of the web site you can one drop down box from that select create new project option and create new one by providing project name.

  • Next select credentials option from left side of the web site.
  • Next under New credentials select API key option next select Android Key and next select Add Package name and fingerprint and in next window provide your application package name SHA-1 certificate fingerprint key from Android Studio after click create button. next maps api  key will be generated next we are going to use this key in side application by using following procudure.
Step 3 :Insert following code into the AndroiManifest.xml file as follows

AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.ramsandroid.mapsv2example">

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <!--
     The following two permissions are not required to use
     Google Maps Android API v2, but are recommended.
    -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <permission
        android:name="your app package name.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-permission android:name="your app package name.permission.MAPS_RECEIVE" />
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="com.google.android.gms.version"

            android:value="@integer/google_play_services_version" />

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="place maps api key here" />
    </application>

</manifest>

Step 4 : Insert following code into your xml layou file

activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

Step 5 : If you want to see your current location in the map using marker add following in the activity as follows

MainActivity.java:

package com.ramsandroid.mapsv2example;

import android.content.Context;
import android.content.pm.PackageManager;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MainActivity extends AppCompatActivity implements OnMapReadyCallback, LocationListener {
    GoogleMap map;
    LocationManager locationManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);

        mapFragment.getMapAsync(this);

        //  map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);

        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

        if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1, 1, this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        map = googleMap;


        // map.setMyLocationEnabled(true);


    }

    @Override
    public void onLocationChanged(Location location) {

        map.clear();
        LatLng currentLocation = new LatLng(location.getLatitude(), location.getLongitude());


        MarkerOptions markerOptions = new MarkerOptions();
        markerOptions.position(currentLocation);
        markerOptions.title("i'm here");

        map.addMarker(markerOptions);

        // map.moveCamera(CameraUpdateFactory.newLatLngZoom(currentLocation, 17.0f));

        map.animateCamera(CameraUpdateFactory.newLatLngZoom(currentLocation, 17.0f));
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {

    }

    @Override
    public void onProviderEnabled(String provider) {

    }

    @Override
    public void onProviderDisabled(String provider) {

    }
}
