Step 1 :- Create New Android Project.

Step 2 :- Add Google-play-services_lib to your project.

Step 3 :- Open AndroidManifest.xml file.

<!--?xml version="1.0" encoding="utf-8"?-->
package="com.mapv2.demo"
android:versionCode="1"
android:versionName="1.0" &gt;

&lt;uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="16" /&gt;

&lt;permission
android:name="com.mapv2.demo.permission.MAPS_RECEIVE"
android:protectionLevel="signature"/&gt;

&nbsp;

&lt;uses-feature
android:glEsVersion="0x00020000"
android:required="true"/&gt;

&lt;application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" &gt;
&lt;activity
android:name="com.mapv2.demo.MainActivity"
android:label="@string/app_name" &gt;
&nbsp;

&lt;meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyCmX7SLVHXxU9pSqb2QbAOvdnjAGUulOrk"/&gt;

&nbsp;

Step 4 :- Open activity_main.xml.

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<TextView
android:id="@+id/tv_location"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>

<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/tv_location"
class="com.google.android.gms.maps.SupportMapFragment"
/>

Step 5 :- Open MainActivity.java

package com.mapv2.demo;

import android.app.Dialog;
import android.location.Location;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import android.widget.TextView;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.GoogleMap.OnMyLocationChangeListener;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;

public class MainActivity extends FragmentActivity implements OnMyLocationChangeListener {

GoogleMap googleMap;

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

// Getting Google Play availability status
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());

// Showing status
if(status!=ConnectionResult.SUCCESS){ // Google Play Services are not available
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
dialog.show();

}else { // Google Play Services are available

// Getting reference to the SupportMapFragment of activity_main.xml
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

// Getting GoogleMap object from the fragment
googleMap = fm.getMap();

// Enabling MyLocation Layer of Google Map
googleMap.setMyLocationEnabled(true);

// Setting event handler for location change
googleMap.setOnMyLocationChangeListener(this);

}

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}

@Override
public void onMyLocationChange(Location location) {
TextView tvLocation = (TextView) findViewById(R.id.tv_location);

// Getting latitude of the current location
double latitude = location.getLatitude();

// Getting longitude of the current location
double longitude = location.getLongitude();

// Creating a LatLng object for the current location
LatLng latLng = new LatLng(latitude, longitude);

// Showing the current location in Google Map
googleMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));

// Zoom in the Google Map
googleMap.animateCamera(CameraUpdateFactory.zoomTo(15));

// Setting latitude and longitude in the TextView tv_location
tvLocation.setText("Latitude:" + latitude + ", Longitude:"+ longitude );

}
}

Step 6 :- Run Code.
