   compile 'com.google.android.gms:play-services:9.0.0'

   
   

   apply plugin: 'com.android.application'
   
   android {
       compileSdkVersion 25
       buildToolsVersion "25.0.0"
   
       defaultConfig {
           applicationId "com.pankaj.placesearch.demo"
           minSdkVersion 15
           targetSdkVersion 25
           versionCode 1
           versionName "1.0"
           testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
       }
   
       buildTypes {
   
           release {
               minifyEnabled false
               proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
           }
       }
   }
   dependencies {
       compile fileTree(dir: 'libs', include: ['*.jar'])
       androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
           exclude group: 'com.android.support', module: 'support-annotations'
       })
       compile 'com.android.support:appcompat-v7:25.0.1'
       testCompile 'junit:junit:4.12'
   
       //______add google play service
       compile 'com.google.android.gms:play-services:9.0.0'
   }
   

    
   
3. Open your menifest.xml and update it-

   <!--mata data for place api-->
   <meta-data
       android:name="com.google.android.geo.API_KEY"
       android:value="@string/app_id" />

   
   

   <?xml version="1.0" encoding="utf-8"?>
   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
       package="com.pankaj.placesearch.demo">
   
       <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>
   
           <!--mata data for place api-->
           <!--https://console.developers.google.com/apis-->
           <meta-data
               android:name="com.google.android.geo.API_KEY"
               android:value="@string/app_id" />
       </application>
   </manifest>

10. Open your main_activity.xml and update it-
    
    

    <?xml version="1.0" encoding="utf-8"?>
    
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center_horizontal"
        android:orientation="vertical"
        tools:context="com.pankaj.placesearch.demo.MainActivity">
    
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:text="Search a place"
            android:textColor="@color/colorPrimary"
            android:textStyle="bold" />
    
        <!--add fragment to search place-->
        <fragment
            android:id="@+id/place_autocomplete_fragment"
            android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    
    </LinearLayout>
    

     
    
11. Open your MainActivity.JAVA class and update it -
    
    

    package com.pankaj.placesearch.demo;
    
    import android.os.Bundle;
    import android.support.annotation.NonNull;
    import android.support.v7.app.AppCompatActivity;
    import android.util.Log;
    import android.widget.Toast;
    import com.google.android.gms.common.ConnectionResult;
    import com.google.android.gms.common.api.GoogleApiClient;
    import com.google.android.gms.common.api.Status;
    import com.google.android.gms.location.places.Place;
    import com.google.android.gms.location.places.Places;
    import com.google.android.gms.location.places.ui.PlaceAutocompleteFragment;
    import com.google.android.gms.location.places.ui.PlaceSelectionListener;
    
    public class MainActivity extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener {
    
        //_______create object
        private GoogleApiClient mGoogleApiClient;
        private final int PLACE_AUTOCOMPLETE_REQUEST_CODE = 11;
        private String TAG = "place";
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            //________initialize google client api
            mGoogleApiClient = new GoogleApiClient
                    .Builder(this)
                    .addApi(Places.GEO_DATA_API)
                    .addApi(Places.PLACE_DETECTION_API)
                    .enableAutoManage(this, this)
                    .build();
    
            //________initialize auto complete place
            autocompletePlace();
        }
        private void autocompletePlace() {
    
            //______________create object of PlaceAutocompleteFragment.
            PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment)
     getFragmentManager().findFragmentById(R.id.place_autocomplete_fragment);
    
            //______________add listener to PlaceAutocompleteFragment.
            autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
    
                //______________Method will be auto call on selection of any place.
                @Override
                public void onPlaceSelected(Place place) {
                    // TODO: Get info about the selected place.
    
                    //______________format place name.
                    String toastMsgAuto = String.format("Place: %s", place.getName());
    
                    //______________show selected place in massage.
                    Toast.makeText(MainActivity.this, toastMsgAuto, Toast.LENGTH_LONG).show();
                }
    
                //______________Method will be auto call, if error occur on selection of any place.
                @Override
                public void onError(Status status) {
                    // TODO: Handle the error.
                    Log.i(TAG, "An error occurred: " + status);
                }
            });
        }
    
        //______________Method will be auto call, if connection fail from google server.
        @Override
        public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
            Toast.makeText(this, "Connection failed", Toast.LENGTH_SHORT).show();
