The source code is

package com.dutt.rishabh.locator;

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;

import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }


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

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-34, 151);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
    }
}

The gradle build file

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"
    defaultConfig {
        applicationId "com.dutt.rishabh.locator"

    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-v7:24.0.0'
    compile 'com.google.android.gms:play-services:9.2.0'
    testCompile 'junit:junit:4.12'
}

Don't include the whole play services library but use the one that you need, I think that replacing the line:

compile 'com.google.android.gms:play-services:9.2.0'

with:

compile 'com.google.android.gms:play-services-maps:9.2.0'

should solve your problem

@Rishabh glad it worked :) Btw now it crashes because name == null , I don't know where in the code you're setting that but it's causing the crash

Rishabh Over a year ago

Can u explain please?

LS_ Over a year ago

@Rishabh I don't know because I don't have the full code, you should setup some breakpoints and check where it's crashing

As part of enabling Google APIs or Firebase services in your Android application you may have to add the google-services plugin to your root build.gradle file:

dependencies {
    classpath 'com.google.gms:google-services:3.0.0'
    // ...
}

Then at the bottom of your app/build.gradle add:

apply plugin: 'com.google.gms.google-services'
