More about Google Play Services
Google Play services is an essential app to use Google apps. Other applications like Whatsapp, Facebook, and Instagram also require play services to work properly on your Android. It also helps to update apps from Google Play Store. This app provides core functionality like authentication to your Google accounts, synchronized contacts, and location services that work in the background.
Google Play services also enhance your app experience. Please note that some Apps may not work if you uninstall Google Play services from your device. This app is also an essential component of the Google Play store.
The main purpose of this application is to authenticate its user. Moreover, it can access its user privacy settings and all kind of location services. This Application also enriches the user experience towards other applications. Offline, it improves the speed of searches and maps. This application improves the working of different apps downloaded from Google Play. Sometimes the Applications/Games don’t work without the installation of Google Play Services. For more information about this, you can visit google support.
This app is a feature of Google Play to update any Google apps or the apps downloaded from the Google Play Store. The purpose of this app is to offer the following functionalities.
- Authenticity to your Google services

- Open the left menu again and tap Settings. Scroll to the bottom of this page and tap the Play Store version to check for updates to the Google Play app.
- Restart your device and then launch the Play Store again.

The Google Services Gradle Plugin
Introduction
As part of enabling Google APIs or Firebase services in your Android application you may have to add the google-services plugin to your build.gradle file:
The google-services plugin has two main functions:
- Process the google-services.json file and produce Android resources that can be used in your application’s code. See Adding the JSON File more information.
Add dependencies for basic libraries required for the services you have enabled. This step requires that you apply the Google Services Gradle plugin in your app/build.gradle file, like so:
apply plugin: ‘com.google.gms.google-services’
You can see the result of this step by running ./gradlew :app:dependencies .
Adding the JSON File
The google-services.json file is generally placed in the app/ directory (at the root of the Android Studio app module). As of version 2.2.0 the plugin supports build type and product flavor specific JSON files. All of the following directory structures are valid:
Note: Providing a google-services.json file in the release directory allows you to maintain a separate Firebase project for your production APKs.
When product flavors are in use these more complicated directory structures are also valid.
Processing the JSON File
The google-services.json file has the following basic structure:
The project_info object contains general information about your project, while each member of the client array contains information about the clients (Android apps) that you have added to the project.
When processing the JSON file for your Android app, the plugin only uses the client object that matches your package name (for the current build type) based on the following logic:
- For each member of the client array:
- Check the value of client_info/android_client_info/package_name
- If the package name matches this value, return the member object.
- If none of the members of client match the package name, an exception is thrown.
For the rest of this document we will use
The main result of the JSON processing is to produce two XML files which you can reference as Android resources in your Java code. Below is an example of each file:
app/build/generated/res/google-services/
app/build/generated/res/google-services/
Every value in the XML files is present in the google-services.json file at the locations below. If your Android project has some configuration that prevents you from using the google-services plugin, you can safely recreate the XML files manually using these values:
google_app_id:
gcm_defaultSenderId:
default_web_client_id:
ga_trackingId:
firebase_database_url:
google_api_key:
google_crash_reporting_api_key:
project_id:
Troubleshooting
Q: When building I get the following error message: «File google-services.json is missing from module root folder. The Google Services Plugin cannot function without it».
A: The Firebase console will help you download the google-services.json . In addition, the Quickstart guides for most APIs have instructions for generating this file. Once you have downloaded the google-services.json file, copy it into the app/ folder of your Android Studio project, or into the app/src/
Q: I can’t find the symbol «R.string.gcm_defaultSenderId», «R.xml.global_tracker», etc.
A: Make sure the package name in your build.gradle file matches the package name you entered when creating the google-services.json file. If you are not sure, run through the getting started flow again and get a new json file.

Set up Google Play services
To develop an app using Google Play services APIs, follow the instructions on this page to set up your project with the relevant SDKs, which are available from the Google maven repository.
To test your app when using Google Play services, you must use one of the following:
- A compatible Android device that runs Android 4.4 (API level 19) or higher and has the Google Play Store app installed.
- The Android emulator with an AVD that runs the Google APIs platform based on Android 4.4 (API level 19) or higher.
Declare dependencies for Google Play services
To develop features that depend on the Google Play services APIs in your app, complete the following steps:
Open the build.gradle file inside your app’s module directory.
For each SDK that your app requires, include the dependency for that SDK. This page includes a section that lists common Google Play services dependencies for Android apps. You might also want to add Firebase dependencies to your project.
Save the changes and sync your project.
The following snippet shows an example build.gradle file that uses the location library:
New versions of the Google Play services SDKs with bug fixes and new features are periodically released. These updates are announced in the release notes. If your app uses a dependency that has been updated, change to the latest version in your app’s dependencies to take advantage of these fixes.
Check whether Google Play services is installed
As described in the Google Play services overview, Google Play services receives automatic updates on Android 4.4 (API level 19) and higher through the Google Play Store app. However, Android devices without Google Play Store don’t have Google Play services installed. If your app runs on devices without Google Play services, you might want to check to see if Google Play services is installed on the device before you attempt to use Google APIs, or enable features in your app that require Google Play services to function.
To check for the presence of Google Play services on the device, use the isGooglePlayServicesAvailable() method.
To then begin a connection to Google Play services, or learn how to detect whether the version of Google Play services installed supports a specific API, read the guide on Accessing Google APIs.
