A Google Cloud Messaging GCM Android client is a client app that runs on an Android device. To write your client code, we recommend that you use the GoogleCloudMessaging API and Android Studio with Gradle. A full GCM implementation requires both a client implementation and a server implementation. For more information about implementing the forex side, see About GCM Connection Server. The following sections walk you through the steps involved in writing a GCM client-side application forex Android. At a minimum, a GCM client app must include code to register and thereby get a registration tokenand a receiver to receive messages sent by GCM. New Cloud Messaging projects must create a Firebase project in the Firebase console. In this process, you'll generate a configuration file and credentials forex your project. The Google Services plugin for Gradle parses configuration information from the google-services. Add the plugin to your project by updating your top-level build. To write your client application, use the GoogleCloudMessaging API. To use this API, you must set up your project to use the Google Play services SDK, as described in Set up Google Play Services SDK.

The key point is that you must reference the library—simply adding a. If you're gcm Android Studio, this gcm the string to add to the dependency section of your application's build. Apps that rely on the Play Services SDK should always check the device for a compatible Google Play services APK before accessing Google Play services features. Facebook is recommended to do this in two places: The check in onCreate ensures gcm the app can't be used without a successful check. The check in onResume ensures that if the user gcm to the running app through some forex means, such as through the back button, the check is still performed. If the device doesn't have a compatible Google Play services APK, your app can call GooglePlayServicesUtil. For a code example, see Set up Google Play Services SDK. An Android application needs to register with GCM connection servers before it can receive messages. When an app registers, facebook receives a registration token and sends it to the app server. The client app should store a boolean value indicating whether the registration token has been sent to the server. Google provides the Instance ID API gcm handle the creation and updating of registration tokens. To use this API, include InstanceIDListenerService in the manifest:. To obtain a token, call instanceID. Do not call this method in the main thread; instead, use a service that extends IntentService as shown:. The listener service's onTokenRefresh method gcm be invoked if the GCM forex token has been refreshed:. Once onTokenRefresh is called, use InstanceID. See the Instance ID API reference for full detail on this API. Forex the client app is connected, you are ready to start receiving downstream messages and sending upstream messages.

For existing apps that extend a WakefulBroadcastReceiverGoogle recommends migrating to GCMReceiver and GcmListenerService. Gcm the app manifest, replace your GcmBroadcastReceiver with "com. GcmReceiver", and replace the current service declaration that extends IntentService to the new Facebook Remove the BroadcastReceiver implementation from your client code Refactor the current IntentService service implementation to use GcmListenerService For details, see the example manifest and code samples in this page.
