    Every message sent to CCS receives either an ACK or a NACK response. Messages that haven't received one of these responses are considered pending. If the pending message count reaches 1000, the 3rd-party server should stop sending new messages and wait for CCS to acknowledge some of the existing pending messages.

+
    Conversely, to avoid overloading the 3rd-party server, CCS will stop sending if there are too many unacknowledged messages. Therefore, the 3rd-party server should "ACK" received messages as soon as possible to maintain a constant flow of incoming messages. The aforementioned pending message limit doesn't apply to these ACKs. Even if the pending message count reaches 1000, the 3rd-party server should continue sending ACKs to avoid blocking delivery of new messages.

    Control Flow

    - -

    Every message sent by a 3rd-party server to CCS receives either an ACK or a NACK response. A single connection can have at most 1000 messages that were sent without having yet received a response.

    - -

    To enforce this policy, the app can maintain a counter of sent messages that increments on each send and decrements on each ACK or NACK. If the counter exceeds 1000, the app should stop sending messages until an ACK or NACK is received.

    - -

    Conversely, when CCS sends messages to a 3rd-party server, it expects ACKs for each message it sends, and it will not send more than 1000 unacknowledged messages.

    - -

    The ACKs and messages must match on each connection. You can only send an ACK for a message on the connection on which it was received.

    +

    ACKs are only valid within the context of one connection. If the connection is closed before a message can be ACKed, the 3rd-party server should wait for CCS to resend the message before ACKing it again. +

    Writing Android Applications that Use GCM

    - -

    To write Android applications that use GCM, you must have an application -server that can perform the tasks described in Role of the -3rd-party Application Server. This section describes the steps you take to -create a client application that uses GCM.

    - -

    Remember that there is no user interface associated with GCM. -However you choose to process messages in your Android application is up to you.

    - -

    There are two primary steps involved in writing a client Android application:

    - -
      -
    • Creating a manifest that contains the permissions the Android application needs to -use GCM.
      • -
    • Implementing your code. To use GCM, this implementation must -include: -
        -
      • Code to start and stop the registration service.
        • -
      • Receivers for the com.google.android.c2dm.intent.RECEIVE and com.google.android.c2dm.intent.REGISTRATION intents.
        • -
      -
      • -
    - -

    Note: This section describes how to -write an app without using the -helper libraries. -For details on writing -an app that uses the helper libraries (which is the recommended and -simpler approach), see GCM: Getting Started. - -

    Creating the Manifest

    - -

    To use the GCM feature, the -AndroidManifest.xml file must include the following:

    - -
      -
    • The com.google.android.c2dm.permission.RECEIVE permission so the Android application can register and receive messages.
      • -
    • The android.permission.INTERNET permission so the Android application can send the registration ID to the 3rd-party server.
      • -
    • The android.permission.GET_ACCOUNTS permission as GCM requires a Google account (necessary only if if the device is running a version lower than Android 4.0.4)
      • -
    • The android.permission.WAKE_LOCK permission so the application can keep the processor from sleeping when a message is received. Optional—use only if the app wants to keep the device from sleeping.
      • -
    • An applicationPackage + ".permission.C2D_MESSAGE permission to prevent other Android applications from registering and receiving the Android application's -messages. The permission name must exactly match this pattern—otherwise the Android application will not receive the messages.
      • -
    • A receiver for com.google.android.c2dm.intent.RECEIVE and com.google.android.c2dm.intent.REGISTRATION, with the category set -as applicationPackage. The receiver should require the com.google.android.c2dm.SEND permission, so that only the GCM -Framework can send a message to it. Note that both registration and the receiving -of messages are implemented as Intents.
      • -
    • An intent service to handle the intents received by the broadcast receiver. Optional.
      • -
    • If the GCM feature is critical to the Android application's function, be sure to -set android:minSdkVersion="8" in the manifest. This -ensures that the Android application cannot be installed in an environment in which it -could not run properly.
      • -
    - -

    Here are excerpts from a manifest that supports GCM:

    - -
    -<manifest package="com.example.gcm" ...>
-
-    <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16"/>
-    <uses-permission android:name="android.permission.INTERNET" />
-    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
-    <uses-permission android:name="android.permission.WAKE_LOCK" />
-    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
-
-    <permission android:name="com.example.gcm.permission.C2D_MESSAGE" 
-        android:protectionLevel="signature" />
-    <uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" />
-
-    <application ...>
-        <receiver
-            android:name=".MyBroadcastReceiver"
-            android:permission="com.google.android.c2dm.permission.SEND" >
-            <intent-filter>
-                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
-                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
-                <category android:name="com.example.gcm" />
-            </intent-filter>
-        </receiver>
-        <service android:name=".MyIntentService" />
-    </application>
-
-</manifest>
-
    - -

    Registering for GCM

    - -
    -
    -

    Streamlined Registration

    -

    There is now a simpler alternative to registering and unregistering. Simply call the {@code GoogleCloudMessaging} method -{@code register(senderID...)}. -This method registers the application for GCM and returns the registration ID. To unregister, call the -{@code unregister()} method (though you should rarely if ever need to unregister).

    -
    -
    - -

    An Android application needs to register with GCM servers before it can receive messages. To register, the application sends an Intent -(com.google.android.c2dm.intent.REGISTER), with 2 extra parameters: -

    - -
      -
    • sender is the project number of the account authorized to send messages -to the Android application.
      • -
    • app is the Android application's ID, set with a PendingIntent to -allow the registration service to extract Android application information.
      • -
    - -

    For example:

    - -
    Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
-// sets the app name in the intent
-registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
-registrationIntent.putExtra("sender", senderID);
-startService(registrationIntent);
    - -

    This intent will be asynchronously sent to the GCM server, and the response will be delivered to -the application as a com.google.android.c2dm.intent.REGISTRATION intent containing -the registration ID assigned to the Android application running on that particular device.

    - -

    Registration is not complete until the Android application sends the registration ID -to the 3rd-party application server, which in turn will use the registration ID to send -messages to the application.

    - -

    Unregistering from GCM

    - -

    To unregister from GCM, do the following:

    - -
    Intent unregIntent = new Intent("com.google.android.c2dm.intent.UNREGISTER");
-unregIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
-startService(unregIntent);
-
    - -

    Similar to the registration request, this intent is sent asynchronously, and the response comes as a com.google.android.c2dm.intent.REGISTRATION intent. - - -

    Handling Intents sent by GCM

    - -

    As discussed in Creating the Manifest, the manifest -defines a broadcast receiver for the com.google.android.c2dm.intent.REGISTRATION and com.google.android.c2dm.intent.RECEIVE intents. -These intents are sent by GCM to indicate that a device was registered (or unregistered), or to deliver messages, respectively.

    - -

    Handling these intents might require I/O operations (such as network calls to the 3rd-party server), and -such operations should not be done in the receiver's onReceive() method. -You may be tempted to spawn a new thread directly, but there are no guarantees that the process will run long enough for the thread to finish the work. -Thus the recommended way to handle the intents is to delegate them to a service, such as an {@link android.app.IntentService}. -For example:

    - - -
    -public class MyBroadcastReceiver extends BroadcastReceiver {
-
-    @Override
-    public final void onReceive(Context context, Intent intent) {
-        MyIntentService.runIntentInService(context, intent);
-        setResult(Activity.RESULT_OK, null, null);
-    }
-}
-
    - -

    Then in MyIntentService:

    -
    -public class MyIntentService extends IntentService {
-
-    private static PowerManager.WakeLock sWakeLock;
-    private static final Object LOCK = MyIntentService.class;
-    
-    static void runIntentInService(Context context, Intent intent) {
-        synchronized(LOCK) {
-            if (sWakeLock == null) {
-                PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
-                sWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "my_wakelock");
-            }
-        }
-        sWakeLock.acquire();
-        intent.setClassName(context, MyIntentService.class.getName());
-        context.startService(intent);
-    }
-    
-    @Override
-    public final void onHandleIntent(Intent intent) {
-        try {
-            String action = intent.getAction();
-            if (action.equals("com.google.android.c2dm.intent.REGISTRATION")) {
-                handleRegistration(intent);
-            } else if (action.equals("com.google.android.c2dm.intent.RECEIVE")) {
-                handleMessage(intent);
-            }
-        } finally {
-            synchronized(LOCK) {
-                sWakeLock.release();
-            }
-        }
-    }
-}
-
    - -

    Note: your application must acquire a wake lock before starting the service—otherwise the device could be put to sleep before the service is started.

    - -

    Handling Registration Results

    - -

    When a com.google.android.c2dm.intent.REGISTRATION intent is received, it could potentially contain 3 extras: registration_id, error, and unregistered. - -

    When a registration succeeds, registration_id contains the registration ID and the other extras are not set. -The application must ensure that the 3rd-party server receives the registration ID. It may do so by saving the registration ID and sending it to the server. -If the network is down or there are errors, the application should retry sending the registration ID when the network is up again or the next time it starts.

    - -

    Note: Although the com.google.android.c2dm.intent.REGISTRATION intent is typically received after a request was made by the application, -Google may periodically refresh the registration ID. So the application must be prepared to handle it at any time.

    - -

    When an unregistration succeeds, only the unregistered extra is set, and similar to the registration workflow, -the application must contact the 3rd-party server to remove the registration ID (note that the registration ID is not available in the intent, -but the application should have saved the registration ID when it got it).

    - -

    If the application request (be it register or unregister) fails, the error will be set with an error code, and the other extras will not be set. - -Here are the possible error codes:

    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    Error CodeDescription
    SERVICE_NOT_AVAILABLEThe device can't read the response, or there was a 500/503 from the -server that can be retried later. The Android application should use exponential back-off and retry. See Advanced Topics for more information.
    ACCOUNT_MISSINGThere is no Google account on the phone. The Android application should ask the -user to open the account manager and add a Google account. Fix on the device -side.
    AUTHENTICATION_FAILEDBad Google Account password. The Android application should ask the user to enter his/her Google Account -password, and let the user retry manually later. Fix on the device side.
    INVALID_SENDERThe sender account is not recognized. This must be fixed on the Android application side. The developer must fix the application to provide the right sender extra in the com.google.android.c2dm.intent.REGISTER intent.
    PHONE_REGISTRATION_ERROR Incorrect phone registration with Google. This -phone doesn't currently support GCM.
    INVALID_PARAMETERSThe request sent by the phone does not contain the expected parameters. This phone doesn't currently support GCM.
    - - - - -

    Here's an example on how to handle the registration in the MyIntentService example:

    - -
    -private void handleRegistration(Intent intent) {
-    String registrationId = intent.getStringExtra("registration_id");
-    String error = intent.getStringExtra("error");
-    String unregistered = intent.getStringExtra("unregistered");
-    // registration succeeded
-    if (registrationId != null) {
-        // store registration ID on shared preferences
-        // notify 3rd-party server about the registered ID
-    }
-        
-    // unregistration succeeded
-    if (unregistered != null) {
-        // get old registration ID from shared preferences
-        // notify 3rd-party server about the unregistered ID
-    } 
-        
-    // last operation (registration or unregistration) returned an error;
-    if (error != null) {
-        if ("SERVICE_NOT_AVAILABLE".equals(error)) {
-           // optionally retry using exponential back-off
-           // (see Advanced Topics)
-        } else {
-            // Unrecoverable error, log it
-            Log.i(TAG, "Received error: " + error);
-        }
-    }
-}
    - - - -

    Handling Received Data

    - -

    The com.google.android.c2dm.intent.RECEIVE intent is used by GCM to -deliver the messages sent by the 3rd-party server to the application running in the device. -If the server included key-pair values in the data parameter, they are available as -extras in this intent, with the keys being the extra names. GCM also includes an extra called -from which contains the sender ID as an string, and another called collapse_key containing the collapse key (when in use). - -

    Here is an example, again using the MyIntentReceiver class:

    - -
    -private void handleMessage(Intent intent) {
-    // server sent 2 key-value pairs, score and time
-    String score = intent.getExtra("score");
-    String time = intent.getExtra("time");
-    // generates a system notification to display the score and time
-}
    - -

    Developing and Testing Your Android Applications

    - -

    Here are some guidelines for developing and testing an Android application -that uses the GCM feature:

    - -
      -
    • To develop and test your Android applications, you need to run and debug the -applications on an Android 2.2 system image that includes the necessary -underlying Google services.
      • -
    • To develop and debug on an actual device, you need a device running an -Android 2.2 system image that includes the Google Play Store application.
      • -
    • To develop and test on the Android Emulator, you need to download the -Android 2.2 version of the Google APIs Add-On into your SDK using the Android -SDK and AVD Manager. Specifically, you need to download the component named -"Google APIs by Google Inc, Android API 8". Then, you need to set up -an AVD that uses that system image.
      • -
    • If the GCM feature is critical to the Android application's function, be sure to -set android:minSdkVersion="8" in the manifest. This -ensures that the Android application cannot be installed in an environment in which it -could not run properly.

    • The android.permission.GET_ACCOUNTS permission as GCM requires a Google account (necessary only if if the device is running a version lower than Android 4.0.4)

      Step 2: Register for GCM

      An Android application running on a mobile device registers to receive messages by calling the {@code GoogleCloudMessaging} method {@code register(senderID...)}. This method registers the application for GCM and returns the registration ID. This streamlined approach replaces the previous -GCM registration process.

      Note the following:

      + +
        +
      • The sample primarily illustrates two things: registration, and upstream messaging. Upstream messaging only applies to apps that are running against a CCS server; HTTP-based servers don't support upstream messaging.

      • The {@code GoogleCloudMessaging} registration APIs replace the old registration process, which was based on the now-obsolete client helper library. While the old registration process still works, we encourage you to use the newer {@code GoogleCloudMessaging} registration APIs, regardless of your underlying server.

      Registering

      An Android application needs to register with GCM servers before it can receive messages. So in its {@code onCreate()} method, {@code DemoActivity} checks to see whether the app is registered with GCM and with the server:

      -
      public class DemoActivity extends Activity {

     AtomicInteger msgId = new AtomicInteger();
     SharedPreferences prefs;

+
     String regid;
 
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
 
-        // Make sure the app is registered with GCM and with the server
-        prefs = getSharedPreferences(DemoActivity.class.getSimpleName(), 
-                Context.MODE_PRIVATE);
         setContentView(R.layout.main);
-
         mDisplay = (TextView) findViewById(R.id.display);

      The app calls {@code getRegistrationId()} to see whether there is an existing registration ID stored in shared preferences:

      + +
      /**

+        Log.v(TAG, "Registration not found.");
+        return "";

+    return getSharedPreferences(DemoActivity.class.getSimpleName(), 
+            Context.MODE_PRIVATE);
+}
      + +

      If the registration ID doesn't exist, or the app was updated, or the registration ID has expired, {@code getRegistrationId()} returns an empty string to indicate that the app needs to get a new regID. {@code getRegistrationId()} calls the following methods to check the app version and whether the regID has expired:

      The way this works is that during registration, the 3rd-party server requests a {@code notification_key}. The {@code notification_key} maps a particular user to all of the user's associated registration IDs (a regID represents a particular Android application running on a particular device). Then instead of sending one message to one regID at a time, the 3rd-party server can send a message to to the {@code notification_key}, which then sends the message to all of the user's regIDs.
      
 
+
      Note: A notification dismissal message is like any other upstream message, meaning that it will be delivered to the other devices that belong to the specified {@code notification_key}. You should design your app to handle cases where the app receives a dismissal message, but has not yet displayed the notification that is being dismissed. You can solve this by caching the dismissal and then reconciling it with the corresponding notification.
+
      
+
 
      You can use this feature with either the new GCM Cloud Connection Server (CCS), or the older GCM HTTP server.

      This document gives examples of GCM server-side code for HTTP. For an example of an XMPP server (Cloud Connection Server), see Getting Started. Note that a full GCM implementation requires a client-side implementation, in addition to the server. For a complete working example that includes client and server-side code, see Getting Started.
+
+
      Requirements
      
+
      For the web server:
      
+
        
+  
      •  Ant 1.8 (it might work with earlier versions, but it's not guaranteed).
        • 
+  
      • One of the following:
+    
+  
        • 
+  
      • A Google account registered to use GCM.
        • 
+  
      • The API  key for that account.
        • 
+
      
+
      For the Android application:
      
+
        
+  
      • Emulator (or device) running Android 2.2 with Google APIs.
        • 
+  
      • The Google API project number of the account registered to use GCM.
        • 
+
      
+
      Setting Up GCM
      
+
      Before proceeding with the server and client setup, it's necessary to register a Google account with the Google API Console, enable Google Cloud Messaging in GCM, and obtain an API key from the Google API Console.
      
+
      For instructions on how to set up GCM, see Getting Started.
      
+
+
+
      Setting Up an HTTP Server
      
+
      This section describes the different options for setting up an HTTP server.
      
+
      Using a standard web server
      
+
      To set up the server using a standard, servlet-compliant web server:
      
+
        
+  
      1. From the open source site, download the following directories: gcm-server, samples/gcm-demo-server, and samples/gcm-demo-appengine.
        
+
+
+  
      2. In a text editor, edit the samples/gcm-demo-server/WebContent/WEB-INF/classes/api.key and replace the existing text with the API key obtained above.
        3. 
+  
      3. In a shell window, go to the samples/gcm-demo-server directory.
        4. 
+  
      4. Generate the server's WAR file by running ant war:
        5. 
+  
+  
        $ ant war
+
+Buildfile:build.xml
+
+init:
+   [mkdir] Created dir: build/classes
+   [mkdir] Created dir: dist
+
+compile:
+   [javac] Compiling 6 source files to build/classes
+
+war:
+     [war] Building war: dist/gcm-demo.war
+
+BUILD SUCCESSFUL
+Total time: 0 seconds
+
        
+  
+  
      5. Deploy the dist/gcm-demo.war to your running server. For instance, if you're using Jetty, copy gcm-demo.war to the webapps directory of the Jetty installation.
        6. 
+  
      6. Open the server's main page in a browser. The URL depends on the server you're using and your machine's IP address, but it will be something like http://192.168.1.10:8080/gcm-demo/home, where gcm-demo is the application context and /home is the path of the main servlet.
+    
+  
        7. 
+
      
+
      Note: You can get the IP by running ifconfig on Linux or MacOS, or ipconfig on Windows. 
      
+
+
       You server is now ready.
      
+
+
      Using App Engine for Java
      
+
+
      To set up the server using a standard App Engine for Java:
      
+
        
+  
      1. Get the files from the open source site, as described above.
        
+  
        2. 
+  
      2. In a text editor, edit samples/gcm-demo-appengine/src/com/google/android/gcm/demo/server/ApiKeyInitializer.java and replace the existing text with the API key obtained above.
+
+  
        Note: The API key value set in that class will be used just once to create a persistent entity on App Engine. If you deploy the application, you can use App Engine's Datastore Viewer to change it later.
        
+  
+  
        3. 
+  
      3. In a shell window, go to the samples/gcm-demo-appengine directory.
        4. 
+  
      4. Start the development App Engine server by ant runserver, using the -Dsdk.dir to indicate the location of the App Engine SDK and -Dserver.host to set your server's hostname or IP address:
        5. 
+
+
        +$ ant -Dsdk.dir=/opt/google/appengine-java-sdk runserver -Dserver.host=192.168.1.10
+Buildfile: gcm-demo-appengine/build.xml
+
+init:
+    [mkdir] Created dir: gcm-demo-appengine/dist
+
