    text
    copied!<p>Does anybody can help me with a working example for receiving messages from gcm using Google Cloud Messaging for Android. I have tried both ways (helper library and GoogleCloudMessaging class) and nothing seems to work. I'm using a PHP script that shows the following:</p> <p>Multicast ID: 5.2108110103215E+18 Number of messages processed successfully: 1 Number of messages with processing errors: 0 Canonical IDs: 0</p> <p>So apparently everithing is OK. I could register the device in both ways, using the helper library (gcm.jar) and using GoogleCloudMessaging class. The problem is that there is no way the message I send via PHP arrives, or at least I don't know how to handle it correctly. Here are the permissions and the receiver from my manifest:</p> <pre><code>&lt;permission android:name="com.example.gcm.permission.C2D_MESSAGE" android:protectionLevel="signature" /&gt; &lt;uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" /&gt; &lt;uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /&gt; &lt;uses-permission android:name="android.permission.INTERNET" /&gt; &lt;uses-permission android:name="android.permission.GET_ACCOUNTS" /&gt; &lt;uses-permission android:name="android.permission.WAKE_LOCK" /&gt; &lt;uses-permission android:name="android.permission.USE_CREDENTIALS" /&gt; &lt;uses-permission android:name="android.permission.READ_OWNER_DATA" /&gt; &lt;receiver android:name="com.google.android.gcm.GCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" &gt; &lt;intent-filter&gt; &lt;!-- Receives the actual messages. --&gt; &lt;action android:name="com.google.android.c2dm.intent.RECEIVE" /&gt; &lt;!-- Receives the registration id. --&gt; &lt;action android:name="com.google.android.c2dm.intent.REGISTRATION" /&gt; &lt;category android:name="com.example.gcm" /&gt; &lt;/intent-filter&gt; &lt;/receiver&gt; &lt;service android:name=".GCMIntentService" /&gt; </code></pre> <p>Finally here is the service class</p> <pre><code>public class GCMIntentService extends GCMBaseIntentService { private static final String PROJECT_ID = "49XXXXXXXX6"; private static final String TAG = "GCM Intent Service"; public GCMIntentService() { super(PROJECT_ID); Log.d(TAG, "GCMIntentService init"); } @Override protected void onError(Context ctx, String sError) { Log.d(TAG, "Error: " + sError); } @Override protected void onMessage(Context ctx, Intent intent) { Log.d(TAG, "Message Received"); String message = intent.getStringExtra("message"); sendGCMIntent(ctx, message); } private void sendGCMIntent(Context ctx, String message) { Intent broadcastIntent = new Intent(); broadcastIntent.setAction("GCM_RECEIVED_ACTION"); broadcastIntent.putExtra("gcm", message); ctx.sendBroadcast(broadcastIntent); } @Override protected void onRegistered(Context ctx, String regId) { Log.d(TAG, regId); // Notify main UI to update registration status Intent registrationIntent = new Intent(); registrationIntent.setAction("registered"); registrationIntent.putExtra("regId", regId); sendBroadcast(registrationIntent); } @Override protected void onUnregistered(Context ctx, String regId) { //... } } </code></pre> <p>Here is the code when using the GoogleCloudMessaging class (I changed the manifest to use the custom receiver):</p> <pre><code>public class GCMBroadcastReceiver extends BroadcastReceiver { private static final String TAG = "GCM Receiver"; public static final int NOTIFICATION_ID = 1; private NotificationManager mNotificationManager; private Context ctx; @Override public void onReceive(Context context, Intent intent) { Log.d(TAG, "Message received"); GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context); ctx = context; String messageType = gcm.getMessageType(intent); if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) { sendNotification("Send error: " + intent.getExtras().toString()); } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED .equals(messageType)) { sendNotification("Deleted messages on server: " + intent.getExtras().toString()); } else { sendNotification("Received: " + intent.getExtras().toString()); } setResultCode(Activity.RESULT_OK); } // Put the GCM message into a notification and post it. private void sendNotification(String msg) { mNotificationManager = (NotificationManager) ctx .getSystemService(Context.NOTIFICATION_SERVICE); PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, new Intent(ctx, MainActivity.class), 0); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder( ctx).setSmallIcon(R.drawable.ic_launcher_temp) .setContentTitle("GCM Notification") .setStyle(new NotificationCompat.BigTextStyle().bigText(msg)) .setContentText(msg); mBuilder.setContentIntent(contentIntent); mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build()); } </code></pre> <p>} </p> <p>The thing is that everything seems to be ok, but the message never arrives. Any ideas?? Thanks in advance.</p>
