notification - Se envió el servidor Android GCM, pero GCM no empuja al dispositivo

push notifications android studio

Question

Estoy probando GCM en mi teléfono celular. (2.3.6 Android).

Archivo de manifiesto (actividad principal, primera y segunda actividad no hacen nada, están ahí para algún otro propósito de prueba, sin interferir con GCM).

GCMBroadcastReceiver

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    // Explicitly specify that GcmIntentService will handle the intent.
    ComponentName comp = new ComponentName(context.getPackageName(),
            GcmIntentService.class.getName());
    // Start the service, keeping the device awake while it is launching.
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);
}
}

GCMIntentSErvice

public class GcmIntentService extends IntentService {
public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;

public GcmIntentService() {
    super("GcmIntentService");
}
public static final String TAG = "GCM Demo";

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    // The getMessageType() intent parameter must be the intent you received
    // in your BroadcastReceiver.
    String messageType = gcm.getMessageType(intent);

    if (!extras.isEmpty()) {  // has effect of unparcelling Bundle
        /*
         * Filter messages based on message type. Since it is likely that GCM will be
         * extended in the future with new message types, just ignore any message types you''re
         * not interested in, or that you don''t recognize.
         */
        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
            sendNotification("Send error: " + extras.toString());
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
            sendNotification("Deleted messages on server: " + extras.toString());
        // If it''s a regular GCM message, do some work.
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
            // This loop represents the service doing some work.
            for (int i = 0; i < 5; i++) {
                Log.i(TAG, "Working... " + (i + 1)
                        + "/5 @ " + SystemClock.elapsedRealtime());
                try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                }
            }
            Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
            // Post notification of received message.
            sendNotification("Received: " + extras.toString());
            Log.i(TAG, "Received: " + extras.toString());
        }
    }
    // Release the wake lock provided by the WakefulBroadcastReceiver.
    GcmBroadcastReceiver.completeWakefulIntent(intent);
}

// Put the message into a notification and post it.
// This is just one simple example of what you might choose to do with
// a GCM message.
private void sendNotification(String msg) {
    mNotificationManager = (NotificationManager)
            this.getSystemService(Context.NOTIFICATION_SERVICE);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, DemoActivity.class), 0);

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
    .setSmallIcon(R.drawable.abc_ab_solid_dark_holo)
    .setContentTitle("GCM Notification")
    .setStyle(new NotificationCompat.BigTextStyle()
    .bigText(msg))
    .setContentText(msg);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
}

Ahora, puedo enviar el mensaje desde el servidor como se muestra

Enviar la solicitud ''POST'' a la URL: https://android.googleapis.com/gcm/send Código de respuesta: 200 {"multicast_id": 5410443299609525979, "success": 1, "failure": 0, "canonical_ids": 0, "resultados": [{"message_id": "0: 1409160055237618% a13ced80f9fd7ecd"}]}

Pero después de eso, no veo que se genere la notificación en mi teléfono. Que está sucediendo aquí. ¿Cuáles podrían ser las posibles razones para esto?

Estoy conectado al wifi en casa, también tengo el paquete de datos activado en mi teléfono, incluso si desconté el wifi (no estoy seguro de por qué eso afectaría de todos modos, pero la solución aquí sugerida ) pero aún no recibo ninguna notificación generada .

Cualquier ayuda será muy apreciada.

Answer 1

Obtuvo la categoría incorrecta en su receptor ( <category android:name="com.google.android.gcm.demo.app" /> ). com.example.testconnectionapp a com.example.testconnectionapp , suponiendo que ese sea el nombre del paquete de su aplicación.
