我有一些服务器端代码,我正在尝试创建推送通知。结果如下所示:

{"multicast_id":8714083978034301091,"success":1,"failure":0,"canonical_ids":0,"r‌​esults":[{"message_id":"0:1350807053347963%9aab4bd8f9fd7ecd"}]}

这是我用来发送推送通知的 PHP 代码。顺便说一下,推动没有发生,所以我试图找出原因:

$url = 'https://android.googleapis.com/gcm/send';

$device_ids = array( $device_id );

$t_data = array();
$t_data['message'] = 'Someone commented on your business.';

$t_json = array( 'registration_ids' => $device_ids , 'data' => $t_data );

// Open connection
$ch = curl_init();

curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Authorization: key=my_key', 'Content-Type: application/json' ) );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode( $t_json ) );

curl_setopt($ch, CURLOPT_URL, $url);

// Execute post
$result = curl_exec($ch);    

if ($result === FALSE)
{   
   die('Curl failed: ' . curl_error($ch));
}

// Close connection
curl_close($ch);

这是我的整个 GCMIntentService 类:

    return(true);
  } 

  private static void generateNotification(Context context, String message, String title ) 
  {
        int icon = R.drawable.ic_launcher;
        long when = System.currentTimeMillis(); // can change this to a future time if desired

        NotificationManager notificationManager = 
                (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        Intent notificationIntent = new Intent(context, ProblemioActivity.class);

        // set intent so it does not start a new activity
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);        
        Uri defaultSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);            

         Notification notification = new NotificationCompat.Builder(context)
         .setContentTitle(title)
         .setContentText(message)
         .setContentIntent(intent)
         .setSmallIcon(icon)
         .setLights(Color.YELLOW, 1, 2)
         .setAutoCancel(true)
         .setSound(defaultSound)
         .build();

        notificationManager.notify(0, notification);
}     

}

但无论我尝试什么,推送通知都不会出现在物理设备上。有什么想法为什么不以及如何让它出现在设备上?

您只需要将对通知函数的调用添加到 onMessage() 中,如下所示:

@Override
protected void onMessage(Context ctxt, Intent message) {
    Bundle extras=message.getExtras();

    for (String key : extras.keySet()) {
      Log.d(getClass().getSimpleName(),
            String.format("onMessage: %s=%s", key,
                      extras.getString(key)));
    }
    generateNotification(ctxt, extras.getString("message"), "test title");

}

您实际上需要在方法中手动生成通知onMessage()。onMessage() 只是一个方法,当您的应用程序从服务器接收到痒痒时将调用该方法。您可能并不总是希望向用户生成可见的状态栏通知。因此,Google 提供了仅在需要时才发布通知的灵活性。无论如何,这里的代码将帮助您生成此通知。显然,您可以根据自己的需要进行调整。

private void generateNotification(Context context, String message)
{
    // put an icon for your notification in your res/drawable folder
    // and then get the icon as an int
    int icon = R.drawable.notif_icon_name;
    long when = System.currentTimeMillis(); // can change this to a future time if desired
    NotificationManager notificationManager = (NotificationManager) context
         .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);
    String title = context.getString(R.string.app_name);
    Intent notificationIntent = new Intent(context, BaseActivity.class);
    // set intent so it does not start a new activity
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
        | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.defaults |= Notification.DEFAULT_SOUND;
    notificationManager.notify(0, notification);
}
