Android谷歌云消息传递 - 推送到设备，但设备不显示推送通知

Question

我有一些服务器端代码，我试图创建推送通知。结果是这样的：

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

这里是我用来发送推送通知的PHP代码。顺便说推并没有发生，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);

     .setAutoCancel(true) 
     .setSound(defaultSound) 
     .build(); 

     notificationManager.notify(0, notification); 
}  

}

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

Answer 1

你只需要添加到的onMessage（）调用的通知功能，像这样：

@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"); 

}

您需要在onMessage()方法中实际手动生成通知。 onMessage（）只是一个方法，当你的应用程序从服务器收到痒痒的时候会被调用。您可能并不总是希望为用户生成可见的状态栏通知。所以谷歌给了灵活性，只要你想要通知。无论如何，这里的代码将帮助您生成此通知。显然，你可以根据自己的需要调整它。

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); 
}
