Phonegap 从后台推送通知 OnResume，它会从托盘中删除我的所有通知答案

【问题标题】：Phonegap Push notification OnResume from Background, it deletes all my notification from TrayPhonegap 从后台推送通知 OnResume，它会从托盘中删除我的所有通知
【发布时间】：2015-04-02 08:11:26
【问题描述】：

我想知道如何处理 Phonegap 推送通知的 onResume 函数。当我通过单击图标恢复应用程序时，托盘中的推送通知全部被擦除，但没有事件回调，没有消息被附加，它们只是消失了。

前景

if (e.foreground) {

            $("#app-status-ul").append('<li>--INLINE NOTIFICATION--' + '</li>');

            // if the notification contains a soundname, play it.
            var my_media = new Media("/android_asset/www/"+e.soundname);
            my_media.play();
            }

简历

would i do 
function onResume() {
onNotificationGCM = function(e) {
$("#app-status-ul").append('

--INLINE NOTIFICATION--' + '');
}
}
document.addEventListener("resume", onResume, true);

我的 JavaScript

if (e.foreground)               {
                 $("#app-status-ul").append(e.payload.title);

                     if(e.payload.message="works"){

    $("#app-status-ul").append('Is this working!!');

                     }

                // if the notification contains a soundname, play it.
                var my_media = new Media("/android_asset/www/"+e.soundname);
                my_media.play();
                }else{  // otherwise we were launched because the user touched a notification in the notification tray.
                    if (e.coldstart)
                    $("#app-status-ul").append('<li>--COLDSTART NOTIFICATION--' + '</li>');
                    else
 if(e.payload.message="works"){

    $("#app-status-ul").append('Is this working?!!');

                     }                }

全套Javascript

  var pushNotification;

        function onDeviceReady() {
        //alert("onDeviceReady");

        document.addEventListener("backbutton", function(e)         {

            {
            // call this to get a new token each time. don't call it to reuse existing token.
            //pushNotification.unregister(successHandler, errorHandler);
            e.preventDefault();
            navigator.app.exitApp();
            }       else        {
            navigator.app.backHistory();

【问题讨论】：

所以基本上当您的应用程序处于前台时，您会收到一些可以在托盘中看到的推送通知。但是当您按下主页按钮时收到通知后，应用程序会进入后台并且托盘也会清除它的所有通知。但是您希望通知完好无损？？？
对不起，我解释得不够清楚。当应用程序在前台时，它可以完美地工作，消息被推送到应用程序中，它在后台时也可以工作。唯一不起作用的是，当应用程序在后台时，手机收到推送通知它位于托盘中，我单击应用程序图标恢复到应用程序，然后没有 ECB 回调和托盘被清除（一旦应用程序进入前台，推送通知消失并且应用程序永远不会收到消息）。因此，当单击应用程序图标时应用程序恢复时，我需要 ECB 回调。
好的...然后我给出一个解决方案作为答案，检查后让我知道它是否有效。
@john：确认的一件事，你不想在点击推送后清除通知？？？或者只是想清除特定的通知？？？
我真的不介意，只要将推送消息放入应用程序，我就可以清除它。要点是那些消息（托盘中的推送消息）刚刚消失，我无法将它们放入应用程序。因为有 3 种情况，如果是 e.foreground，如果是 e.coldstart，如果是 e.background。但是当我点击图标恢复时。没有涵盖这种情况。

【解决方案1】：

首先打开com.plugin.gcm包下的GCMIntentService.java文件。在那里你会发现

public void createNotification(Context context, Bundle extras)

方法。有一行包含类似

mBuilder = new NotificationCompat.Builder(context)
            .setDefaults(Notification.DEFAULT_ALL)
            .setSmallIcon(context.getApplicationInfo().icon)
            .setWhen(System.currentTimeMillis())
            .setContentTitle("Notification")
            .setContentText(jsonObject.getString("alert"))
            .setTicker(extras.getString("title"))
            .setContentIntent(contentIntent);

在该对象的末尾添加以下属性

.setAutoCancel(true);

onNotificationGCM(e)函数中的javascript端，有一个块

case 'message':
     // if this flag is set, this notification happened while we were in the foreground.
     // you might want to play a sound to get the user's attention, throw up a dialog, etc.
     if ( e.foreground ){

     }else{  // otherwise we were launched because the user touched a notification in the notification tray.
            //when app in background
     }

     navigator.notification.alert(e.payload.msg);

break;

这里的e.payload.msg是GCM返回的数据

【讨论】：

这只是删除通知托盘对吗？但是当我单击应用程序图标以恢复应用程序时仍然没有事件回调。
那很奇怪，我试过你的代码，我也在上面发布了我的代码，我已经有了 e.foreground，还有 e.coldstart 等。但是当我恢复应用程序时，ECB 不起作用通过单击应用程序图标。当您单击应用程序图标打开应用程序时，您的消息是否加载（ECB 触发？）？
是的，在我的代码中 ecb 着火了。我认为您的代码中有一些错误。您可以在点击通知时在控制台中检查它会引发什么错误吗？
当我点击托盘中的通知或当应用程序处于前台时它们会触发，只是当我通过单击应用程序图标恢复应用程序时不会触发。我可以提醒 console.log 看看吗？我已经有 $("#app-status-ul").append('
ERROR -> MSG:' + e.msg + '

我也将我的整个 javascript 和我的 config.xml 一起发布在那里，我感觉它可能与我的配置有关。我需要一个 document.addEventListener("resume", onResume, true);当我点击应用程序恢复时，欧洲央行的一部分？
