Android pubnub-发布回退以推送通知'；行不通

我正在使用带有pubnub的android

我做了订阅/发布教程，它工作了，我有一个工作聊天（当应用程序打开时）

阅读了所有教程后，我了解到，当应用程序处于后台或关闭状态时，

publish

方法应该回退，向

subscribe

和

enablePushNotificationsOnChannel

订阅频道的所有人发送推送通知

出于某种原因，它对我不起作用，我也不确定它应该如何起作用

从教程中，应该有一段代码：

/ Send Push Notification to all devices
// registered to `my_channel`

JSONObject jso = null;
try {
jso = new JSONObject("{
'aps' : {
'alert' : 'You got your emails.'," + "
'badge' : 9,
'sound' : 'bingbong.aiff'}," + "
'acme 1': 42
}");
pubnub.publish("my_channel", jso,
new Callback(){
@Override
public void successCallback(String arg0,
Object arg1) {
System.out.println(arg1);
}

Sending Notifications
Sending a notification requires creating a JSON object. It is then added to a PubNub GCM specific message (the message is formatted for you).

public void sendNotification() {
    PnGcmMessage gcmMessage = new PnGcmMessage();
    JSONObject jso = new JSONObject();
    try {
        jso.put("GCMSays", "hi");
    } catch (JSONException e) { }
    gcmMessage.setData(jso);

    PnMessage message = new PnMessage(
            pubnub,
            "your channel name",
            callback,
            gcmMessage);
    try {
        message.publish();
    } catch (PubnubException e) {
        e.printStackTrace();
    }
}

Note that we have to create the callback methods which will be fired when the message is published:

public static Callback callback = new Callback() {
    @Override
    public void successCallback(String channel, Object message) {
        Log.i(TAG, "Success on Channel " + CHANNEL + " : " + message);
    }
    @Override
    public void errorCallback(String channel, PubnubError error) {
        Log.i(TAG, "Error On Channel " + CHANNEL + " : " + error);
    }
};

通过实时通道发送数据

如果应用程序已关闭/处于后台，则发送推送通知

来自网站：

/ Send Push Notification to all devices
// registered to `my_channel`

JSONObject jso = null;
try {
jso = new JSONObject("{
'aps' : {
'alert' : 'You got your emails.'," + "
'badge' : 9,
'sound' : 'bingbong.aiff'}," + "
'acme 1': 42
}");
pubnub.publish("my_channel", jso,
new Callback(){
@Override
public void successCallback(String arg0,
Object arg1) {
System.out.println(arg1);
}

Sending Notifications

public void sendNotification() {
    PnGcmMessage gcmMessage = new PnGcmMessage();
    JSONObject jso = new JSONObject();
    try {
        jso.put("GCMSays", "hi");
    } catch (JSONException e) { }
    gcmMessage.setData(jso);

    PnMessage message = new PnMessage(
            pubnub,
            "your channel name",
            callback,
            gcmMessage);
    try {
        message.publish();
    } catch (PubnubException e) {
        e.printStackTrace();
    }
}

Note that we have to create the callback methods which will be fired when the message is published:

public static Callback callback = new Callback() {
    @Override
    public void successCallback(String channel, Object message) {
        Log.i(TAG, "Success on Channel " + CHANNEL + " : " + message);
    }
    @Override
    public void errorCallback(String channel, PubnubError error) {
        Log.i(TAG, "Error On Channel " + CHANNEL + " : " + error);
    }
};

以及：

/ Send Push Notification to all devices
// registered to `my_channel`

JSONObject jso = null;
try {
jso = new JSONObject("{
'aps' : {
'alert' : 'You got your emails.'," + "
'badge' : 9,
'sound' : 'bingbong.aiff'}," + "
'acme 1': 42
}");
pubnub.publish("my_channel", jso,
new Callback(){
@Override
public void successCallback(String arg0,
Object arg1) {
System.out.println(arg1);
}

public void sendNotification() {
    PnGcmMessage gcmMessage = new PnGcmMessage();
    JSONObject jso = new JSONObject();
    try {
        jso.put("GCMSays", "hi");
    } catch (JSONException e) { }
    gcmMessage.setData(jso);

    PnMessage message = new PnMessage(
            pubnub,
            "your channel name",
            callback,
            gcmMessage);
    try {
        message.publish();
    } catch (PubnubException e) {
        e.printStackTrace();
    }
}

Note that we have to create the callback methods which will be fired when the message is published:

public static Callback callback = new Callback() {
    @Override
    public void successCallback(String channel, Object message) {
        Log.i(TAG, "Success on Channel " + CHANNEL + " : " + message);
    }
    @Override
    public void errorCallback(String channel, PubnubError error) {
        Log.i(TAG, "Error On Channel " + CHANNEL + " : " + error);
    }
};

所以，很明显，这是两段不同的代码，它们都没有涵盖这两个选项（应用程序打开时的实时频道，应用程序关闭时的推送通知）

我需要一段代码：

如果应用程序已打开-通过通道发送数据

如果应用程序关闭/在后台-发送推送通知

PubNub移动推送通知 发布者不知道或不关心订阅服务器在设备上是活动（前台）还是非活动（后台或根本不运行-终止状态）。Publisher始终使用GCM（可能还有APNS）负载发布消息

• 活动应用程序将同时接收这两个消息，并阻止通过操作系统的推送消息接收器侦听器显示推送通知
• 非活动应用程序将只接收推送通知并显示该通知。当最终用户点击推送消息时，它将打开应用程序，您可以在其中获取错过的消息，并在应用程序的UI中显示完整内容
