即使应用处于闲置状态或处于后台，我们如何在phonegap android应用中获取GCM 推送通知。
“ katzer / cordova-plugin-background-mode”似乎不起作用...
“ 当应用程序运行在前台时，我成功获得了推送通知 ”
科尔多瓦版本：4.3.0 android 4.4 phonegap 4.2.0
我会复制下面我通知功能......上deviceready
函数onDeviceReady（）{
try
{
pushNotification = window.plugins.pushNotification;
jQuery("#app-status-ul").append('<li>registering ' + device.platform + '</li>');
if (device.platform == 'android' || device.platform == 'Android' ||
device.platform == 'amazon-fireos' ) {
pushNotification.register(successHandler, errorHandler, {"senderID":"my-project-id","ecb":"onNotification"});
} else {
pushNotification.register(tokenHandler, errorHandler, {"badge":"true","sound":"true","alert":"true","ecb":"onNotificationAPN"}); // required!
}
}
catch(err)
{
txt="There was an error on this page.\n\n";
txt+="Error description: " + err.message + "\n\n";
alert(txt);
}
}
和
函数onNotification（e）{
switch( e.event )
{
case 'registered':
if ( e.regid!='' )
{
android_reg_id = e.regid;
jQuery.ajax({
type:"POST",
url:SITEURL+"index.php?r=Manageuser/App_Reg_Android",
data:{regid: android_reg_id,employeeno:employeeno}
}).done(function(msg) {
});
}
break;
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)
{
//jQuery("#app-status-ul").html('<li>MESSAGE -> MSG: ' + e.payload.message + '</li>');
// on Android soundname is outside the payload.
// On Amazon FireOS all custom attributes are contained within payload
var soundfile = e.soundname || e.payload.sound;
// if the notification contains a soundname, play it.
// playing a sound also requires the org.apache.cordova.media plugin
var my_media = new Media("/www/"+ soundfile);
my_media.play();
}
else
{
if (e.coldstart)
$("#app-status-ul").append('<li>--COLDSTART NOTIFICATION--' + '</li>');
else
$("#app-status-ul").append('<li>--BACKGROUND NOTIFICATION--' + '</li>');
//location.href = e.payload.redid;
// otherwise we were launched because the user touched a notification in the notification tray.
}
jQuery("#app-status-ul").html('<li>MESSAGE -> MSG: ' + e.payload.message + '</li>');
//window.localStorage.setItem("push_que", e.payload.redid);
//location.href = e.payload.redid;
break;
case 'error':
jQuery("#app-status-ul").append('<li>ERROR -> MSG:' + e.msg + '</li>');
break;
default:
jQuery("#app-status-ul").append('<li>EVENT -> Unknown, an event was received and we do not know what it is</li>');
break;
}
}
使用的插件是com.phonegap.plugins.PushPlugin 2.4.0“ PushPlugin”
我不确定您使用哪个插件来捕获推送通知，但我建议您使用phonegap-build/PushPlugin。它有一个处理程序，可以在应用程序打开、在后台或关闭时捕获通知。如果您按通知，它将打开您的应用程序。
要使用该插件，只需将其放入您的代码中：
var pushNotification;
document.addEventListener("deviceready", function(){
pushNotification = window.plugins.pushNotification;
if ( device.platform == 'android' || device.platform == 'Android' ){
pushNotification.register(
successHandler,
errorHandler,
{
"senderID":"replace_with_sender_id",
"ecb":"onNotification"
});
}
//the rest of your deviceReady function
});
// result contains any message sent from the plugin call
function successHandler (result) {
alert('result = ' + result);
}
// result contains any error description text returned from the plugin call
function errorHandler (error) {
alert('error = ' + error);
}
现在我们已经将插件的实例设置为全局变量pushNotification和一个 if 语句，该语句将您的 Android 设备注册到 GCM 服务，但您需要将 Google API 项目的 senderID 放在这里："senderID":"replace_with_sender_id"。如果设备注册成功，它将调用该函数onNotification。该函数应该执行如下操作：
function onNotification(e) {
console.log('event received: '+e.event);
switch( e.event )
{
case 'registered':
if ( e.regid.length > 0 )
{
//Here you should call a function that sends the registration-ID
//to your server so you can save it and send push notifications to your device
console.log("regID = " + e.regid);
}
break;
case 'message':
if ( e.foreground )
{
//App was open when the notification was received
console.log('foreground');
// on Android soundname is outside the payload.
var soundfile = e.soundname || e.payload.sound;
// if the notification contains a soundname, play it.
var my_media = new Media("/android_asset/www/"+ soundfile);
my_media.play();
}
else
{
if ( e.coldstart )
{
//App was closed
console.log('coldstart');
}
else
{
//App was open in the background
console.log('background');
}
}
alert('message: '+e.payload.message);
break;
case 'error':
alert('GCM error: '+e.msg);
break;
default:
alert('An unknown event has occurred');
break;
}
}
该函数从 GCM 服务接收一个事件，该事件告诉它要做什么。如果设备已注册，它会在控制台中记录设备注册 ID，如果收到消息，它会检查应用程序是否打开、关闭或在后台打开，并会提醒该消息alert('message: '+e.payload.message);。
由于您使用的是 Android，所以我刚刚包含了 Android 的代码。我希望这就是您正在寻找的。
