How to use the library PushSharp to send push notifications to iOS? - apple-push-notifications

I am using the latest PushSharp version to send push notification through APN. I am using the below code given in their Git wiki page to send the notifications:
// Configuration (NOTE: .pfx can also be used here)
var config = new ApnsConfiguration (ApnsConfiguration.ApnsServerEnvironment.Sandbox,
"push-cert.p12", "push-cert-pwd");
// Create a new broker
var apnsBroker = new ApnsServiceBroker (config);
// Wire up events
apnsBroker.OnNotificationFailed += (notification, aggregateEx) => {
aggregateEx.Handle (ex => {
// See what kind of exception it was to further diagnose
if (ex is ApnsNotificationException) {
var notificationException = (ApnsNotificationException)ex;
// Deal with the failed notification
var apnsNotification = notificationException.Notification;
var statusCode = notificationException.ErrorStatusCode;
Console.WriteLine ($"Apple Notification Failed: ID={apnsNotification.Identifier}, Code={statusCode}");
} else {
// Inner exception might hold more useful information like an ApnsConnectionException
Console.WriteLine ($"Apple Notification Failed for some unknown reason : {ex.InnerException}");
}
// Mark it as handled
return true;
});
};
apnsBroker.OnNotificationSucceeded += (notification) => {
Console.WriteLine ("Apple Notification Sent!");
};
// Start the broker
apnsBroker.Start ();
foreach (var deviceToken in MY_DEVICE_TOKENS) {
// Queue a notification to send
apnsBroker.QueueNotification (new ApnsNotification {
DeviceToken = deviceToken,
Payload = JObject.Parse ("{\"aps\":{\"badge\":7}}")
});
}
// Stop the broker, wait for it to finish
// This isn't done after every message, but after you're
// done with the broker
apnsBroker.Stop ();
The confusions -
I don't know if the method apnsBroker.QueueNotification sends the push at all, or just queues it up.
I don't know if I need to install the apple certificate in some way on my Windows machine.
There is no proper sample code available online with the latest version of PushSharp.

Just fire the above code in a console application and Pushsharp will send the notifications.
Apple allow a single push token for a push notification at a time.

The code works as it. But there are some uncertain points as you said.
First notification will be send right away when you queue it, it is just a async mechanism to not to wait the code there. So if anything goes wrong (or right) you can handle it via broker's events.
Second part is a little complicated. First of all you have create a certificate for pushnotifications on a macOS machine. Than you have to upload it to your developer account etc. You can find videos how to that via google. It is pretty long to describe it here. Than you have to export your "Apple Push Services" certificate from your macOSmachine to a p12 file. And get and put that .p12 file to your .net service folder for example to "App_Data" folder and load it like (i assume you are writing a web service):
var config = new ApnsConfiguration(ApnsConfiguration.ApnsServerEnvironment.Sandbox,
Path.Combine(HostingEnvironment.ApplicationPhysicalPath, "App_Data", "yourfileName.p12"),"yourFilePassword");
I hope that helps you.

nativescript-phone prevents Nativescript-contacts from returning

I have an app where I want to select a person from contacts and then send a text to that person. It works as expected for the first user, but after that the app never receives control after the contact is selected. I've isolated the problem to the Nativescript-phone plugin. If you simply call phone.sms() to send a text, and then call contacts.getContact(), the problem occurs. I see this on both Android and iOS.
I've created a sample app that demos the problem at https://github.com/dlcole/contactTester. The sample app is Android only. I've spent a couple days on this and welcome any insights.
Edit 4/21/2020:
I've spent more time on this and can see what's happening. Both plugins have the same event handler and same request codes:
nativescript-phone:
var SEND_SMS = 1001;
activity.onActivityResult = function(requestCode, resultCode, data) {
nativescript-contacts:
var PICK_CONTACT = 1001;
appModule.android.on("activityResult", function(eventData) {
What happens is that after invoking phone.sms, calling contacts.getContact causes control to return to the phone plugin, and NOT the contacts plugin. I tried changing phone's request code to 1002 but had the same results.
So, the next step is to determine how to avoid the collision of the event handlers.
Instead of using activityResult event, nativescript-phone plugin overwrites the default activity result callback.
A workaround is to set the callback to it's original value after you are done with nativescript-phone.
exports.sendText = function (args) {
console.log("entering sendText");
const activity = appModule.android.foregroundActivity || appModule.android.startActivity;
const onActivityResult = activity.onActivityResult;
permissions.requestPermissions([android.Manifest.permission.CALL_PHONE],
"Permission needed to send text")
.then(() => {
console.log("permission granted");
phone.sms()
.then((result) => {
console.log(JSON.stringify(result, null, 4));
activity.onActivityResult = onActivityResult;
})
})
}

Issue with FCM Push Notification Android

I was able to receive push notifications some months ago, a day ago i started to work again on the app now the issue is it's not able to receive push notification. It does provide FCM token but onMessageReceived never gets called also if i try with Postman it gives an error of Mismatchsender ID, but the scenario here is a bit confusing. If i change the package name (after creating new project on console and added new goole-service.json file) it doesn't let me register for FCM token. i've stuck in this situation from last day. can anybody please help? what i'm doing wrong.
Here is implementaion of FCMToken
[Service]
[IntentFilter(new[] { "com.google.firebase.INSTANCE_ID_EVENT" })]
public class MyFirebaseIIDService : FirebaseInstanceIdService
{
const string TAG = "MyFirebaseIIDService";
public override void OnTokenRefresh()
{
var refreshedToken = FirebaseInstanceId.Instance.Token;
Log.Debug(TAG, "Refreshed token: " + refreshedToken);
SendRegistrationToServer(refreshedToken);
}
void SendRegistrationToServer(string token)
{
// Add custom implementation, as needed.
}
}
Here it gives me error if i change my package name to any other,
Error: Java.Lang.IllegalStateException: Default FirebaseApp is not
initialized in this process
try
{
var refreshedToken = FirebaseInstanceId.Instance.Token;
// PushNotificationManager.Initialize(this, false);
} catch(Exception ee)
{
}
I've solved my issue with with customization of FirebaseInitialize after creating new project on Firebase here is my code. But one bad thing is here that when new token gets initialized it never gets called on FirebaseInstanceIdReceiver.
var options = new FirebaseOptions.Builder()
.SetApplicationId("<AppID>")
.SetApiKey("<ApiKey>")
.SetDatabaseUrl("<DBURl>")
.SetStorageBucket("<StorageBucket>")
.SetGcmSenderId("<SenderID>").Build();
var fapp = FirebaseApp.InitializeApp(this, options);

Schedule push notification Parse unity

Can i use Parse.com Unity plugin to schedule push notification to the user once an action is done.
i.e) Notify the user in 1 hour that his building has been built.(as in coc an example)
I don't think Push Notifications is what you are looking for here, instead I think you want Local Notifications. With Local Notifications, you schedule a notification to appear at a specified time (you usually schedule the notification when the player leaves the app, as you wouldn't normally want the notification to appear as they are playing it).
For example, you would do the following (not tested):
public void OnApplicationPause(bool isPaused)
{
// If paused, then in background
if (isPaused)
{
LocalNotification notification = new LocalNotification();
notification.alertAction = "App Name";
notification.alertBody = "The building is complete";
notification.hasAction = true;
notification.applicationIconBadgeNumber = 1; // Set's the badge count
notification.fireDate = dateBuildingWillBeFinished;
NotificationServices.ScheduleLocalNotification(notification);
}
else // Entered the app
{
// Clear notifications
NotificationServices.CancelAllLocalNotifications();
NotificationServices.ClearLocalNotifications();
}
}
Push Notifications are generally used to send messages to all players, or a group of players (such as players in the UK) to notify them of something, like a sale that is going on for in app purchases. Local Notifications are user specific, and can act more as reminders, such as your building has been completed or you haven't visited your town in a week etc.

parse.com Client Push notifications are not received in windows phone when application is offline

I have followed the steps given in the document in parse.com, but the client side notifications are not received in windows phone when the app is offline. But if I send a Campaign push from parse.com it reaches fine even if the app is offline.
The client push works fine if my app is online. Also I have verified that my client push reaches parse.com and do not see any issues with the message content.
public App() {
ParseClient.Initialize("xxxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxx");
this.Startup += async (sender, args) =>
{
// This optional line tracks statistics around app opens, including push effectiveness:
ParseAnalytics.TrackAppOpens(RootFrame);
ParsePush.ToastNotificationReceived += (sender, args) =>
{
var json = ParsePush.PushJson(args);
MessageBox.Show("Received a new notification");
};
}

Wp7:Push notification channel URI is null

We are trying to test push notifications, using the latest code from the documentation How to: Set Up a Notification Channel for Windows Phone
public HttpNotificationChannel myChannel;
public void CreatingANotificationChannel()
{
myChannel = HttpNotificationChannel.Find("MyChannel");
if (myChannel == null)
{
myChannel = new HttpNotificationChannel("MyChannel","www.contoso.com");
// An application is expected to send its notification channel URI to its corresponding web service each time it launches.
// The notification channel URI is not guaranteed to be the same as the last time the application ran.
myChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(myChannel_ChannelUriUpdated);
myChannel.Open();
}
else // Found an existing notification channel.
{
// The URI that the application sends to its web service.
Debug.WriteLine("Notification channel URI:" + myChannel.ChannelUri.ToString());
}
myChannel.HttpNotificationReceived += new EventHandler<HttpNotificationEventArgs>(myChannel_HttpNotificationReceived);
myChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(myChannel_ShellToastNotificationReceived);
myChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(myChannel_ErrorOccurred);
}
If HttpNotificationChannel.Find() returns null, it opens a new channel, but the ChannelUriUpdated event is never triggered.
If HttpNotificationChannel.Find() returns a channel, the ChannelUri property is null. The sample code crashes here because it assumes the ChannelUri property to be not null.
In neither case is the ErrorOccurred event triggered.
How can i solve this problem? This problem is because of microsoft server or any thing else?
Thnks in advance
EDIT
Waiting for replay,after ten days i am suffering of null uri problem
Can any one tell me how can i solve this problem some time MSPN server give chanalk uri ans some time not i mean some time it give null reference Exception.
What Microsoft doing?
If I don't go wrong, www.contoso.com it's a example URI to demonstrate that you need to put your own server URL address, but in my experience, I never use in that way. I prefer just to put
myChannel = new HttpNotificationChannel("MyChannel");
Look this example (it's in Spanish) but the codes are very clear of what you need to do to set the push notification client and service.
I hope I helped you.
You are testing in what mobile are Emulator,
Do you have developer account subscription for windows phone development,
Had you Developer unlocked your mobile,
Noorul.
I think the problem is that you are using the HttpNotificationChannel constructor of the authenticated web service, according to the documentation.
Instead, you should use the constructor that takes only one parameter, as you can check in this example
/// Holds the push channel that is created or found.
HttpNotificationChannel pushChannel;
// The name of our push channel.
string channelName = "ToastSampleChannel";
// Try to find the push channel.
pushChannel = HttpNotificationChannel.Find(channelName);
// If the channel was not found, then create a new connection to the push service.
if (pushChannel == null)
{
pushChannel = new HttpNotificationChannel(channelName);
...
}
Hope it helps
