I installed the in app billing plugin in my Xamarin Forms project: Plugin.
First I want to use it on iOS but the plugin doesn't work. It shows following error: Plugin.InAppBilling.Abstractions.InAppBillingPurchaseException: Cannot connect to iTunes Store
at Plugin.InAppBilling.InAppBillingImplementation.PurchaseAsync (System.String productId, Plugin.InAppBilling.Abstractions.ItemType itemType, System.String payload, Plugin.InAppBilling.Abstractions.IInAppBillingVerifyPurchase verifyPurchase) ..
I think my productId or the payload is wrong, what should I put in there?
Here is my Code:
try
{
var productId = "mySKU";
var connected = await CrossInAppBilling.Current.ConnectAsync();
if (!connected)
{
//Couldn't connect to billing, could be offline, alert user
return;
}
//try to purchase item
var purchase = await CrossInAppBilling.Current.PurchaseAsync(productId, ItemType.Subscription, "payload");
if (purchase == null)
{
//Not purchased, alert the user
}
else
{
//Purchased, save this information
var id = purchase.Id;
var token = purchase.PurchaseToken;
var state = purchase.State;
}
}
catch (Exception ex)
{
Console.WriteLine(ex);
//Something bad has occurred, alert user
}
finally
{
//Disconnect, it is okay if we never connected
await CrossInAppBilling.Current.DisconnectAsync();
}
I hope anybody can help me. Thanks in advance.
I fixed it. For all those who have the same problem: My problem was, that I created a bundle id. Then I activated the automatic signing in Visual Studio and it created another bundle id automatically. I selected it and I had to give it a name. After I clicked save, it changed back to the other id. The problem was that the ids had the same name. So I renamed the bundle id in Visual Studio and it works like a charm.
You must setup ios settings before using that nuget:

I am referring to this blog for listing the phone contacts. It is working fine on the ios part but on android part, the contacts are not listing. There are no exceptions or errors but the UI is blank.
As per the blog I have done the below things on the android platform:
created the model class Contact and interface IContactsService.
Added READ_CONTACTS permission and added ContactsService implementation.
Installed Plugin.CurrentActivity and Acr.UserDialogs packages.
Added Permission.Util class into the Android project.
Added required things on the MainActivity and ContactPage files on the Main project.
Don't know what I am missing on the android part, on ios it is working fine. On android, the contact permission is not asking during runtime. I manually add the permission from the app settings, but no luck. My Xamarin forms version: 4.8.0.1821
I am uploading a sample project here for reference.
Thanks in advance.
Got the answer from my Microsoft QA thread:
Android 10 does not use Android.Support.V4.Content.ContextCompat to request permission, so please use Xamarin.Essentials: Permissions to request runtime permission.
On ContactsViewModel.cs, add CheckAndContactsReadPermission()method in LoadContacts method like following code.
async Task LoadContacts()
{
try
{
await CheckAndContactsReadPermission();
await _contactService.RetrieveContactsAsync();
}
catch (TaskCanceledException)
{
Console.WriteLine("Task was cancelled");
}
}
public async Task<PermissionStatus> CheckAndContactsReadPermission()
{
var status = await Permissions.CheckStatusAsync<Permissions.ContactsRead>();
if (status == PermissionStatus.Granted)
return status;
if (status == PermissionStatus.Denied && DeviceInfo.Platform == DevicePlatform.iOS)
{
// Prompt the user to turn on in settings
// On iOS once permission has been denied it may not be requested again from the application
return status;
}
status = await Permissions.RequestAsync<Permissions.ContactsRead>();
return status;
}
On ContactsService.cs, change the LoadContactsAsync method like the following code.
async Task<IList<Contact>> LoadContactsAsync()
{
IList<Contact> contacts = new List<Contact>();
//var hasPermission = await RequestPermissionAsync();
//if (hasPermission)
//{
var uri = ContactsContract.Contacts.ContentUri;
var ctx = Application.Context;
await Task.Run(() =>
{
var cursor = ctx.ApplicationContext.ContentResolver.Query(uri, new string[]
{
ContactsContract.Contacts.InterfaceConsts.Id,
ContactsContract.Contacts.InterfaceConsts.DisplayName,
ContactsContract.Contacts.InterfaceConsts.PhotoThumbnailUri
}, null, null, $"{ContactsContract.Contacts.InterfaceConsts.DisplayName} ASC");
if (cursor.Count > 0)
{
while (cursor.MoveToNext())
{
var contact = CreateContact(cursor, ctx);
if (!string.IsNullOrWhiteSpace(contact.Name))
{
OnContactLoaded?.Invoke(this, new ContactEventArgs(contact));
contacts.Add(contact);
}
if (stopLoad)
break;
}
}
});
// }
return contacts;
}
I'm currently trying to get push notifications working for my mobile app using Azure Notification Hubs. Android is working fine and the initial iOS set up in AppDelegate works ok with a sample tag.
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
if (deviceToken == null)
{
return;
}
SBNotificationHub hub = new SBNotificationHub(CommonConstants.LISTEN_CONNECTION_STRING, CommonConstants.NOTIFICATION_HUB_NAME);
// update registration with Azure Notification Hub
hub.UnregisterAll(deviceToken, async (error) =>
{
if (error != null)
{
System.Diagnostics.Debug.WriteLine($"Unable to call unregister {error}");
return;
}
string[] tags = new[] { "iostestpush" };
NSSet userTags = new NSSet(tags);
hub.RegisterNative(deviceToken, userTags, (error) =>
{
if (error != null)
{
System.Diagnostics.Debug.WriteLine($"Unable to call register {error}");
return;
}
});
var templateExpiration = DateTime.Now.AddDays(120).ToString(System.Globalization.CultureInfo.CreateSpecificCulture("en-US"));
hub.RegisterTemplate(deviceToken, "defaultTemplate", CommonConstants.APN_TEMPLATE_BODY, templateExpiration, userTags, (errorCallback) =>
{
if (errorCallback != null)
{
System.Diagnostics.Debug.WriteLine($"RegisterTemplateAsync error: {errorCallback}");
}
});
});
}
The issue I'm having is I need to register the UserId after a successful login. So I set up a service with the above code, saved the token to the device as string so it can be retrieved in the service and turned back into an NSData token
NSData deviceToken = new NSData(token, NSDataBase64DecodingOptions.None);
After a successful login I send the token string and the tag array to my service.
string[] userTag = new[] { loginResponse.UserId.ToString() };
await this._azureReg.SendRegistrationToServer(deviceToken, userTag);
Which, other than turning the token back into NSData and the user tag into an NSSet, is the same as above other than the name change. But Azure is claiming there is no registration even though my output shows
Registered for push notifications with token: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
I thought it was the string conversion back and forth, so tested that in the AppDelegate and it worked fine.
So, I'm at a loss at how to register the UserId after a successful login and why it works in one place but not the other.
I hope that's clear and thanks for any advice in advance.
You probably ran into the same bug as me and several others.
Basically SBNotificationHub method overloads like UnregisterAll and RegisterTemplate with the callback signature do not work when you use them off the main thread, using the libraries to date. I was also using a Service for the same purpose (to handle push across platforms with different tags, especially for user id) but my implementation involved switching off the main thread for this.
The bug we logged and is now being addressed is here: https://github.com/Azure/azure-notificationhubs-ios/issues/95
The solution, for now, is to ditch SBNotificationHub completely. The Xamarin / Azure documentation is out of date, and SBNOtificationHub is legacy code. The recommended library is MSNotificationHub. https://github.com/azure/azure-notificationhubs-xamarin
As workarounds you can use the SBNotificationHub method overloads that do not involve callbacks (they return an error message instead) or the workaround in the 95 issue above.
I have a Xamarin.Forms application supporting Android, iOS, and UWP. I need the application at the starting point to check if location feature is enabled, and if not, suggest the user to do so, and let him open device Settings. But if the user agrees to open the Settings, I would need the application to wait for the results, and then continue based on the newly changed settings. But how can I make the execution wait for the user to finish working with the settings?
Here is the code I have for now:
Task<bool> task = Application.Current?.MainPage?.DisplayAlert("Location service is disabled on this device",
"MyCompany Mobile uses your location to provide you with the correct product mix and other information for your market. Please go into Settings and turn on Location for the device.",
"Settings",
"Maybe Later");
if (task == null)
{
return bu;
}
bool result = await task;
if (result)
{
IDeviceService deviceService = DependencyService.Get<IDeviceService>();
if (deviceService != null)
{
bool openedSuccessfully = await deviceService.OpenDeviceSettingsAsync();
}
}
I am sending app usage analytics events to Fabric and Firebase. Together with the event, I am also sending another value (an example event type is font_selection and the value I pass is which font the user selects - this is a number that tells me which font was used). I was using Fabric events and I could see which fonts were being used more or less when I selected the font_selection event (I could see numbers for each different font).
Since the Fabric functionality is being moved to Firebase, I started checking the Analytics section in Firebase. Unfortunately I cannot find the above information in Firebase > Analytics > Events. I can see the event, font_selection but when I click on it I do not get the additional information I used to get in Fabric. Is there something I am missing or has this additional information been removed from Firebase?
This is still an issue for me. Here is how I'm sending the event into Firebase:
protected void Report(string id, Severity severity, string message = null, Exception exception = null)
{
try
{
var processedId = id ?? severity.ToString().ToLowerInvariant();
var values = new Dictionary<string, string>();
values.Add("severity", severity.ToString().ToLowerInvariant());
if (!string.IsNullOrWhiteSpace(message))
{
values.Add("message", message);
}
if (exception != null)
{
values.Add("exception", exception.Message);
values.Add("trace", exception.StackTrace);
}
SendEvent(values, processedId);
}
catch
{
// do nothing.
}
}
protected override void SendEvent(Dictionary<string, string> eventData, string id)
{
var firebaseAnalytics = FirebaseAnalytics.GetInstance(Android.App.Application.Context);
var bundle = new Android.OS.Bundle();
foreach(var pair in eventData)
{
bundle.PutString(pair.Key, pair.Value);
}
firebaseAnalytics.LogEvent(id, bundle);
}
During runtime, I call this successfully and I can see these event popping up in Firebase console:
But how do I display the rest of the properties that I have bundled with it? Here is what the console shows me in events:
I feel like I must be using it wrong or something. There is no UI to shows me a simple chronologically sorted table with events as they came in with properties they came with. I frankly don't understand what good is this tool to me.
I have two IAPs set up on for my iOS app on iTunes Connect. All of the information is in there and they marry up to what I have set for Android. On iTunes, they are set as non-renewing subscriptions (mainly as this is what the review said they should be). There are no errors shown on the IAP screen and have been submitted for review (this makes no difference, the ones I had there previously didn't show either)
I'm using the Xamarin In App Purchase nuget package to get this working. When I run the app on Android, the packages show correctly. When I run the same code on iOS, nothing is showing.
I have a user set on the sandbox and have followed the instructions on the iTunes website on logging out of the store, but I'm seeing nothing - it's not even asking me to log into the store.
My code for interrogating the store is this
async Task<List<InAppBillingProduct>> GetItems()
{
var billing = CrossInAppBilling.Current;
try
{
var productIds = new string[] { "monthly_renewals", "yearly_subscriptions" };
//You must connect
var connected = await billing.ConnectAsync();
if (!connected)
{
//Couldn't connect
return new List<InAppBillingProduct>();
}
//check purchases
var items = await billing.GetProductInfoAsync(ItemType.Subscription, productIds);
return items.ToList();
}
catch (InAppBillingPurchaseException)
{
return new List<InAppBillingProduct>();
}
catch (Exception)
{
return new List<InAppBillingProduct>();
}
finally
{
await billing.DisconnectAsync();
}
}
It makes no difference if I set the ItemType to Subscription or InAppPurchase. All of the licences on iTunesConnect are correct, IAP is set to work in the provisioning profile too.
Given the store isn't asking for a login for the sandbox user, I'm wondering if something else needs to be done - I just don't know what.
