Hi all,
When I double-click my Xamarin Studio shortcut, or XamarinStudio.exe in C:\Program Files\Xamarin Studio\bin\XamarinStudio.exe, nothing happens apart from the mouse cursor flickering to busy and back again.
According to the exe properties, I've got version 4.0.0.0
I'm running Windows 7 32 bit.
Any thoughts/pointers?
Thanks,
James
I am seeing a strange error, I currently have 2 feature files in my project
When I send the test project up to test cloud with the tag "--include Filters", it works fine but when I send it up with "--include Login" the submission is rejected as it was unable to find any tests associated with this tag and I get the following error.
_C:\Users\Brian.Mitchell>test-cloud.exe submit E:\Projects\GEMApp\gemapp\GemApp.M
anagerApp\GemApp.ManagerApp.Droid\bin\Debug\hgem.manager.apk --devices 37bc9d06 --series "Alpha" --category Login --locale "en
_GB" --user brian.mitchell@hgem.com --assembly-dir E:\Projects\GEMApp\gemapp\GemApp.ManagerApp.UITests\bin\Debug
No tests would be run in Xamarin Test Cloud, reasons:
Filtered.: GemApp.ManagerApp.UITests.Features.Filters.FiltersFeature(Android).ApplyASingleBranchFilter, GemApp.ManagerApp.UITests.Features.Filters.FiltersFeature(Android).ApplyASinglePeriodFilter, GemApp.ManagerApp.UITests.Features.Filters.
FiltersFeature(Android).ApplyMultipleBranchFilters, GemApp.ManagerApp.UITests.Features.Filters.FiltersFeature(Android).ApplyMultiplePeriodFilters, GemApp.ManagerApp.UITests.Features.Filters.FiltersFeature(Android).ResetFilter, GemApp.ManagerApp.UITests.Features.Login.LoginFeature(Android).LoginWithCorrectDetails, GemApp.ManagerApp.UITests.Features.Login.LoginFeature(Android).LoginWithIncorrectDetails, GemApp.ManagerApp.UITests.Features.Login.LoginFeature(Android).LoginWithIncorrectPassword, GemApp.ManagerApp.UITests.Features.Login.LoginFeature(Android).LoginWithIncorrectUsername, GemApp.ManagerApp.UITests.Features.Login.LoginFeature(Android).LoginWithNoDetails, GemApp.ManagerApp.UITests.Features.Login.LoginFeature(Android).LogoutOfApp
_
It seems off as the 2 feature files were created in the same manner and are in the same project.
I am not sure why it works fine with one and not the other.
I am getting the following error whem buiding...
/Volumes/MacBook Pro Backup 1/Xamarin/NSE/iOS/NSE.iOS.csproj(3,3): Error MSB4019: The imported project "/Library/Frameworks/Mono.framework/Versions/4.8.0/lib/mono/xbuild/Xamarin/iOS/Xamarin.iOS.CSharp.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk. (MSB4019) (NSE.iOS)
The path mentioned in the error does not exist. The is no Xamarin directory under xbuild.
This worked fine before upgrading to Preview 4. I even uninstalled Visual Studio and the Mono Framework and reinstalled it.
I assume it is complaining about the following line in my NSE.iOS.csproj file...
I am using Xamarin ios designer. It works fine to add constraints in table view cell when the table view is set to dynamic mode. While, with the static mode, the designer cannot present any layout constraints. It is very strange. Is it due to some bugs of the ios designer? By the way, I am using storyboard.
Hi! I'm trying to upload photo to server but i'm getting exceptions on both android and ios. Exceptions don't occurred everytime but very often.
This is the method where i'm trying to upload:
`
public async Task UploadImage(string assignmentId, string title, Stream imageStream)
{
if (imageStream == null)
return new ImageUploadResponse { Success = false, Message = "Unexpected error has occurred, image doesn't exist" };
var checkForToken = await CheckIsTokenValid();
if (!checkForToken)
return new ImageUploadResponse { Success = false, Message = _errorCommunicatingWithServer };
var filename = (title + ".jpg").Replace(' ', '_');
var url = $"{URL_Base}/uploadimage";
var multipartFormContent = new MultipartFormDataContent
{
{new StringContent(assignmentId), "Id"},
{new StringContent(title), "Title"}
};
var scontent = new StreamContent(imageStream);
scontent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data");
scontent.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");
multipartFormContent.Add(new StreamContent(imageStream), "filename", title + ".jpg");
var data = string.Empty;
try
{
HttpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer",
Settings.Token);
var responseMessage = await HttpClient.PostAsync(url, multipartFormContent);
var responseContent = await responseMessage.Content.ReadAsStringAsync();
if (responseMessage.IsSuccessStatusCode)
{
return JsonConvert.DeserializeObject<ImageUploadResponse>(responseContent);
}
}
catch (Exception e)
{
Rollbar.Current.Report(new Exception(data, e), ErrorLevel.Error);
return new ImageUploadResponse { Success = false, Message = e.Message };
}
return new ImageUploadResponse { Success = false, Message = _errorCommunicatingWithServer };
}
`
Error on iOS is:
System.Net.WebException: The network connection was lost.
Traceback (most recent call last):
Foundation.NSErrorException: Exception of type 'Foundation.NSErrorException' was thrown.
and on Android:
Java.IO.IOException: Write error: ssl=0xaf030da0: I/O error during system call, Connection reset by peer
Do you have any idea?
Thanks

A virtualized collection view that utilizes native layout controls to present an ordered set of data items using a flexible and changeable layout. The portable control must be bindable, support item templating and (optionally) support section headers.
Platform renderers would be based on the following native controls:

The most common use would be to present items in a grid arrangement, although the control could be configurable to present items as a vertical or horizontal list. The control is intended for applications where a bindable, virtualized collection view layout is required that is not served by any of the existing Xamarin.Forms controls.

Hi guys i am having serious issues publishing my application and installing it as a apk file. I have followed the guide of preparing an application for release
http://docs.xamarin.com/guides/android/deployment,testing,_and_metrics/publishing_an_application/part_1-_preparing_an_application_for_release/
The application works fine when debugging on the device but for some reason the apk that i install always crashes.
Attached is my logcat, if anyone could possibly help I would greatly appreciate it
It looks to be somewhere around these lines, but i have no idea what it means
UNHANDLED EXCEPTION: System.NotSupportedException: CodePage 1252 not supported

Hi all,
Does anyone know what to do? This error only occur in the IOS version of my xamarin.forms project.
Everything was running fine until I installed nuget package for WindowsAzure.MobileServices (Microsoft.Bcl,Microsoft.Bcl.Build,Microsoft.Net.Http)
Even If I remove those packages, I've got this error...
Using Xamarin.UITests app.screenshot is great in UITests.
I was wondering how it was possible to take part of part of the screen.
The reason for this is take screenshots of graphs and do a pixel comparison on it. so I will need to grab a particular part of the screen.
Is there a way I can pass in some coordinates or something like that?
I am developing a GTK# application and I experience a problem when attempting to develop between Linux and Windows.
After a while, I always get the following run-time error when launching the debugger in Xamarin Studio on Windows:
I have checked the project as much as I can and as far as I can tell it shouldn't be looking for version 2.0-0 of libglib:
Is anyone here able to shed some light on this error? The only way around it I've found so far is to start a new project in Xamarin Studio and then copy all my source code and classes over!
Cheers,
Brian
can be found at mono/Ping.cs (line 339)
That calls the system ping command and checks the exit code:
if (!ping.WaitForExit (timeout) || (ping.HasExited && ping.ExitCode == 2))
status = IPStatus.TimedOut;
else if (ping.ExitCode == 0)
status = IPStatus.Success;
else if (ping.ExitCode == 1)
status = IPStatus.TtlExpired;
So TTL expired is set when there was no timeout, no error or success (exit code 2 or 0), and the exit code was 1.
If ping does not receive any reply packets at all it will exit with code 1. If a packet count and deadline are both specified, and fewer than count packets are received by the time the deadline has arrived, it will also exit with code 1. On other error it exits with code 2. Otherwise it exits with code 0. This makes it possible to use the exit code to see if a host is alive or not.
So a return value of 1 indicates that no response has been received (for various reasons) and the Mono implementation sets the TTL expired status in this case. I would expect that a time out status would be returned in such cases. But it seems that the timeout detection of the Mono implementation is not triggered here (e.g. because the ping command exits upon on it's own timeout before).
So there are two other possible solutions:
To treat a TTL expired as host not alive (but this will then ignore ignore real TTL expired detections)
Please fix ASAP this is very very annoying . It should be there a IPStatus for :
Destination Host Unreachable , Timeout , Destination Network Unreachable and ect ....
Hi,
I have random HTML content coming from service which I am displaying in a webview in a xamarin forms application. Now, I want to adjust the height of this webview as per the content.
Currently I am setting the height based on the length of HTML but it does not give correct results.
Can you suggest an alternate way to achieve the same?
Thanks
Deepesh.
HI Guys
We are deploying an enterprise app as the last leg of our development and we are getting a really strange error that does not let the app to install on a device. it goes to 80% and it disappears.
We made sure bundle id is correct on both the solution settings, provisioning profile is imported to xcode and selected in xamarin settings. however, when creating the app id, by default we see in-app purchases and game center enabled which we can not change. in the app log, we get some type of entitlement error.
not sure if anyone came across this and whether there is a workaround for this, for a week now we ve been banging our heads trying the steps over and over (creating different profiles, editing them, import delete etc but with no luck)
i have attached a log file, maybe someone came across a solution.
Thanks,
is there a way to prompt the user/pass and get file access etc..
i need to write files and create launch daemon but i need root privileges for doing it
Hi everyone,
How can I design a menu item like Youtube app as below screenshots
I'm using Content Pages embed in a Tabbed Page as below code
<?xml version="1.0" encoding="utf-8" ?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="TestApp"
xmlns:pages="clr-namespace:TestApp;assembly=TestApp"
Title="Hello">
<ContentPage Title="Tab 1">
<ContentPage.ToolbarItems>
<ToolbarItem Name="MenuItem1" Order="Primary" Icon="Microsoft.png" Text="Item 1" Priority="0" />
<ToolbarItem Name="MenuItem2" Order="Secondary" Icon="Xamarin.png" Text="Item 2" Priority="1" />
</ContentPage.ToolbarItems>
</ContentPage>
<ContentPage Title="Tab 2">
<ContentPage.ToolbarItems>
<ToolbarItem Name="MenuItem1" Order="Primary" Icon="Microsoft.png" Text="Item 1" Priority="0" />
<ToolbarItem Name="MenuItem2" Order="Secondary" Icon="Xamarin.png" Text="Item 2" Priority="1" />
</ContentPage.ToolbarItems>
</ContentPage>
</TabbedPage>
I don't know whether this approach is correct? Is there any other approach better than this one?

Another question: With kind of this UI should I go with xamarin.forms or native?
