Cannot enable AppCenter.Crashes on Xamarin.iOS app

1.5k Views Asked by j-guyon At 13 March 2018 at 17:49

Trying to use the new AppCenter on an existing Xamarin.iOS application, i have some trouble with the AppCenter.Crashes API.

I follow the Get started section and add following code in my AppDelegate.cs :

using Microsoft.AppCenter;
using Microsoft.AppCenter.Analytics;
using Microsoft.AppCenter.Crashes;

// ...
public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
    //...
    // App Center
    AppCenter.Start("xxxxxxx-xxxx-xxxx-xxxx", typeof(Analytics), typeof(Crashes));

    return true;
}

I also installed corresponding NuGet packages (here is corresponding line in my packages.config)

<package id="Microsoft.AppCenter" version="1.5.0" targetFramework="xamarinios10" />
<package id="Microsoft.AppCenter.Analytics" version="1.5.0" targetFramework="xamarinios10" />
<package id="Microsoft.AppCenter.Crashes" version="1.5.0" targetFramework="xamarinios10" />

Note that If i disable the AppCenter.Crashes module :

AppCenter.Start("xxxxxxx-xxxx-xxxx-xxxx", typeof(Analytics));

Everything is fine (and i can see Analytics in the App center back-end)

But with the AppCenter.Crashes module enable, my app crash with the following message in console :

Last logs are repeated from 1.mscrasheslogbuffer to 59.mscrasheslogbuffer

Note that my app loading follow this steps :

Loading a first viewController with an image, an activity indicator whitch calls some Rest API
After API calls perform a segue to another ViewController with a NavBar

App seems crash between the two step : I can see the first screen and log indicate that the http/api stuff is OK.

Note that i have the same behavior on a simulator and a real device.

Any ideas ?

Edit 1 : Add more logs with AppCenter.LogLevel = LogLevel.Verbose;

We had the same problem on our side too.

We resolved it by removing the nuget reference to Microsoft.AppCenter.

In other words, we only kept the nuget references to

Microsoft.AppCenter.Analytics
Microsoft.AppCenter.Crashes

We are using version 1.5.0 as well.
