Description Matthew Robbins 2015-03-03 21:45:01 UTC
When providing a Java.IO.IOException to Xamarin.Insights via Report(...), the application will permanently lock while it attempts to serialise the exception.

This causes extremely serious unexpected behaviour; I've experienced this causing both a deadlock and an ANR.

The bug occurs in Insights version 1.8.2 and earlier.

This small sample reproduces the issue:
namespace InsightsCrash
{
	[Activity (Label = "InsightsCrash", MainLauncher = true, Icon = "@drawable/icon")]
	public class MainActivity : Activity
	{
		int count = 1;

		protected override void OnCreate (Bundle bundle)
		{
			base.OnCreate (bundle);

			// Set our view from the "main" layout resource
			SetContentView (Resource.Layout.Main);

			// Get our button from the layout resource,
			// and attach an event to it
			Button button = FindViewById<Button> (Resource.Id.myButton);
			
			button.Click += delegate {

				try {
					Java.IO.File f = new Java.IO.File("borkeded/file.path");
					Java.Lang.StringBuilder sb = new Java.Lang.StringBuilder();
					Java.IO.BufferedReader br = new Java.IO.BufferedReader(new Java.IO.FileReader(f));
					br.ReadLine();
					br.Close();
				} catch (Java.IO.IOException ex) {

					const string ANALYTICS_INSIGHTS_APIKEY_DEVELOPMENT 	= "my-key";
					Xamarin.Insights.Initialize(ANALYTICS_INSIGHTS_APIKEY_DEVELOPMENT, this.BaseContext);
					Xamarin.Insights.Report (ex);
				}
			};
		}
	}
