Android app sometimes crashing with Java.Net.SocketException #153
Comments
|
Hm, looks like we're not marshaling an exception properly |
|
Same seems to happen with a "Java.Net.ConnectException". Is there anything I can do to help you? |
|
Line numbers in this call stack would help :) |
|
I can reproduce this consistently on 5.0, I can't seem to make it happen on earlier versions. ModernHttpClient is 2.4.2. I'm not sure this is an issue though, for me its the result of cancelling a task that is a request. |
|
|
@dbeattie71 Can you get line numbers for the original call stack? |
|
Sorry I couldn't provide you with the linenumbers. |
|
Still getting sometimes exceptions in my dashboard which aren't getting caught by my try/catch |
|
I was hoping to transition to ModernHttpClient to leverage its performance but also to address a problem we're seeing with the .net HttpClient. However, when testing we frequently ran into this issue, and having the app crash due to a network error is obviously a non-starter. I will try to find time to capture a stack trace and add it to this bug, if that helps. |

Hi, guys Just to throw in the information I have: We wrote an application and were having similar problems: some users reported that requests didn't finish - but just on some devices ... same as you guys here. Now I got hands on one of those mobile-phones. It was a I wonder if it has something to do with this one ... https://stackoverflow.com/questions/30312571/socketexception-socket-closed-only-with-motorola-moto-g-2013 - maybe also a false positive. If you need some further testing, I am willing to ask the guy, owning that phone, for a visit to do further testing. |

To prevent Xamarin.Android from crashing (and allow me to catch network errors) I needed to add this to my [Application]
public class MyApplication : Application
{
public MyApplication(IntPtr javaReference, JniHandleOwnership transfer) : base(javaReference, transfer) { }
public override void OnCreate()
{
base.OnCreate();
AndroidEnvironment.UnhandledExceptionRaiser += OnAndroidEnvironmentUnhandledException;
}
protected override void Dispose(bool disposing)
{
AndroidEnvironment.UnhandledExceptionRaiser -= OnAndroidEnvironmentUnhandledException;
base.Dispose(disposing);
}
private void OnAndroidEnvironmentUnhandledException(object sender, RaiseThrowableEventArgs e)
{
// LOG
if (e.Exception is Java.IO.IOException) e.Handled = true;
}
}Also see #195, which is related. |

@paulcbetts I managed to get some line numbers on the call stack (no line numbers on system .dlls for some reason) for the issue @dbeattie71 was reporting involving task cancellation. I'm attaching the file I collected. Let me know if I can help in any other way. |

This is a stack trace from the Galaxy S5 Emulator (XAP). Similar exception. Reproducible every time I cancel a download. |
|
Running into this issue, but looks like this library is no longer in active development. |

Sometimes my android app using ModernHttpClient crashes.
I can't reproduce this problem, but it currently appears 1-2 times a day when using the app.
I'm on a Nexus 5 with Android 5.1.
Even if I try/catch the whole HttpClient.SendAsync with a general "Exception" handler, the app still completly crashes.
Do you have any idea?
This is the full stacktrace reported via hockeyapp:
