不可用的组件HockeyApp for Android(Xamarin组件商店)

标签: c# android xamarin xamarin.android hockeyapp

我试图将上面提到的组件投入使用。

http://components.xamarin.com/view/hockeyappios

我创建了一个基于Xamarin Studio模板的非常简单的项目(Android Ice Cream Sandwich Application) 然后我添加了向HockeyApp发送异常的必要代码。此代码在下一页

中介绍

http://components.xamarin.com/gettingstarted/hockeyappandroid

不幸的是,我发现了存储例外信息文件的主要问题

HockeyApp.ManagedExceptionHandler.SaveException (e.ExceptionObject)

此调用会导致以下错误

在检查问题时,我发现了以下信息

  • 处理异常可以毫无问题地存储
  • 仅在AppDomain.CurrentDomain.UnhandledException处理程序
  • 中出现问题

然后我在AppDomain.CurrentDomain.UnhandledException处理程序

中尝试了以下代码
string eStr = e.ExceptionObject.ToString();
Java.Lang.Throwable thr = new Java.Lang.Throwable(eStr);

此代码导致非常相似的错误

这是代码调用的一般问题,在AppDomain.CurrentDomain.UnhandledException中使用“java binding”吗?

2 个答案:

答案 0 :(得分:4)

第二个错误是因为未处理的c#异常的异常处理程序在一个真正没有JNI访问权限的有趣空间中运行。

通过直接写出HockeyApp格式的C#异常并且只将Java异常直接报告给HockeyApp库,你可以使它在没有带有一点包装胶的组件的情况下工作。

这就是我使用的https://github.com/tpurtell/AndroidHockeyApp/blob/master/Additions/TraceWriter.cs#L84

HockeyApp对于Exception的格式化有点迂腐,所以这段代码不是很完美,会导致一些堆栈跟踪在他们的网站上通过异常名称组合在一起,但例外情况都会在这里进行。< / p>

答案 1 :(得分:0)

这是一个更容易解决问题的方法

使用:

  AndroidEnvironment.UnhandledExceptionRaiser += (s, e) => 
       HockeyApp.ManagedExceptionHandler.SaveException(e.Exception);
  Thread.DefaultUncaughtExceptionHandler = new UnCaughtExceptionHandler(this);

intead of:

AppDomain.CurrentDomain.UnhandledException += (sender, e) => 
            HockeyApp.ManagedExceptionHandler.SaveException (e.ExceptionObject);

其中UnCaughtExceptionHandler只是您对该类的实现,而后者又使用HockeyApp.ManagedExceptionHandler.SaveException()来记录异常(完整实现位于之下)。这是HockeyApp.ManagedExceptionHandler.SaveException(object exceptionObject)引发的异常的一种解决方法,我想这最终会被整理出来。


UnCaughtExceptionHandler类实现

    class UnCaughtExceptionHandler : Java.Lang.Object, Thread.IUncaughtExceptionHandler
    {
        readonly Context context;
        public UnCaughtExceptionHandler(Context context)
        {
            this.context = context;
        }

        public void UncaughtException(Thread thread, Throwable ex)
        {
           HockeyApp.ManagedExceptionHandler.SaveException(ex);
        }

    }
