Question

在asp.net中，我可以使用以下代码来处理未捕获的错误。

但Android应用程序，我不知道如何编写代码以避免整个应用程序崩溃。

void Application_Error(object sender, EventArgs e) 
{
    string lr = "\n\n";
    string lan = "";

    try
    {
        if (Request.UserLanguages.Length >= 1)
        {
            for (int i = 0; i <= Request.UserLanguages.Length - 1; i++)
            {
                lan = lan + " " + Request.UserLanguages[i];
            }
        }
    }
    catch
    {
    }

    Exception ex = Server.GetLastError().GetBaseException();
    string errorMessage = ex.Message;
    string title = "E: " + ex.Message;

    string LoginedUser = "";
    if (HttpContext.Current.Request.IsAuthenticated)
    {
        LoginedUser = HttpContext.Current.User.Identity.Name;
    }
    else
    {
        LoginedUser = "Anonymous";
    }


    string content = "Error Message: " + ex.Message
                   + lr
                   + "Request URL: " + Request.Url.ToString()
                   + lr
                   + "Request IP: " + Request.UserHostAddress + "    Language: " + lan + "    Logined User: " + LoginedUser
                   + lr;

    content = content + "Beijing Time: " + DateTime.UtcNow.AddHours(8).ToString() + " ( UTC+8 )     Web Server Local Time: " + DateTime.Now.ToString() + lr;


    //-----------------------------------
    StringBuilder message = new StringBuilder();
    if (Server != null)
    {
        Exception ee;
        const string exceptionFormat = "{0}: \"{1}\"\r\n{2}\r\n\r\n";
        for (ee = Server.GetLastError(); ee != null; ee = ee.InnerException)
        {
            message.AppendFormat(exceptionFormat,
            ee.GetType().Name,
            ee.Message,
            ee.StackTrace);
        }
    }
    content = content + message.ToString();
    //------------------------------------

    if (!Request.IsLocal)
    {
        if (IsCanSend(errorMessage))
        {
            string fromEmail = ConfigurationManager.AppSettings["FromEmail"];
            string toEmail = ConfigurationManager.AppSettings["ToErrorEmail"];
            CuiWei.Utility.ATMSendEmail.SendEmail(fromEmail, toEmail, title, content, false, "", new System.Net.Mail.SmtpClient());
        }
    }

    Server.Transfer("~/Error.aspx?ErrorInfo=" + ex.Message);
    Server.ClearError();        
}

Answer 1

我在onCreate（）中使用此代码：

    final UncaughtExceptionHandler defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
    Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler() {
        @Override
        public void uncaughtException(Thread thread, Throwable ex) {        
            //TODO Handle Exception
            defaultUEH.uncaughtException(thread, ex);
        }
    });

因此您可以记录错误。如果删除该行 "defaultUEH.uncaughtException(thread, ex);" 它应该继续运行但应用程序可能处于未定义状态，所以要小心。

Answer 2

您需要设置UncaughtExceptionHandler

您可以根据需要实施此操作。但我建议你看一下ACRA。它具有更多功能，而且非常易于使用。

Android有全局错误句柄功能吗？
