理想的方式来设置Android的全球未捕获的异常处理程序 [英] Ideal way to set global uncaught exception Handler in Android

问题描述

我想成立一​​个全球性的未捕获的异常处理程序在我的Andr​​oid应用程序中的所有线程。所以，在我的应用程序子我订的 Thread.UncaughtExceptionHandler 作为默认处理未捕获异常的实现。

I want to set a global uncaught exception handler for all the threads in my Android application. So, in my Application subclass I set an implementation of Thread.UncaughtExceptionHandler as default handler for uncaught exceptions.

Thread.setDefaultUncaughtExceptionHandler(
                new DefaultExceptionHandler(this));

在我的实现，我想显示 AlertDialog 显示相应的异常信息。

In my implementation, I am trying to display an AlertDialog displaying appropriate exception message.

不过，这似乎并没有工作。无论何时，一个异常被抛出肚里任何线程未经处理的，我得到的股票，操作系统默认对话框（对不起！ - 应用 - 已-停意外对话框）。

However, this doesn't seem to work. Whenever, an exception is thrown for any thread which goes un-handled, I get the stock, OS-default dialog ("Sorry!-Application-has-stopped-unexpectedly dialog").

什么是正确的和理想的方法来设置一个默认的处理程序捕获的异常？

What is the correct and ideal way to set a default handler for uncaught exceptions?

推荐答案

这应该是所有你需要做的。 （请确保您导致进程暂停之后 - 事情可能是在一个不确定的状态）

That should be all you need to do. (Make sure you cause the process to halt afterward -- things could be in an uncertain state.)

要检查的第一件事是，是否在Android的处理器是获取调用。这可能是你的版本被调用，但没有致命的system_server呈现出通用对话框时，看到的进程崩溃。

The first thing to check is whether the Android handler is still getting called. It's possible that your version is being called but failing fatally and the system_server is showing a generic dialog when it sees the process crash.

添加一些日志信息的处理程序的顶部，看它是否到达那里。打印从getDefaultUncaughtExceptionHandler的结果，然后抛出一个未捕获的异常会导致崩溃。保持眼睛上的logcat输出，看看发生了什么事情。

Add some log messages at the top of your handler to see if it's getting there. Print the result from getDefaultUncaughtExceptionHandler and then throw an uncaught exception to cause a crash. Keep an eye on the logcat output to see what's going on.
