问题描述

我想检测我的Android应用中何时发生未捕获的异常

I want to detect when an uncaught exception has happened in my Android app.

一旦检测到,我想显示一个确认对话框

Once detected, I want to display a confirmation dialog

如何显示此确认对话框?当我尝试了各种技术时,UI无响应并且似乎被冻结。

How do I get this confirmation dialog to display? When I tried various techniques, the UI is unresponsive and appears to be frozen.

我的代码对此做出了响应:

My code responds to this:

new CatchAllExceptionHandler(this) is my custom handler
Thread.setDefaultUncaughtExceptionHandler(new CatchAllExceptionHandler(this));

我已经尝试了 CatchAllExceptionHandler 的这两种实现:

I have tried these two implementations of CatchAllExceptionHandler:


  1. 显示警报对话框

  2. 启动活动,然后在onCreate <之后显示警报对话框

这两种方法均失败。

所以我的问题是:如何使确认对话框正确显示?

So my question is: How to I get the confirmation dialog to properly display?

推荐答案

您可能正在尝试在非UI线程上执行UI操作。使用任何可用的技术( Handler Handler#post View#post Activity#runOnUiThread AsyncTask#onPostExecute )来安排您的UI工作UI线程。

You may be attempting to do your UI operations on a non-UI thread. Use any of the available techniques (Handler, Handler#post, View#post, Activity#runOnUiThread, AsyncTask#onPostExecute) to arrange for your UI work to be done on the UI thread.
