阅读更多关于 Android UncaughtExceptionHandler that instantiates an AlertDialog breaks

As the title says, I have an UncaughtExceptionHandler set in my custom application class that gets set as the default when my application starts. However, while not in the documentation I have read that you cannot instantiate a Dialog using MyApplication.this or getApplicationContext() . When I try to do it, I get a WindowManager$BadTokenException... I need an alternative. I have thought of making a new activity to compensate for this but would rather have it be an AlertDialog . Is there a way I can get a valid context to my UncaughtExceptionHandler from inside MyApplication class? I have read

OK, so I have a problem. If an uncaught exception occurs while I am handling an HTTP request, I have no opportunity to call the end() method on the http.ServerResponse object. Therefore, the server hangs forever and never fulfills the request. Here's an example: var express = require('express'); var app = express.createServer(); var reqNum = 0; app.get('/favicon.ico', function(req, res) {res.send(404);}); app.get('*', function(req, res, next) { console.log("Request #", ++reqNum, ":", req.url); next(); }); app.get('/error', function(req, res, next) { throw new Error("Problem occurred"); }); app
