    android android-asynctask lifecycle
    I have an activity in which I collect data for an online transaction. When the collection is done, I run a background thread (more specifically an AsyncTask) that calls a web-service and waits for its response, then return it to the activity. Meanwhile, a progress dialog shows up.I want the background process to be cancelled if the application finishes or user cancels (however, I still need to notify the web-service), and retained if the activity is destroyed due to a configuration change or to

    asp.net lifecycle httpapplication
    I want to know which parts of the ASP.NET request life cycle happen after an error is handled via the HttpApplication.Error event. Specifically, which of the events listed at http://msdn.microsoft.com/en-us/library/bb470252.aspx#Stages fire after an error? I know that EndRequest still fires, and I suspect that PreSendRequestHeaders and PreSendRequestContent fire as well, but aside from these I have no idea.Does it depend on when in the life cycle the error occurs? Does it depend on whether I cal

    java multithreading lifecycle main-method
    When does a typical Java app finish?If I start a new thread in the main method and then the main method finishes, but the other thread continues working, the app would still be on until all it’s threads have died, wouldn’t it?Thanks & Merry Christmas!

    flex components spark lifecycle
    I have recently migrated some of my projects to the shiny new Flex 4.6 SDK. I wasn’t expecting much trouble since it was only a minor release. But as a matter of fact I got hundreds of errors all over the place. These errors would mostly come from Spark SkinnableComponents; for example:override protected function getCurrentSkinState():String {return mySkinPart.someProperty ? “normal” : “someOtherState”; }would work just fine under 4.5, but would throw me a nullpointer error in 4.6. The reason is
