Hello, I'm trying to have my IntentService show a Toast message,
but when sending it from the onHandleIntent message, the toast shows but gets stuck and the screen and never leaved.
I'm guessing its because the onHandleIntent method does not happen on the main service thread, but how can I move it?
Has anyone has this issue and solved i...
I'm confused about how asyncnotifier works. What exactly is threaded in the notifier? Is the just the watcher threaded? Or does each of the callbacks to the handler functions run on its own thread?
The documentation says essentially nothing about the specifics of the class.

I have a producer-consumer scenario in ASP.NET. I designed a Producer class, a Consumer class and a class for holding the shared objects and responsible for communication between Producer and Consumer, lets call it Mediator. Because I fork the execution path at start-up (in parent object) and one thread would call Producer.Start() and an...
Inline Java IDE hint states, "Invoking Thread.sleep in loop can cause performance problems." I can find no elucidation elsewhere in the docs re. this statement.
Why? How? What other method might there be to delay execution of a thread?

I have been learning thread programming in Java, where there are are sophisticated APIs for thread management. I recently came across this. I am curious to know if these are used now. Is the POSIX thread obsolete or is it the standard used now for threading in C++. I am not familiar with Threading in any other language apart from Java.

I have multiple threads, and I want each thread to wait for every others to complete at certain point in the code before proceeding as following:

In my application I'm performing somewhat heavy lookup operations. These operations must be done within a single thread (persistence framework limitation).
I want to cache the results. Thus, I have a class UMRCache, with an inner class Worker:

Hi,
I am just a starter at using threads in my code. I use Boost threads usually.
But I don't think I have mastered this field yet.
I am looking for learning material specifically for advanced parallel programming. Could anybody suggest something.
