Android Question How does callsub work with threads?

How are you creating the new thread? What is it used for?

CallSub (unlike CallSubDelayed) will be executed on the thread that called it.

I'm using a threading library from agraham.

Actually what is going on is thee ICos weather library goes out and gets weather information when you set the city property. That can sometimes cause a delay, depending on your connection. This code is then reading the weather object and populating a global object with the current weather data.

I then wanted to notify all listeners (UI classes) that new weather information has appeared and let them update.

I just noticed the thread object has a Done event that I can use.
