Fun fact : Modern CPUs can only handle a certain number of threads at one time. Once you get above that limit, they have to start scheduling which thread gets the next open block of CPU processing time. And even better : This can influence the performance of your Android app.

In this video +Colt McAnlis introduces the concept of thread priority, why it’s important to work with, and how to set it for threads you create, in a very sane way.

Let’s say you’ve got some 20 bitmaps being decoded on a worker thread. Well, what happens if your activity is destroyed before that work completes?

In this video Doug Stevenson explains Loaders. A super-helpful class that can give you insight into how the activity lifecycle is changing, so that you can better understand how to address threaded work that might be in flight.

Swimming in Threadpools

We know that you’re an awesome engineer, and you’re using threading to the MAX. But over time, it gets harder and harder to handle how work is distributed across all those AsyncTasks and HandlerThreads. It gets especially tricky when you try to break up large blocks of work, like image processing, and find a threaded solution for it.

While AsyncTask is the most useful threading class you can use, there’s some situations where it just doesn’t make sense. For example, AsyncTasks aren’t good for long-running work, or for threaded callbacks. Learn more in this video with +Colt McAnlis. #Perfmatters

AsyncTask is awesome, but far from a silver bullet; there’s a few nuances and tricks that come alongside this handy helper, which if you don’t pay attention to, can lead to memory leaks, headaches, and other sorts of craziness.
