There may be a shortage of love on the internet for AsyncTasks, but that doesn’t mean they don’t have their uses. I’ve found myself using them a fair bit in the latest project that I’m working on. All in all, they make offloading tasks from the main thread quite simple, but can pose some challenges, particularly in tested environments.
The biggest challenge with using AsyncTask in tested code is that, since the code runs asynchronously, it can be difficult to ensure your tests get the right result for verification. I have seen some solutions for getting around this dilemma, but they involve pretty significant changes to the structure of your app, and exposing some internal members, simply for the sake of the tests.
