MULTI-THREADING, CONCURRENCY AND ASYNC ON ANDROID
summary
Covers concrete internals (zygote uses clone, Linux treats threads and processes as tasks) and practical gotchas: Thread.interrupt only sets a flag so long reads must check interruption, callbacks must be delivered on the main thread, and the surprising top crash is NullPointerException, not IllegalStateException. Walks through Android tools and behaviors: Handler/Looper/MessageQueue, HandlerThread, AsyncTask (posts results via Handler), IntentService, Loaders, RxJava and support annotations, with practical cancellation and lifecycle notes.
