After a relatively easy coast to simple app coding, I would like to understand better the intricate relationships between various conceptual components in Android.
More specifically, I would like to understand what is Runnable, Looper and Handler.
As you may noticed, the above 3 terms are links to formal documentation in http://developer.android.com so my question may seem strange, so let me explain: That documentation may be perfect for someone who already understands how things work in Android, but I need something that sequentially walks through fundamentals, building on top of previous concepts.
To summarize, I need some sort of tutorial on core inner building blocks of Android. Can you recommend one?
The detailed article Painless Threading is probably your best resource for threading on Android.
The moral of the story is that AsyncTask makes multithreading easier for you.
