The idea here is that I'm using the code to view the Android source code, so it doesn't match the original design idea of Google engineer 100% (or maybe 0%), but this article will certainly help you understand asynctask, or something you haven't found before. As we all know, Android's main thread (also known as UI thread, thread ID 1) has some restrictions, so that the main thread can not do some things, such as access to the network is not allowed,

HandlerthreadIn the last Android time-consuming task _handler introduced the handler mechanism, and introduced a simple example of a common thread that generates Looper and communicates using handler mechanisms. We know that there is no looper in the normal thread, and it is not good to use the handler mechanism in normal thread space, and it would be a little cumbersome to do it each time as in the previou

Asynctask is a lightweight asynchronous class provided by Android that can directly inherit Asynctask, implement asynchronous operations in a class, and provide the degree to which interface feedback is currently performed asynchronously (UI progress updates can be implemented via interfaces), and the final feedback is performed to the UI main thread.
