In order to give users a good interactive experience, in the development of Android applications need to put heavy tasks (IO, network connectivity, etc.) into other threads asynchronous execution, to achieve the effect of not blocking the UI.
This series of articles introduces the implementation method of asynchronous processing and the realization principle of the system at the bottom.
Android asynchronous processing one: using Thread+handler to implement non-UI thread update UI interface (Getting started)
Describes how to use Thread+handler to send an interface update message from a non-UI thread to the UI thread
Android asynchronous processing two: using Asynctask to update the UI interface asynchronously (Getting started)
Describes how to use Asynctask to update the UI interface asynchronously
Android asynchronous processing three: Handler+looper+messagequeue in-depth (advanced)
Tracking system code, introducing the implementation principle of Thread+handler
Android asynchronous processing Four: the implementation principle of Asynctask (Advanced)
Tracking system code, introducing the realization principle of system bottom asynctask
