How Handler and Looper actually work together #androiddevelopment #aosp

What really happens inside the Android main thread?

In this short video, I explain how Handler, Looper, MessageQueue, and Thread work together under the hood.

A Handler does not execute code by itself.
MessageQueue stores messages and tasks.
Looper continuously takes messages from the queue.
And the actual code is executed by the Thread.

This mechanism is one of the most important parts of Android internals. It explains how UI events, lifecycle callbacks, clicks, rendering, and framework messages are processed inside an Android application.

If you want to understand Android beyond Activities, Fragments, and Compose, this is a key concept to learn.
