The core dispatcher logic in Android systems is typically implemented using components that manage threads and tasks, such as Looper, Handler, and MessageQueue. Looper creates a message processing loop in a thread, Handler allows sending and processing messages and Runnable objects, and MessageQueue stores these messages.

For example, the main thread (UI thread) has its own Looper and MessageQueue, which enables handling interface events and updating the UI. For background tasks, classes from the Jetpack library, such as WorkManager or Coroutines with Dispatchers, are often used to simplify asynchronous operation management.

An example of using Handler for task dispatching:

val handler = Handler(Looper.getMainLooper())
handler.post {
    // code to be executed on the main thread
}

Thus, the dispatcher logic is based on processing messages and tasks in a queue, ensuring sequential and safe execution of operations in the necessary threads.
