Kuidas saab korraldada andmete edastamist taustprotsessist peamise täitmise niidile?

In Android, to transfer data from a background thread to the main (UI) thread, several approaches are commonly used:

• Handler: created in the main thread and receives messages or Runnables from the background thread.
• runOnUiThread: method of Activity that allows executing code in the UI thread.
• LiveData: observable entity, whose updates are automatically delivered to the UI.
• ViewModel + Coroutine with Dispatchers.Main: coroutines enable switching between threads.

Example with Handler:

Handler mainHandler = new Handler(Looper.getMainLooper());

new Thread(() -> {
    // Background work
    String result = "Data from background thread";

    mainHandler.post(() -> {
        // UI update
        textView.setText(result);
    });
}).start();
