How to use HandlerThread in an Android app?

HandlerThread is a useful class in Android that allows you to create a background thread with a looper. This thread can handle asynchronous operations without blocking the main UI thread, making it ideal for tasks that require continuous processing.

How to use HandlerThread in an Android app

To use HandlerThread, follow these steps:

  1. Create an instance of HandlerThread.
  2. Start the handler thread.
  3. Create a new Handler associated with the thread's looper.
  4. Use the Handler to post tasks to be executed on the background thread.
  5. Quit the HandlerThread when done.

Example Code:

// Creating a HandlerThread HandlerThread handlerThread = new HandlerThread("MyHandlerThread"); handlerThread.start(); // Creating a Handler associated with the HandlerThread's looper Handler handler = new Handler(handlerThread.getLooper()); // Posting a task to the Handler handler.post(new Runnable() { @Override public void run() { // Your background code here Log.d("HandlerThread", "Running on background thread"); } }); // Don't forget to quit the HandlerThread when done handlerThread.quitSafely();
