What is AsyncTask (deprecated) in Android SDK?

AsyncTask was a class in the Android SDK that allowed developers to perform background operations and publish results on the UI thread without having to manipulate threads and handlers. It was designed to be short-lived and was typically used for simple tasks such as downloading data or performing short computations.

However, AsyncTask has been deprecated since Android API level 30 (Android 11) due to its drawbacks, such as memory leaks and the potential for its lifecycle not aligning with that of the Activity or Fragment it is associated with.

Example of AsyncTask Usage

class DownloadTask extends AsyncTask { protected String doInBackground(String... urls) { // Code to download data return "Downloaded content"; } protected void onPostExecute(String result) { // Update UI with the result TextView textView = findViewById(R.id.textView); textView.setText(result); } }
