AsyncTask was commonly used in Android applications for performing background operations and updating the UI thread. Here’s a simple example of how it was used in production applications before it was deprecated.
// Example usage of AsyncTask in an Android app
private class DownloadFileTask extends AsyncTask {
protected String doInBackground(String... urls) {
String result = "";
// Simulate downloading a file
for (String url : urls) {
// Logic for downloading the file
// This could involve network operations
// Simulate progress
publishProgress(50);
}
return result;
}
protected void onProgressUpdate(Integer... progress) {
// Update UI with the progress
progressBar.setProgress(progress[0]);
}
protected void onPostExecute(String result) {
// Handle the result of the background processing
textView.setText(result);
}
}
