AsyncTask has been deprecated in Android 11.
There are a lot of alternatives to AsyncTask like RxJava, Services, Coroutines, etc.
CoroutineTask is a utility that has the same structure as AsyncTask but uses Kotlin Coroutines underneath
In the same way you use AsyncTask, just replace the keyword AsyncTask with CoroutineTask
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.9'CoroutineTask.kt val asyncTask = object: CoroutineTask <String?, Int?, String?>() { override fun onPreExecute() {} override fun doInBackground(vararg params: String?): String? { for (i in 0. .100000) { // optional, publishing the progress val progress: Int = (i / 1000) publishProgress(progress) } return params[0] } override fun onPostExecute(result: String?) { Toast.makeText(applicationContext, result, LENGTH_LONG).show() } override fun onCancelled() {} override fun onProgressUpdate(progress: Int?) { Log.i("progress: ", "" + progress) } } asyncTask.execute("background work completed")val asyncTask: CoroutineTask <Void?, Void?, String?> = object : CoroutineTask <Void?, Void?, String?>() { override fun onPreExecute() { // do something } override fun doInBackground(vararg params: Void?): String? { return "" } override fun onPostExecute(result: String?) { // do something } override fun onCancelled() { // optional } } asyncTask.execute()CoroutineTask asyncTask = new CoroutineTask <Void, Void, String>() { @Override protected void onPreExecute() {} @Override protected String doInBackground(Void... params) { return ""; } @Override protected void onPostExecute(String result) {} @Override protected void onCancelled() { // optional } }; asyncTask.execute();CoroutineTask asyncTask = new CoroutineTask <Void, Void, String>() { @Override protected void onPreExecute() {} @Override protected String doInBackground(Void... params) { return ""; } @Override protected void onPostExecute(String result) {} }; asyncTask.execute();asyncTask.cancel(true);
