With these it helps You need to listen for asyntask complete listener, For that let your activity A impliment interface and call that method from Activity B,s Asyntask,s onpostexecute method Thus your activity A will come to know that B has finished his task and you can do next thing.. Hope this helps
code :
    public interface AsyncTaskCompletedListener {
        public void OnResultSucceeded(String result);

    public class LoginAsyncTask extends AsyncTask<String, Void, String> {
        AsyncTaskCompletedListener mAsyncTaskCompletedListener;

        protected String doInBackground(String... arg0) {
            // TODO Auto-generated method stub
            return null;

        protected void onPostExecute(String result) {
            // TODO Auto-generated method stub

From Activity A

LoginAsyncTask customloginasync = new LoginAsyncTask(getActivity(),
                FATCH_USER_LIST, arglist);


        customloginasync.setOnResultsListener(new AsyncTaskCompletedListener() {

            public void OnResultSucceeded(String result, int asyncTaskNo) {

                Logger.logInfo("CustomLogin data=========" + result);

fixed the issue. Will look into that further I've used AsyncTask quite a bit - but I have come across a seemingly simple question that confused me. The question is this:
code :
HttpResponse resp = makeHttpRequest();

Any of those help I know that AsyncTask are not preferred for long process. Their main objective is to take the load off from UI thread and do stuff in background. Later on completion update the respective UI thread. , First Question :
Yes you can.Its totally depends on your logic.
code :
    public void onDestroy(){
        //you may call the cancel() method but if it is not handled in doInBackground() method
        if (yourAsyncTask != null && yourAsyncTask.getStatus() != AsyncTask.Status.FINISHED)

wish help you to fix your issue Move the newSportEvent.saveInBackground() and related code to the onPostExecute() method in your AsyncTask. This will ensure this code will only get executed after the AsyncTask has completed.

hop of those help? Add callback to first AsyncTask and run second only after onPostExecute fired by first AsyncTask
Something like
code :
public interface AsyncFinishedCallback{
    public void onAsyncFinished();
public RestClient(Class<t> tClass, AsyncFinishedCallback callback)
    this.tClass = tClass; 
    this.callback = callback; //declare it somewhere as a field
protected void onPostExecute(String s) {
buttonConfirmar.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {

        restClient = new RestClient<>(MyObject.class, new AsyncFinishedCallback(){
    public void onAsyncFinished(){
            new WhenWebServiceConnectionFinished().execute();

hope this fix your issue I'm trying to build a demo app with 2 buttons, one downloads a video and the other downloads a PDF. I want to take care of the downloading in the background thread through AsyncTask. So far I have starter code with implemented methods. I haven't added the code for what I want to download yet because I want to figure out the logic behind separate downloads so for now, I have Log messages. , Don't do this
code :
DownloadingClass downloadingClass = new DownloadingClass();
new DownloadingClass().executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
