Async Task are UI Threads, probably that's the reason.. try creating
Threads from any bound Services to perform the download and retreive the
download status from service and update that in the UI whenever required..

[android-developers] Problem in Asynctask Execution in standby mode

[sktniran]

Hi friends,

I am using AsyncTask concept to download data from
server.

 private class DownloadTask extends AsyncTask
 {
private ProgressDialog progressDialog;

 @Override
 protected void onPreExecute()
 {
super.onPreExecute();
progressDialog = new ProgressDialog(ActivityTab.this);
progressDialog.setProgress(10);
progressDialog.setSecondaryProgress(32);

progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressDialog.setMessage("Downloading...");
progressDialog.show();
 }

 protected String doInBackground(Void... params)
 {
 String result=" ";
 result = download();
 return result;
 }

 protected void onPostExecute(String result)
 {
 if(progressDialog.isShowing())
progressDialog.dismiss();
Toast.makeText(getApplicationContext(),"
"+result.toString(),Toast.LENGTH_LONG).show();
 }
 }


in download button click i called
  new DownloadTask().execute();


This is working well. the thing is if device goes to standby mode
(Screen goes off) while showing this downloading.. progressbar mean my
application getting force closed. it says like IllegalStateException.
how to solve this probelm? it is there any way to prevent screen from
locking untill complete this download process?  please help me.
