Android ProgressBar not updating onProgress

Question

The progress bar is not updating. However, this ends when the task is completed.

int totalSms = 12; int currentSms = 0; public class ProgressTask extends AsyncTask<String, Integer, Boolean> { /** progress dialog to show user that the backup is processing. */ private ProgressDialog dialog; public ProgressTask(ScanInboxActivity activity) { dialog = new ProgressDialog(activity); dialog.setIndeterminate(true); dialog.setCancelable(false); dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); dialog.setMax(totalSms); } protected void onPreExecute() { dialog.setMessage("Scan start"); dialog.show(); } @Override protected void onProgressUpdate(Integer... values) { Log.d(TAG, "in onProgressUpdate: " + values[0]); // shows actuall count in the log dialog.setProgress(values[0]); // does not update //tried even this, does not work //dialog.incrementProgressBy(values[0]); } @Override protected void onPostExecute(final Boolean success) { if (dialog.isShowing()) { dialog.dismiss(); } populateList(); } protected Boolean doInBackground(final String... args) { try { Context context = getApplicationContext(); SharedPreferences prefs = PreferenceManager .getDefaultSharedPreferences(context); while (currentSms < totalSms) { Thread.sleep(1000); currentSms++; publishProgress(currentSms); } } catch (IllegalArgumentException e) { } catch (InterruptedException e) { } return true; } 

Answer 1

 dialog.setIndeterminate(true); 

it must be false , otherwise the load value will not be evaluated
