Question

I need help here, my DIALOG_DOWNLOAD_PROGRESS always shows 100% on onPreExecute() (Second Download Attempt). How to make it start from 0% from the second attempt download. Need help here. Thanks

@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DIALOG_DOWNLOAD_PROGRESS:
        mProgressDialog = new ProgressDialog(this);
        mProgressDialog.setMessage("Downloading file..");
        mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        mProgressDialog.setCancelable(true);
        mProgressDialog.show();
        return mProgressDialog;
    default:

        return null;
    }
}

class DownloadFileAsync extends AsyncTask {

@Override
protected void onPreExecute() {
    super.onPreExecute();
    showDialog(DIALOG_DOWNLOAD_PROGRESS);
}

….

}
protected void onProgressUpdate(String... progress) {
     Log.d("ANDRO_ASYNC",progress[0]);
     mProgressDialog.setProgress(Integer.parseInt(progress[0]));

}

@Override
protected void onPostExecute(String unused) {
    dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
}

since onCreateDialog is called only once to create the dialog, you’ll have to reset the dialog in onPrepareDialog which is called every time before the dialog is shown.

@Override
protected void onPrepareDialog(int id, Dialog dialog, Bundle args) 
    if (id == DIALOG_DOWNLOAD_PROGRESS)
        mProgressDialog.setProgress(0);
}
