Java.util.zip.GZIPInputStream.readFully when loading a file in android

Question

I gave internet permission and when I tried to download the doc file from url I got java.io.EOFException In my case, when I hit the URL in the browser, it downloaded successfully on the PC, but it doesn’t work on my device.

class DownloadFileFromURL extends AsyncTask<String, String, String> {

        /**
         * Before starting background thread
         * Show Progress Bar Dialog
         */

        @SuppressWarnings("deprecation")
        @Override
        protected void onPreExecute() {
            super.onPreExecute();

            try {
                pDialog = new ProgressDialog(getApplicationContext());
                pDialog.setMessage("Downloading file. Please wait...");
                pDialog.setCancelable(false);
                pDialog.show();

            } catch (Exception anfe) {

            }
        }
