android, android-asynctask, download, eclipse

Solution

 private class DownloadFile extends AsyncTask<String, Integer, String> {
    ProgressDialog  mProgressDialog;
    String fileName=null;
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        // Create ProgressBar
         mProgressDialog = new ProgressDialog(Task.this);
        // Set your ProgressBar Title
        mProgressDialog.setTitle("Downloads");
        mProgressDialog.setIcon(R.drawable.dwnload);
        // Set your ProgressBar Message
        mProgressDialog.setMessage("Updating App Version, Please Wait!");
        mProgressDialog.setIndeterminate(false);
        mProgressDialog.setMax(100);
        mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        // Show ProgressBar
        mProgressDialog.setCancelable(false);
      //  mProgressDialog.setCanceledOnTouchOutside(false);
        mProgressDialog.show();
    }

    @Override
    protected String doInBackground(String... sUrl) {
        try {
                    String apkurl = "http://google.com/"+fileName;
                    URL url = new URL(apkurl);
                    HttpURLConnection c = (HttpURLConnection) url
                            .openConnection();
                    c.setRequestMethod("GET");
                    c.setDoOutput(true);
                    c.connect();
                    int fileLength = c.getContentLength();    

                    //File file = new File(PATH);
                    if(file.exists())
                    {
                        file.delete();
                    }
                    file.mkdirs();
                    File outputFile = new File(file, fileName);
        final FileOutputStream fos = new FileOutputStream(outputFile);

                    final InputStream is = c.getInputStream();


            byte data[] = new byte[1024];
            long total = 0;
            int count;
            while ((count = is.read(data)) != -1) {
                total += count;
                // Publish the progress
                publishProgress((int) (total * 100 / fileLength));
                fos.write(data, 0, count);
            }

            // Close connection
            fos.flush();
            fos.close();
            is.close();
            }
    }

    catch (Exception e) {
            // Error Log
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return null;
 }

    @Override
    protected void onPostExecute(String result) {
        // TODO Auto-generated method stub
        mProgressDialog.dismiss();
    }

    @Override
    protected void onProgressUpdate(Integer... progress) {
        super.onProgressUpdate(progress);
        // Update the ProgressBar
        mProgressDialog.setProgress(progress[0]);
    }
}

Problem

I can't build my project because eclipse giving error Here is button click event who starting download ``` button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { ProgressDialog mProgressDialog; mProgressDialog = new ProgressDialog(Test.this); mProgressDialog.setMessage("Pobieranie"); mProgressDialog.setIndeterminate(false); mProgressDialog.setMax(100); mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); DownloadFile downloadFile = new DownloadFile(); downloadFile.execute("http://google.com"); } }); ``` and AsyncTask function ``` private class DownloadFile extends AsyncTask<String, Integer, String> { [...] @Override protected void onPreExecute() { super.onPreExecute(); mProgressDialog.show(); // Here eclipse tell that "mProgressDialog cannot be resolved" } @Override protected void onProgressUpdate(Integer... progress) { super.onProgressUpdate(progress); mProgressDialog.setProgress(progress[0]); // Here eclipse tell that "mProgressDialog cannot be resolved" } } ``` So where I should insert code who create my progress dialog?
