Question

I want to check progress of uploading file by HttpUrlConnection. How I can do this? I\'ve tried to calculate bytes when writing data in OutputStream

Right this code in your activity...

public class PublishPostToServer extends AsyncTask implements ProgressListenerForPost {

    public Context pContext;
    public long totalSize;
    private String response;

    public PublishPostToServer(Context context) {
        pContext = context;

    }

    protected void onPreExecute() {
        showProgressDialog();
    }

    @Override
    protected Boolean doInBackground(Void... params) {
        boolean success = true;
        try {
            response = NetworkAdaptor.getInstance()
                    .upLoadMultipartImageToServer(
                            "",
                            "",
                            "", this, this); // Add file path, Authkey, caption 

        } catch (Exception e) {
            success = false;
        }
        return success;
    }

    @Override
    protected void onPostExecute(Boolean result) {
        super.onPostExecute(result);
        //validateResponse(result, response);
    }

    @Override
    protected void onProgressUpdate(Integer... values) {

        try {
            if (mProgressDialog != null) {
                mProgressDialog.setProgress(values[0]);
            }
        } catch (Exception exception) {

        }
    }

    @Override
    public void transferred(long num) {
        publishProgress((int) ((num / (float) totalSize) * 100));
    }

}

private void showProgressDialog() {

    try {
        String dialogMsg = "Uploading Image...";
        mProgressDialog = new ProgressDialog(this);
        mProgressDialog.setMessage(dialogMsg);
        mProgressDialog.setIndeterminate(false);
        mProgressDialog.setMax(100);
        mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        mProgressDialog.setCancelable(false);
        mProgressDialog.show();
    } catch (Exception exception) {

    }
}

Now, Make a NetworkAdapter Class

public String upLoadMultipartImageToServer(String sourceFileUri, String auth_key, String caption, ProgressListenerForPost listiner, PublishPostToServer asyncListiner) { String upLoadServerUri = "" + "upload_image";

    HttpPost httppost = new HttpPost(upLoadServerUri);

    File file = new File(sourceFileUri);

    if (file.exists()) {

        FileBody filebodyVideo = new FileBody(file);
        CustomMultiPartEntity multipartEntity = new CustomMultiPartEntity(
                HttpMultipartMode.BROWSER_COMPATIBLE, listiner);
        try {
            multipartEntity.addPart("auth_key", new StringBody(auth_key));
            multipartEntity.addPart("caption", new StringBody(caption));
            multipartEntity.addPart("image", filebodyVideo);
            asyncListiner.totalSize = multipartEntity.getContentLength();
            httppost.setEntity(multipartEntity);

        }

        catch (UnsupportedEncodingException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }

        DefaultHttpClient mHttpClient = new DefaultHttpClient();
        String response = "";
        try {
            response = mHttpClient.execute(httppost,
                    new MovieUploadResponseHandler());
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return response;
    } else {
        return null;
    }

} 

@SuppressWarnings("rawtypes")
private class MovieUploadResponseHandler implements ResponseHandler {

    @Override
    public Object handleResponse(HttpResponse response)
            throws ClientProtocolException, IOException {

        HttpEntity r_entity = response.getEntity();
        String responseString = EntityUtils.toString(r_entity);
        // DebugHelper.printData("UPLOAD", responseString);

        return responseString;
    }

}

public static boolean isValidResponse(String resultData) {
    try {

    } catch (Exception exception) {
        //DebugHelper.printException(exception);
    }
    return true;
}

public String upLoadVideoToServer(String currentFilePath, String string,
        PublishPostToServer publishPostToServer,
        PublishPostToServer publishPostToServer2) {
    // TODO Auto-generated method stub
    return null;
}
