Send Image to Server

Question

When I send a byte[] converted to String to the server on the server comes empty or breaks. I don’t understand why.

  Bitmap photo = (Bitmap)data.getExtras().get("data");
                    photo = Bitmap.createScaledBitmap(photo, 800, 1422, false);
                    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
                    photo.compress(Bitmap.CompressFormat.PNG, 100, bytes);

                    byte[] imageArray = bytes.toByteArray();

                    String imageAsString = Base64.encodeToString(imageArray, Base64.DEFAULT);

Then to send to the server do:

private String InsertImage(String url)
{
    HttpClient client = buildHttpClient();
    HttpPost request = new HttpPost(url);
    HttpResponse response = null;
    String responseString = "";

    try
    {
        System.out.println("VOU PARA O SERVIDOR");
        JSONObject jsonObject = this.setHeadersAndbuildJSONObject(request);

        System.out.println("vou levar 1 - " + sessionID);
        System.out.println("vou levar 2 - " + data[0]);
        System.out.println("vou levar 3 - " + data[1]);

        jsonObject.put("SessionGUID", sessionID);
        jsonObject.put("Address", data[0]);
        jsonObject.put("imageAsBytes", data[1]);

        responseString = this.executeRequest(jsonObject, request, response, client);
        System.out.println("VIM DO SERVIDOR " + responseString.toString());

    }
    catch (Exception e)
    {
        System.out.println("ERRO " + e.getMessage());
    }
    return responseString;
}

In the system.out you see the variables are all well filled. On the server side burst comes with the following error "Object Reference not set to an instance of an Object."

Hello! You are sending the byte image[] to the server for some special reason ?

Why don’t you use an http lib to send the file over HTTP POST ? It will be much simpler, and you don’t need to invent the wheel, serialize and deserialize, etc.

In the link below you have an example ready exactly what you need:
