HttpPost image in Android

Question

I am trying to do an HTTP Post to a URL.

I followed the code from this answer:

http://stackoverflow.com/questions/2935946/sending-images-using-http-post

All HttpComponent libraries has been successfully included to my project.

However i am getting this error when testing the code on the phone:

This is my Code:

public class HttpContentPost {
    private static final String BASE_URL = "http://example.com/api/index.php";
    public static void sendPost(String imagePath, ProductRaw data)

        String responseBody;
        HttpClient client = new DefaultHttpClient();
        HttpPost request = new HttpPost(BASE_URL);

        MultipartEntity entity = new MultipartEntity(
                HttpMultipartMode.BROWSER_COMPATIBLE);

        File file = new File(imagePath);
        ContentBody encFile = new FileBody(file,"image/jpg");

        Log.i("TAG", "BUILDING HTTP ENTITY");
        entity.addPart("file", encFile);
        entity.addPart("action", new StringBody("publishMarket"));
        entity.addPart("email", new StringBody(data.ownerEmail));
        entity.addPart("password", new StringBody(data.ownerPasswd));
        entity.addPart("title", new StringBody(data.productName));
        entity.addPart("description", new StringBody(data.productDesc));
        entity.addPart("currency_code", new StringBody(data.productCurrency));
        entity.addPart("price", new StringBody(data.productPrice));
        entity.addPart("category", new StringBody(data.productCat));
        entity.addPart("tag", new StringBody(data.productTag));

        request.setEntity(entity);
        Log.i("TAG", request.toString());

        ResponseHandler<String> responsehandler = new BasicResponseHandler();
        responseBody = client.execute(request, responsehandler);

        if (responseBody != null && responseBody.length() > 0) {
            Log.w("TAG", "Response image upload" + responseBody);

        }
    }
}

Does anyone know how can i solve this?

Pplease check following code :

Answer 2

I ended up doing the following:

1. Remove the required libraries (Project properties > Library tabs > remove said *jars
2. Remove the required *jars from my libs directory of my Project
3. Clean my project

4. Restart Eclipse

5. re-add required *jars (Project properties > Library tabs > Add External JARs

6. (weirdly enough) Change the order of the said JARs from the Order and Export tabs (i put the jars order immediately after the src + gen folders of my Projects.
7. once again do a Clean
8. Run the apps..

I however cannot explain why these steps. I just read through all (and tried all) the solution provided in this question here NoClassDefFoundError - Eclipse and Android

Hope this could help you in the future.
