I use Http multipart for performing image and video upload. Sadly these are not part of the android sdk, so we have to import the multipart lib as part of your project.

Here is an awesome answer that helped me.

Dont forget to cross check that the key-value pair that you are adding as multipart is exactly what the server is expecting.

Try this code..

   private void uploadPhoto(Bitmap photo)
    {
    MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

    try 
    {

        ContentBody contentPart = null;
        if(photo != null)
        {
            String filename="temp.jpg";
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            photo.compress(Bitmap.CompressFormat.JPEG, 100, bos);
            contentPart = new ByteArrayBody(bos.toByteArray(), filename);        

            String root = "sdcard path";
            File myDir = new File(root );    
            myDir.mkdirs();
            String fname = filename;
            File file = new File (myDir, fname);
            if (file.exists ()) file.delete (); 
            try {
                FileOutputStream out = new FileOutputStream(file);
                photo.compress(Bitmap.CompressFormat.JPEG, 90, out);
                out.flush();
                out.close();

            } catch (Exception e) {
                e.printStackTrace();
            }

            reqEntity.addPart("image", contentPart);
        }



        String url = "your url";
        String response = multipost(url, reqEntity);

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
}

and here is code for multipost

   public String multipost(String urlString, MultipartEntity reqEntity) {


HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(urlString);
//
try {

    httppost.setEntity(reqEntity);
    HttpResponse response = httpclient.execute(httppost);
    InputStream is = response.getEntity().getContent();

}
catch(Exception e)
{
    Log.e("tag", "Error:  "+e.toString());
}

return null;        
}

then call uploadphoto method...when u want.... Hope this will help u...:)
