Wrap it all up in an Async task to avoid threading errors   public class AsyncHttpPostTask extends AsyncTask lt File  Void  String gt         private static final String TAG   AsyncHttpPostTask class getSimpleName        private String server       public AsyncHttpPostTask final String server            this server   server              Override     protected String doInBackground File    params            Log d TAG   doInBackground            HttpClient http   AndroidHttpClient newInstance  MyApp            HttpPost method   new HttpPost this server           method setEntity new FileEntity params 0    text plain             try               HttpResponse response   http execute method               BufferedReader rd   new BufferedReader new InputStreamReader                      response getEntity   getContent                  final StringBuilder out   new StringBuilder                String line              try                   while   line   rd readLine       null                        out append line                                   catch  Exception e                    wr close                try                   rd close                  catch  IOException e                    e printStackTrace                                 final String serverResponse   slurp is               Log d TAG   serverResponse      out toString               catch  ClientProtocolException e                e printStackTrace              catch  IOException e                e printStackTrace                      return null

the most effective method is to use org apache http entity mime MultipartEntity   see this code from the link using  org apache http entity mime MultipartEntity   public class SimplePostRequestTest3                param args         public static void main String   args        HttpClient httpclient   new DefaultHttpClient        HttpPost httppost   new HttpPost  http   localhost 8080 HTTP TEST APP index jsp         try         FileBody bin   new FileBody new File  C  ABC txt           StringBody comment   new StringBody  BETHECODER HttpClient Tutorials           MultipartEntity reqEntity   new MultipartEntity          reqEntity addPart  fileup0   bin         reqEntity addPart  fileup1   comment          reqEntity addPart  ONE   new StringBody  11111111           reqEntity addPart  TWO   new StringBody  222222222           httppost setEntity reqEntity          System out println  Requesting       httppost getRequestLine           ResponseHandler lt String gt  responseHandler   new BasicResponseHandler          String responseBody   httpclient execute httppost  responseHandler          System out println  responseBody       responseBody          catch  UnsupportedEncodingException e          e printStackTrace          catch  ClientProtocolException e          e printStackTrace          catch  IOException e          e printStackTrace          finally         httpclient getConnectionManager   shutdown                   Added   Example Link

Easy  you can use a Post request and submit your file as binary  byte array    String url    http   yourserver   File file   new File Environment getExternalStorageDirectory   getAbsolutePath             yourfile    try       HttpClient httpclient   new DefaultHttpClient         HttpPost httppost   new HttpPost url        InputStreamEntity reqEntity   new InputStreamEntity              new FileInputStream file   -1       reqEntity setContentType  binary octet-stream        reqEntity setChunked true      Send in multiple parts if needed     httppost setEntity reqEntity       HttpResponse response   httpclient execute httppost         Do something with response       catch  Exception e           show error

the most effective method is to use android-async-http  You can use this code to upload a file      gather your request parameters File myFile   new File   path to file png    RequestParams params   new RequestParams    try       params put  profile picture   myFile     catch FileNotFoundException e         send request AsyncHttpClient client   new AsyncHttpClient    client post url  params  new AsyncHttpResponseHandler          Override     public void onSuccess int statusCode  Header   headers  byte   bytes               handle success response             Override     public void onFailure int statusCode  Header   headers  byte   bytes  Throwable throwable               handle failure response             Note that you can put this code directly into your main Activity  no need to create a background Task explicitly  AsyncHttp will take care of that for you
