Is there is any setting needed? my code :

 public class upload extends Activity {
 InputStream is;
 @Override
 public void onCreate(Bundle icicle) {
 super.onCreate(icicle);
 setContentView(R.layout.main);
 Bitmap bitmapOrg = BitmapFactory.decodeFile("/sdcard/imageq.png");
 ByteArrayOutputStream bao = new ByteArrayOutputStream();
 bitmapOrg.compress(Bitmap.CompressFormat.PNG, 90, bao);
 byte [] ba = bao.toByteArray();
 String ba1=Base64.encodeBytes(ba);
 ArrayList<NameValuePair> nameValuePairs = new
 ArrayList<NameValuePair>();
 nameValuePairs.add(new BasicNameValuePair("image",ba1));
 try{
  HttpClient httpclient = new DefaultHttpClient();
  HttpPost httppost = new HttpPost("http://xxxxxxxxxx/xxxxxx/upload.php");
  httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
  HttpResponse response = httpclient.execute(httppost);
  Log.e("uri",""+httppost.getURI());
  Log.e("response",""+response);
  HttpEntity entity = response.getEntity();
  is = entity.getContent();
  Log.e("is",""+is);
 }catch(Exception e){
Log.e("log_tag", "Error in http connection "+e.toString());
 }
}
}

i get the above code from http://blog.sptechnolab.com/2011/03/09/android/android-upload-image-to-server/
my log cat information:

05-11 10:09:39.488: ERROR/uri(1894): http://xxxxxxxxxx/xxxxxx/upload.php
05-11 10:09:39.488: ERROR/response(1894):    org.apache.http.message.BasicHttpResponse@44f73610
05-11 10:09:39.495: ERROR/is(1894): org.apache.http.conn.EofSensorInputStream@44f1fc88

i print the getURI it returns what i give in the httppost = new HttpPost(“….”). this is not real response from server. please help me.

I am using this code to upload image from device to php server by post method in this code you find a FilsUploader constructor pass file name you want upload and destination url (PHP server Url) for uploading file .I hope this is help.
