サーバーには常に 0KB の画像 test.jpg をアップロードしてください。

ここに写真があります：

だから、私がサーバー上で何を得ているかを見ることができます。

助けや提案をいただければ幸いです。問題が解決することを願っています..

Android コード:

     public class Main extends Activity {

InputStream inputStream;
   @Override
   public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);

    Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.ic_launcher);   
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream); //compress to which format you want.
    byte [] byte_arr = stream.toByteArray();
    String image_str = Base64.encodeBytes(byte_arr);
    ArrayList<NameValuePair> nameValuePairs = new  ArrayList<NameValuePair>();

    nameValuePairs.add(new BasicNameValuePair("image",image_str));

    try{
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://server/uploader2.php");
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        String the_string_response = convertResponseToString(response);
        Toast.makeText(this, "Response " + the_string_response, Toast.LENGTH_LONG).show();
    }catch(Exception e){
          Toast.makeText(this, "ERROR " + e.getMessage(), Toast.LENGTH_LONG).show();
          System.out.println("Error in http connection "+e.toString());
    }
}

public String convertResponseToString(HttpResponse response) throws IllegalStateException, IOException{

     String res = "";
     StringBuffer buffer = new StringBuffer();
     inputStream = response.getEntity().getContent();
     int contentLength = (int) response.getEntity().getContentLength(); //getting content length…..
     Toast.makeText(this, "contentLength : " + contentLength, Toast.LENGTH_LONG).show();
     if (contentLength < 0){
     }
     else{
            byte[] data = new byte[512];
            int len = 0;
            try
            {
                while (-1 != (len = inputStream.read(data)) )
                {
                    buffer.append(new String(data, 0, len)); //converting to string and appending  to stringbuffer…..
                }
            }
            catch (IOException e)
            {
                e.printStackTrace();
            }
            try
            {
                inputStream.close(); // closing the stream…..
            }
            catch (IOException e)
            {
                e.printStackTrace();
            }
            res = buffer.toString();     // converting stringbuffer to string…..

            Toast.makeText(this, "Result : " + res, Toast.LENGTH_LONG).show();
            //System.out.println("Response => " +  EntityUtils.toString(response.getEntity()));
     }
     return res;


}}

およびphpコード...（uploader2.php）

<?php
$base=$_REQUEST['image'];
$binary=base64_decode($base);
header('Content-Type: image/jpg; charset=utf-8');
$file = fopen('test.jpg', 'wb');
fwrite($file, $binary);
fclose($file);
echo 'Image upload complete!!, Please check your php file directory……';
echo "<img src=test.jpg>";
?>

何が問題ですか？
