public class MainActivity extends ActionBarActivity {

public Bitmap bitmap; 
public static String exsistingFileName;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Log.d("Tag", "First Log Message");
    InputStream is=getResources().openRawResource(R.drawable.ic_launcher);
    bitmap = BitmapFactory.decodeStream(is); //This gets the image


    ImageView myImageView = (ImageView)findViewById(R.id.myImageView);
    myImageView.setImageBitmap(bitmap);

    try {
        sendData(null);
    } catch (Exception e) {
        e.printStackTrace();
    }


    }



public void sendData(String[] args) throws Exception {  
    try {  

        HttpClient httpClient = new DefaultHttpClient();  
        HttpContext localContext = new BasicHttpContext();  



        HttpPost httpPost = new HttpPost("http://localhost/xampp/UploadToServer.php");  
        MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); 

        Log.d("Tag", "Second Log Message");

        // format of image compressed - 640 x 480;  

        Bitmap bmpCompressed = Bitmap.createScaledBitmap(bitmap, 640, 480, true);  
        ByteArrayOutputStream bos = new ByteArrayOutputStream();  
        Log.d("Tag", "Third Log Message");


        bmpCompressed.compress(CompressFormat.JPEG, 100, bos);  
        Log.d("Tag", "Fourth Log Message");

        byte[] data = bos.toByteArray();  



        entity.addPart("myParam", new StringBody("my value"));  


        entity.addPart("myImage", new ByteArrayBody(data, "temp.jpg")); 

        Log.d("Tag", "Fifth Log Message");

        httpPost.setEntity(entity);  
        Log.d("Tag", "Sixth Log Message");

        HttpResponse response = httpClient.execute(httpPost,localContext);  
        Log.d("Tag", "Seventh Log Message");
        BufferedReader reader = new BufferedReader(new InputStreamReader( response.getEntity().getContent(), "UTF-8"));  
        String sResponse = reader.readLine();  

    } catch (Exception e) {  


       System.out.println(e.getClass().getName());
       Log.v("myApp", "Some error came up");  

    }  

}  

}

它没有在＆＃34;响应＆＃34;中给出任何价值。 以下是与此活动相关的 logcat 信息。
