Simple image upload to a simple local server from android emulator

Question

I am trying to post a single image to my local server from android

I had tried this here few days ago and with my previous Stackoverflow post here
I was able to get the work done
Today when i retry this i am getting errors again

MainActivity.java

public class MainActivity extends Activity {

    Button submit;
    ProgressDialog pDialog;
    InputStream is;

    ImageView imageView;

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

        submit = (Button) findViewById(R.id.SUBMIT_BUTTON_ID);

        imageView = (ImageView) findViewById(R.id.imageView1);

        submit.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                new MainTest().execute();


            }
        });
    }



    /**
     * Method to post the image to the server.
     * U will have to change the url which will accept the image data.
     * @throws IOException 
     */
    public void postImageData() {


        try
        {

        Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(),R.drawable.ic_launcher); 

        HttpClient httpClient = new DefaultHttpClient();
        HttpPost postRequest = new HttpPost("http://10.0.2.2:7002/Details/");
        MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
        try{
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            bitmapOrg.compress(CompressFormat.JPEG, 75, bos);
            byte[] data = bos.toByteArray();
            ByteArrayBody bab = new ByteArrayBody(data, "forest.jpg");
            reqEntity.addPart("key", bab);
        }
        catch(Exception e){
            //Log.v("Exception in Image", ""+e);
            reqEntity.addPart("picture", new StringBody(""));
        }
        postRequest.setEntity(reqEntity);       
        HttpResponse response = httpClient.execute(postRequest);
        BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
        String sResponse;
        StringBuilder s = new StringBuilder();
        while ((sResponse = reader.readLine()) != null) {
            s = s.append(sResponse);
        }
    }catch(Exception e){
        e.getStackTrace();
    }

















    }
    public class MainTest extends AsyncTask<String, Integer, String> {

        @Override
        protected void onPreExecute() {
            pDialog = new ProgressDialog(MainActivity.this);
            pDialog.setMessage("Loading..");
            pDialog.setIndeterminate(true);
            pDialog.setCancelable(false);
            pDialog.show();
        }

        @Override
        protected String doInBackground(String... params) {

            postImageData();

            return null;
        }

        @Override
        protected void onPostExecute(String result) {
            // TODO Auto-generated method stub

            super.onPostExecute(result);
            // data=jobj.toString();
            pDialog.dismiss();

        }

    }

}

Clearly Caused by: java.lang.NoClassDefFoundError: org.apache.http.entity.mime.MultipartEntity

this class is not available to you in runtime, add Mime jar to lib forlder and add to your build path, this would reolve this issue.

First of all remove that jar file:

And java.lang.NoClassDefFoundError: means you have not properly add jar file to your project. So

After that import that jar file:

Right Click -> Properties -> Java Build path -> Add External Jar-> Apply ->Ok

And also add that jar file to your libs folder.
