Image download failed when try to download by using IntentService in Android

Issue

I am trying to download a image by using AsynckTask but it doesn't give an Image. My ProgressBar is showing a progress as long as i keep up the application but do not load the image.

This is the UI design of my application:

MainActivity:

Java

public class MainActivity extends AppCompatActivity {
    ImageView img;
    Button btn;
    EditText edt;
    ProgressBar prb;
    SampleResultReceiver sampleResultReceiver;
    String defalut_url="http://9xmobi.com/image/15580/size/128x128/KAJOL(12)%5B9xmobi.com%5D.jpg";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        img=(ImageView)findViewById(R.id.image_view);
        setContentView(R.layout.activity_main);
        edt=(EditText)findViewById(R.id.urlid);
        btn=(Button)findViewById(R.id.button);
        prb=(ProgressBar)findViewById(R.id.progress);
    }
    public void click(View view){
        Intent intent=new Intent(MainActivity.this,MyIntentServiceActivity.class);
        intent.putExtra("receiver",sampleResultReceiver);
        intent.putExtra("url", TextUtils.isEmpty(edt.getText())?defalut_url:edt.getText().toString());
        startService(intent);
        prb.setVisibility(View.VISIBLE);
        prb.setIndeterminate(true);
    }
    class SampleResultReceiver extends ResultReceiver {
        /**
         * Create a new ResultReceive to receive results.  Your
         * {@link #onReceiveResult} method will be called from the thread running
         * <var>handler</var> if given, or from an arbitrary thread if null.
         *
         * @param handler
         */
        public SampleResultReceiver(Handler handler) {
            super(handler);
        }

        @Override
        protected void onReceiveResult(int resultCode, Bundle resultData) {
            switch (resultCode){
                case MyIntentServiceActivity.DOWNLOAD_ERROR:
                    Toast.makeText(getApplicationContext(), "error in download",
                            Toast.LENGTH_SHORT).show();
                    prb.setVisibility(View.INVISIBLE);
                    break;
                case MyIntentServiceActivity.DOWNLOAD_SUCCESS:
                    String file_path=resultData.getString("file_path");
                    Bitmap bmp= BitmapFactory.decodeFile(file_path);
                if (img!=null&&bmp!=null){
                    img.setImageBitmap(bmp);
                    Toast.makeText(getApplicationContext(),
                            "image download via IntentService is done",
                            Toast.LENGTH_SHORT).show();
                }
                else{
                    Toast.makeText(getApplicationContext(),
                            "error in decoding downloaded file",
                            Toast.LENGTH_SHORT).show();
                }
                    prb.setIndeterminate(false);
                    prb.setVisibility(View.INVISIBLE);

                    break;

            }
            super.onReceiveResult(resultCode, resultData);
        }
    }
}

And My Service Class is...

Java

public class MyIntentServiceActivity extends IntentService {
    public static final int DOWNLOAD_ERROR=10;
    public static final int DOWNLOAD_SUCCESS=11;
    int byteCount=0;
    public MyIntentServiceActivity(){
        super(MyIntentServiceActivity.class.getName());

    }
    @Override
    protected void onHandleIntent(Intent intent) {
        String path=intent.getStringExtra("url");
        final ResultReceiver receiver=intent.getParcelableExtra("receiver");
        Bundle bundle=new Bundle();
        File internal_root= Environment.getExternalStorageDirectory();
        //File new_folder=new File("sdcard0/IntentService_Example");
        //if (!new_folder.exists()){
          //  new_folder.mkdir();
       // }
        File new_file=new File(internal_root,"download_image.jpg");
        try {
            URL url=new URL(path);
            HttpURLConnection connection=(HttpURLConnection)url.openConnection();
            connection.setRequestMethod("GET");
            connection.setDoOutput(true);
            connection.connect();
            int responseCode=connection.getResponseCode();
            if (responseCode!=200)
                throw new Exception("Error in connection");
            InputStream is=connection.getInputStream();
            OutputStream fos=new FileOutputStream(new_file);
           byte[] buffer=new byte[1024];
            int count=0;
            while ((count=is.read(buffer))>0){
                fos.write(buffer,0,count);
            }
            fos.close();
            String file_path=new_file.getPath();
            bundle.putString("file_path",file_path);
            receiver.send(DOWNLOAD_SUCCESS,bundle);
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Where is my mistake here? please point me in the right direction.

Solution

When your sending the Sample Result Receiver instance to Your Service class,Your not sending an object of the sample result receiver class infact Your sending a null pointer to the service class.

You must try doing this.

public void click(View view){
sampleResultReceiver = new SampleResultReceiver();
        Intent intent=new Intent(MainActivity.this,MyIntentServiceActivity.class);
        intent.putParceleableExtra("receiver",sampleResultReceiver);
        intent.putExtra("url", TextUtils.isEmpty(edt.getText())?defalut_url:edt.getText().toString());
        startService(intent);
        prb.setVisibility(View.VISIBLE);
        prb.setIndeterminate(true);
    }
