Add Function

 public void Add(final String claimType, final String Amount, final String Description,  final Bitmap photo)
    {
        class AddImage extends AsyncTask<Void, Void, String> {
            ProgressDialog loading;

            @Override
            protected void onPreExecute() {
                super.onPreExecute();
                loading = ProgressDialog.show(getApplicationContext(), "Please Wait",null, true, true);
            }

            @Override
            protected void onPostExecute(String s) {
                super.onPostExecute(s);
                loading.dismiss();
                Toast.makeText(getApplicationContext(),s,Toast.LENGTH_LONG).show();
            }

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

                HashMap<String, String> data = new HashMap<String,String>();
                data.put(Configs.KEY_TYPE,claimType);
                data.put(Configs.KEY_AMOUNT,Amount);
                data.put(Configs.KEY_IMAGEDESCRIPTION,Description);
                String uploadImage=getStringImage(photo);
                data.put(Configs.KEY_IMAGE,uploadImage);
                data.put(Configs.KEY_TSID,IDFromInfo);
                RequestHandler rh=new RequestHandler();
                String result = rh.sendPostRequest(Configs.ADD_WORKFORCE,data);
                return  result;
            }
        }

        AddImage ru = new AddImage();
        ru.execute(claimType, Amount, Description, photo);  // error
    }

Error

Error:(185, 11) error: method execute in class AsyncTask<Params,Progress,Result> cannot be applied to given types;
required: Void[]
found: String,String,String,Bitmap
reason: varargs mismatch; String cannot be converted to Void
where Params,Progress,Result are type-variables:

Try this way,

        public void Add(final String claimType, final String Amount, final String Description,  final Bitmap photo)
        {        
          new AddImage().execute();
        }

       class AddImage extends AsyncTask<Void, Void, String> {
            ProgressDialog loading;

            @Override
            protected void onPreExecute() {
                super.onPreExecute();
                loading = ProgressDialog.show(getApplicationContext(), "Please Wait",null, true, true);
            }

            @Override
            protected void onPostExecute(String s) {
                super.onPostExecute(s);
                loading.dismiss();
                Toast.makeText(getApplicationContext(),s,Toast.LENGTH_LONG).show();
            }

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

                HashMap<String, String> data = new HashMap<String,String>();
                data.put(Configs.KEY_TYPE,claimType);
                data.put(Configs.KEY_AMOUNT,Amount);
                data.put(Configs.KEY_IMAGEDESCRIPTION,Description);
                String uploadImage=getStringImage(photo);
                data.put(Configs.KEY_IMAGE,uploadImage);
                data.put(Configs.KEY_TSID,IDFromInfo);
                RequestHandler rh=new RequestHandler();
                String result = rh.sendPostRequest(Configs.ADD_WORKFORCE,data);
                return  result;
            }
        }
