android unable to upload image to server

I am a neophyte to android.since last couple of days I am facing some problem to send my image to server. I simply have a form that include some textfields and image to be taken from library.Everything is working perfect except image upload.I tried most of tutorials on google.The main problem is logcat is not showing any error.I am unable to track what actually went wrong. This is what I did

I used this code to get Image from galary

 private void showFileChooser() {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
    }

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
            filePath = data.getData();
            try {
                bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
                schoolLogoUpload.setImageBitmap(bitmap);

            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

I wrote this function to send selected image to server

public String getPath(Uri uri) {
        Cursor cursor = getContentResolver().query(uri, null, null, null, null);
        cursor.moveToFirst();
        String document_id = cursor.getString(0);
        document_id = document_id.substring(document_id.lastIndexOf(":") + 1);
        cursor.close();

        cursor = getContentResolver().query(
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
        cursor.moveToFirst();
        String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
        cursor.close();

        return path;
    }


public void uploadMultipart() {
        //getting the actual path of the image
        String path = getPath(filePath);

        //Uploading code
        try {
            String uploadId = UUID.randomUUID().toString();

            //Creating a multi part request
            new MultipartUploadRequest(this, uploadId, UPLOAD_URL)
                    .addFileToUpload(path, "image") //Adding file
                    .setNotificationConfig(new UploadNotificationConfig())
                    .setMaxRetries(2)
                    .startUpload(); //Starting the upload

        } catch (Exception exc) {
            Toast.makeText(this, exc.getMessage(), Toast.LENGTH_SHORT).show();
        }
    }

This is my code to receive my image data at server side

if(Input::hasFile('image')) {
            $file = Input::file('image');
            $destination_path = "uploads";
            $extension = Input::file('image')->getClientOriginalExtension();
            $file_name = str_random(20). "." . $extension;
            Input::file('image')->move($destination_path, $file_name);
        }else{
            return \Response::json([
                "error"=>["message"=>"Please select the college logo"]
            ], 404);

I am assuming you have converted an image to Base64 format. Basically Base64 format converts an image (or encodes an image) to the String format.

* Write an Asynctask that will upload an image to the server for you *

Below is the Asynctask :- 

private class AsyncUploadToServer extends AsyncTask<String, Void, String>
{
    ProgressDialog pdUpload;

    String imageData = "";

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pdUpload = new ProgressDialog(MainActivity.this);
        pdUpload.setMessage("Uploading...");
        pdUpload.show();
    }

    @Override
    protected String doInBackground(String... params)
    {
        imageData = params[0];
        HttpClient httpclient = new DefaultHttpClient();

        // URL where data to be uploaded
        HttpPost httppost = new HttpPost(YOUR_URL_HERE);

        try
        {
            // adding data
            List<NameValuePair> dataToBeAdd = new ArrayList<>();
            dataToBeAdd.add(new BasicNameValuePair("uploadedImage", imageData));
            httppost.setEntity(new UrlEncodedFormEntity(dataToBeAdd));

            // execute http post request
            HttpResponse response = httpclient.execute(httppost);
            Log.i("MainActivity", "Response: " + response);
        }
        catch (ClientProtocolException ex)
        {
            ex.printStackTrace();
        }
        catch (IOException ioe)
        {
            ioe.printStackTrace();
        }
        return "";
    }

    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);
        pdUpload.dismiss();
        Toast.makeText(getApplicationContext(), "Image Uploaded Successfully..!!", Toast.LENGTH_SHORT).show();
    }
}

Hope this will help you. :-)
