Get filepath and filename of selected gallery image in Android

Question

I am creating an app which uploads a selected image from the gallery and uploads it to a web service. The webservice requires the filename of selected image plus a base64 encoding of the file contents. I have managed to achieve this with a hardcoded file path. However, I am struggling to get the real filepath of the image. I have read around the web and have this code, but it does not work for me:

 public void onActivityResult(int requestCode, int resultCode, Intent data) {    if (resultCode == RESULT_OK) {      Uri selectedImageUri = data.getData();      String[] projection = {MediaStore.Images.Media.DATA};       try {        Cursor cursor = getContentResolver().query(selectedImageUri, projection, null, null, null);        cursor.moveToFirst();         int columnIndex = cursor.getColumnIndex(projection[0]);        String picturePath = cursor.getString(columnIndex);        cursor.close();        Log.d("Picture Path", picturePath);      }      catch(Exception e) {        Log.e("Path Error", e.toString());      }    }  } 

I get this error:

java.lang.NullPointerException 

EDIT

Forgot to mention I am using Kitkat. It looks like my problem is KitKat related. I found this (see below) which helped me get my app working:

Android Gallery on KitKat returns different Uri for Intent.ACTION_GET_CONTENT

Add this class in your project

ImageFilePath.java

In your onActivityResult

 @Override     public 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) {              Uri uri = data.getData();               realPath = ImageFilePath.getPath(SignupActivity.this, data.getData()); //                realPath = RealPathUtil.getRealPathFromURI_API19(this, data.getData());              Log.i(TAG, "onActivityResult: file path : " + realPath);             try {                 Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);                 // Log.d(TAG, String.valueOf(bitmap));                  ImageView imageView = (ImageView) findViewById(R.id.img_profile);                 imageView.setImageBitmap(bitmap);                 imageView.setVisibility(View.VISIBLE);              } catch (IOException e) {                 e.printStackTrace();             }         } else {             Toast.makeText(this, "Something Went Wrong", Toast.LENGTH_SHORT).show();         }      }
