Android startActivityForResult trying to fecth Image from Gallery Error

Question

I am trying to get image from gallery and this is my code.

 mProfilePic.setOnClickListener(new View.OnClickListener() {
             @Override
             public void onClick(View v) {
                 Intent i = new Intent(
                         Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                 startActivityForResult(i, RESULT_LOAD_IMAGE);//Result_Load_Image =1
             }
         });



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

        if ( resultCode == RESULT_OK && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = {MediaStore.Images.Media.DATA};

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

            Bitmap bm =BitmapFactory.decodeFile(picturePath);
            Bitmap resized = Bitmap.createScaledBitmap(bm, 100, 100, true);
            mProfilePic.setImageBitmap(ProfilePicture.addPicture(resized));

        }


    }

and this my ImageConvertor code

    public class ProfilePicture {
    public static Bitmap getRoundedRectBitmap() {
        Bitmap result = null;
        try {
            result = Bitmap.createBitmap(200, 200, Bitmap.Config.ARGB_8888);
            Canvas canvas = new Canvas(result);

            int color = 0xff424242;
            Paint paint = new Paint();
            Rect rect = new Rect(0, 0, 200, 200);

            paint.setAntiAlias(true);
            canvas.drawARGB(0, 0, 0, 0);
            paint.setColor(color);
            canvas.drawCircle(50, 50, 50, paint);
            paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));




        } catch (NullPointerException e) {
        } catch (OutOfMemoryError o) {
        }
        return result;
    }



      public static Bitmap addPicture(Bitmap bitmap){
          Bitmap result = null;
          try {
              result = Bitmap.createBitmap(200, 200, Bitmap.Config.ARGB_8888);
              Canvas canvas = new Canvas(result);

              int color = 0xff424242;
              Paint paint = new Paint();
              Rect rect = new Rect(0, 0, 200, 200);

              paint.setAntiAlias(true);
              canvas.drawARGB(0, 0, 0, 0);
              paint.setColor(color);
              canvas.drawCircle(50, 50, 50, paint);
              paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));

          } catch (NullPointerException e) {
          } catch (OutOfMemoryError o) {
          }
          return result;
      }

}

This is my log

Your problem is when you get a Bitmap's width at somewhere in your code.

NullPointerException:

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference

try this code onActivityresult

Bitmap bitmap = null;

    if (requestCode == GALLERY_CODE && responseCode == RESULT_OK && null != intent) {
        Uri uri = intent.getData();
        mImageCaptureUri = intent.getData();
        System.out.println("Gallery Image URI : "+mImageCaptureUri);
        try {
            bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
            mProfilePic.setImageBitmap(bitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }


    }
