    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    //Teksti qe tregon qe kliko ne te per te kalu ne aktivitetin tjeter "Toast"
    Toast.makeText(getApplicationContext(), "Press The Photo For Customize", Toast.LENGTH_LONG).show();

    //Merr intentin
    Intent intent = getIntent();

    //Vendos tekstin emrin se kush e ka ditelindjen
    String message = intent.getStringExtra(MESSAGE_KEY);
    TextView textView = (TextView) findViewById(R.id.nameChange);
    textView.setText(message);

    // Vendos tekstin From
    String message1 = intent.getStringExtra(MESSAGE_KEY1);
    TextView textView1 = (TextView) findViewById(R.id.FromName);
    textView1.setText(message1);

    // Vendos Foton
    Bundle extras = getIntent().getExtras();
    if (extras == null) {
        return;
    }
    int res = extras.getInt("resourseInt");
    ImageView view = (ImageView) findViewById(R.id.cakeView);

    view.setImageResource(res);

    //vendos foton qe vjen nga galeria
    File picture = (File) getIntent().getExtras().get("image_path");
    if (picture != null) {
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inSampleSize = 3;

        Bitmap bitmap = BitmapFactory.decodeFile(String.valueOf(picture), options);

        try {
            // Jepja orientimin
            ExifInterface exif = new ExifInterface(String.valueOf(picture));
            int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);

            // Determine Rotation
            int rotation = 0;
            if (orientation == 6) rotation = 90;
            else if (orientation == 3) rotation = 180;
            else if (orientation == 8) rotation = 270;

            // ktheje nqs eshte e detyrueshme
            if (rotation != 0) {
                // Create Matrix
                Matrix matrix = new Matrix();
                matrix.postRotate(rotation);

                // Rotate Bitmap
                Bitmap rotated = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);

                // Pretend none of this ever happened!
                bitmap.recycle();
                bitmap = rotated;
                rotated = null;
            }
        } catch (Exception e) {

        }
        view.setImageBitmap(bitmap);
    }
