public void capturePhoto(View view) {
    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    File photoFile = new File(Environment.getExternalStorageDirectory(),  "Photo.png");
    intent.putExtra(MediaStore.EXTRA_OUTPUT,

                Uri selectedImageUri = imageUri;
                //Do what ever you want
        }
    }
