Quoting the documentation for ACTION_IMAGE_CAPTURE:

The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. This is useful for applications that only need a small image. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT.

You are using EXTRA_OUTPUT. Hence, data.getExtras().get("data") will not work. There does not have to even be a data Intent delivered to you if you are using EXTRA_OUTPUT.

Instead, the image should be written to the location that you provided to EXTRA_OUTPUT.
