Answer 1

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 [data] 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.

(emphasis and reference to the proper extra name added)

You did not provide EXTRA_OUTPUT, and so you got a small image via the data extra. If you want a full-sized image, use EXTRA_OUTPUT:
