Android Question [Solved] Problems to save a bitmap in different formats

I want to save a bitmap (create from a panel) in WEBP format and a size of 512x512 (OK), but don't works.

So, I tried with differents formats and has problems in others formats, except JPEG.

This is my code and my project is in attached.

This is the problems:

- JPG : OK


- PNG : cut the image / size 512x512 OK
(couldn't attach in the post)

- WEBP : cut the image / size 512x512 OK / don't open in the computer (GIMP)

- WEBP (converted from a PNG image) : cut the image / size 512x512 OK / don't open in the computer (GIMP)
(couldn't attach in the post = zip file)

Project in attached too.

I don't know what I'm doing wrong.

Thanks in advance for any tip.
