Image format of pictures taken with the camera (Android phones)

Question

For my app I have to send a mail with a photo (I'm using a webservice to do that).

I'd like to know if there are some Android phones that does not produce jpg file with the camera (such as png file).

Solution

I think every device should support JPEG images, because the description of the

takePicture (Camera.ShutterCallback shutter, Camera.PictureCallback raw, Camera.PictureCallback postview, Camera.PictureCallback jpeg)

method says that only raw and postview callbacks may be null.

On the other side, you may always call

camera.getParameters().getSupportedPictureFormats()

to see what picture formats are supported.
