[android-developers] Camera preview sizes on Galaxy Nexus (ICS)

The camera of Galaxy Nexus (software v. 4.0.2) reports preview-size-values=1920x1080,1280x720,960x720,800x480,720x576,720x480,768x576,640x480,320x240,352x288,240x160,176x144,128x96; and really, it is possible to set Parameters.setPreveiwSize(320, 240) and after that Camera.getParameters().getPreviewSize() will return 320x240.

The problem is that the camera itself seems to silently ignore this setting: onPreviewFrame() callback arrives with preview buffer of 460800 bytes and contains a VGA preview (640x480).

This looks like a bug in Galaxy Nexus, but also exposes a problem with the Camera API of Android: there is no way for Camera.setParameters() to fail or report anything about parameters inconsistency.

Sincerely,
Alex
