I cannot agree with you, Mark. This walks and quacks like a bug specific to Galaxy Nexus. See https://code.google.com/p/android/issues/detail?id=24563 for a related problem. In the nutshell, camera may throw a runtime exception if set previewSize is not correct. But in this device, the list of "supported" sizes is simply incorrect, and in some cases setParameters() results in an exception, but sometimes it pretends to accept the new value. Unfortunately, there is no direct way to find that this was "just for show". When used with setPreviewCallback(), you can see that the size of preview buffer does not match expected width*height*3/2. When used with setPreviewCallbackWithBuffer(), you get buffer == null. BR, Alex Cohn -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
