Hi,
can you provide more details about your device (android version,
application processor etc)?
It seems your are trying to run multiple camera instances, surface and
preview buffers are not configured.
see below msgs in your logcat,
D/CameraService( 1845): Camera is now busy, you are screwed
D/Camera ( 1822): app passed NULL surface
Since the buffers are not registered, camera app is crashing (I/DEBUG
messages).
Check the camera app and register preview buffers and the surface to
display the images.
