How to obtain bitmap from camerapreview and draw on canvas

Postby androiduser123 » Sat May 16, 2009 12:22 pm

Hi there,

Please let me know how to obtain bitmap from camerapreview? I tried using onPictureTaken(byte[] data, Camera camera) of PictureCallback and decoding data using BitmapFactory.decodeByteArray.

I then displayed using canvas.

I ran successfully in emulator but on G1 device it is displaying a blank screen.
Please help.

I also have same problem.

I would like to render something on camera screen, something like arrows or some controls.

Like in this application for barcode scanner:
