I'm developing on android, i want to do somethings with camera (process pixels's values), but just in background, is it possible to do it without surface view? just use a buffer to read pixels's values and do processing. thanks for every one can help me

As of API-Level 11 the SurfaceTexture was added. With it a SurfaceView is no longer needed. I tested the following code with my Samsung Galaxy S3 Neo.

mCamera = Camera.open();
try {
    mCamera.setPreviewTexture(new SurfaceTexture(10));
} catch (IOException e1) {
    Log.e(Version.APP_ID, e1.getMessage());
}

Parameters params = mCamera.getParameters();
params.setPreviewSize(640, 480);
params.setFlashMode(Camera.Parameters.FLASH_MODE_OFF);
params.setPictureFormat(ImageFormat.JPEG);
mCamera.setParameters(params);
mCamera.startPreview();
mCamera.takePicture(null, null, null, new PictureCallback() {
    @Override
    public void onPictureTaken(byte[] data, Camera camera) {
        Log.i(Version.APP_ID, "picture-taken");
    }
});
