Use Android Camera Without Surface View

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

Solution 1:

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
    publicvoidonPictureTaken(byte[] data, Camera camera) {
        Log.i(Version.APP_ID, "picture-taken");
    }
});

I've been looking for an answer to this for a while. I found it there, copied here for convenience.

Basically, let's just create a dummy SurfaceView (it works even inside a Service), and use it for Camera functions.

SurfaceViewview=newSurfaceView(this);
c.setPreviewDisplay(view.getHolder());
c.startPreview();
c.takePicture(shutterCallback, rawPictureCallback, jpegPictureCallback);
