I’ve been messing around with the FaceDetector and Face classes in Android and can’t seem to get the FaceDetector.findFaces method to populate the faces array with any Face objects in ICS. I have tried running it in a 4.0 emulator and on my Galaxy Nexus running 4.0.2 and the array is never populated with any Face objects. I tried running the same app on a 2.2 emulator and it works perfectly. Did I miss something or is this a bug?

    According to the documentation, the Bitmap has to be in 565 format. To elaborate more, here’s how you should load an image:

        BitmapFactory.Options opts = new BitmapFactory.Options();
    opts.inPreferredConfig = Bitmap.Config.RGB_565;
    Bitmap bmpFindFaces = BitmapFactory.decodeFile("/path/to/image.jpg", opts);

    I thought it was a bug too, because someone reported it. Maybe Google changed something in 4.0 and updated the documentation.
