private ImageScanner mScanner;
private Handler mAutoFocusHandler;
private boolean mPreviewing = true;

static {

        return;

    // Hide the window title.
    //requestWindowFeature(Window.FEATURE_NO_TITLE);
    //getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);


    mAutoFocusHandler = new Handler();

    // Create and configure the ImageScanner; …
