Answer 1

For lower API levels you could use:

private void setCameraDisplayOrientationAPI8(){
        //Sets the camera right Orientation.
        //Special void for API 8 build.
        //This void should be called before calling camera.setParameters(cameraParameters).
        if (activeActivity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT)
        {   
            camera.setDisplayOrientation(90);
        }
        if (activeActivity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)
        {                               
            camera.setDisplayOrientation(180);
        }
    }

and just call setCameraDisplayOrientationAPI8(); on your surfaceChanged func.

plus:

private void setCameraDisplayOrientation() {
        //Sets the camera right Orientation.
        //IMPORTANT!! This code is available only for API Level 9 build or greater.
        if (mApiLvl<9){
            Log.d(TAG, "setCameraDisplayOrientation ERROR: This code is available only for API Level 9 build or greater.");
            return;
        }
        android.hardware.Camera.CameraInfo info =
                new android.hardware.Camera.CameraInfo();
        android.hardware.Camera.getCameraInfo(cameraIndex, info);
        int rotation = activeActivity.getWindowManager().getDefaultDisplay()
                .getRotation();
        int degrees = 0;
        switch (rotation) {
            case Surface.ROTATION_0: degrees = 0; break;
            case Surface.ROTATION_90: degrees = 90; break;
            case Surface.ROTATION_180: degrees = 180; break;
            case Surface.ROTATION_270: degrees = 270; break;
        }

        int result;
        if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
            result = (info.orientation + degrees) % 360;
            result = (360 - result) % 360;  // compensate the mirror
        } else {  // back-facing
            result = (info.orientation - degrees + 360) % 360;
        }
        camera.setDisplayOrientation(result);
    }

hope this helps.
