OpenCV Android Getting Front Camera From JavaCameraView (Bug #2839)

On certain devices (especially tablets) there is only a front-facing camera. Therefore, choosing 1 as the camera index will result in an error (since there is only 1 camera, it will be 0). My proposed solution is that if mCameraIndex is set to 1 check the CameraInfo to find the front-facing camera (if there is one). I have tested this with devices that only have a front camera, and it works. This proposal is based off of the 2.4.4 beta, in JavaCameraView.java, method initializeCamera:

if (mCameraIndex == -1) {
                Log.d(TAG, "Trying to open camera with old open()");
                try {
                    mCamera = Camera.open();
                }
                catch (Exception e){
                    Log.e(TAG, "Camera is not available (in use or does not exist): " + e.getLocalizedMessage());
                }

if(mCamera == null && Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
                    boolean connected = false;
                    for (int camIdx = 0; camIdx < Camera.getNumberOfCameras(); ++camIdx) {
                        Log.d(TAG, "Trying to open camera with new open(" + Integer.valueOf(camIdx) + ")");
                        try {
                            mCamera = Camera.open(camIdx);
                            connected = true;
                        } catch (RuntimeException e) {
                            Log.e(TAG, "Camera #" + camIdx + "failed to open: " + e.getLocalizedMessage());
                        }
                        if (connected) break;
                    }
                }
            } else {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
                    Log.d(TAG, "Trying to open camera with new open(" + Integer.valueOf(mCameraIndex) + ")");
                    //here is where the proposed solution begins
                    if(mCameraIndex == 1) {
                        int count = 0;
                        Camera.CameraInfo cInfo = new Camera.CameraInfo();
                        count = Camera.getNumberOfCameras();

for(int i = 0; i < count; i++) {
                            Camera.getCameraInfo(i, cInfo);
                            if(cInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
                                try {
                                    mCamera = Camera.open(i);
                                    break;
                                 } catch(Exception e) {
                                    Log.e(TAG, "Camera #" + mCameraIndex + "failed to open: " + e.getLocalizedMessage());
                                    break;
                                }
                            }
                        }
                    }
                    else {
                        try {
                            mCamera = Camera.open(mCameraIndex);
                        } catch (RuntimeException e) {
