Answer 1

You can access Front camera by

Camera.CameraInfo.CAMERA_FACING_FRONT

and here is the example method you can use to access it

private Camera openFrontFacingCameraGingerbread() {
int cameraCount = 0;
Camera cam = null;
Camera.CameraInfo cameraInfo = new Camera.CameraInfo();
cameraCount = Camera.getNumberOfCameras();
for (int camIdx = 0; camIdx < cameraCount; camIdx++) {
    Camera.getCameraInfo(camIdx, cameraInfo);
    if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
        try {
            cam = Camera.open(camIdx);
        } catch (RuntimeException e) {
            Log.e(TAG, "Camera failed to open: " + e.getLocalizedMessage());
        }
    }
}

return cam;
}
