Initiate Camera Intent with the Gallery Icon

Question

I am working on an app that accesses the camera and returns an uri, which I pass to another activity and display the extracted bitmap in an ImageView. Everything seems to work fine. Here is the code that I use to initiate the camera intent.

mCameraButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mCameraUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, new ContentValues());
            Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mCameraUri);
            mtimeCameraAcessed = System.currentTimeMillis();
            startActivityForResult(cameraIntent, RECEIVE_CAMERA_PICTURE);
            overridePendingTransition(R.anim.slide_in_right, R.anim.slide_out_left);

        }

});

But, I have noticed a discrepancy. When my application access the camera, the gallery icon at the bottom of the screen seems to be missing (the icon appears when you access the camera application on any android phone). I have attached a couple of screenshots to illustrate this.

I want the user to access the camera while being able to change his/her mind and then access the gallery on the same screen (by tapping the gallery icon). Now, I do know how to initiate a gallery intent via 'Intent.ACTION_PICK'. I have also looked at the this question, but I don't completely agree that I need a custom camera layout to achieve what I intend to do: Single intent to let user take picture OR pick image from gallery in Android

The reason I say this is because, I have seen apps such as QuickPic that access the camera application with the gallery icon at the bottom. Can anyone please throw some light on this?
