Checking a camera or image for pixel size

So I was following this tutorial and it says on the tutorial that it assumes the image is 300px x 300px. How do I figure out how large my image is in terms of px when I have just gotten the image from the camera on the phone (not through an instance if that matters).

The example referenced in the question is opening an existing Bitmap image from the application's resources like this:

Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(),R.drawable.image);

How To Get Android Image Bitmap Size

You can determine the width and height of this or any Bitmap with getWidth() and getHeight() as below:

int width = bitmapOrg.getWidth();
int height = bitmapOrg.getHeight();

The complete documentation for Bitmap is here.

Regarding the 300x300 pixel size, the example is forcing those sizes and creating a new Bitmap with the hardcoded values, as below:

int targetWidth = 300;
int targetHeight = 300;
Bitmap targetBitmap = Bitmap.createBitmap(targetWidth, targetHeight,Bitmap.Config.ARGB_8888);
