Android: How to get width and height of an image without using JavaX's ImageIO?

Question

Given an image stored in a File object, how would I get the width and height of that image without using the javax.imageio module, since Android does not allow you to use that module?

Answer 1

Use something like this:

BitmapFactory.Options bmpOptions = new BitmapFactory.Options();

bmpOptions.inJustDecodeBounds = true;

BitmapFactory.decodeFile(yourFile, bmpOptions);

bmpOptions will have outWidth and outHeight with your image dimensions.
