EDIT: This is deprecated since API level 21.

Use the Camera.Size nested class

From the android reference:

http://developer.android.com/reference/android/hardware/Camera.html

Class Overview

The Camera class is used to set image capture settings, start/stop preview, snap pictures, and retrieve frames for encoding for video. This class is a client for the Camera service, which manages the actual camera hardware.

Make sure that the size is supported by the camera (and most probably it won't). If not, take a picture at the closest resolution and crop it or resize it.

Camera myCamera = Camera.open(0);
List<Camera.Size> sizes = myCamera.getPArameters().getSupportedPictureSizes();
