Android :: How To Delete Photo Just Taken In Program

I have written a program that uses the Intent for the image capture to get a photo using the application in the phone.

Using MediaStore.EXTRA_OUTPUT, I get a URI to the image, wich converted to a path results in something like "/external/images/media/NN" where NN is the number of the photo.

Now, in my program, after I read and manipulated the image, I want to delete that image.

How should I do that ?

(File image = new File(path); image.delete(); // returns false, so doesn't work)
