How to get count of images stored in SD card

Issue

I need to calculate the number of images stored in SD card and so i would like to name the images unique like Sample0,Sample1,Sample2,Sample3,etc. Is it Possible?

Solution

It gives the number of images present in the images folder of your SD card:

File dir = new File(Environment.getExternalStorageDirectory()
                + "/images");
        File[] files = dir.listFiles();
        int numberOfImages=files.length;
