Question

When I save the image to the sdcard it automatically saves it with the given file name. If a file with the same name already exist, it is replaced.

I want to store the images with file names in a sequence where if the file Image exists it will be saved with image1 next image2 and so on.

Please advise how to do that, as I am new to programming.

Answer 1

File fileDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
File[] images = fileDir.listFiles(new FilenameFilter(){
    public boolean accept(File file, String name){
        if(name,toLowerCase().startsWith("image"));
        return true;
        else return false;
    }});

File fileToSave;

if(images.length > 0)
fileToSave = new File(fileDir.getAbsolutePath(), "image" + images.length);
else
fileToSave = new File(fileDir.getAbsolutePath(), "image");

something like that’ll do.
