how to change image file name in android studio?

Question

I am downloading an image from URL and displaying on an imageview but the problem is if image name starts with a digit it can't be displayed.

private class DownloadFilesTask extends AsyncTask<String, Void, Bitmap> {
    protected Bitmap doInBackground(String... urls) {

        try {

            URL url = new URL(urls[0]);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            Bitmap myBitmap = BitmapFactory.decodeStream(input);
            return myBitmap;

        } catch (IOException e) {
            e.printStackTrace();
            return null;
        }
    }

    protected void onProgressUpdate(Integer... progress) {

    }

    protected void onPostExecute(Bitmap result) {
        //loading.dismiss();

        String image_name = result.toString();
        if( Character.isDigit(image_name.charAt(0))){

        }
        imageView.setImageBitmap(result);
        imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
    }
}

Only your code will tell the actual solution for the problem — Ümañg ßürmån, Nov 20 '18 at 10:27
i want to change image name inside this code block. if( Character.isDigit(image_name.charAt(0))){ } — zaheer, Nov 20 '18 at 10:31
it should not depend on the image name. The problem is likely somewhere else — Vladyslav Matviienko, Nov 20 '18 at 10:41
I have tested other images from the same URL they worked fine, only images start with a digit not displaying. — zaheer, Nov 20 '18 at 10:49
thank you, the issue is resolved, @VladyslavMatviienko you're right the issue is not due to digit. URL returns null — zaheer, Nov 20 '18 at 11:04

Since code provided is unclear, so this might help you. Use Picasso or Universal Image Loader to load Image on ImageView or save bitmap to sdCard and then load it see https://stackoverflow.com/a/34629526/5057663

this likely should be a comment, not an answer, because it actually *does not answer the question*, while still is usefull – Vladyslav Matviienko Nov 20 '18 at 10:50
@VladyslavMatviienko Upvoted your comment, you're absolutely right. But he can't comment as he has only 15 reps.. He needs atleast 50 to comment :) – Ümañg ßürmån Nov 20 '18 at 12:49
