You could try using the HTTPS protocol instead of the HTTP protocol, as described here.

I switched my hosting provider from Hostinger to Digital Ocean Spaces, the files are the same, only the url is different.

Playing the hosted mp3 file with media player still works with the new URL but downloading it doesn’t.

I get the following crash:

    java.io.FileNotFoundException: https://myapp-content.ams3.digitaloceanspaces.com/MyApp/sounds/b9a14d77-d122-4bd9-9f2d-5dd7ad9b90ee.mp3

The link is working (not the one I posted here) even if I access it in inkognito, i can also download the sound in chrome.
But somehow the downloading process in my app doesnt work with the mp3 files hosted on Digital Ocean.
Any Ideas?

This line is causing the problem:

InputStream inputStream = urlConnection.getInputStream();

With the old hosting provider I’m getting status code 200, with the new one 400

Here is the whole download Function:

try {
                URL url = new URL(filePath);
                HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
                urlConnection.setRequestMethod("GET");
                urlConnection.setDoOutput(true);
                urlConnection.connect();

                File storage = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
                File directory = new File(storage.getAbsolutePath());
                directory.mkdirs();


                String fileNameWithoutSpecialCharacters = fileName.replaceAll("\W", "");
                file = new File(directory, fileNameWithoutSpecialCharacters + ".mp3");

                FileOutputStream fileOutput = new FileOutputStream(file);

                Log.i("download:", "Code: " + urlConnection.getResponseCode());
                InputStream inputStream = urlConnection.getInputStream();

                totalSize = urlConnection.getContentLength();

                int downloadedSize = 0;

                byte[] buffer = new byte[1024];

                int bufferLength = 0; //used to store a temporary size of the buffer

                while ((bufferLength = inputStream.read(buffer)) > 0) {
                    fileOutput.write(buffer, 0, bufferLength);
                    downloadedSize += bufferLength;
                    Log.i("download:", downloadedSize + "/" + totalSize);
                }

                fileOutput.close();
                ClipboardManager clipboard = (ClipboardManager) MainActivity.mainActivityWeakReference.get().getSystemService(Context.CLIPBOARD_SERVICE);
                ClipData clip = ClipData.newPlainText("test", "test");
                clipboard.setPrimaryClip(clip);

            } catch (IOException e) {
                e.printStackTrace();
                ClipboardManager clipboard = (ClipboardManager) MainActivity.mainActivityWeakReference.get().getSystemService(Context.CLIPBOARD_SERVICE);
                ClipData clip = ClipData.newPlainText("test", e.toString());
                clipboard.setPrimaryClip(clip);
            }
