Save Media Files to SharedPreferences/Files Android

Question

I want to download and save a.ttf or.otf file for custom fonts in my Android App. Is it possible to save this in SharedPreferences?

Not the file path, but the file itself.

Edit: I asked for this method because OutputStream kept giving me 'Permission Denied' error. I am open to any suggestion that would help me save the downloaded.ttf to files and retrieve it later.

Thanks!

Edit: I have added the Input Output Stream code below, which gives me a permission denied error when running. Please let me know if I can fix something here.

class DownloadFileFromURL extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... f_url) {
    int count;
    try {
        URL url = new URL(f_url[0]);
        URLConnection connection = url.openConnection();
        connection.connect();
        // this will be useful so that you can show a typical 0-100% progress bar
        int lenghtOfFile = connection.getContentLength();

        InputStream input = new BufferedInputStream(url.openStream(), 8192);
        File file = new File(Environment.getExternalStorageDirectory(), "downloadedFont.ttf");
        OutputStream output = new FileOutputStream(file);

        byte data[] = new byte[1024];
            long total = 0;
            while ((count = input.read(data)) != -1) {
                total += count;
                publishProgress(""+(int)((total*100)/lenghtOfFile));
                output.write(data, 0, count);
            }
            output.flush();
            output.close();
            input.close();

    } catch (Exception e) {
        Log.e("Error", e.getMessage() + e.getCause());
    }
    return null;
}

@Override
protected void onPostExecute(String file_url) {
    loadFont();
}

public static void loadFont() {
    File file = new File(Environment.getExternalStorageDirectory().toString() + "/downloadedFont.ttf");
    if(file.exists()){
        Log.d("LOAD", "File exists");
        Typeface typeFace = Typeface.createFromFile(file);
        ContextHelper.setDownloadedFontType(typeFace);
    }
    else {
        download();
    }
}

public static void download() {
    Log.d("DOWNLOAD", "In the download.");
    new DownloadFileFromURL().execute("https://www.dropbox.com/s/y980vywiprd8eci/riesling.ttf?raw=1");
}
}

The following is how the method is called in an Activity.

DownloadFileFromURL.loadFont();

Answer 1

I thought that's possible. Download File first convert to Base64 Encoding save that encoding data in Share Pref. When you Fetch it Decoding and create a file again and use it.

Answer 2

After much searching, I found the answer in the depths of StackOverflow:

public static void downloadFont(String url, Context context) {
    DownloadManager.Request request1 = new DownloadManager.Request(Uri.parse(url));
    request1.setDescription("Sample Font File");
    request1.setTitle("Font.ttf");
    request1.setVisibleInDownloadsUi(false);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        request1.allowScanningByMediaScanner();
        request1.setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN);
    }
    request1.setDestinationInExternalFilesDir(context, "/File", "Font.ttf");

    DownloadManager manager1 = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
    Objects.requireNonNull(manager1).enqueue(request1);

    if (DownloadManager.STATUS_SUCCESSFUL == 8) {
        File file = new File(context.getExternalFilesDir("/File").toString() + "/Font.ttf");
        if(file.exists()){
            Typeface typeFace = Typeface.createFromFile(file);
        }
    }
}

Many thanks to this answer which helped solve my problem so concisely.
