Answer 1

Here's my modified version/improvement on @Mr32Bit's answer. On the first call, I copy the font to the app private dir /custom_fonts. Future reads check if exists and if so reads existing copy (saves time on coping file each time).

note: This assumes only a single custom font.

 /**
     * Helper method to load (and cache font in app private folder) typeface from raw dir this is needed because /assets from library projects are not merged in Eclipse
     * @param c
     * @param resource ID of the font.ttf in /raw
     * @return
     */
    public static Typeface loadTypefaceFromRaw(Context c, int resource)
    {
        Typeface tf = null;

        InputStream is = c.getResources().openRawResource(resource);
        String path = c.getFilesDir() + "/custom_fonts";
        File f = new File(path);
        if (!f.exists())
        {
            if (!f.mkdirs())
                return null;
        }

        String outPath = path + "/myfont.ttf";

        File fontFile = new File(outPath);
        if (fontFile.exists()) {
            tf = Typeface.createFromFile(fontFile);
        }else{
            try
            {
                byte[] buffer = new byte[is.available()];
                BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(outPath));
                int l = 0;
                while((l = is.read(buffer)) > 0)
                {
                    bos.write(buffer, 0, l);
                }
                bos.close();
                tf = Typeface.createFromFile(outPath);
            }
            catch (IOException e)
            {
                return null;
            }
        }
        return tf;
    }
