Fix for race condition when loading fonts from font provider

            return cachedTypeface;

        }

        // Unfortunately the typeface is not available at this time, but requesting from the font

        // provider takes too much time. For now, request the font data to ensure it is in the cache

        // next time and return.

        synchronized (sLock) {

            // It is possible that Font is loaded during the thread sleep time

            // re-check the cache to avoid re-loading the font

            cachedTypeface = sTypefaceCache.get(id);

            if (cachedTypeface != null) {

                return cachedTypeface;

            }

            // Unfortunately the typeface is not available at this time, but requesting from

            // the font provider takes too much time. For now, request the font data to ensure

            // it is in the cache next time and return.

            if (sHandler == null) {

                sThread = new HandlerThread("fonts", Process.THREAD_PRIORITY_BACKGROUND);

                sThread.start();
