Possible fix for https://github.com/koral--/android-gif-drawable/issues/228

Sample.java

Drawable.Callback gifCallback;

private SpannableStringBuilder handleEmotion(final TextView gifTextView, String content) {
    SpannableStringBuilder sb = new SpannableStringBuilder(content);
    String regex = "\\[(.+?)\\]";
    Pattern p = Pattern.compile(regex);
    Matcher m = p.matcher(content);

    if (m.groupCount() > 0) {
        gifCallback = new Drawable.Callback() {

            @Override
            public void invalidateDrawable(Drawable drawable) {
                gifTextView.invalidate();
            }

            @Override
            public void scheduleDrawable(Drawable who, Runnable what, long when) {
                gifTextView.postDelayed(what, when);
            }

            @Override
            public void unscheduleDrawable(Drawable who, Runnable what) {
                gifTextView.removeCallbacks(what);
            }
        };
    }
    while (m.find()) {
        String tempText = m.group(1);
