Android : Is it possible to add animated emoji in android messaging

I am developing an emoji keyboard for android but don't know how to add a animated emoji in currentInputConnection of InputMethodService.

 Edittext content= findVie......
    sb = new SpannableStringBuilder();
            String dummyText = "-";
            sb.append(dummyText);

            try {
                sb.setSpan(anim = new AnimatedImageSpan(new AnimatedGifDrawable(
                        getAssets().open("54.gif"),
                        new AnimatedGifDrawable.UpdateListener() {
                            @Override
                            public void update() {
                                content.requestLayout();
                                content.invalidate();
                            }
                        })), sb.length() - dummyText.length(), sb.length(),
                        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            content.setText(sb);

here content is a editText view but I don"t have any edit text view. All i have is currentInputConnection return by InputMethodService.getCurrentInputConnection.
