добавить пользовательское изображение как Emoji в Android

как добавить пользовательское изображение в качестве смайликов в Android InputMethodService. я пытался использовать

ImageGetter imageGetter = new ImageGetter() {
                public Drawable getDrawable(String source) {    
                    StringTokenizer st = new StringTokenizer(str, ".");
                    Drawable d = new BitmapDrawable(getResources(),emoticons[Integer.parseInt(st.nextToken()) - 1]);
                    d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
                    return d;
                }
            };

            Spanned cs = Html.fromHtml("<img src ='"+ str +"'/>", imageGetter, null);


        getCurrentInputConnection().commitText(cs,1);

но только получая текстовое изображение obj. есть ли способ добавить пользовательский смайлик в сообщение (whatsapp / twitter) в android

Изменить:

в моем приложении, если я набираю приветствие с помощью своей пользовательской клавиатуры, мне нужно вставить собственное изображение приветствия в поле редактирования для каждого приложения, установленного в телефоне.

может это достигнуто?

Я также проверил это с помощью конвертации мага в base64, но ничего не происходит с тегом

ImageGetter imageGetter = new ImageGetter() {
                @Override
                public Drawable getDrawable(String source) {    
                    byte [] encodeByte=Base64.decode("iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==",Base64.DEFAULT);
                    Bitmap bitmap=BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);      
                    Drawable d = new BitmapDrawable(bitmap);

                    Log.e("Chk", "Height : "+d.getIntrinsicHeight());
                    Log.e("Chk", "Width : " + d.getIntrinsicWidth());                       

                    return d;
                }
            };

            Spanned cs = Html.fromHtml("<img src='data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='/>", imageGetter,null);

            Log.e("Chk", "12 : " + 12);


        getCurrentInputConnection().setComposingText(cs,1);
