Embedding emoji(emoticons images) to custom softkeyboard android

I have created a custom soft Keyboard(IME) where we can add custom emoji.

Whenever i try to add my emoticons to it. it override the last text entered. i mean it dont append the emoticons unless it override it. how can i add emoji to currentInputConnection

for example

i image write  hello image abcimage          ///where image represents emoji

it becomes

i image write hello image image

// and i can add image after space easily or i can repeatedly add images easily .

when i add text it appends to emoji but when i add emoji after entering some text it remove the text and then add it self(emoji image).

Just for testing purpose i put emoji code to shift key

Problem code

else if (primaryCode == Keyboard.KEYCODE_SHIFT) 
        {
        //  this.handleShift();

            //this.mComposing.append(getSmiledText(getApplicationContext(), ":)"));

             ImageGetter imageGetter = new ImageGetter() 
                {
                    public Drawable getDrawable(String source) {
                        Drawable d = getResources().getDrawable(R.drawable.e041);
                        d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
                        return d;
                    }
                };

                Spanned cs = Html.fromHtml("<img src='" + getResources().getDrawable(R.drawable.e041) + "'/>", imageGetter, null);

              //  getCurrentInputConnection().commitText(cs, 1);

               // this.mComposing.append(cs);


            //getCurrentInputConnection().commitText(getSmiledText(getApplicationContext(), ":)"), 1);


             getCurrentInputConnection().beginBatchEdit();


             getCurrentInputConnection().commitText(cs, 1);

             getCurrentInputConnection().endBatchEdit();


            //getCurrentInputConnection().setComposingText(cs, 1); // it is giving wrong 


        }

And tried multiple ways to solve it ,some tried codes are shown in comments
