Android Spanned Text while deleting smiles shows text

Question

I have SpannedText in EditText and I am replacing text with smiles for example cool replaced with smile. But when I am pressing Backspace on android phone (Nexus 5 kitkat 4.4.4) it shows "(Smile)cool" then it deletes the letters at last the smile itself. But on Genymotion emulator it works as needed. What is wrong with my code?

This code is in for

Drawable d = Drawable.createFromStream(ims, null);
                Bitmap b = ((BitmapDrawable)d).getBitmap();
                int spanSmileHeight = (displayHeight>displayWidth) ? ((int) ((double) displayHeight/25)) : ((int) ((double) displayWidth/25));
                int spanSmileWidth = ((int) ((double) spanSmileHeight/b.getHeight())*b.getWidth())+15;
                Bitmap bitmapResized = Bitmap.createScaledBitmap(b, spanSmileWidth, spanSmileHeight, false);
                Drawable sd = new BitmapDrawable(getResources(), bitmapResized);
                sd.setBounds(0, 0, spanSmileWidth, spanSmileHeight);
                addPattern(emoticons, smileyCode, sd);
...

ImageView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        int start = Math.max(message.getSelectionStart(), 0);
                        int end = Math.max(message.getSelectionEnd(), 0);
                        message.getText().replace(Math.min(start, end), Math.max(start, end),
                                smileyCode, 0, smileyCode.length());
                        message.setText(getSmiledText(view.getContext(), message.getText()));
                        message.setSelection(start + smileyCode.length());

and this

public static boolean addSmiles(Context context, Spannable spannable) {
        boolean hasChanges = false;
        for (Map.Entry<Pattern, Drawable> entry : emoticons.entrySet()) {
            Matcher matcher = entry.getKey().matcher(spannable);
            while (matcher.find()) {
                boolean set = true;
                for (ImageSpan span : spannable.getSpans(matcher.start(),
                        matcher.end(), ImageSpan.class))
                    if (spannable.getSpanStart(span) >= matcher.start()
                            && spannable.getSpanEnd(span) <= matcher.end())
                        spannable.removeSpan(span);
                    else {
                        set = false;
                        break;
                    }
                if (set) {
                    hasChanges = true;
                    spannable.setSpan(new ImageSpan(entry.getValue(), ImageSpan.ALIGN_BOTTOM),
                            matcher.start(), matcher.end(),
                            Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                }
            }
        }
        return hasChanges;
    }

    public static Spannable getSmiledText(Context context, CharSequence text) {
        Spannable spannable = spannableFactory.newSpannable(text);
        addSmiles(context, spannable);
        return spannable;
    }

Before bacspace

After backspace(of virtual keyobard) pressed

Then if I want to add 100 smiles, how to be? and that names of smiles taken from the names of files. — Nadir Novruzov, Sep 01 '14 at 07:10
check this http://stackoverflow.com/questions/17251226/remove-whole-spannable-with-backspace a comment suggests subclassing EditText and handle backspace, if icon, and bypass to super if normal text — Yazan, Sep 01 '14 at 07:14
when using setSpan make sure that start == end - 1, this will make your ImageSpan one character long span — pskink, Sep 01 '14 at 07:16
when start==end-1 not all text replaced with smile but only first character. But here (https://code.google.com/p/android/issues/detail?id=42904#c8) I've found that if I change targetSDK to 15 then KEYCODE_DEL is captured and I tried it and it worked. may be this is walktrouhg. — Nadir Novruzov, Sep 01 '14 at 07:36

I have found a way how to prevent this. If we change targetSDK to 15 then smiles are deleted succesfully.
