Issue While setting Chips Programatically

[JChudasama]

Hello,

I am using following method to set the chips programatically for my case

GeneralFunctions >> setChips(...)

I'm getting out of span error on following lines

BitmapDrawable bmpDrawableDummy2 = getBitmapDrawable(context, " ", false, 4, chipPropery);
ssb.setSpan(new ImageSpan(bmpDrawableDummy2), x + c.length(), x + c.length() + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

I dont understand why this dummy part is added, please help me out with this.
