Remove extra space from Android spannable

gistfile1.java

    private void setText(String html) {
        SpannableStringBuilder spanned = (SpannableStringBuilder) Html.fromHtml(html);
        spanned = trimSpannable(spanned);
        mTextView.setText(spanned, TextView.BufferType.SPANNABLE);
    }

    private SpannableStringBuilder trimSpannable(SpannableStringBuilder spannable) {
        checkNotNull(spannable);
        int trimStart = 0;
        int trimEnd = 0;

        String text = spannable.toString();

        while (text.length() > 0 && text.startsWith("\n")) {
            text = text.substring(1);
            trimStart += 1;
        }

        while (text.length() > 0 && text.endsWith("\n")) {
            text = text.substring(0, text.length() - 1);
            trimEnd += 1;
        }

        return spannable.delete(0, trimStart).delete(spannable.length() - trimEnd, spannable.length());
    }

thanks.. its is awsom'

Doesn't that have a problem when it deletes from front and from the end?
spannable.length() will still have the old value when the new one is actually shorter already from having removed from the start.

Works perfectly...
