java.lang.IndexOutOfBoundsException: setSpan (-1 ... -1) starts before 0 at Android 8.0

Question

The problem Since the upgrade to Android 8.0 I get many crash reports stating an IndexOutOfBoundsException that occurs outside my code.But different with the other question

The crash report it seems to be a bug in Android itself.But I guess it appeared when I used the link in the content from TextView.

Fatal Exception: java.lang.IndexOutOfBoundsException: setSpan (-1 ... -1) starts before 0

In the source, AccessibilityNodeInfo.java and method setText()，maybe something wrong.but I don't know.I need help.Thanks

 public void setText(CharSequence text) {
        enforceNotSealed();
        mOriginalText = text;
        // Replace any ClickableSpans in mText with placeholders
        if (text instanceof Spanned) {
            ClickableSpan[] spans =
                    ((Spanned) text).getSpans(0, text.length(), ClickableSpan.class);
            if (spans.length > 0) {
                Spannable spannable = new SpannableStringBuilder(text);
                for (int i = 0; i < spans.length; i++) {
                    ClickableSpan span = spans[i];
                    if ((span instanceof AccessibilityClickableSpan)
                            || (span instanceof AccessibilityURLSpan)) {
                        // We've already done enough
                        break;
                    }
                    int spanToReplaceStart = spannable.getSpanStart(span);
                    int spanToReplaceEnd = spannable.getSpanEnd(span);
                    int spanToReplaceFlags = spannable.getSpanFlags(span);
                    spannable.removeSpan(span);
                    ClickableSpan replacementSpan = (span instanceof URLSpan)
                            ? new AccessibilityURLSpan((URLSpan) span)
                            : new AccessibilityClickableSpan(span.getId());
                    spannable.setSpan(replacementSpan, spanToReplaceStart, spanToReplaceEnd,
                            spanToReplaceFlags);
                }
                mText = spannable;
                return;
            }
        }
        mText = (text == null) ? null : text.subSequence(0, text.length());
    }

Answer 1

Try to use string instead of charsequence, and please make sure text value isn't empty

Answer 2

as @chenjian chen mentioned it maybe occur if Talkback is enabled in Settings->Accessibility. I fix this by add android:importantForAccessibility="no" for views that cause this error. in my case, a customView that I make it is reason of crash. so add this line in constructor fixed problem: setImportantForAccessibility(View.IMPORTANT_FOR_ACCESSIBILITY_NO);:
