具体Error的UI如下面的图片所示：

分析可能是QN 的对话框中手机号码的长度过长导致的问题
解决方案如下：

            contentView.setCharSequence(R.id.status_bar_latest_event_content,
                    "setConversationTitle", conversationTitleNew);
            if (isConversationLayout) {
                contentView.setIcon(R.id.status_bar_latest_event_content,
                        "setShortcutIcon", mShortcutIcon);

                        "setIsImportantConversation", isImportantConversation);
            }
            if (isHeaderless) {
                // Collapsed legacy messaging style has a 1-line limit.
                contentView.setInt(R.id.notification_messaging, "setMaxDisplayedLines", 1);
            }
}

其中关键处理是对号码的长度做截取处理：

if (ZebraUtils.isZebra().orElse(false) && ZebraUtils.isMediumDisplay().orElse(false) && conversationTitle.length()>=7){
                conversationTitleNew = conversationTitle.subSequence(0,7) + ".";
            }else{
                conversationTitleNew = conversationTitle;
            }

修改后的效果如下：
