Google Assistant 此前已经能够读取通过原生短信或者 Hangouts 应用发送给你的 SMS 短信，而现在该语音助手能读取来自 WhatsApp、Telegram、Slack、Discord、GroupMe 等即时通讯软件的大量信息。想要尝试这项操作，向 Assistant 说“read my messages”（读取我的信息）就可以了。如果尚未安装，则必须授予 Google 应用通知权限，此功能才能正常运行。
在收到这条语音命令之后，Google Assistant 就会弹出最近收到的一条信息并大声朗读，朗读的内容包括应用程序和发件人的姓名。然后，您可以选择输入或要求回复。完成后，将立即发送回答并将原始消息标记为已读（通知消失）。Assistant 会逐个读取近期收到的信息内容，不过需要注意的是，Assistant 无法读取包含图片、视频和音频的信息。 Assistant 只会说“该信息中包含音频附件”，但不会播放。
前提是需要授权，如下图：
The reporter learned from the National Space Administration that just now, chang'e-5 probe successfully landed in the pre selected landing area of the front of the moon, becoming the third successful lunar soft landing probe in China. After the successful landing, the lander will officially start working on the lunar surface for about two days under the control of the ground.
On the evening of December 1, local time, the European Space Agency (ESA) shared the news of the successful landing of chang'e-5 probe in the lunar frontal pre selected landing area on social media, and congratulated the Chinese national space agency. ESA also said that through its global tracking station network, ESA provided technical support for the chang'e-5 probe.
After the launch of chang'e-5, it was tracked for hours by ESA's kuru ground station in French Guiana. When chang'e-5 returns to earth, ESA will receive signals through the Maspalomas ground station in Spain.
According to the people's daily of China, the flight control team of the chang'e-5 mission has successfully carried out the separation of the lander and the ascent combination of the chang'e-5 probe with the orbiter and reentry vehicle as planned.
At 4:40 am today, under the precise control of scientific and technological personnel, the chang'e-5 probe assembly was successfully separated.
It is reported that the systems of chang'e-5 probe are in good condition, and the ground TT & C communication is normal. The orbiter and the reentrant combination will continue to fly in the lunar orbit with an average height of about 200 km and wait for the rendezvous and docking of the ascender. The lander and the ascent combination will select an aircraft to implement the lunar soft landing and carry out the follow-up work such as automatic sampling.
The landing site will be a storm ocean in the northwest of the moon. Storm ocean is the largest moon sea on the moon, where human probes have never been before. The storm ocean is a younger region with an age of 3.2 billion to 4 billion years, compared with the quiet sea and the rich sea where human beings have obtained lunar samples.
According to the official news of Beidouxingtong, the subsidiary companies of Beidouxingtong and Xinxingtong have officially released the latest generation of full-system full-frequency centimeter-level high-precision GNSS chips-Hexin Nebulas IV.
According to reports, this chip represents the highest level of domestic satellite navigation chips, has groundbreaking significance in the field of centimeter-level high-precision positioning, and has a leading advantage in the world. While the Nebulas IV chip is iteratively evolving to 22nm, it is the first to realize the integration of baseband + radio frequency + high-precision algorithm on a single chip, supports on-chip RTK, meets the requirements of vehicle regulations, and has better performance, size, and power consumption. The previous generation of chips made breakthroughs to meet the needs of popular applications and better meet the needs of high-end applications such as smart driving and drones.
Various applications based on Beidou will go global with the opening of Beidou system global services. Nebulas IV supports all satellite navigation systems and frequencies in the world, including the latest Beidou III B1C, B2a, and B2b, which will provide a better positioning experience for the broader international market.
pod install 相关类库，尤其update的时候 默认的github太慢了。部分博客指出的清华镜像现在也用不了了，后来发现官方的cdn的确比较好用。
前提是pod版本1.8+，查看pod 版本，pod --version
pod repo remove master
或手动删除，目录是在 /用户/XXX/.cocoapods/repos/,此目录超级大，删除cocoapods目录即可。
pod install 可以看出从cdn安装类库。如果是新项目使用，需要pod setup再使用
