The first issue is Google Assistant and Google Family. The positioning of Google Assistant is more important than Google Now. It can realize two-way dialogue, a bit like Microsoft's Xiaona Xiaobing. The whole process is a dialogue, rather than the traditional question and answer mode, and Google Assistant can give real-time personalized feedback based on user's use scenarios, locations and questions.

Google Home can provide music, entertainment, news and other information through the Internet of Things and smart furniture at home through dialogue, and supports third parties. Third party partners are welcome to develop together.

Then Google released the smart information application Allo and the new video application Duo. Allo, based on the user's mobile number, supports Google Assistant expansion, has a secure encryption method, ensures the user's privacy, increases the expression library, and can adjust the expression by sliding sideways. The more intelligent chat conversation makes the user's communication more interesting. What's more, Allo supports quick response to images, which can help users better fulfill their needs by combining image analysis content with Google Assistant. Allo supports encrypted chat, but in stealth mode, it provides end-to-end encryption and chat expiration burning functions.

Duo is a phone number based video calling software with security encryption, and supports Android and iOS platforms.

The highlight of Android N has been released, and Vulkan's modern 3D graphics API has been added, which can enable games to run at a higher frame rate, with a 30% to 600% increase in running speed. The application installation speed is increased by 75%, and the code is reduced by 50%. The new JIT compiler not only improves the performance, but also speeds up the installation and download speed. In addition, Android N supports the addition of the latest 7 background applications to the multi task screen, and finally integrates the one click cleaning button. Of course, Android N also supports split screen multitasking and picture in picture functions. The Android N system in Android TV has also appeared. Later today, the beta version of Android N will be released, supporting Nexus 6P, Nexus 5X, Nexus 6, Nexus Player, Nexus 9, Nexus Pixel C and others.

Android N integrates VR functions, and some existing devices can already support Android N's VR mobile standard. Its built-in VR mode optimizes the performance and delay, with the delay as low as 20ms. At the same time, Google has released the Daystream VR device, which is equipped with a remote control and has the somatosensory function, allowing users to better experience VR. The Daystream device was released this fall. Finally, Google will also build a Daystream app store to support VR. Daystream also integrates Google Play movies, Google Street View and photos. The latest Android N Developer Preview has supported the Daystream API, and now developers can develop new applications.

The release of Android Wear 2.0 has brought better dials. Users can more easily master their own information, contacts and health through customization. In terms of input mode, intelligent reply, better handwriting recognition and small keyboard have been added. The new Google Fit API can bring about automatic activity identification and automatic music playing without the need to connect with mobile phones. Android Wear 2.0 is more independent and can access the network directly. Later today, the preview version of Android Wear 2.0 will be available for download, and the official version will be released this fall.

At the end of the meeting, Google provided developers with the latest Android Studio 2.2, which supports 10x fast and instant running, and the simulator speed is three times that of the previous one. Android Studio 2.2 has newly added layout design and APK analyzer to facilitate viewing the application size and the reason for the memory occupied, enhance JIT compiler, support Java 8, and enhance C++support, including CMake and NDK Build. Android Studio 2.2 preview is available for download today.

Also released is the next generation mobile analysis tool Firebase, which is adapted to Android and iOS systems for free and unlimited use. The simple SDK, Android iOS、 Both web pages can be used.

In addition, Google has released a new project: instant applications. Through instant applications, applications do not need to be installed completely, but only part of them can be installed to run. In addition, instant applications load specific parts that need to run for application fragmentation. Once the necessary parts are installed, the rest can be installed with one click. Instant applications also support Android Pay. NFC can be used for quick payment in two simple steps. Instant apps will be launched later this year.

Finally, Sundar came to the stage to summarize the first day of today's Google I/O conference, including machine learning and artificial intelligence. Sundar especially introduced AlphaGo and talked about the application of deep machine learning in the early medical detection of diabetic retinopathy, which is a very difficult type of diabetes.
