Google today previewed Android "M," the next major version of its mobile operating system featuring Android Pay for mobile payments, app permissions, an improved web experience with Chrome Custom Tabs, app linking, Doze power management, USB-C support, direct sharing, simplified volume controls and a handful of other incremental improvements and bug fixes.
Google also announced free unlimited high-quality photo (16MP) and video (1080p) photo storage through a new service aptly named Google Photos for iOS, Android and the web, contextual information and a new "Now on Tap" feature for Google Now, and an "Internet of Things" operating system and HomeKit rival called "Project Brillo" for devices like thermostats and lightbulbs.

Android M delivers an improved web experience with Chrome Custom Tabs, which function as a Chrome web view overlaid in third-party apps with prefetched content. Google partnered with Pinterest, for example, to integrate Chrome Custom Tabs, providing all of Chrome's benefits such as signing in, saved passwords, autofill and multi-process security. Chrome Custom Tabs are available on the Chrome developer channel today and in Q3 for the public.
Doze is a new power and charging management system built into Android M that tracks your device sync activity and exponentially blocks background app activity when possible for up to double the amount of standby battery life, based on a side-by-side test of a Nexus 9 running Android Lollipop and Android "M" Developer Preview.
Google also briefly announced several other features of Android M, including USB-C support, simplified volume controls, improved Bluetooth low energy scanning, support for seven additional languages, unified Google and device settings, direct sharing and more. Android M is available today as a developer preview for the Nexus 5, Nexus 6, Nexus 9 and Nexus Player and in Q3 for the public.
Android Pay

Android users can add their supported credit and debit cards to the Android Pay app and easily tap to pay at over 700,000 retailers and businesses that accept contactless payments, such as American Eagle, Bloomingdale's, McDonald's, Macy's, Staples, Target and Walgreens. Android Pay can also be used for in-app purchases in supported apps.
Google announced that four major credit card companies in American Express, MasterCard, Visa and Discover will support Android Pay, alongside major financial institutions and AT&T, Verizon and T-Mobile in the United States. More partners should be added in the future.
Project Brillo
Brillo is a slimmed-down version of Android that's designed to power the Internet of things. It's an operating system that will be made available to manufacturers, who can build it into devices like thermostats and lightbulbs. It includes support for Wi-Fi and Bluetooth 4.0.

Google Now
Google announced a new feature for Google Now in Android M: Now on Tap. With Now on Tap, you can tap on the home button of an Android device to get more information about what's on the screen.

Another example: On stage, a chat window with a discussion about laundry and a restaurant was brought up. A tap on the home button brought up a to-do card and cards for Maps, Yelp, and OpenTable.
Google Photos
Google announced a new Photos app centered around three ideas: a "home" for all your photos, deep organization, and sharing. Google Photos includes unlimited high-quality photo (16MP) and video (1080p) storage at no cost. It's launching today on Android, iOS, and web.

Google Photos includes auto-organization that organizes photos by people and place. Its facial recognition capabilities are impressive, able to recognize a person even as that person ages. A Photos Assistant feature automatically creates GIFs and videos from your content, which you can share or delete. Sharing is simple -- you can group multiple photos and instantly get a link that lets other people see the images.
