it is crucial to helping you make the right product and marketing decisions. This is especially important when you're deciding your advertising strategy and budget. "> Posted by Neto Marin, Developer Advocate Understanding how people find your app and what they do once they've installed it is crucial to helping you make the right product and marketing decisions. This is especially important when you're deciding your advertising strategy and budget. Today many app measurement companies and ad networks offer ad attribution solutions based on referral data. As such accurate install referral data is vital for correctly attributing app installs, as well as discounting fraudulent attempts for install credit. To help you obtain more accurate and reliable data about your installs, we're introducing the Google Play Install Referrer API , a reliable way to securely retrieve install referral content. Using this API, your app will get precise information straight from the P...

Posted by Wojtek Kalicinski, Android Developer Advocate, Akshay Kannan, Product Manager for Android Authentication, and Felipe Leme, Software Engineer on Android Frameworks Starting in Oreo, Autofill makes it easy for users to provide credit cards, logins, addresses, and other information to apps. Forms in your apps can now be filled automatically, and your users no longer have to remember complicated passwords or type the same bits of information more than once. Users can choose from multiple Autofill services (similar to keyboards today). By default, we include Autofill with Google, but users can also select any third party Autofill app of their choice. Users can manage this from Settings->System->Languages>Advanced->Autofill service. What's available today Today, Autofill with Google supports filing credit cards, addresses, logins, names, and phone numbers. When logging in or creating an account for the first time, Autofill also allows users to save the new credentia...

Posted by Xiaowen Xin, Android Security Team The new Google Pixel 2 ships with a dedicated hardware security module designed to be robust against physical attacks. This hardware module performs lockscreen passcode verification and protects your lock screen better than software alone. To learn more about the new protections, let's first review the role of the lock screen. Enabling a lock screen protects your data, not just against casual thieves, but also against sophisticated attacks. Many Android devices, including all Pixel phones, use your lockscreen passcode to derive the key that is then used to encrypt your data. Before you unlock your phone for the first time after a reboot, an attacker cannot recover the key (and hence your data) without knowing your passcode first. To protect against brute-force guessing your passcode, devices running Android 7.0+ verify your attempts in a secure environment that limits how often you can repeatedly guess. Only when the secure environment...

Posted by Oscar Rodriguez, Partner Developer Advocate [ Note: This blog was amended in March 2018 to include our latest recommendations regarding app integrity verification, and in May 2019 to amend the quota increase request form link.] The SafetyNet Attestation API helps you assess the security and compatibility of the Android environments in which your apps run. Since it was introduced in March 2015, many developers have successfully integrated it into their Android apps to make more informed decisions based on the integrity and compatibility of the devices running their apps. Throughout the years, the SafetyNet Attestation API has evolved, and its adoption has steadily increased. However, as with any security/anti-abuse related API, there are many common pitfalls that may lead developers into developing unstable systems, or worse, into a false sense of security. In this post, we provide a list of the most common mistakes we have seen developers make when integrating the SafetyNe...

Posted by Marc Stogaitis and Tajinder Gadh, Software Engineers Driving is an essential part of our daily activities. So at Google we spend a lot of time thinking how we can make Android devices better and safer for our users. How we can prevent distracted driving and together build an open ecosystem to enable safety first smartphone experiences. Recently we launched Driving Do-Not-Disturb on the newly announced Pixel 2 generation of devices. Once enabled, Driving Do-Not-Disturb automatically puts your device into a do not disturb mode while driving. During this mode any incoming messages and notifications are silenced while you can still receive incoming calls, navigation directions and voice interactions using a connected Car bluetooth. The product is designed to limit distractions during driving while at the same time not getting in the way so users can continue to use navigation or other similar apps with minimal friction. Behind the scenes, it uses AI powered on-device Activity R...

Posted by Lukas Bergstrom, Product Manager, Android Developer Frameworks Team Android runs on billions of devices, from high-end phones to airplane seatbacks. The Android OS manages resources aggressively to perform well on this huge range of devices, and sometimes that can make building robust apps complicated. To make it easier, we launched a preview of Architecture Components at Google I/O to provide guidance on app architecture, with libraries for common tasks like lifecycle management and data persistence. Together, these foundational components make it possible to write modular apps with less boilerplate code, so developers can focus on innovating instead of reinventing the wheel - and we hope to keep building on this foundation in the future. Today we're happy to announce that the Room and Lifecycle href="http://developer.android.com/arch">Architecture Components libraries have reached 1.0 stable. These APIs are ready for production apps and libraries, and ar...
