Multidevice development
We're changing the way you create compelling, cross-device experiences. By delivering a core framework that enables devices across the Android ecosystem to multiply each other's value, we're making everything work better together.
Simplified cross-device interactions
We built a software stack that abstracts away underlying connectivity technologies so you no longer need to worry about the connectivity capabilities of users' devices.
Flexible developer toolkit
Mix and match the Android Cross device SDK with other Google solutions. Choose the tools you need to build compelling multidevice experiences.
Enhanced user experiences
Create exceptional user experiences by enabling seamless interactions between devices, including eliminating the friction of multidevice sign in.
Cross-platform development
Developers don't build just for Android, which is why we support development that extends beyond Android to include ChromeOS and other platforms.
Multidevice use cases
