Google has ported Android Things to the Raspberry Pi. Differences to regular Android are
- support for I2C , PWM and other interfaces
- no Android-style multitasking , a single headed or headless foreground app
- no staus bar , no menu , no home screen , no notifications
- no Play Store + infrastructure (currently deployment is over adb only !)
- less focus on Multimedia (video/3D acceleration is still unstable)
The target is not people looking for a cheap Android box. It is for developers and OEMs which want to create
medium-to-high powered IoT (Internet of Things) devices.
