- Android Wear is a wearable platform designed for small, powerful devices, worn on the body. It is designed to deliver useful information when you need it most, intelligent answers to spoken questions, and tools to help reach fitness goals.
- Maximize your everyday tasks at work or play. Google smarts deliver your commute info, directions, timely reminders, and more. Just say "Ok Google" to ask any question and check off to-dos – right from your wrist Android Wear requires a phone running Android 4.3+ or iOS 8.2+
- Available for sale at the Google Store, Best Buy or Amazon
- Android Wear consists of a (open) Android OS and a (closed) Wear framework running on top of it, in charge of running the user interface, managing apps and communicating with the companion device (your phone). This framework is owned and managed by Google as closed-source. Google takes it very seriously to avoid fragmentation on this platform, and takes the ownership to maintain the Wear framework for ALL devices by themselves.
- There are three different Ambient modes in Android Wear. The first is the regular ambient mode where the display is dimmed but it still supports antialiased text. There’s the low-bit Ambient mode that limits the colors displayed. There’s also the burn-in protection mode that shifts the screen contents a few pixels so the same pixels aren’t being used over and over.
- Tell story of rejection on Google Play
- Navigate to ~/Library/Android/sdk/platform-tools (This is the default path on Mac OS) and type ./adb -d forward tcp:5601 tcp:5601 to establish a connection on port 5601
