When developing Glassware, you have two API options that you can use separately or together. Make the right choice based on your needs.
Use the GDK if you need...
Real-time User Interaction
Access to Hardware
Use the Mirror API if you need...
Or, use both.
Mirror API Glassware can invoke GDK Glassware through a menu item. You can use this hybrid model to leverage existing web properties that can launch fuller experiences that run on Glass.
