I am a budding developer. I want to develop an app for Sony Smart Glass and I have bought the glass already started the process of developing with Android Studio. My question is how can I install the app in Sony Smart Glass? I have tried to read the Sony website but it's not mentioned there.
If it has USB debugging somewhere in the settings, then enable it. Then you would be able to run the app from studio or adb via usb cable. Or just push your .apk into that device and install it even with some file explorer. Even Bluetooth might be an option here if the device supports it.
This SDK is probably necessary.
If it has no port through which you could push your .apk to that device and it relies only on google play or its specific store (something like samsung used to have), then the only option is to use the store - but it shouldn't be that much restricted.
