Wearable app development

A

AC Question

Hi folks,
I am developing android wearable app in simulator using android studio. In USB debugging I am using Sony Xperia SP in Windows 8 system.
ADB is not detecting my phone after executing the command 'adb.exe devices' in command prompt, but it detects emulator.
What may be the issue, wither its windows 8 compatibility with xperia(Android 4.3).
