title: My Android Studio doesn't recognize my device
body: <p>I'm learning How to develop App Android. I'm using Android Studio. I created a "HelloAndroid" as my first project, but I'd like that running in my Smartphone, but it doesnt't work. When I click in Run app, it open a window for choose a device, but nothing appear. I guess that it doesn't recognized my device. However, I enable developer mode in my cell phone. May anybody help me, please? I already tried all.</p>
  
  <p>My Windows is 8.1 64-bit
  Android Studio 1.3.2</p>
