• Enable USB debugging mode on Device How to enable USB debugging in Android?

• Select your device in tool bar and click on play button(Run application).

Answer 2

I found my problem. Under Run->EditConfigurations->DeploymentTargetOptions, I selected USB Device (my phone is a USB device, right?). But noooo, when I select Open Select Deployment Target Dialog, everything is peachy. Also, checking Use same device for future launches bypasses the dialog entirely and all is good.
