Android Studio: No target device found: Why?

Question

When I first start Android Studio opening an existing project, and click Run, I get the error message Error running app, No target device fou

Answer 1

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.
