Android Studio: No target device found: Why?

2019-08-05 12:37发布

When I first start Android Studio opening an existing project, and click Run, I get the error message Error running app, No target device found. I have my Samsung plugged in and ADB debugging enabled. It correctly shows up with the adb devices command and ADB shell works fine. I tried adb start-server with no joy. Strangely, If I start 'Debug app' first and then 'Run' it works fine, but I don't understand why this annoying step is necessary. Other StackOverflow answers said to do "Edit Configurations" but that doesn't show the options suggested. I'm running AS V3.01. Any clue?

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.

Go to Run->EditConfigurations->DeploymentTargetOptions and select Open Select Deployment Dialog. This will allow you to choose your usb device when you click run inside the Android Studio editor.
