I'm using Windows 10, a Dell XPS 13, and v1.4.1 of Android Studio. I have SDK Tools 24.4.1 installed as well as Google USB Driver 11. # On the phone I have USB debugging enabled and can see the device in File Explorer (i.e. documents, pictures, etc.).
But the device never shows up using adb devices
, nor in Android Studio.
I've never had this much trouble getting an Android device debugging before, but I don't know if it's Marshmallow or the Nexus 6P that's to blame. More importantly, I've no idea what to do at this point to get it debugging.
I spent a lot of time with this problem. You need to manually download the driver here (http://developer.android.com/sdk/win-usb.html)
Then go to "Devices and Printers", right-click on "MTP", and choose properties.
Click "ADB interface", then click "Properties"
Go to "Driver" tab and update driver with the file you just downloaded. (Make sure you unzip them first)
