i have enabled usb debugging on my Nexus 7 (2013 model). But when i run adb devices command, the only devices listed are the running AVD emulators. Also i get no RSA fingerprint confirmation on my tablet.
I have properly installed the latest android sdk, and google usb drivers with it. Also in device manager i do not get any 'ADB Interface' option or such. The only place nexus 7 is listed is under 'Other Devices'.
When i plug the device in my friend's laptop everything works just fine, i get the RSA confirmation and everything. So the problem must be in my laptop. I thought it could be bluestacks so i uninstalled it, and also deleted every occurrence of it from the registry. Nothing has changed.
I finally solved this. The problem was with my Google USB Drivers. I tried deleting the package from SDK Manager and reinstalling it. But it didn't work.
So, I downloaded the drivers separately from here then replaced the existing files (\Android\android-sdk\extras\google\usb_driver). I got the RSA fingerprint message on my device.
