I am using Android Studio 1.1.0 under Windows 8.1 Pro and trying to connect my Nexus 7 running Android version 5.1.

I am following both Lynda tutorial and looking at android developers tutorials but was not able to find what's wrong.

The device is visible in the Device Manager:

enter image description here

The Google USB driver has been installed:

I have enabled a lot of Developer options of my Nexus 7 including:

  • USB debugging
  • Stay awake
  • Bug report shortcut

I am not seeing the details when I try either to run or debug the application. The device is not listed here (as shown in the video):

enter image description here

I have try to:

  • add android:debuggable="true" in AndroidManifest.xml
  • restart the PC
  • reconnect the device

I was not able to find Unknown sources option in the Developer options which was recommended in some other answers of this issue.

Could you advice what to try?

  • Disabling and re-enabling USB debugging solves my problem 98% of the time, have you tried that? – IntegralOfTan Apr 16 '15 at 20:10
  • @IntegralOfTan Thanks, I've try it (enable/disable it several times) but still nothing. – gotqn Apr 16 '15 at 20:17
  • Can you manually detect it with ADB? – Jared Burrows Apr 17 '15 at 17:50
  • @JaredBurrows Sorry, could you give me a link or more details of what you want me to check? – gotqn Apr 17 '15 at 17:54
  • @gotqn ADB - Android Debug Bridge. Adb is located in your Android SDK folder. http://developer.android.com/tools/help/adb.html – Jared Burrows Apr 17 '15 at 17:56
  • @JaredBurrows Check the edit of the question. Did you want me to do this? – gotqn Apr 17 '15 at 18:04
  • Click in the device manager listing to see the USB VID & PID which may have changed. On Windows you could be stuck having to use a universal driver or edit inf files; on OSX and to a degree Linux this is much simpler. – Chris Stratton Apr 17 '15 at 18:07
  • @ChrisStratton This is getting too complex for beginner like me. I even don't know why I have started to install the android stuff on windows. I have dual boot (`Windows 8.1` and `Ubuntu`), so I am going to give a try to the Linux. – gotqn Apr 17 '15 at 18:12
  • On linux, you need to follow the instructions for udev rules, and make sure you have one for the USB VID & PID which you can get with 'lsusb' - and that if you use their current proposal for the rule, you change the default owner username to yours. – Chris Stratton Apr 17 '15 at 18:14
  • @gotqn Yes. Using ADB is what Android Studio is going to use to connect to your phone. Can you run `adb devices`? – Jared Burrows Apr 17 '15 at 19:33

Click Revoke USB debugging authorization in Developer option and try it again.

Go to Settings -> Usb Connectivity -> Usb connection mode -> Check MTP mode.

And try sudo adb devices.

I suggest re-installing your ADB Drive in the Android SDK file and making sure your device is in Debugging mode.

I have decided to change my OS and install Ubuntu 15.04 instead. After I installed the Android Studio what I needed to do was to simply connect my Nexus 7 with my computer - the studio detected it immediately - no additional drivers and settings were needed at all.

Go to developer settings and change USB-mode to Charging. Solution for Android M.
