Asus Nexus 7 not recognized by Android dev tools v

Question

Problem: Asus Nexus 7 not recognized by adb when correctly installed and connected

Setup: Asus Nexus 7 tablet Windows 7 64 bit OS

Steps taken:

1. Installed 64 bit Java JDK (http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html)
2. Installed Android SDK (http://developer.android.com/sdk/index.html)
3. Installed Google USB driver (http://developer.android.com/tools/extras/oem-usb.html)
4. Set tablet to USB debugging mode

In the Windows Device Manager, the Nexus is recognized as an Android Device via Android Composite ADB Interface. The device status indicates it is connected and working properly, running driver version 7.0.0.1 (8/27/12 update) from Google.

However, when I run adb devices at the command prompt (in the sdk/platform-tools directory), the Nexus does not come up as an attached device - the list is empty.

Does anyone have any insight on what the problem might be? I have tried uninstalling and reinstalling all drivers, restarting the computer each time. I have tried a variety of usb ports and cables, as well as switching between MTP and PTP connections with no success.

Answer 1

In my case when I got an empty list using "adb devices" I found that the device manager showed the Nexus 7 tablet under 'other devices' with that dreaded yellow exclamation point indicating that the driver was not installed correctly. Why Windows recognized part of the tablet file system, I don't know. In any case I manually updated the driver to the google usb driver in android-sdks\extras\google.

Then adb gave me the following:

C:\Users\Brian\android-sdks\platform-tools>adb devices

List of devices attached

015d25785b601611 device

instead of a blank. I hope this doesn't mess anything else up but I can now talk to the device.

Download universal windows adb driver(Koush). Worked for me for windows pc's. http://www.koushikdutta.com/post/universal-adb-driver

Answer 3

What worked for me is downloading the USB driver from the ASUS website:

http://support.asus.com/Download.aspx?SLanguage=en&m=Nexus+7&p=28&s=2

(you have to select the OS, which sometimes doesn't work, e.g. on the link Google returns when searching for "nexus 7 driver"). In that case, click on "Drivers and Download" and search for "Nexus 7". That gets me a page with a working OS selection.

Answer 4

Hey I found a solution to this via mkh at https://groups.google.com/forum/?fromgroups=#!topic/android-developers/0-RzE0v-G3k

Try this (as quoted from the above source)

When the Nexus 7 is plugged in there is a persistent notification that indicates "CONNECT AS / Media Device (MTP)". In this state adb devices will not show the Nexus. Not exactly obvious why, but I you select the second option "Camera (PTP)" the device is available for debugging. This choice is persistent, and I'm guessing that with a band new device it will connect as MTP until told otherwise

Answer 6

Install Google usb driver from SDK Manager. Later go to Device Manager, under "Other Devices" you'll see "Nexus" with the yellow exclamation mark. Right Click>Update Drivers>Let me choose>Let me pick from device drivers on my computer. Select android-sdk folder and click ok. This solved my problem
