ADB No Devices Found

Question

I am attempting to install an Android app on my brand new Nexus 10  I have a  apk file  I have downloaded the Android SDK  installed  Android SDK Tools    Android SDK Platform-tools   and Google USB Driver  I have checked the setting on my Nexus 10 for  Unknown Sources    When I run  adb devices  from the command terminal  it doesn t list any devices  I attempted to follow this recommendation  because it was identical to a suggestion I had previously found here on Stack Overflow  After following those steps   adb devices  still returns an empty list and to make it worse  when I connect my Nexus 10 to my PC  Windows doesn t show any folders within the device   I have undone the steps in that link  along with everything else I have done so far  as well as uninstalling my Nexus 10 from Device Manager and reinstalling it  but I am still not seeing any folders in the device   Is there anything I am missing to get my device to show up in ADB devices   What can I do to get Windows to see the folders within the device

Edit  I recommend you DO NOT run ADB under VirtualBox if you are using a Windows Host  Somehow I got VirtualBox to lock the device drivers on the host  eventually making it so that the ADB wouldn t work on the client nor the host for any device I plugged in  To fix  I removed VirtualBox extensions on the host and ran http   www nirsoft net utils usb devices view html to delete the incorrect drivers  I could not get the correct drivers to load while VirtualBox extensions were installed  and this problem was a complete bastard to diagnose and fix   Edit 2  Also the following is probably out of date  now that Google have released an integrated ADB extension for Chrome   What an installation nightmare    Here are the steps I needed to get my Nexus 10 recognised on an XP virtual machine running under VirtualBox    If you get asked to install Nexus 10 drivers  make sure to untick  don t ask again   you WANT to be asked again    Plug in the Nexus 10 USB connection Turn on debugging in the Nexus 10 settings Developer menu  tap  About Tablet  7 times to get that menu   In your virtual machine settings  host   add the samsung Nexus 10 device to the USB Device Filters  important - selecting it from the devices menu didn t seem to work   In guest install java jre  if you don t have java installed   In Control Panel  change Java settings so that java doesn t run in the browser  to help prevent security issues   In guest get the adk zip file and put it somewhere permanent  I needed to delete the  android config directory from the user directory because I moved the directory   Run the SDK Manager exe - if it doesn t work  try running sdk tools android bat which seems to give better error reporting  From SDK Manager install the Google USB driver package  Unplug the Nexus 10 and plug it in again  and install the Google USB driver package  Restart the guest  running c        sdk platformtools  adb devices finally shows me the device

If you have enabled Developer Options and USB Debugging for a Nexus  the win-usb supposedly works   One tell-tale sign whether your driver is right is if it s got ADB in the name in Device Manager   For my Galaxy line  I had a driver installed  but it wasn t the ADB driver   For many non-Nexus Androids  the win-usb driver will not work  Instead  you will need to install one of the OEM drivers  https   developer android com studio run oem-usb html  This finally got me an ADB compatible driver  and after switching to PTP adb finally was able to find my device

For my Nexus 6P downloading drivers from Google helped resolved the issue  Here is the URL with documentation  And here you can download the driver itself   P S  I saw some people advice to download some drivers from random places on internet  While this might help it s too dangerous in my mind to download unknown drivers from unofficial places  So the one from Google worked well for me

For the Blu Studio 5 5s ADB drivers  you have to go through this hoop   I am certain it is the same with all Blu phones or maybe for all non-Google mfg phones  I am not sure     First of all if you connect the Blu device with USB cable and USB Debuggin off  you will see that Windows 7 loads a generic driver for you to copy on off files to the phone and SD storage    This will appear when the USB cable is first plugged in and appears as a device icon under Control Panel  Device Manager  Portable Devices  BLU STUDIO 5 5 S  or the device you are working with     Do not bother getting the hardware ID yet - just observe that this happens  which indicates you are good so far and don t have a bad cable or something       Go to the phone and switch on USB Debugging in the Developer section of your phone    Notice that an additional item appears as an undefined device now in the device manager list  it will have the yellow exclamation mark and it may have the same name of the phone listed as you saw under Portable Devices   Ignore this item for the moment    Now  without doing anything to the phone  it should be already in USB debug mode  go back to the Portable Devices in Device Manager and right-click the BLU STUDIO 5 5 S or whatever phone you are working with that is listed there without the exclamation mark  listed under Portable Devices    Right click on the icon under Portable Devices  in this example the name that appears is BLU STUDIO 5 5 S   On that icon select Properties  Details  and under the pull down  select Hardware IDs and copy down what you see   For BLU STUDIO 5 5 S I get   USB VID 0BB4 amp PID 0C02 amp REV 0216 amp MI 00 USB VID 0BB4 amp PID 0C02 amp MI 00    Note if you do this out of turn  the HW ID will be different with the phone USB debugging turned off   You want to copy the value that it changes to when the USB debugging is ON   Now do as the instructions say above  of course customizing the lines you add the the INF file with those relating to your own phone  not the Nexus 10    Here is what to customize  when you downloaded the SDK you should have a file structure expanded from the ZIP such as this    adt-bundle-windows-x86 64-20140321 sdk extras google usb driver   Find the file named  android winusb inf in the usb driver folder Make a copy of it and name it anything  such as myname inf Edit the myname inf and add the lines as instructed above only modified for your particular phone    For example  for the BLU STUDIO 5 5 S  I added the following 2 lines as instructed in the 2 locations as instructed       BLU STUDIO 5 5 S  SingleAdbInterface           USB Install  USB VID 0BB4 amp PID 0C02 amp REV 0216 amp MI 00  CompositeAdbInterface        USB Install  USB VID 0BB4 amp PID 0C02 amp MI 00   Note that you add these lines to both the 32 and 64 bit sections  matching how the example in the tutorial reads   Now go back up to the unknown device that appeared in Device Manager when you switched on device USB  debugging and right click on this item  has yellow exclamation mark   right click on it and then select Update Driver Software  and then Browse My Computer  Let Me Pick  click on the Have Disk button and browse to find the myname inf    Continue to agree to all the prompts warning you it might not be the right driver    As the final step  Windows should have identified the device as Android ADB Interface and once that is done  you should be able to go back  open your CMD window and run the command  adb devices  as instructed in this tutorial and now you should see that the phone is now discovered and communicating      Now you can go have fun with the adb command

There s obviously a ton of different problems that could be causing this  and a ton of different solutions to go along with those problems   So think about all the solutions   If you ve gotten this phone and computer pair to work together before  but they aren t working any more  it might be a specific program on your computer rather than a problem on your phone  Some programs install use their own adb  and only one of these can connect to your phone at a time  I think this makes a race condition  so sometimes it ll connect fine   Some programs that run adb   HTC Sync Manager - uninstall this   chrome   inspect - lets you view localhost on your phone  Just close the window when you re done with it

If you re at all familiar with Linux use that instead of Windows   On a Raspberry Pi  do   apt-get install android-tools-adb andoid-tools-fastboot   There are no special USB drivers needed  it just works   Android is based on Linux so you re working more in native mode   Many of the problems I see here are Windows problems   osx may have advantages over Windows here too   Adb and fastboot both have man  manual  pages which are accessible from Linux   Original question  I see no devices in adb when the phone s in fastboot mode  adb and fastboot seem to be mutually exclusive  you can only use one or the other at a time   USB debugging has to be on

Sometimes ADB loses connection to the device  and needs to be reset   If you have everything else working  ie USB driver installed  Developer settings enabled on the device   and still can t see your device  you need to reset the ADB process   This is available in the DDMS Perspective  from within Eclipse   Devices tab  the triangle on the far right includes a menu item to perform the reset    Otherwise from the command line  you can reset it with the following 2 commands   adb kill-server   then  adb start-server
