I'm trying to test an Android application and have a device connected via USB. The device detects (and charges off) the USB connection but I can't seem to find any record on the computer (running Windows 7) that the device is connected. I looked in Device Manager and did not see an "Android Devices" category, nor did I see an "Other Devices" category. I looked on the device manufacturer's website to see if they had drivers; I could not find any. Does anyone have any idea as to how I could get the device to show on the computer? Thanks!
Most probably windows and especially android adb will see your android device after installing the Google USB Driver
I had the same problem for many of my android devices and most of them are running fine with the driver from google. Only for some sony devices I had to install special drivers.
In Android Studio go to Tools -> Android -> Android Device Monitor. Once it opens close it, this will reset your adb and you should be able to see your device
Your problem sounds related with drivers
the Google USB Driver works only for some android models, some other drivers are installed as plug and play but some others you have to install manually.

Also sometimes it happened to me that the adb didn't recognize the device while the screen was locked so you could also check that out.
It turned out that the USB cable I was using was a charge-only cable. After switching the cable out, the device showed on ADB.

Android Studio is not recognizing any external emulators (phones) connected to it.
I have tried the following mentioned things without any success:
Installed the device driver. (It is working fine. The device recognizes my
phone.)
Turned on USB Debugging.
Kill-server and then start-server commands.
I am using Android Studio for Windows.
Probably you haven't installed the driver for your phone (if you use Windows). For instance, if you use Nexus or Pixel phones, you should install this. If you use Samsung phones, try this link.
It worked for me. If you still cannot see any of the devices, try calling 'Invalidate Caches / Restart' in the File menu in the Android Studio and restarting the system.
Hope it helps!
I had the same problem, my problem was I was using a cable that cam with the phone that acsually would not transfer any data from\to the phone, the moment I changed the cable it worked like magic.
Just try changing a cable 1st, the PC has to recognize the device even if You have no drivers, if Your phone doesnt ask You to give permission to access from PC than the cable is just a charging cable!
Hope it helps.
Set up a device for development (android documentation) :
On the device, open the Settings app, select Developer options, and
then enable USB debugging.
Set up your system to detect your device.
For Windows: Install a USB driver for Android Debug Bridge (adb). For an installation guide and links to OEM drivers, see the
Install OEM USB Drivers document.
When you connect a device running Android 4.2.2 (API level 17) or
higher to your computer, the system shows a dialog asking whether to
accept an RSA key that allows debugging through this computer. This
security mechanism protects user devices because it ensures that USB
debugging and other adb commands cannot be executed unless you're able
to unlock the device and acknowledge the dialog.
I have a Vodafone smart first 6 phone, that I want to debug over bluetooth. I have turned on usb debugging at developer options and also allowed mock locations. I downloaded the usb driver for it from http://androidxda.com/download-vodafone-usb-drivers . I have windows 8.1 and android studio 1.2.2
When I connect my phone to my computer the phone sais "USB debugging connected" but my android studio doesn't see it, altough my computer recognize it as a media device. The adb devices command isn't see it either.
All this steps worked for me for previous devices, I have debuged a lot of android devices before but I cannot find a solution for this vodafone phone. Can anyone help me?
Thank you!
Deleted the two 'vf695' entries in device manager, disconnected the phone, installed PDANet (http://pdanet.co/), selected the 'unknown device' option, followed the instructions, seemed to do the job.
I just found the solution after 1 week searching go to this blog and you will download all the zip file http://www.mediafire.com/download/5ff6s5bk1couva9/Compelte_USB_Drivers+PDanet+Adb_Installer.rar install first C++ then find Universal ADB DRiver it will get your ABD with ! mark restart you will find you are so so so so happy as I am now don't forget to configure your mobile with this configuration:
Setting - Storage - click in to three dots USB computer connection - then choose (MTP) Media Device\
We change your mobile device to developer mode click on USB debugging connected and choose USB debugging
Eclipse is not able to detect my android device even though it is connected to my computer. I had it working on my computer earlier, but my hard drive crashed so I had to reinstall/setup eclipse, and now it doesn't work. I have enabled USB debugging. I updated my USB drivers/ android devices. I tried connecting my android phone first, and then tried my tablet, but there was no change. I tried restarting the ADB server. The android project runs on the emulator, but the emulator takes so long to load and is laggy. I did a lot of research on how to fix this, but nothing is working. In my eclipse console it says, "Failed to find an AVD compatible with target 'Android 4.4W'."
if you have root, you can try to use Wireless adb via wi-fi. for this you must install from GooglePlay app like "wireless adb" run it and connect from cmd like this:
"e:\androidSDK\sdk\platform-tools\adb.exe connect 192.168.0.68:5555"
Also i recommend you to install free third-party android emulator BlueStacks, it work very fast! faster then real device connected by usb
For virtual device try Genymotion
For hardware
-first check if your device is connected - adb devices //some serial number should list. If empty, you need to install proper drivers manually.
also check in windows Device manager
Try to disable USB debugging then enabled USB debugging.
Relay! Yeah it's work.
For several weeks, I was able to connect my Nexus 7 2 to my computer running Windows 7, and Eclipse would recognize it, allowing me to run apps on it. The device also showed up when I ran the adb devices command. Every time I plugged the Nexus 7 into the computer, the tablet asked if I wanted to allow USB debugging at that time. (Oddly, it never asked me whether I wanted to always allow it from that computer, but I didn't care.)
I recently updated the tablet to Android 4.4.2. I also updated the Android SDKs through the Android SDK manager. Now, when I plug the tablet in, I do not get prompt about USB debugging on the tablet, and neither Eclipse nor adb can see that it is there.
Here is a list of things I tried to do, gathering ideas from various forums around the web.
Re-download the Asus drivers for the Nexus 7 and update the driver. However, Windows does not even recognize this as the right drivers for this device.
Turn USB Debugging off and on on the tablet, and also revoke all USB debugging permissions.
Change the connection mode from media device to camera
Switch the runtime from Dalvik to ART
Type adb kill-server followed by adb start-server in the command line
Delete eclipse and all the Android SDK and download them all over again
None of this worked. Any other ideas on what to try?
It turns out that the Nexus 7 definitely needs the Google USB Driver. Finding, downloading, and installing this driver worked perfectly.
Because Google's Android OEM drivers page does not include the Nexus 7 in its list of devices that need the Google USB driver, I had been trying the driver from Asus, which did not work. I did not try the Google USB driver because for some reason my SDK manager said it had downloaded the driver, but the driver was not to be found.
Finally I found I could download the Google USB driver from this page, which clarifies that all Google Nexus devices need this driver. Now I have successfully re-connected the tablet to ADB.
I submitted a documentation bug report to Google here in hopes that the OEM drivers page can be updated to reflect that all Google Nexus devices need the Google USB driver.
Nexus 7 tablet with Android 4.4.4. Settings > Storage > USB Computer Condition.
Two checkboxes: MTP and PTP. Uncheck both.
With your phone disconnected
In windows explorer - right click computer, go to manage, in computer management find and uinstall device driver (under Android device)
Download new drivers from http://developer.android.com/sdk/win-usb.html#top
Connect the phone, windows will try to install new drivers, install drivers manually with drivers downloaded as above
The above worked for me
For me, after updating to Android 4.4.2, it was critical that I connected the device as a Camera (PTP) rather than as a Media Device (MTP). Previously, before the update, I was able to connect as a Media Device (MTP).
The problem is that you have not all needed drivers (PC can recognise your phone like usb device but debugging would not work). I solved this problem in Android 4.4.4 by uncheking all items (MTP, PTP, UMS) from menu: storage->USB computer connections and than tick 'Media device(MTP). Now all works fine.
thank you Arthur, I found Nexus 7 tab not working even after unchecking or checking. Problem solved by unchecking USB Debugging (under developer options).. settings>Developer option> USB debugging. then check (put tick the MTP device):.storage->USB computer connections and than tick 'Media device(MTP)
Complete checklist:
Enable debugging onto the device
Select USB Connection as PTP (camera)
Install the driver from http://developer.android.com/sdk/win-usb.html
Before you try anything, make sure you update your Build related tools using your Android SDK Manager. Your adb might be outdated.
I'm trying to test an Android Application on my Galaxy Nexus (from Google). I use Windows 7 Home Premium 64 bit and Eclipse Java EE IDE for Web Developers.
My device doesn't show in Eclipse DDMS view. My device also doesn't show when I run adb devices in cmd.
I have USB debugging enabled.
When I try to install the USB driver as shown here I get a message that my device software is up to date.
I also tried killing the adb server and starting it again.
Give the Universal Naked Driver a try? Be sure to follow the steps in the forum post.
Nexus devices require the Google USB Drivers, you can get them through the SDK Manager.
If you have them installed and the device still is not detected try the following:
Use a different USB port (for me the USB 3.0 port is always making problems)
Restart the device and the computer
Restart ADB
Also take a look here, which explains how to install drivers for the Nexus S.
I had a similar problem. I could not get my device to show up in my Eclipse devices window. When I typed adb devices, no devices were discovered. Fortunately, I discovered this website. It basically had me install a generic driver for my Motorola (Android 2). It had other drivers for Samsung and other manufacturers. After the install, my Motorola phone became visible with ADB.
