The title pretty much says it all: I'm working on an Android Studio (3.5.2) project on my Windows 7 64-bit running laptop, I connect my Samsung J7 (2016) to the laptop through the original Samsung cable but Android Studio simply can't see the device. If I try to do the same on my desktop computer (same Android Studio version but on a Windows 10 64-bit OS) everything works just fine.
Here comes the funny thing: the "adb devices" command shows the device (and I'm 100% sure it's my smartphone since it's the only device connected). The Android Studio toolbar keeps showing "No devices" anyway.
I've spent 3 hours on this and couldn't find a solution. I already tried every suggested solution around the web (stackoverflow.com included), but I achieved nothing:
Disabling/Enabling USB Debug function in the Developer Settings of my smartphone (including revoking USB debugging authorizations)
Running Android Studio as admin (sometimes it solves strange stuff...)
Trying to USB connect through PdaNet+
Android Studio built-in troubleshooting service (re-scanning for devices actually makes me see my smartphone but it's treating it as if it can't be used as a debugging device; anyway the smartphone-computer connection is just fine: I can browse my files and all. Killing and restarting the ADB server does nothing)
Tried connecting both as PTP and MTP
Tried both the Google USB Drivers and the Windows Update drivers (those the computer gets when you first connect the device)
Thanks in advance :)
if you use linux as your PC OS. may be try to install adb will help you..
apt-get install adb
that's work for me.
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.
Eclipse DDMS Not recognising my Nexus (samsung)phone .I had install usb drivers externally as well as from device manager. also had conneceted device by usb cable in debug mode still it is not able to recognise in DDMS.please help what to do .Thanks In Advance.
I had a similar problem with another phone using Win7 x64. You should check first if all drivers are installed correctly.
Control Panel -> Device Management and check if there's something wrong.
If you use Win7 x64 try to reboot your system and start Window without using Driver signature.
Hope this help you
Install Usb drivers from this site
Samsung Galaxy Nexus usb Drivers
also it gives all samsung phone usb drivers.
1)Go to this site
2)Go to the manuals and downloads
3)download exe for drivers
4) install it
5)then connect your device.automatically it installs drivers for apropriate device .
Drivers got installed successfully and still device is not recognized by DDMS? Here is what worked for me. https://stackoverflow.com/a/32519507/1567675
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.
I have tried installing the Samsung Captivate Drivers, but ADB does not see them. I have got the google adb drivers in sdk directory but everytime i try to install this driver it says that Windows think I have the best driver for the device. It keeps the MTB driver. I have tried uninstalling but MTB driver keeps coming back. I am trying to get the debug bridge to work to a Samsung Captivate. adb devices shows nothing.
try to use Samsung Kies. It has samsung drivers with in.
you can find it here :

works fine for me with the Samsung i5700 on Win7 x64
Installing Samsung New PC Studio worked for my Samsung Fascinate. You get a bit more than just drivers, but it worked.
It is just a matter of installing the Samsung Captivate Drivers. (Some people have to reinstall them several times) and then just making sure that USB is definitely set for debugging. This should work. The Android application itself needs also to be enabled for debugging android:debuggable="true" in the Android-Manifest. This is what it needs. Note this is how to get ADB working so that if you type adb devices you will see the Samsung device. Kies is an option for file sharing.
