I know this type of question has been asked before but I couldn't solve my problem with any of the solutions.
My device is not being recognized by my emulator and the the in adb devices List.
I have enabled USB debugging in my phone and tried setting USB devices as my default device in edit configurations but the problem still persists.
I am using windows 8.1 and it doesn't work no matter which android device i connect.
Any help will be highly appreciated.
I have experienced this before. Here is what I have done (for Windows 10 OS). I am not sure whether you have tried this solution before.
Go https://developer.android.com/studio/run/oem-usb and download the OEM driver of your android device
Go to Windows Device Manager. For my case, I found a device, namely "adb" with a warning sign. (something like the following picture)
Click your device -> Driver -> Update Driver -> Browse my computer for driver software. Choose the OEM driver that you have downloaded in (1).
After the update, you should be able to see the device on Android Studio
i'll suggest you to check ur device driver or u can use this link universal ADB driver
& check with the minimal ADB & fast boot, device is recognizing or not.get ADB fastboot from this link
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
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 am trying to debug my application using a real device instead on the emulator. When I try to connect, it gives me the message:
USB device not found
I tried to unplug and plug it again, but it did not work. And I have also enabled USB debugging and unknown sources options in my device.
Any help is appreciated!
Thanks!
I had this problem with a Nexus 7 - it appeared in Device Manager fine but wasn't recognised by Android Studio. The device had USB debugging turned on. Eventually I noticed an icon in the top left hand corner that said "Connected as a media device. Touch for other USB options." When I selected this I was able to change from Media Device (MTP) to Camera (PTP) and then it started working.
If you are on windows, many times it will not recognize the device fully and because of driver issues, the device won't show up.
go to settings
control panel
hardware and sound
device manager
And look for any devices showing an error.
Many androids will show as an unknown USB device.
Select that device and try to update the drivers for it.
This solution works for every unrecognized android device... mostly general brands don´t come with usb debugging drivers...
go to settings
control panel
hardware and sound
device manager
And look for any devices showing an error. Many androids will show as
an unknown USB device or just Android
First thing you need will be your device IDs. You can get them opening up the device manager and finding the "Unknown Device" with a yellow exclamation point. Right click on it and select 'Properties', and then go to the 'Details' tab. Under the 'Property' drop down menu, select hardware IDs. There should be two strings:
USB\VID_2207&PID_0011&REV_0222&MI_01
USB\VID_2207&PID_0011&MI_01
Copy those strings somewhere and then navigate to where you downloaded the Google USB driver. Then you need to open up the file 'android_winusb.inf' in a text editor. I would recommend using Notepad++.
First, create a sub-section for your device. I called mine ';RCA 6378W2' but it doesn't really matter what you call it. Then, under the sub-section you created paste the Device ID strings you copied from the Device Manager, preceded by '%SingleAdbInterface%'. If you need help, look at this screenshot.
NOTE:
If you are using Windows 8 or 8.1, you will need to disable device driver signature checks before you'll be able to install the modified driver. Here's a quick video on how to disable device driver checks http://www.youtube.com/watch?v=NM1MN8QZhnk. Ignore the part at the beginning about 64 bit, your computer architecture doesn't matter.
Please look at this article, for more information and MacOS instructions.
Try a different cable, ideally an official Samsung one.
I had tried a crappy USB cable I had lying around and then tried another which was Samsung and works perfectly now.
Not sure why they would be different though but worked for me.
Found out for Samsung, Installing Kies also update the usb driver which solve my problem with connecting my Samsung Galaxy S Advance with Android 4.1.2 to Android Studio on Windows 7 64bit.
In this case the devise manager shows device driver is updated and working, but when I connect my phone Android Studio does not recognize my device.
I had the same problem with connecting my Galaxy Nexus to win7 x64. I solved it by getting drivers, they can be downloaded from here or also via Android SDK manager.
After you put your phone on developer mode, restart it. That worked for me, maybe it will work for you also. After restarting it, the phone was recognized, drivers were automatically installed. Note - I'm running on Windows 7.
I've been having this issue on Mac OSX Mavericks using Android Studio, using my Samsung Galaxy Express , I did a little trick, Run -> Edit Configurations - > Run -> Show chooser dialog. When I "play" and the dialog appeared, I connected my device and it did appear. ;)
You need to install the driver first. Follow the instructions on the Android's developers website:
http://developer.android.com/tools/extras/oem-usb.html
I had the same problem with a Samsung galaxy note 2. It was recognized on one pc but not on another one (both running windows 7 64b). After hours of struggling, I installed Kies (from the Samsung website) on the pc where Android Studio was unable to detect the smartphone (Kies was installed on the other one).
Like magic, Android Studio detected the phone !!! I noticed that the Kies installer installed some driver for the phone.
Consequently, for those meeting the same detection problem, I would strongly advise to first install Kies.
Galaxy S7, I had to go to Settings, Developer Options and allow USB Debugging. This asked to approve computer it was attached to and it showed up instantly.
I had tried restart the device, and it's work, popup and ask want to trust the mac for debug mode.
I am using Samung S8, I tried to install:
Intel Android Driver
Samsung USB driver
But the adb bridge driver was still missing.
I finally got it to work by installing the Samsung Smart Switch application which is a media manager application.
Updated at 2018-04-20: If you are struggle with the driver, just use http://adbdriver.com/downloads/
If you're using a USB Type-C cable, check if it has the charging and data transfer capability. Many USB Type-C cables are for charging only, and are not recognized by Android Studio.
Check installed drivers. If drivers ok, check device usb-port it could be damaged.
I have a Samsung Galaxy S4. Although visible from Devices, my phone was not listed as connected from Android Studio. I tried a few things independently, and then together, and found that only a combination of steps fixed the issue, so this is for you if measures listed above or on another site did not work on their own.
Enable USB debugging from "Developer Options"
Download Kies from Samsung. I believe Samsung US has replaced Kies with a new software called Smart Switch, but this did not resolve anything for me. I found a Samsung UK download of Kies that worked fine.
After connecting your phone to your PC via USB, go to your phone notifications and click on USB settings at the top. Switch it to Camera mode.
I repeat, only all 3 of these together fixed the issue, so if some fixes you have tried haven't worked, use these 3 and it could fix the problem for you. Best of luck.
Restart Android Studio Worked in my case
For me, this simple trick worked:
I actually enabled and disabled the listed USB Adapter for android in the device manager (Control Panel -> Hardware & Sound -> Device Manager). And holy moly it's working! :D
The solution for me was following the instructions at https://developer.android.com/studio/run/oem-usb.html#InstallingDriver. Specifically, the key part from that link that helped me to find the solution was this: "Install a USB Driver. First, find the appropriate driver for your device from the OEM drivers table below." This means that you cannot find a single link that applies to everyone as the solution. It will depend on your device! "So I visited the page to get OEM Drivers at https://developer.android.com/studio/run/oem-usb.html#Drivers. In my case, the device I was using was an LG K8 LTE. I had to go to http://www.lg.com/us/support/software-firmware-drivers#, Browse by product and I found the driver I needed under the Model Number "LGAS375 KG K8 ACG - AS375", Cell Phone Product. From http://www.lg.com/us/support-mobile/lg-LGAS375 I used the "Install the USB DRIVER" for Windows (http://tool.lime.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425).
Depending on the device model you are using, you will need to find the specific drivers that work for your phone, and that should work.
How to get connection to device working using adb command line:
USB debugging enabled on phone and phone connected.
I am exercising these commands on linux(redhat and ubuntu) but same commands work under the hood on windows. The device manager runs adb commands. You can find a console in your device manager or regular command-line works if you set up your paths to SDK.
If you can run adb and see something like ???????? in devices list ..
$ android-studio/sdk/platform-tools/adb devices
List of devices attached
???????????? no permissions
You might be running the adb server as a regular user.
You might have to run the adb server as root.
So kill the server as regular user and start it as root.
$ adb kill-server
$ which adb
$ sudo <fullpath>/android-studio/sdk/platform-tools/adb start-server
Now look at adb devices list, if it is first time this machine connects to this phone you will see "unauthorized".
$ adb devices
List of devices attached
MWS0216A31xxxxxx unauthorized
At this point on phone you should have dialog popped up and you can tap ok to authorize. Then you should see "device" in the devices list and commands like shell/push/pull/sync/backup... should work.
$ adb devices
List of devices attached
MWS0216A31xxxxxx device
$ adb shell "uname -a; df; ls /storage/sdcard0/Download"

Lovely jubly. Hopefully.
For example:
My file path:
C:\...\sdk\extras\google\usb_driver\android_winusb.inf
My data to paste:
;Tablet PC
%SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_0003&MI_01
%CompositeADBInterface% = USB_Install, USB\VID_18D1&PID_0003&REV_0230&MI_01
Well, in my case updating drivers, restarting Android Studio, restarting my phone, changing the USB mode or unplugging USB did not help.
Then I went to the dev settings in my phone, toggled the Dev. Mode off and back on, and it worked. AS was open and phone was plugged at the moment.
I had this problem occurring suddenly in Dell Ubuntu linux machine with Android Developer Studio. I did the following steps
1. I opened "System Settings"
2. Select the listed item "Software and Updates"
3. Click on the tab "Additional Drivers"
4. There was a mention about "Dell Inc: Unknown" and the option "Do not use use the device" selected. I selected the alternate driver mentioned and did an "Apply the Changes".
It started working.
I just ran adb command prompt and hit 'adb devices' and it showed daemon was not running. It installed itself and now i can able to see android devices there.
C:\...\...\source\repos\ABC\ABC\Ex.Android>adb devices
List of devices attached
* daemon not running; starting now at tcp:5037
* daemon started successfully
ZF22Q3T unauthorized
and Reload the project
Windows, many times it will not recognize the device fully and because of driver issues, the device won't show up.
1).go to settings
2).control panel
3).hardware and sound
4).device manager
Restarted my PC and worked in my case.
I'm running Windows 7, trying to connect my Android phone by USB so I can start developing in Eclipse. The phone is a Huawei Prism running Android version 2.3.6, and I've set it to USB debug mode. The phone's driver failed to install and I got the following error message:
Device driver software was not successfully installed
Android Adapter No driver found
I Googled around but couldn't find anything on this error. The Device Manager shows a yellow exclamation point.
I'm not sure if this is a device usage question or a development question. My goal is to get my phone to be available under Run As... in Eclipse.
Download and install Hi Suite. It's used for syncing Huawei devices, it'll have the driver you need.
http://www.huaweidevice.com/resource/mini/201105239635/hi_suite_en/
You must always install your specific phone USB Driver before being able to debug by USB.
So generally a " USB driver" search on Google does work.
I did it for you and found this page : http://www.huaweidevice.com/worldwide/downloadCenter.do?method=toDownloadFile&flay=software&softid=Mzk1MzA=
Is it the driver you tried ?
A more flexible way is to install the Adb Driver Installer: http://adbdriver.com/downloads/
Once you download it, enable USB debugging on your phone and plug it to your computer. Then, use the Adb Driver Installer to install the required driver. It works for any Android device! Hope this was helpful. :)
I recently found the right way to address this USB issue with Huawei.
Go to http://consumer.huawei.com/en/?method=toDownloadFile&flay=software&softid=Mzk1MzA=
Search: USB Driver
It will be the option HUAWEI Android Phones USB Driver
Make sure it is version v1[1].0 and file size 7.76 MB
Download zip, extract, proceed with usb download
Note: Make sure you debug and keep "stay awake" on before hooking up your device.
