Google Pixel not found in Android Studio

Having trouble with Android Studio connecting to my Pixel phone. I'm sort of out of ideas and am looking for suggestions. I feel like I'm missing an obvious step.
Things I've done:
Made sure developer options is on with USB debugging on.
Have tried switching from MTP to PTP.
My computer recognizes the Pixel just fine under windows 8.
Made sure android studio is up to date including "Google USB Driver" installed under SDK tools.
My previous phone (Droid mini) connects just fine.
Tried different USB ports for the cable to my phone.

Encountered this problem today as I tested on other people's phones. I found 4 possibilities why a device may not be recognized:
Case #1: The USB cable supports charging but not data transfer.
Case #2: Developer options haven't been enabled on target phone (see: https://www.verizonwireless.com/support/knowledge-base-215055/)
Case#3: Developer options enabled, but USB debugging hasn't been enabled. Go to Settings > System > Developer Options > USB Debugging
Case #4: Some (but not all) phones require MTP transfer mode to be enabled. It can be enabled by sliding a finger from the top of the screen and tapping "Android system - USB charging this device" > Tap for more options > Transfer files.
Hope this helps someone ^_^
EDIT:
It's come to my attention that there's another possibility. I don't know what causes this, but if you get really stuck, sometimes you need to go into Settings > Developer Options > Debugging > Revoke USB debugging authorisations. This will reset your device USB pairing fingerprint which will often bring the phone back as a device target in Android Studio.

In Pixel devices USB debugging is enable when:
Step 1. Enable Developer Options to double tap on Build Number, you can get it by search with build in setting.
Step 2. Enable USB debugging Option, to enable this just to search usb debugging in settings.
Step 3. Pixel devices require USB tethering mode to be enabled, It can be enabled by sliding a finger from the top of the screen and tapping "Android system - USB use for " > Tap on USB tethering.
After completion of all these steps you will be able to use you pixel device as enabled for debugging in SDK.

Android Studio / SDK Manager will provide the driver but Windows might not automatically install it for your device. Try checking the device manager, unplugging and reconnecting the device or let the device manager search for new hardware.
The driver (when installed via SDK Manager) will be found by windows when provided with the SDK root directory, usually AppData/Local/Android/sdk

I have had the same trouble with my Google Pixel 2 (Android 9); I couldn't connect it to ADB in Android Studio 3.3. In my special case, AS runs on Kubuntu 18.04 in a VMware Workstation on a Windows host.
I have to do following steps every time I want to connect the phone (the phone is already in developer mode):
Plug phone via USB into the computer (and connect it to the VMware guest, if you use it)
Phone: Swipe down the notification bar, there should be a message 'Charging the device via UDB'
Tab on it and change the 'Use USB for' from 'No data transfer' to 'File trasfer'
You can activate 'USB debugging' on your phone's developer screen before or after this procedure, both works for me.

That happened to me with a generic Type C to USB Cable (White Cable in the Picture Attached). Then I bought another Cable (The Black one in the Picture Attached) and it worked perfectly. It was the Cable. Make sure to have one that says "Data & Power".
Hope it helps!

The solution to device not found when running adb devices from windows 7 standard terminal for my Pixel 4a 5g was to simply update my google USB drivers. https://developer.android.com/studio/run/win-usb

If dev options aren't available, double click the build number until a notification appears stating dev options have been enabled.

Android Studio - No USB devices detected

I tried to play Android Studio 2.0 with my mobile without success, what I did are:
In my mobile, Apps/gear icon/Settings/SYSTEM/{} Developer options/ Android debugging/, enable the Android Debug Bridge(adb) interface (set tick).
After plug in my mobile to my PC with a USB cable, I found A0001 in my Computer folder. Within A0001, I can see the files in my mobile.
In my PC, run Android Studio/bin/studio.exe, "Select Deployment Target" window shows with message "No USB devices or running emulators detected"
I have tried two different USB drivers but got no lucky.
Perhaps I should tell Android Studio where is my USB driver? But, how?
Can you help?

I had the same problem too and I managed to resolve it this way.
First, enable debugger mode in your android device.
Go to Device Manager from Start Menu and try to find ADB Interface with an error symbol on it. This generally happens because windows sometimes fail to load all the mobile device drives.
Next, Go to http://adbdriver.com/downloads/ and download the driver installer, unzip and run it.
Now go to Android Studio and you should find that everything is working fine.
Chill....

same here... but I hope you can avoid this problem the same way I Did.
There is an "universal ADB Driver for all Android Devices".
Yep... sounds like magic.
Just follow this link.
https://devs-lab.com/usb-adb-drivers-for-all-android-devices.html
Fun fact there is no "Step 5" in that article so I'll give you.
you have to enable "USB Depuration" from "Developer Options" connect your cellphone to computer as a "MTP storage" , after windows detected your cellphone as a "Portable Device" Execute ADBDriverInstaller.exe (that downloaded from devs-lab)
check the device list and your cellphone will say "Driver incorrectly", select your cellphone and press install.
Step 6: Once the process is completed, you’ll see something like the image that appears there (in the link).
I hope that somebody else work this

Go to Run > Edit Configurations...
Under Deployment Target Options select Show Device Chooser
Dialog from the drop-down-list
See picture for reference

After struggling with this problem for a while, I found that there are certain cables that can only charge your phone, and even though they seem to be working, they do not allow your phone to be used as a "Media Device" and therefore Android Studio does not detect it.

Go to
Tools | Android | Enable ADB Integration
Make sure it's enabled. When I upgraded to 2.X it was for some reason disabled for me and it took me hours to find it.

I just cannot beleive why it is so difficult! let me try again and please check my steps again:
I installed Android Studio 2.0, then run Computer/OS(C:)/....../Android Studio/bin/studio.exe.
The Android Studio window appeared in my working area Computer/OS2(J:)/Users/MyAccount/Desktop/.
I connected my mobile with my computer, Cpmputer/A0001/ appeared, from it, I can see the files in my mobile.
I clicked the run icon in the Android Studio window, a "Select Deployment Target" window apeared with message "No USB devices or running emulators detected".
(I got two USB ports and tried both but got the same result.)

Finally found the solution : )
1. Install device’s required driver. (for me it was motorola device
manager)
2. Download Google Usb Driver from SDK Manager
3. Open your phone's setting->developer options and turn on USB debugging.
4. connect your device to computer
5. Go to Device Manager from Start Menu and try to find if there is ADB Interface with an error symbol on it.
5.1. If yes, then right click on the ADB interface->Update driver
software->Browse my computer for driver software-> Let me pick from
a list of device drivers on my computer->Select Motorola ADB interface
5.2. Now one confirmation will pop up in your mobile, accept it
5.3. Now you should see no error mark beside the ADB interface in your
device manager

There are 3 steps to set up your phone for debugging:
1) Change your phone to developer's mode by going to Settings, About Phone, Software Info, Android Version - tap at least 7 times on the Build Number text. You will get a message saying you are now a Developer.
2) Enable USB Debugging in Settings - Developer Options. Make sure you are not connected to your USB port to see the USB Debugging option enabled, otherwise it will be disabled.
After you plug in your USB, swipe at the top of your screen, you will see USB Debugging on.
3) Make sure USB connection is set to Photo Transfer (or MTP - Transfer photos and videos). After you plug in your USB, swipe at the top of your screen, and you will see Tap to change USB options on the menu. Tap it, and select Photo Transfer option.

Perhaps your mobile manufacturer does not provide the proper driver.
Go to Device MAnager and look for: Android Composite ADB Interface. If it's there, the driver is properly installed. If not... You and I are on the same "wagon"...
I tell you: Acer? Never again.

USB debugging somehow got turned off under developer options on my Samsung. Turned it back on and it worked, but only by clicking on "debug app" instead of on "run app".

With me, when connecting the mobile to the pc, three options appeared on my mobile.
Charge this phone
Transfer Files
Transfer Images
I thought I should select "Transfer Files", but it dd not work
But it only when works I choose "Charge this phone"

Few ways to resolve this problem.
Case 1: Install PdaNet+ in your system. (worked for me).
Case 2: Enable the USB debugging option in your mobile. Setting > developer > Check "USB Debugging".
Case 3: Change from MTP to PTP.(sometimes vise versa works).

Question is Your development sdk no mobile version android sdk Platform.
For example, my android phone system is 6.0, i need download sdk Platform 6.0.

First, try to revoke the usb sessions in the developer options, then try downloading an oem usb driver
If then doesn’t help you can try opening the device manager on windows, right click on your phone, select uninstall. This worked for me if I had the same issue.

I couldn't find my android phone or any USB device I connect to my windows laptop on the hidden icons. Well, my mouse and phone could charge but I can't seem to see my phone in the File Explorer option.
I prefer running Apps using my phone rather than emulator in Android Studio and yet I couldn't see my phone when I connect using the USB.
This helped me solve all my problems after several hours of searching for solution.
Download Universal ADB Drivers - One size fits all Windows Drivers for Android Debug Bridge
Please use this link: https://adb.clockworkmod.com/
I hope this works for you like magic!
I can see all the devices I connect using the USB cable and my mouse receiver.

LG G3 device not recognized by Eclipse on Windows

I recently bought LG G3 and I have enabled debugging mode but Eclipse is still not recognizing it, back when I used the Galaxy S3 for development I had to install Samsung Kies. The G3 drivers are installed and I can see it in My Computer, do I need something like the Kies but for the LG? If so can someone please post a link for that?

See update below
I found the answer that worked for me.
When you plug in the phone, bring down the status shade, pick the USB item ("USB connected") then, from there, pick "Internet connection" -- I chose Ethernet, but I'm not sure the choice matters on the dialog that pops up..
This enables USB debugging to become active; leaving it on Charging, MTP, or PTP does not work.
Once you do this, you can follow #Siddharth's steps to setting the ADB drivers, if needed. (You may need to use the actual LG drivers and not the Google drivers, but once I got this far, it was just like any other phone.)
Caveat
For me, even after going through this once, I still get the "installer" first and then have got go in and choose the "Internet connection" again. But, at least it works.
Update 10 Dec 2014
A recent firmware update has, indeed, removed the "Internet connection" as an option. Instead, PTP now works. I still get the "Connected as an installer" notification every time I plug in the phone and have to click on the notification then click on "Camera (PTP)" -- or wait about a minute. It's slightly better than what It was.
Also note: When this change occurred I had to install the drivers again for the phone, since it comes up as a different type of device when "Camera (PTP)" is chosen than when I used the "Internet connection" option.

For me, this has solved the problem: simply go to LG's website, http://www.lg.com/us/support/software-manuals, select the model (I have selected 'D850') and go to Software Updates tab where you can download the driver. I have installed it and then Eclipse recognized my device. I'm working on Windows 8.1, by the way.

After a lot of searching and trying all solutions still I couldn't connect my LG G3 to eclipse on mac. Finally I find this solution, it works for me hope for you works too:
Install LG USB driver for mac
Go and enable developer mode in your G3 (Setting->About phone (in General Tab)--> Software information --> Tap 8 times on Build Number) then you will see the message which says the Developer option is enabled
In this step you expect that after connecting your mobile via USB cable, the Eclipse detect it
But for me it didn't happen
in this step you need to go (Setting--> Developer Options--> and turn off this option from above green (on/off) switch then again switch on this option from same place (If you don't do this step the "USB Debugging" mode will stay fray and you can not enable it)
In Developer Options menu scroll down until find the "USB Debugging" then tic it and enable it.
almost finished , you should back and configure running mode for your application and see the G3 in your connected usb devices

Try this solution :
Right click on My Computer --> Properties --> Device Manager
Right Click on your device --> Update driver software
Click on "Browse my computer for driver software"
Give path of your android sdk like "D:\Android_Sdk\sdk\extras\google\usb_driver" and tick "Include subfolders"
Click
Now repeat the steps till "Browse my computer for driver software".
Then click on "Let me pick form list of device drivers on my computer". Click on the first option and click next and then click yes. Drivers will be installed for your device.
Hope this helps.

Change the USB mode to PTP and you will get the RSA prompt.
Within the prompt, select allow it > ok and you are done.
This worked for me when I had the same problem on a Mac computer.

To contribute to possible solutions for this fix: I am using an LG G3 on a Mac.
In my case, ADB saw it as a device when I checked, and the Mac showed the device information in the System Information window, yet Eclipse did not see it. I also did not get the RSA confirmation pop-up when I connected the device through USB.
To fix, with my G3 connected, I selected the USB PC Connection (either from the navigation bar or through the settings) and changed it to be Send Images (PTP). Once this was on, I was given the RSA pop up and Eclipse recognized the phone in the Run Configurations window.

If you have this problem on Ubuntu; here is what I did to get it working:
Switch to PTP from MTP on the phone (this assumes you're connected via USB)
Disconnect the USB cable
Go to settings -> developer options and select revoke usb authorizations then ok
Make sure USB Debugging is checked
Reconnect the USB cable and your phone will say its connected as an installer; wait a minute or three and debugging mode should appear on the status bar (on the phone)
Open Eclipse and go to DDMS
Select "reset adb" in the dropdown if your phone isn't appearing yet

Working on Windows 7. All of the solutions from other sites didn't help (i.e. restarting adb and switching between MTP, PTP, Charing). In the end, I found this article (http://www.technobuzz.net/install-lg-g3-lg-drivers-windows-mac-usb-adb/), which contains links for the necessary drivers for the lg g3 (and some others I think). This did the trick and made the RSA key fingerprint dialog appear finally. After confirming, adb and eclipse recognize my device perfectly!

I had this buggy error with my LG Optimus L3 phone connecting to Win7/8 machines!
Cause: Device Driver was missing as it seemed at the end when I fixed it!
How to Fix:
Search through web (using Google) "LG < Your_Phone_Model Number > Drivers Download".(Ex.:- Go to About phone in your settings list > Model Number, for me it's LG-E400f)
Mostly the first few links are related to the required Device Driver download page.(Ex.:- for me I got the following link and for each device driver LG or most of the other vendors/manufactures have that kind of a Manuals and Drivers Page) Visit that page mentiioning about software update and drivers downloads.
Scroll down to the section of "Manuals and Software Update" and doing just the Step 1 was enough for me, which is "Install the USB DRIVERS "
Download it(for Mac or Windows) > Install It > Check Your Eclipse ADT > and it should be visible under Devices tab by now
Cheers!!!
Hope this helps to someone else to clearly get to the solution!

it seems that Eclipse shows the offline mode for lg G3 and some newer devices
and there is no way no use these devices for ADB debugging
there is a way
I am using windows 10
1- download this 11 MB file < http://dl2.uncox.com/android/upload/platform-tools-v22.zip>
2- then go to the directory that you installed the SDK
3- extract the zip file in to the platform-tools folder , override all files(click yes to all) be sure that Eclipse doesn't running
4- open Eclipse and select your android device that stands in devices tab at the right-top corner of your screen and then you can see the arrow near the screen- capture icon and you will find the reset-ADB. click on it ,after that your phone will ask you to allow android debugging for your device click on it
5- congratulations .now you can see that your device shown online
i hope this will help .sorry for my english

I also had a great deal of trouble when attempting to debug android applications on my shiny new LG G3. What ended up working for me was first installing the default google drivers onto the G3 and then following the process detailed by #lilbyrdie.
The process of installing the google usb drivers is very nicely gone through here.
However, with the most recently pushed android update to the G3 there are no longer the options for internet connection or charge only; but they seem to have fixed this defect forcing you to make this odd choice to enable debugging. The only options remaining are MTP and PTP, but if you pull down the notification drawer, choose the 'USB connected' notification (assuming the device is connected to your computer via USB of course) and from there click on 'Media sync (MTP)' even if it is already selected then debugging should be enabled.

Android can't update on the fly the developer mode. So, after turning on developer mode (and given you have the latest driver) switch the green button(under settings->general->developer options) to off and then back on. Then turn debug mode on (after that windows recognizes a new device) and you should be good to go.

In my solution for Windows 7 was helpful to update Android SDK Tools to latest version.

ADB Single/Composite values for LG G3 phones -
I found it was necessary to update (~userName/.android/)adb_usb.ini file with the line 0x1004:
# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x2207
0x1004
In addition, I needed to add the following entry in (.../sdk/extras/google/usb_driver/)android_winusb.inf:
;
; Android WinUsb driver installation.
;
...
[Google.NTx86]
...
;LGE Android Phone
%SingleAdbInterface% = USB_Install, USB\VID_1004&PID_633E
%CompositeAdbInterface% = USB_Install, USB\VID_1004&PID_631D&MI_00
%CompositeAdbInterface% = USB_Install, USB\VID_1004&PID_631D&MI_01
[Google.NTamd64]
...
Oh, and set USB to PTP as well as turn-on USB debugging.
When you're all done with the file modifications and several passes at installing the drivers (ref. earlier posts), you can verify your phone is ready via the Device Manager. It will list your phone as "Android Device"->"Android Composite ADB Interface". I believe an earlier post explains setting up the drivers

Cant connect Sony Xperia L C2104 to eclipse

I have Sony Xperia L (C2104) and I want to connect it to Eclipse (Juno) for testing and debugging Android Apps. I have installed the Sony's PC companion software. I have turned on the USB Debugging via 'Developer Options' and the USB Connection Mode is MTP.
When I plug my device to Laptop, running Windows 8, the notification bar shows 'USB Debugging Connected' and 'Internal Storage & SD Card Connected'. However, when I start Eclipse, It does not show my device in 'Android Device Chooser' window..
I think the device drivers should have got installed along with the PC Companion Software but When I right click on My Computer -> Manage -> Devices, It shows a device 'Android' in Other Devices category along with a '!' with it. So maybe the drivers are absent.
Please help, need to test app on it urgently. I Searched drivers for Xperia L on Sony's website http://developer.sonymobile.com/downloads/ but couldn't find the driver.

This works for me . I changed the following setting in the phone.
Settings > Xperia > USB Connectivity > USB connection mode
and select Mass storage mode (MSC).
By default Media transfer mode (MTP) is selected and USB cable must be unplugged to change this option.

I know this is an old thread still I am adding few details from Sony official website there is a read me provided. It says If you can’t find the driver you are looking for, drivers for all Sony smartphones and tablets are available in our PC Companion software.
So for making this work you need to download PC companion software form this link. After installing the software you will be able to download the driver for your phone.

You need an adb driver, not just their standard driver (sometimes they are the same, but often they are not).
For a list of adb drivers, follow this link ADB driver listing
Here's a Sony specific list

At times for sony experia the developer options are hidden. To unlock it do the following.
You have to go to settings-> About Phone -> build version.
Click on build version 7 times to unlock the developer options. I tried this and it worked perfectly.
Hope it helps.

It's late to answer this question, but I had the same problem just now and solved it
Install the universal ADB driver from http://adbdriver.com/upload/AdbDriverInstaller.exe
(you might have to change between Media Transfer mode and Mass storage mode on your phone, they use different driver)
On eclipse, Open Perspective > ddms
There's a devices panel that opens up. There's a small white triangle on the right, click on it and click reset adb

I had the same problem. Worked for me installing PdaNet driver downloaded from http://www.junefabrics.com/android/download.php

I downloaded Sony PC Companion from Sony's website and installed it. That came with appropriate drivers..

I did the same trick that Akash has posted
"At times for sony experia the developer options are hidden. To unlock it do the following.
You have to go to settings-> About Phone -> build version.
Click on build version 7 times to unlock the developer options. I tried this and it worked perfectly.
Hope it helps."
It also worked for my sony Xperia L C2104

android sdk eclipse, samsung galaxy tab 2, How to recognize devices

I'm trying to develop on Samsung Galaxy Tab 2 with eclipse and android sdk. I've already installed Samsung Kies and turned on USB debugging on my device.
It looks like eclipse didn't know the new samsung driver. Did I forget something? What should be the windows pilot of the device? I think is the samsung pilot. Should I be able to create virtual samsung at this step? What is the correct url for the samsung add on site?
I'm on windows 8. I'm using Eclipse Juno and adt-bundle-windows-x86_64-20130219

I suggest you try this.
Unplug your device. Install this drivers. After installation plug it in again.
It should recognize your device.
Link : http://www.samsung.com/us/support/owners/product/SCH-I705MKAVZW

If Windows recognises the USB mass storage on your device, what you can do, is go to Device Manager, Right-click on My Computer > Manage > Device Manager, find your device, should say not recognised or something like that, click Update driver software then click Browse my computer for driver software then click Let me pick from a list of device drivers on my computer, you should end up with a list, click Show all devices or something like that. Then search for your manufacturer in the list, in your case Samsung, click on manufacturer and find Android USB debug or something like that (it's a certificate) then install that.
Restart your adb in Eclipse, to do so, go to devices tab, (to get to it, click Window > Show view and find Devices if not in that list, then check in Other list at the bottom. Click on arrow in image below, and select restart adb . Finally restart Eclipse.
Hope this helps.

I suggest you to run cmd, then go to platform-tools root, and run the following command:
adb devices
This will list all attached devices and tell you if your samsung phone is recognized by Android Debug Bridge, if it is not then search for another driver for your phone and try again.

On a Galaxy Tab 3 7.0 you need to go to Settings -> Developer Options (scroll right down the list to the left), enable it in the top-right switch, then turn USB Debugging on.
Running adb devices will then show your device if you have the Samsung Mobile USB Composite Devices driver installed (through Kies or otherwise).
