I am developing Xamarin forms app. I am not able to deploy app in nexus 6p( phone is not listed in device list ). Tried below steps, still phone is not detected.
I have installed Google USB Driver using Android SDK manager.
I have downloaded usb driver for nexus 6p and done 'Update driver software'
option in device manager under 'Portable devices' section. Device
gets displayed as 'Nexus 6p' within Portable devices section in
device manager and also seen as local drive( next to C: drive ).
Selected droid project as startup project.
But phone is not listed in visual studio device list. Any help?
Make sure the 'USB DEBUGGING' option in DEVELOPER OPTIONS remains checked on your connected Android Device.
I've lost lots of time because this item would uncheck itself for some reason between reboots/restarts and Enabling/Disabling the DEVELOPER OPTIONS.
If anyone else is still struggling with this in 2017, and your USB debugging is definitely on and it's still not appearing - I managed to fix this by turning developer options OFF then ON again from the device's settings. Also ensure that the USB option is set to:
Charging - Just charge this phone
I couldn't get any other method other than this to work. The device was then immediately detected by Visual Studio 2017 for me.
You ABD interface is not installed on your system, so first install the ABD driver from your local machine using (C:\Program Files (x86)\Android\android-sdk\extras\google\usb_driver).
And check your device is in developer mode.
If all the setting will be good then your visual studio automatically detect your device and you can start to debug your app on your device.
If you have installed VS2017 in parallel to VS2015, you also may have a look here Android devices not showed anymore in VS2015 after installing VS2017

I am new to android development and am trying to run a test app on my android phone. But it will not detect my device when I click "run". I have tried to go through the OEM USB driver installation but it always says "Windows has determined that the best driver for this device is already installed. There may be better drivers on Windows Update or on the device manufacturer's website." When I unclick "Include subfolders" it says "The location you specified does not contain any driver package (.INF) files." I have tried other methods through device manager of installing OEM USB driver software, both selecting the directory C:\Users\My name\AppData\Local\Android\Sdk\extras\google\usb_driver and the one where I installed the samsung usb driver. I have been attempting to follow this link: https://developer.android.com/studio/run/oem-usb which is where android studio sent me.
Lets try the most obvious one. Have you enabled usb debugging on your phone yet? When I was starting android this has happened to me. If not enable it through your phone's Settings> Developer Options> Usb Debugging.
If the Developer options is not yet shown, tap the Build Number seven times to show it.
Build number is mostly found on About> Software Information.
You need to enable USB debugging in your device too, refer this link for process https://developer.android.com/studio/debug/dev-options
I am very new to Android development. I am trying to create and run an app from tutorial - https://developer.android.com/training/basics/firstapp/creating-project.html
But while running app it is showing me "No USB devices or running emulator detected" in Select deployment target dialog.
Background and what I tried:
I am using Lenovo K4 note Vibe.
Android version 5.1
I have enabled USB Debugging from my phone also checked "Enable OEM unlock"
I have selected USB "MTP" as connection mode when I connected my phone to machine.
I am using windows 7 and Android studio version 2.3.2
My device appears in "Device Manager" of my system i.e. It is installed properly.
When I connect my phone to my system it shows AutoPlay dialog, asking to run "Run Lenovo_suite.exe", I tried to see if my deice appears in Studio when I allow to run that app, but still no luck
I also tried by checking and unchecking "Enable ADB Integration" from Android studio, still no luck
I have already installed Android SDK for verion 5.1
I have also tried installing "Google USB driver".
I also tried connecting my device to all of my machine port
I am tried using Emulator, but it is really very slow on my machine, it takes around 2-3 hours just to boot. So, I am using my phone.
Your assistance in this matter is greatly appreciated
this problem just happen when your USB connection mode is not work in debug mode, Like:
File Transfer Or MIDI device
The Charging Only is Work in android 5 and above
GoodLuck
a addition to above answer i think if you try to debug it , you will get better result since android if had problem throw a error that says restart adb.exe ,
another thing whats your hardware config ?
and have you tried genymotion , i prefer it over android virtual device , working with a real device is better , but i prefer when to concentrate on monitor have device on it ;)
As per My experience many device not connect
So you need to try this Windows Software to detected your android phone
Install it on your windows system PDANET+
Thanks for your support guys. After 2 hours of struggle I found below:
When I connect my device to the machine, it shows me a AutoRun dialog to Run Lenovo_suite.exe(Which I mentioned in my question), but instead of auto running, I explored that newly created lenovo drive, which had 2-3 setup exe's(usb drivers and magicPlus), I installed both and restarted my machine. When I run MagicPlus software, it helped me to Authorize USB debugging with some kind of fingerprints. And now my device appeared in studio.
I've just installed VS2015 Community with Xamarin to develop some mobile apps. The problem is, I can't achieve debugging Android apps on any device. Android Device Monitor shows empty list. I tried connecting different phones, which I know are detected on my friend's PC. I can explore their files from windows explorer, from there computer sees them.
USB Debugging on the phone is turned on.
USB connection mode is set to camera, no change at all.
I have Google USB driver installed in Android SDK manager.
I tried adb kill-server, adb start-server. Nothing changed. adb devices
shows empty list.
This is device manager while Developers options are disabled on the phone.
And here with enabled Developers options
I also tried updateing driver to google usb driver, but windows said it's up to date.
You most likely did not grant access to the device. Try to go into the developer settings on the smartphone and revoke the USB debugging authorisation. Then connect the phone to the pc and and wait for a popup on the phone which you should accept. After accepting you should see your device with adb devices.
You can also try to set the connection mode to MTP (instead of the camera PTP).
Hope it helps!
Enable the device for development
Goto: Device > Settings > Developer Options > tick USB debugging
Sometimes just restarting Visual Studio might help
Try the this:
1 - Close Visual Studio
2 - connect your device
3 - Restart visual studio with the device already connected by usb (with the device options checked)
This just happened to me. And it seems setting the startup project to your Android project fixed it.
My understanding is that the Google USB Drivers from the Android SDK Manager only work for Google Nexus devices (at least according to https://developer.android.com/studio/run/win-usb.html); annoyingly enough, to use other kinds of devices you'll probably need to download vendor-specific drivers. For example, I definitely had to download Motorola's drivers to use my Droid for debugging purposes. Unfortunately, for whatever reason Windows wasn't able to automatically detect that that's what it needed to download, so I had to download them manually.
I had the same problem, using a Samsung Galaxy A5
Google Drivers Installed
Samsung Drivers Installed
Phone shows up in file explorer
Plugging the phone in while Visual Studio was opened resulted in a pop up asking for permission. After authorising, everything worked perfectly. I didn't have to go into the developer settings on the smartphone and revoke the USB debugging authorisation.
To preface, I had connected my phone (a blackberry which had Android and full Google Play Store access) via Android Studio before so I KNOW it's possible, but when I was trying to do it with Xamarin I was having issues, Visual Studio just wouldn't recognize my device.
Found the problem appears to be the USB cable I was using. When I standardly plug in the USB, blackberry gives me the option to just charge the phone, or to enable File Transferring. But the first cable I was using always just charged the phone and didn't give me options. I tried switching the usb cable and voila, I got the prompt, and I can see the device now in the Start Debugging dropdown. So it looks like there's charge-only usb cables as well as Data cables. Be sure you're using a Data cable else it won't be able to see your Device
I had the same issue after updating Visual Studio found that in recent versions is better if you open VS in administrator mode to properly work, this should fix the problem.
I had previously revoked debug auth on my phone, but my phone didn't prompt me to allow debugging on my PC when I connected it again. Ended-up restarting my LG V30 while connected to my PC and I was prompted to allow debugging.
After that, Visual Studio 2019 version 16.10.0 adds my phone to the device list.
Running on Windows 11. Visual Studio 2022. But, I don't think the versions are really relevant here - included for completeness.
Followed all instructions re enabling USB debugging from the device. Also, the USB Drivers for my Samsung device were successfully installed on the Windows machine.
I was running the Duet Display application as I had previously installed it for use with my iOS devices. This appears to have created a conflict when connecting the Android device, as the prompt related to Duet would appear but not the prompt to allow USB debugging from the computer along with the RSA thumbprint. Once I exited the Duet app from my system tray and reconnected the Android device I got the prompt and it immediately appeared in Visual Studio 2022.
Here's some things I check when having an issue with Android device not appearing:
Enable developer mode on the device from settings
Install (e.g. to windows) the manufacturer's* developer USB drivers for the device
Ensure the Minimum Android Version in the AndroidManifest.xml is lower or equal to your device
And as always, try a different lead and restart both PC and Device!!
*Manufacturer Android USB Development driver links I know of:
Sony | Samsung | Google/Nexus | Blackberry
I have just updated from VS2015 (14.0.25402.00 Update 3) to VS2017 (15.7.5).
Amongst other things, I had to migrate a .forms app from 2.3.x to 3.1.x...
As it (according to MS) now should be possible to install also the Xamarin integration software in parallel to older versions of VS, I first (for security reasons) wanted to leave my “old” .forms app under VS2015 and .forms 2.3x and start to update to .forms 3.x with VS2017.
First, everything looked good - I was able to open my “old” .forms 2.3.x project in VS2015 (what was not possible in the earlier migration from VS2013 to VS2015).
But, I was not able to bring my two dev mobiles (both Samsung Galaxy S7) to work under VS2015 again, although, they were showed to my dev-machine (windows explorer) correct.
After wasting about a full day (doing every suggested workaround, I found on the web), I gave up und started to migrate the .forms project under VS2017.
Under VS2017 both mobiles were showed immediately without any problems and I was able to debug to the device.
So.. it seems, as the installation of VS2017 (with Xamarin integration SW) has “destroyed” something in the VS2015 installation regarding the access to the mobile devices...
I wasn't getting the USB debugging prompt on the device to trust the PC it was connected to and it wasn't appearing in the drop down list of devices in Visual Studio or ADB. Tried many things but installing the USB driver for the device (in my case Sony Xperia XA1 from: https://developer.sony.com/develop/drivers/
After installing this device driver by right-clicking the ADB Interface device in Device Manager and choosing the downloaded driver it showed the prompt to allow the PC and now works fine. This was on Windows 8.1 . I don't remember having to do the same for my Windows 10 PC.
I tried all the options but the only way I got it working is to unplug the USB cable and connect it on a different USB port.
After downloading phone specific drivers and restarting computer / restarting visual studio etc etc. What fixed it for me was from developer options
Disable USB Debugging
Enable USB Debugging
This was on a Samsung Galaxy, looks like although it was saying USB debugging was enabled it was in fact not enabled until I retriggered it using the above method.
I want to attach the Android device to Windows 8.1 trough USB
instead of using the built in emulator.
How can I do this?
Note : The device can be connected trough USB (USB drivers are installed),
and its in devaloper mode.
You first need to enable Developer Mode:
Android 4.2 and higher
Starting in Android 4.2 and higher, the Developer options is hidden by default. To make it available, go to Settings > About phone, and tap the Build number item seven times to reveal the Developer Options tab:
Xamarin's doc: Set Up Device for Development
Then you need USB drivers for your phone if you already do not have them installed, check Sony's support site.
Once your device is connected to your machine via the USB cable, debugging is just like debugging via an emulator.
Start debugging your application by pressing Cmd-Enter in Xamarin Studio on OS X or F5 in Visual Studio. When you do so, you may be prompted to choose the device to debug with.
Xamarin's doc: Debug on Device
Check that your device is showing up for Android's adb:
1) Find where Visual Studio/Xamarin (or you) installed the Android SDK:
(Click 'Tools' in the toolbar at the top, then click 'Options')
2) Copy the the path for Android SDK Location
3) Paste that into your shell (cmd or powershell) proceeded by cd (we need to change to that directory.
4) CD into the platform-tools subdirectory
5) Run adb devices
This should display something like:
List of devices attached
XXX12345 device
If all that is returned:
List of devices attached
Then the device is not been recognized and will not be available for Xamarin (or any of the Google Android tools) to deploy.
Note: Also check to ensure that your phone is in Mass Storage mode, as some default to MTP mode and that will not work as an adb device
Note: If it’s NOT appearing in the list make sure that drivers are properly installed and you’ve enabled “USB Debugging" on the phone
You need to enable USB debugging in Developer Options in your phone, plug your phone and it should be detected by Visual Studio.
You may also need to download and install USB Drivers from Sony Drivers page
I'm developing an android app with Xamarin and Visual Studio 2013. I have connected my android applet to the computer. Sansung Kies recognizes the device. Adb recognizes it also because when I type "adb devices" the device appears in the list. But when I debug the app Visual Studio doesn't let me choose my device, it only proposes to me to use the android virtual emulator. In my device the "USB debug" option is enabled. So what am I doing wrong?
EDIT
Just got a new machine and ran into the same problem.
Following these steps:
http://visualgdb.com/KB/usbdebug-manual/
as suggested by Veverke in the comment below fixed the issue for me.
just had the same issue and fixed it with a combination of these two links. Obviously our issue isn't the exact same issue that's listed in the first link but that's why I had to use both to kind of synthesize a solution.
https://web.archive.org/web/20140410204811/http://krumelur.me/2014/01/30/xamarins-visual-studio-plugin-missing-android-devices-genymotion-and-parallels-desktop-dont-panic/
http://developer.android.com/tools/extras/oem-usb.html
Basically, in Visual Studio 2013 start the Android SDK Manager. Scroll all the way down to the 'Extras' folder, where you will find the 'Google USB Driver'. Mine was already installed, so I deleted the package, confirmed I wanted it deleted, then reinstalled it.
Then, I opened Windows Explorer and right clicked 'Computer', then clicked 'Manage' (need Admin priviledges). In the newly opened Computer Management window I clicked 'Device Manager' under Computer Management > System Tools in the hierarchy on the left.
In the main window, I expanded 'Other Devices' and saw the device I was looking for. I right-clicked it and chose 'Update Driver Software', then 'Browse my computer for driver software'.
Now you need to hit Browse... and find where you installed the packages.. for myself it was under
C:\Users\zumberge\AppData\Local\Android\android-sdk\extras\google\usb_driver.
Click next, the you need to choose to accept Google, Inc. as a trusted source.
Then the process should be finished and you'll be good to go.
Don't know if you need to restart VS2013, but I did for good measure.
Hope this helps and it's not too late.
For VS 2015, LG Nexus 4 and Windows 7, following solution works for me.
Debugging On and Off during the running instance of Visual Studio, your physical device appears in the device list.
Restart of Visual Studio 2013 has resolved the issue for me.
Details:
Visual Studio was open while I was trying to make the device visible to the system.
After installing the device driver, I have restarted the "adb" and saw that the device is added to the list "adb devices".
However the name of the device at the Visual Studio was not changed, some numbers.
After restarting the Visual Studio, real name of the device is shown "NVIDIA Shield Android TV.."
Then I did not get this error anymore.
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

After enabling debug mode on my android device, I found I had to change the 'USB PC Connection' option. It was set to 'Charge Device'. When I switched it to 'Media Sync (MTP)' and reconnected to my PC it then showed up in Device Manager, but the drivers did not appear to be working with VS. I reinstalled the 'Google USB Driver' in SDK Manager. I removed my device in Device Manager and added it back using the Google USB Driver. When I disconnected/reconnected the device to my PC, Windows asked what I'd like to do with the device. I realized the first time it had asked me, I quickly clicked 'Do Nothing'. This time I noticed the first option was to run an exe on the device to install the driver. After the install completed I disconnected/reconnected the device and the device prompted me to allow my PC to debug. After selecting 'Allow', the device showed up in VS while VS was already open.
Also make sure you have the correct configuration selected for your device. (eg. ARM for most smartphones)
If its set to one that your device doesn't support, then the device won't show up even if adb can see it. Simply switching the configuration solved the problem for me.
Try restarting adb server using:
select "Tools" from top bar then
select "Android". In the list there will be an option to restart adb server as "Restart Adb Server".
After clicking it everything works fine.
It worked for me.
I followed most of the steps mentioned, but still couldn't get it to work. Some things I did were:
download and install google driver from android sdk manager
locate the device in windows device manager and update driver (pointed to the google usb driver)
switch usb connection from mtp to ptp
restarted visual studio
restarted computer
Finally, what worked for me was googling the drivers for my particular android device (lg g4) and landing on this site . Once I installed the drivers I was immediately able to debug in visual studio using my device. it works whether the usb connection is mtp or ptp.

In case you are using Samsung and have MyKnox installed, you cannot enable USB-Debugging until you uninstall MyKnox as stated in This Link
