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 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 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 activated Developer Options" and checked "USB debugging". Google usb driver on sdk is already installed.
But still Android studio doesn't recognize my mobile (one plus two).
Means it is not shown in "Choose Device" window when I try to run my application
I tested my mobile on ubuntu and it works.
I am using windows 10
But it doesn't recognize one plus two
I tried following Android Studio Doesn't recognize my device- one plus one
but it did not help me.
Do you have any suggestion?
When you connect your OnePlus 2 to your Windows 10 machine, try changing the USB PC Connection settings on your phone. It may sound odd but selecting to connect as Camera (PTP) worked for me (although I don't have a OP2).
When you insert your usb, does your android phone notify you that it's connected via usb connection?
On Android Studio(2.2.3), the device somehow is not detected for me. The following worked for me.
Go to Tools
Click on Android
Disable ADB Integration
And Re-Enable ADB Integration
PS: However before updating Android Studio, never observed this issue, even with the same set of USB Drivers.
I am using the following tutorial to remote debug web pages on android chrome browser.

When I connect my mobile device on Windows 7 via USB cable and then navigate to,
chrome://inspect/#devices
No device is shown
do you have android ADB in your system? if not install it.
if you have ADB, then in command prompt run adb devices and make sure that your device is listed. if its not listed u have to install the device dirver. Also enable usb debugging on your device.
I know this is an older question, but I thought I would post my resolution - I had to enable Developer mode on my Galaxy Note tablet.
Open Settings, then go to About Device (where you see Kernel, Android-version etc) then tap your Build number 7 times.
Then check USB debugging under the now displayed Developer options menu item.
I know this is an older question, but I thought I would also post my solution:
Update your Chrome on your phone and on your PC.
Even if it says you have the latest driver for your device inside Device Manager, you may need an alternative. I went here and got the latest for my Samsung: Latest USB Drivers
I am trying to test an Android application through the Eclipse plugin on a real device. It is a Samsung Infuse 4G. I believe I have followed all steps on the Android page for testing on devices.
First of all, I cannot figure out what the Android OS version is because it does not show up in the settings. I can see that the firmware version is 2.2.1, so I assume I am running that version of Android OS as well.
Next, when I connect the device to my computer (running Vista, 64 bit), I get prompted with three options: Kies (firmware update), Media player, and Mass storage. When I look on the Internet, I see that I am supposed to select "Charge only", but this does not appear in the options with which I am prompted. I have already set USB Debugging to true through Settings > Applications > Development.
Third, I have installed the correct driver from the Samsung site based on my model number (SGH-I997), yet when I do adb devices from my platform-tools directory (I have tried adb kill-server and adb start-server), I still do not get my device listed.
I am not very advanced in terms of working with Android and have been banging my head against the wall on how to solve this problem, so any and all help guiding me through this would be appreciated.
Thanks!
Try installing this PC Suite ...Samsung Kies http://www.samsung.com/in/support/usefulsoftware/KIES/JSP this would help you to get the exact driver for the device and don't forget to check USB Debugging option in settings.
You also need to mark "Allow Mock Locations "in Development Options in Applications settings of your phone.
Also try enabling ,use as mass storage after connecting your device.
You can check if your device is detected in device tab of DDMS in Eclipse.
Even trying all such things ,it does not work try connecting your device 2 or 3 times ,restarting eclipse and enabling USB Debugging and mock locations again
