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'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 updated from Mavericks to Yosemite and now I can't use any Genymotion device anymore.
You can see the devices in Eclipse, but when you want to run an application you can't select one of these devices.
I've already re-installed Eclipse, Genymotion and Virtualbox...
The Genymotion Virtual Devices Manager shows a Nexus 5 which is stated 'On'
When I want to run my application, there is no Nexus 5..
This is a bug in eclipse - OSX yosemite, what you need to do is in the Android Device Chooser Window, try to RESIZE THE SERIAL NUMBER TAB and you will see the genymotion emulator that is running
If you don't see it, or the Android Device Chooser Window doesn't appear, check three things before running again:
Developer Options is enabled from settings (by repeated touching 7
times the build number in about phone), even though developer
options is available in the list of apps in genymotion emulator
In Settings>Security, make sure "Unknown Sources" is enabled
Go to Run Configuration (for Android app), select the Target Tab, Enable Always prompt to pick device and hit apply.
Additionally I downloaded the jar files from Genymotion Download Page manually and replaced it in the plugin folder of eclipse.
EDIT
FYI, a bug has been opened in AOSP's issue tracker.
Issue 78436: [ADT/Eclipse] Cannot see my device in the Android Device Chooser dialog even though it is there in the Devices view
At bottom of this page, there is a link to 'Vote for this issue' ...
I can resolve this problem by connect a real device one time.
Please scroll down and see list of devices which is connected to ADB.
I had a similar issue, but my problem was that the emulated device was running Android 4.3 (SDK version 18), but the app had android:minSdkVersion="19" so since no compatible device was found the list was empty.
Double check your emulated device version, and the minSdkVersion number, to make sure it's compatible.

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 just want to test my android application in my Nexus 7 device in my mac.
I connect the Nexus 7 tablet to my mac through USB connection. While I try to run , its status is offine.
I also tried to run my android application in Windows machine. There I installed one driver for Nexus 7. Windows detect the Nexus and I can able to run my application in Nexus.
Is there any special driver needed for Mac?
Please provide me the best way t overcome the issue
several suggestions :
1. You have to authorize every machine you use since android 4.2
2. Check if you need to update your sdk.
You have to update to the proper API level and to usb driver (under extras -> Google usb driver). Then change the driver of your nexus 7 to the new one. You can find it at your android-sdk folder.
3. If that won't help you call to : 'adb devices' (Windows commend - I guess that it has to be the same at mac)
Did you check on your device:
Enable USB debugging on your device.
On most devices running Android 3.2 or older, you can find the option under
Settings > Applications > Development.
On Android 4.0 and newer, it's in Settings > Developer options.
Note: On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options.
