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'm running windows 8.1 and having a Google Nexus S as Android device.
Debug mode is enabled and I can add/delete files on the device so windows recognizes the device. When I want to compile and run my Android program eclipse says "No compatible targets found."
Can someone help me? I also did a factory reset and rebooted my pc.
Factory reset generally means, that USB debugging is turned off again. Turn that on and check once again.
You need to plug in the device then go the device manager in windows. Uninstall the driver of the google phone. Then install it again but point to the Android SDK delivered drivers. Thats it.
The device manager shows that i have no drive for nexus one (it shows a yellow question mark).
Therefore, windows doesnt identify nexus one..even though i can open the folder of the android when i connect the device..
Even HTC Sync application says that no devices is conencted, even thought the device is connected to the pc.
What do i do?
ps. all the settings on android were taken care of..application debuggable mode and allow unknown applications are ticked. The SDK manager is fully updated!!!
UPDATE:
I go to the device manager and tell it to look for the driver here:
D:\android-sdk-windows\extras\google\usb_driver
Thats what the android developer tells me to do:
http://developer.android.com/sdk/win-usb.html#WinXp
It didnt work..cause i havent got the folder:
<sdk>\google-usb_driver\.
The guide tells me:
Click Browse and locate the USB driver folder. (The Google USB Driver is located in <sdk>\google-usb_driver\.)
Where is teh usb driver that was installed by the sdk manager?
you have to install the driver for you phone ! for the nexus one the driver can be downloaded form the SDK Manager, in the Available packages under Third party addons/Google inc/Google USB Driver Package
My Application is working properly in emulator. I am running the application in the device using the ".apk" file. But it is not working properly. So i want to test the application in the device using Eclipse logcat. How to connect the Real device to the Eclipse for debugging the application in the device. I follow the steps of this link "http://developer.android.com/guide/developing/device.html" . i am facing the problem after setting the path (i.e,The Google USB Driver is located in \google-usb_driver). The error is the hardware is not installed. How to handle this. My device is "Samsung Galaxy Apollo GT-i5801". Please can anybody help me.
thanks
Samsung has a generic driver for various mobile phones. You need to download and install usb driver from this url. After installing the driver and connecting the phone to your computer you need to configure eclipse so that it deploys & runs your program on the device.
In your phone, be sure you have enable the debug mode (Settings -> Applications -> Development -> USB debugging). If you enable it, and with eclipse open, when you connect the phone to the computer, it tries to install the device. Usually, there's no problems,but if there's any, just download the drivers.
Follow the answer provided by Finuka. After you connect the phone, open the DDMS perspective in Eclipse. Any connected phone or emulator will be listed there. You will also see hooks to running apps on those devices. Select your phone+app to see LogCat.
