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 searched for the answer before asking. They weren't satisfactory.
Environment and what I did so far:
My device is Xiaomi Redmi 2. I have enabled USB Debugging in my device.
My phone uses a Cyanogen mode with 5.1.1 installed ( Lollipop ) and not 4.4 ( Kit-Kat )
It is also connected as a media device as asked in an answer
I'm running android studio on Windows 8.1.
I don't want to change my OS if that's possible.
Minimum level it is set to be API Level 15 so all the devices with ICS will be supported.
Questions:
Do I need to install a driver and if yes, what driver do I need to install to make it work?
If I need it how do I use it?
Where do I get it from?
I have to mention that I am using this site for the first time so I might not know the best way to search.
Any tips on that?
It may just be that the MTP mode isn't supported. Try changing your usb connection to PTP in your device's usb connection settings.
Taken from the Android Studio User Guide.
If you are developing on Windows and would like to connect a device to test your applications, then you need to install the appropriate USB driver.
Find the appropriate driver for your device from the OEM drivers table.
Once you've downloaded your USB driver, follow the instructions to install or upgrade the driver, and whether you're installing for the first time or upgrading an existing driver.
Update your android studio and your android project :
Android Studio > SDK Manager (top right of the ide) > Launch Standalone SDK Manager > uncheck the 'installed' checkbox > make sure you have all the recommended updates, tools and apis installed to your development machine.
Update your android project manifest file (AndroidManifest.xml) on about line 20 usually to match the target SDK version you want to build for :
You have to install ADB USB driver manually

I am doing some applications using Android + Eclipse to run on tablets. I have had too much trouble with the tablet emulator, so I would like to try my code (apps) on a real tablet. How can I do this? I have a Samsung Galaxy Tab 3. Do I need to install the adt-bundle on it?
I'd appreciate any input.

You just need a usb cable to connect your device to your pc.Go to the above link for more info
check this it may help you Run on a Real Device
Here is a copy paste, but check the link it's really good and well explained :
If you have a real Android-powered device, here's how you can install and run your app:
1-Plug in your device to your development machine with a USB cable. If you're developing on Windows, you might need to install the appropriate USB driver for your device. For help installing drivers, see the OEM USB Drivers document.
2-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.
To run the app from Eclipse:
1-Open one of your project's files and click Run from the toolbar.
2-In the Run as window that appears, select Android Application and click OK.
Eclipse installs the app on your connected device and starts it.
Or to run your app from a command line:
1-Change directories to the root of your Android project and execute:
ant debug
2- Make sure the Android SDK platform-tools/ directory is included in your PATH environment variable, then execute:
adb install bin/MyFirstApp-debug.apk
3-On your device, locate MyFirstActivity and open it.
I have run android application on my Device. I want to stop this running application using DDMS.
On windows, I can see threads which are running on Android Device. like following image
But on Mac OS X, I am missing such option, How can I get these ?
I see that it's not the same device (4.1.2 vs 4.3) . Did you enable your device as debuggable?
It's in the developer's options and then check USB Debug option.
EDIT: See here how the security of USB debugging was improved since Android 4.2.2
I think when you will select a device then after only it will enable that option. From your screenshots it is clearly seen that you have selected a device in Windows Platform while in Mac you haven't select it.
I have a D2-721 Android 4.1.1 Tablet. I have installed all the drivers for it. I have connected the tablet to my pc and everything is normal except eclipse. I can even Export my APK from Eclipse to my tablet but I cant run as android app from eclipse. My phone works fine. Eclipse sees the phone but not the Tablet. Is the problem my SDK? IS there something special I need to connect that kind of tablet to Eclipse? i have version 17 of Android SDK by the way
Make sure you have enabled USB-Debugging on your device. It's step 2 as described here:
http://developer.android.com/tools/device.html#setting-up
You need to do some magic to get it all enabled.
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.
Did you install the OEM Drivers? and you need to install the appropriate USB driver.
If already installed then need to update OEM driver
Had similar problem with Nexus 7. Try this, connect the device, then swipe down your notifications on the status bar (left side), tap on Connected as a media device and change that to Camera (PTP).
