Android Studio Bumblebee (2021.1.1) was released stably on 25 January 2022 bundled with a new Device Manager (accompanying new support for Android 11+ device debugging over WIFI). I jumped on this stable release, updating from Android Studio Arctic Fox (2020.3.1 Patch 4).
Unfortunately however, since updating, physical devices/handsets don't remain connected to Android Studio for the purpose of debugging. I can confirm that the issue was introduced from Android Studio Bumblebee onwards (occurring in Beta and Canary builds also). I've reproduced the issue on Android Studio Bumblebee (Stable), Chipmunk (Beta), and Dolphin (Canary), but Android Studio Arctic Fox (superseded Stable) continues to work just fine.
The issue occurs soon after opening Android Studio (Bumblebee+) with one of my physical devices connected. Everything appears fine initially and I may even have enough time to deploy my project to the handset, before the device disappears from Android Studio (as if I'd physically disconnected the USB cable from my computer or from the handset itself).
I've tried a fair few things in an attempt to determine a root cause. These include testing:
With different USB cables.
With different handsets (both varying makes and models).
With various versions of the Android Studio IDE (as mentioned above).
Plugging the USB cables into different USB ports on my computer.
Rebooting handsets and my computer.
Restarting Android Studio.
Invalidating caches and restarting Android Studio.
adb kill-server then adb start-server.
Revoking/reaccepting USB debugging authorization.
Reinstalled build tools/platform tools, and ADB.
A great number of further possibilities, to no avail.
I searched and read through remotely similar issues, including (but not limited to) these:
Android Studio Arctic Fox (Adb) - Connected Devices are being disconnected after some time
Android debugger continually disconnects
This particular comment in one of the above issues clued me onto a possible root cause:
I have been fighting for a few days with adb not seeing my device. After trying many other posted solutions, I discovered that the issue was with Chrome also trying to connect its debugger to a web view. If Chrome is connected using chrome://inspect, then adb seems to disconnect. Quitting Chrome resolves the issue. Then I can connect with Android Studio and then restart Chrome and reconnect. Hope this helps someone else.
However I've been unable to do anything with the above discovery, other than close Google Chrome, and hope for the best. Obviously this isn't an ideal solution. It appears as though the moment Google Chrome shows the connected physical device in the chrome://inspect/#devices page, the physical device promptly becomes unavailable through Android Studio.
I've jumped back to Android Studio Arctic Fox (2020.3.1 Patch 4) for the moment, however this brings with it other issues (my current core project targets the latest SDK version, which requires the updated IDE).
Absolutely any help with this would be insanely appreciated. I've exhausted just about every avenue that I can think of!
I solved the problem by disabling
Settings -> Build, Execution, Deployment -> Debugger -> "Enable adb mDNS for wireless debugging"
I'm developing for android for almost 10 years now and I'm struggling with this annoying issue regularly - while debugging with android studio and a physicals device the device suddenly disconnect with no apparent reason.
sometime it gets into a loop of disconnect/reconnect for a few times
During the years I change PC, Devices, cables - but always at some point the problem persist.
I think there are many reason for this problem, including:
Bad/old cables
Erosion of the USB socket of the PC or the device
bugs in ADB/Android Studio/Android device
I tried to work with WIFI plugging, most of them didn't work, the one who did work, solve the issue, but were ridiculously slow
I search the web many times and couldn't find an answer that solve the issue for me, partly because there are many different reason for this, which makes each answer very specific.
Therefore I suggest that if any body find a solution for his specific case, please add it as an answer here for the the benefit of other.
Currently I found the following solution: after I bought many cables, I was finally able to find one that doesn't disconnect as much (I actually borrowed it from my work...)
AND I also use Vysor, which project the android screen to my PC, so that I don't have to move or touch the Physically device, which reduce the problem to almost never.
I also noticed that it happens more when the battery is 100% so I try to keep it below
SOLVED this with changing usb on pc from USB 3.0 port (blue type) to USB 2.0

Been facing this problem a lot of times, finally posting it on SO.
I start debugging my app with some breakpoints and it works properly for some sessions. Abruptly after some time, I will reach a breakpoint and the debugger shows Evalutaing... and it won't evaluate until eternity.
If I click resume or step buttons, the program won't proceed and the only way out is to disconnect and reconnect the device and start over.I am using latest stable Android studio.
Android 9 emulators work without issues. But I do get network connectivity issues on the P emulators. If I debug on Android O or lower devices, it works like charm.
Isn't anyone facing this issue? It's really frustrating when you don't have a device running lower Android version. Is downgrading to Oreo the only solution here? Any pointers will be appreciated.
Devices: Mi A2 (Android 9), Pixel 2 XL (Android 9).
Cables: Provided by both OEMs and tested to work perfectly in charging and data transfers.
Mode of debugging: USB
OS: MacOS Mojave and Ubuntu
Updating Android Studio to the next stable version fixed the issue. The debugger does not get stuck any more.
Today I downloaded Android Studio for my Debian Testing system. I wanted to run a HelloWorld application but weren't able to run it. With adb I can install it without having any problems.
However, if I try to do it with Android Studio, it gets stuck on 'Installing APKs'. The same happens when I try to start it in an emulator (gets stuck on 'Waiting for target device to come online').
My device is a Samsung Galaxy S3 with LineageOS (Android 7.1.2) and root permissions. Android Studio recognizes my phone properly.
What I've already done:
installed openjdk
set android_home
installed all the SDK-platforms since Android 4.3 and Android Emulator from SDK tools
enabled USB-debugging
tried with MTP and PTP
tried another emulated phone
installed lib32stdc++6
restarted my computer
and probably much more
I tried to do it the whole evening and couldn't find a solution. Is there something Debian-specific because I can only find instructions for Ubuntu? I have never experienced anything close to this on other systems.
Thank you in advance.
EDIT: I am now able to use my phone to run the android application by using USB 2.0 instead of USB 3.0! Is that a normal behavior since it works with native adb? I mean, if I buy a new PC after some years which has got only USB 3.0 ports, will I not be able to use phone debugging with Android Studio or is this just an issue? It is still known since 2014 (https://stackoverflow.com/a/9548311/8292104).
However, I still cannot get the app running on an AVD. I changed graphics to software, now it shows the phone but the screen remains black and the phone won't start. What can I do to fix it?
Try to completely delete and install Android Studio again, I think that it will solve the problem
Another possible solution that worked for me is to, in the application, go to
app - build - intermediates - split-apk - debug - slices
and then delete all of the contents within this folder. Then again, this only worked for me, so I would duplicate the document in case of corruption.
I am using the latest version of Android Studio(2.1.2) at the time of writing this post . The problem that I am experiencing is that the ADB instance used by Android Studio doesn't seem to be able to find my Galaxy Core Prime device (SM-G361F, stock Android version - 5.1.1). It can connect to an emulator just fine.
What I had tried (most of these multiple times):
enabling/disabling developer options
enabling/disabling USB debugging
revoking USB debugging authorization
changing MTP to PTP and vice versa (my device doesn't allow deselecting both options, one must be chosen)
reinstalling the drivers
powering on and off both the phone and the PC
installing Samsung's Smart Switch software
using different USB ports
trying out different Android Studio versions (x86 and x64 with the latest respective JDKs)
This is what it looks like in Android Studio:
I had installed the official Samsung's USB drivers from here.
This is what the Device Manager is showing (Windows 7 64-bit SP1):
Afterwards, I've also tried installing the Universal USB drivers from here.
This is what firing up its installation of ADB looks like:
It has obviously successfully found the device.
My device also politely prompted me to allow the PC to connect to it using a generated RSA key which never happened with Android Studio.
The only thing I've not tried is installing Samsung's Kies software.
I really don't know what is the problem here.
Maybe I should just give up and instead use the emulator but it is a damn shame not to be able to debug on an actual physical device, if you ask me.
Thank you in advance.
Android in general does not support all phones for a debug connection. I have a samsung s6 and for me that works. I don't know about the Core Prime though. However, in most cases(in my experience):
The phone does not support the connection
You did not install all the required files in terms of the android SDK you might have not gotten the latest update that supports more phones
The OS is not supported - Mainly caused because Samsung and a lot of other brands insist on having their own updates. And some times they - on purpose or by accident - forget to support USB debugging for developers.
My tablet did not support the USB debugging connection untill it reached android 6.
The cable is a charge-only cable (yes, those exist for some reason). Try with a different cable
You don't have the necessary drivers. Make sure they're installed
It might be circumstantial that your phone model does not support the connection for some reason, but it is really hard to tell. The only way to get proper help is to contact Samsung customer support, but in my experience it is just a waste of time. They don't know their own products. If you try with another device it might work.
After some continued tinkering I managed to get Android Studio to recognize my device. All I did was adding the path to the ClockworkMod's ADB .exe to the PATH environment variable. That seems to have done the trick as Android Studio now allows me to run the application on my device even though it is still running its own instance of ADB (located in the platform-tools folder).
It might be completely unrelated but I'm not considering undoing the modification made to the environment variable.
Here is the proof:
Since I read the news about Xamarin now being "free", I immediately installed Visual Studio 2015 Update 2 and the Android tooling (NDKs, SDKs for 19-23, Visual Studio Emulator for Android dated January 2016) to start working on an Android application.
Excited I launched the emulator from Tools -> Visual Studio Emulator for Android and installed the profile that is the best match for my own phone. Since my phone is on Android 6, I decided to get a profile for API Level 23 / Android 6.
Since I had already enabled Hyper-V a few months ago, the installation for the profile only had to add me to the Administrators group and create 2 network adapters.
So far, so good.
Upon starting the emulator, it would stay at "OS is starting...". I figured I'd wait a while. I figured I'd wait a while longer too. After that, I gave up the possibility of it going to work and started investigating.
I also tried other profiles, a few others from API Level 23, one from 22 and one from 19. Only the ones from API Level 23 did not work.
The following steps are what I came up with so far by Googling etc. I tried them in all sorts of combinations:
Rebooting
Disabling / enabling Hyper-V
Removing vEthernet adapters (through the Hyper-V Manager).
Running XDECleanup
Allowing XDE through my Windows Firewall as application (incoming)
Restoring the emulator software in Programs and Features
Enabling / disabling "Processor Compatibility" in Hyper-V Manager.
This is the data I've gathered so far:
A screenshot of the error message that the emulator gives after waiting a long time (10 - 15 minutes, maybe a little longer)
A screenshot of the last part of the log when being connected to the Android 6 VM:
A screenshot of the last part of the log of a working VM (this one's from an Android 4.4 VM):
Responses I've got so far from Microsoft:
-Those errors are normal
-And the only step I've tryed which they told me to, and I don't see here, it's this one:
On Hyper-V Manager, check the option for compatibility under CPU section
Besides from this, just make sure that on Hyper-V you get only 2 switches, the one you use to connect to the internet and the one that the VS Emulator for Android creates, I haven't got any results, but if you try, maybe you will.
In my case, I was mucking around with the VS emulator's virtual switches and had the network adapters in the wrong order.
After I moved the Windows Phone Emulator Internal Switch (Created when first running the VS Emulator) to the first Network Adapter slot in my settings, the emulator started up just fine. Apparently, order matters.
Had the same problem but got mine to work after trying a lot of things from different threads.
In the end I think this did the trick for me:
I added "c:\Program Files (x86)\Microsoft XDE\10.0.10586.0\xde.exe" as an exception in the firewall.
(i also switched of the firewall, but was probably unnecessary)
Temporarly disabled the WiFi device
Uninstalled VirtualBox
Removed all Virtual Switches in Hyper-V
Executed XdeCleanup.exe
Started the emulator again and it started up successfully!
Swiched of the emulator and enabled Firewall, Wifi device.
The emulator still starts successfully every time!
Thanks to all for sharing!
If you're using Xamarin, it's recommended that you use Xamarin Player. It's not Xamarin exclusive, it's just a much faster Android emulator. I use Android Studio, and the Xamarin Player is still faster on boot and launch than the default. This is just my recommendation to you, I have no clue how to fix your Visual Studio emulator, sorry.
I've played a lot with this and realized that I have had manually configured paging file on Windows. After restoring it to default all worked perfectly without messing with the virtual switches or adapters.
Just make sure that you have all Windows memory etc. settings set to default.

My problem was that the system image was missing for the emulator.
When I opened the android virtual device manager it had an exclamation mark next to actions(i had to download the system image via the download link).
I had the same error message. The solution for me was:
Uninstall all emulators in the Visual Studio Emulator for Android
Check in Hyper-V-Manager if there also no instances
Unistall Visual Studio Emulator for Android
Run xdecleanup.exe (C:\Program Files (x86)\Microsoft XDE)
Uninstall Hyper-V from Windows features
Removed virtual ethernet adapters through uninstalling in Device Manager
(be sure to display disabled devices too)
Install Hyper-V from Windows features
Install Visual Studo Emulator for Android again
Download and install your emulator/profile
Run the emulator and have fun :-)
It seems there was a problem with the virtual switches and Hyper-V. The correct settings for the adapter looks like these:
Hyper-V-Manager:
Device Manager:
Network adapter:
Ethernet:
vEthernet (Virtueller Switch: Intel(R) Ethernet Connection (2) I219-LM #2):
vEthernet (Internal Ethernet Port Windows Phone Emulator Internal Switch):
Emulator network settings:
I have installed the and adb driver on my android device which is yu-yuphoria
now in device manager my device is listed as android adb interface . But when i run any app on android studio that device is not listed . I have changed the usb mode from media to camera again installed the adb interface and restarted both system and device still the device is not listed in android studio.
i have spend hours in fixing the problem but cannot do.
few days earlier there was no such problem but now it came from no where
any possible solution
I had all those weird problems with Windows showing perfect configuration but devices not visible. With three different phones, I always fixed it with this free tool (from XDA I believe):

Ofcourse this will not help if it is actually a problem with Android Studio.
