I've installed the RTM build of VS2015 with the Android Tools. I can launch the emulator manager and see the list of installed images. When I click the green triangle to start an image, it shows a progress bar and the text "Launching emulator..." and XDE opens up with the message "OS is starting"
After a while, XDE shows an error message:
[Window Title]
Visual Studio Emulator for Android
[Content]
The emulator is unable to connect to the device operating system:
Couldn't set up the UDP port.
Some functionality might be disabled.
[Close]
Strangely, when I look in Hyper-V Manager, the image seems to be running perfectly.
I have already removed the GuestDisplayNameProvider line from xdesku.xml, which was previously resulting in the error: "Failed to read from dev/hw_random: No such device" on startup.
So I finally fixed this issue, it's because I had broken virtual ethernet adapters. Here's what I did to fix it.
Remove Hyper-V through by turning off the windows feature.
Reboot
Open device manager and go to network adapters.
Remove all of the Hyper-V Virtual Ethernet Adapters
Enable Hyper-V through by turning the windows feature back on.
Reboot
Try to run your emulator, you should notice that the Virtual Ethernet Adapters are recreated and working.
This occurred after disabling then re-enabling Hyper-V. To fix the problem:
Delete all virtual switches in Hyper-V Manager, delete all virtual machines in Hyper-V Manager, uninstall all profiles in Visual Studio Emulator for Android. Then reboot the machine (just to be sure). Then, open Visual Studio Emulator for Android, download the profile you want, and then click "play". The relevant switches, VMs, etc will all get created fresh now.
Go to "C:\Program Files (x86)\Microsoft XDE\10.0.10586.0\SKUs\Android\" and open xdesku.xml with notepad and remove the following line: GuestDisplayProvider="VsEmulator.OpenGLGuestDisplay.
If your emulator freezes on "OS is starting" but Hyper-V shows "OS" , follow the following link:

It works for me.
Add new virtual switch helped me a lot.

I am new to android development and was trying to use bluestacks to test my apps (as my pc won't run the emulator fast) but the bluestacks emulator is not being detected by android studio.
I started bluestacks and then ran my app. On the choose device dialog it doesn't show bluestacks.
I looked up in device monitor, but bluestacks wasn't detected there.
I also tried using adb kill-server, adb start-server, adb connect 127.0.0.1
but that didn't work as well. It says "connection could not be made as the target machine actively refused it".
All the solutions given in the other related stackoverflow post don't work. Android studio won't recognize bluestacks.
Please Help !!
Try in command prompt "netstat -anb" with administration privileges. Check if there is 127.0.0.1 5555 Estebalished.
If everything is OK then temporary disable firewall and type"adb connect 127.0.0.1:5555" should work.
i too have also gotten the error "connection could not be made as the target machine actively refused it" recently (when i tried to connect to adb using command prompt)
Trying with -> adb connect localhost:5555 or adb connect 127.0.0.1:5555 would not work. You need to identify your bluestack device ip address. You can identify the ip address using the preferences in your bluestack emulator setting. (where you enabled ADB in bluestack).
I did the following to resolve the error you had encountered and successfully connect Android studio to Bluestack. please try the following steps. (I am using windows 10, Android Studio 4.0.1, Bluestacks 4.200.)
find your android studio sdk platform tool folder. For me its is
custom installed in my D drive. for example->
D:\AppData\Local\Android\Sdk\platform-tools
right click on adb.exe
and run as administrator. (click on yes if a pop up ask if you would
like to make changes to your devices. After that you would only see
another pop up that suddenly disappear.)
open Bluestacks. Run your selected emulator (samsung/pixel etc). Ensure that
you have enable "Enable Android Debug Bridge (ADB) in the emulator
preferences.
open command prompt. cd to your platform tools folder path.
enter the following command->adb connect xxxxxxxxxxx where xxxxxx is your
device localhost ip. (see attach pic. My device ip is
127.0.0.1:xxxxx hence my command is ->adb connect 127.0.0.1:xxxxx
continue with the following command->adb devices you would see your bluestack
emulator device. same ip listed.
open your android studio. You would be able to see your bluestack emulator
[
i don't know if you fixed the issue or not but it's pretty simple to use bluestacks, if you see this screen when you open it like this all you have to do is run the app in android. it happens where android doesn't detect it because it wont see it as a device you either wait or try to get that screen (that sort of refreshs)
Just Need to do this!
Go to the SDK folder that you have got in your computer,then open the "platform-tools" folder,then open the "adb.exe" as administrator.
then try the BlueStack emulator.
if u got problem to connect with blue stack through android studio then follow following steps
in run(windows+R) put '%localappdata%\Android\Sdk\platform-tools' and check adb.exe is working correctly or not
If not then download file from
https://www.microsoft.com/en-us/download/confirmation.aspx?id=49093 which is
Update for Windows 7 for x64-based Systems (KB2999226) (related OS)
and install it.
allow adb.exe as exception in your virus scan software don't treat this exe as malware.
start your blue stack emulator.
go in setting of blue stack emulator go in preferences click checkbox 'Enable Android Debug Bridge'.
go to this location %localappdata%\Android\Sdk\platform-tools and run cmd through this location.
put command 'adb connect localhost:5555' press enter in command prompt.
start android studio then run project through play button popup will come with virtual device list, it will show your emulator's device.
...happy coding
I'm not able to install Emulator in my laptop. It's showing an error, could someone suggest what should I do ? I've attached the error screenshot :
You need to install HAXM from the SDK Manager and go the root directory and install the HAXM and then you are good to go!!
This problem occurs when the virtualization technology is not enabled for your device.It can be solved by enabling it.
(For a windows based device)Go to
Control Panel->Programs and Features->Turn windows feature on or off->Hyper-V
Check this option and reinstall.
If this option is not present in your computer then try doing from boot-menu:
1.) Press F10 (Computer Boot Up)->BIOS->Security->System Security-> Virtual Technology (VTX)
Enable
Save and Exit
2.)Goto sdk Folder:
F:\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager
Run intelhaxm-android.exe
You will see a dialog box which says, "Completed Intel Hardware Accelerated Execution Manager Set Up Wizard. Click the Finish Button to exit the wizard"
Once this works, open android studio, and try running the emulator.
my avd is not running on eclipse. sometimes it says, haxm is not installed. sometimes just a black screen appears and nothing happens. why is this happening? i tried to reinstall but nothing happened. but it was working few days ago and suddenly this is happening. i cant run my apps on emulator. how to fix this?? i am using a windows 10 tech preview 64 bit. i have tried to run eclipse on my laptop windows 7 64 bit with different version, same problem. so there must be some technical problem that i dont know, pls help.....
HAXM, the Intel Android Virtualization Technology is incompatible with Hyper-V. Turn off Hyper-V and give it a go again. Hyper-V will often be installed if you have installed Visual Studio with Windows Phone tools. Or maybe Hyper-V is just turned on somehow?
Or from an admin command prompt run the following. Note to get an admin cmd prompt, right-mouse the windows icon, click Command Prompt (Admin ).
To turn off Hyper-V run this: bcdedit /set hypervisorlaunchtype off and then reboot
To turn Hyper-V back on, run this: bcdedit /set hypervisorlaunchtype auto And then reboot
You can turn off Hyper-V in the services menu (type "Services" in the Search thingy), and also use the Services menu to turn it back on. Even though it may not be necessary I still reboot after doing it this way.

Android emulators are not super reliable. Can you try using genymotion (http://www.genymotion.com/). It is free for personal use and it is super fast.
Open the Android SDK Manager from Eclipse tab "Window", check the box at the very bottom in the Extra folder that says "Intel x86 Emulator Accelerator (HAXM installer)" and click Install package. I think you are using an emulator with VM Acceleration.
whenever i start eclipse or android studio an emulator is constantly running in the background. when i try to turn it off it restarts again immediately. no matter if i work with a real device or an emulator i have created, this other emulator is not stoppable. in the android debug monitor this emulator is listed as emulator-5554 - Online - ? [2,3,4, debug] (Version API10). i never created or used this emulator, and there is no place to find and delete it.
actually i am able to work with eclipse or android studio with that annoying emulator, but it seems to slow down the performance and i would like to get ride of it.
Were you using BlueStacks back then by any chance?
It uses the port 5554, and that might have been your problem too!
It happened to me as well and found the solution in another question:
Eclipse Android Emulator-5554 is always displayed
Strange, but should be able to kill a "hidden" emulator instance from the command-line by connecting to its console, i.e.:
telnet localhost 5554
kill
Replace 5554 with your emulator instance's number.
I use AndroVM. For me its perfect.
Todo is:
install VirtualBox first
download AnroVM
file will open in VirtualBox
start the machine and set USB debug on (settings >> dev. options)
in commandprompt goto your "sdk\platform-tools" type adb connect 192.168.15.101
When it's ok you will see your device in Eclipse.
edit: When your Eclipse is not working well, just download a new bundle again
When I use HAXM with an intel atom cpu for an avd, my avd doesn't show up as a connected device in android studio. This essentially means that everytime I rebuild my project, the emulator has to launch a new emulator instance from scratch instead of running the re-built project on the already running emulator. How do I fix this?
I had to reset the adb. Do this by opening android device monitor aka android debug monitor aka ddms and then right clicking the dropdown arrow and then clicking "reset adb". You can also do this in terminal as shown here: Android Emulator not seen in Device Chooser
