BlueStacks - Android Virtual Devices don't get assigned IP and port

I just installed BlueStacks latest version using the default configuration.
Then I ran the Android SDK command:
> adb devices
and I got:
List of devices attached
emulator-5554 device
As you can see, the BlueStacks doesn't get an IP and Port.
I cannot deploy from MSVS2015 to this AVD and I think that's the reason, because I also have Genymotion AVD installed which has an IP and Port and this is visible by the MSVS2015.
List of devices attached
192.168.189.101:5555 device
How can I make the BlueStacks get an IP and Port for the AVD and then deploy to it from MSVS2015/Xamarin?

Try this: run netstat -a in your command prompt. If you see 127.0.0.1:5555 running, then everything is okay, else disable your firewall. Then run adb connect 127.0.0.1:5555. Hope it helps.

For me the following did the trick: On the Bluestacks machine (assuming it is a Windows machine) run cmd as Administrator and type in:
netsh interface portproxy add v4tov4 listenaddress={ip.of.bluestacks.windows.machine} listenport=5555 connectaddress=127.0.0.1 connectport=5555
Now you can connect from remote machine using
adb connect {ip.of.bluestacks.windows.machine}:5555

How to use adb with genymotion on mac?

I am using cordova to build apps for android, on Mac OS X 10.9.4.
I am using genymotion to create virtual devices.
Yesterday I was able to get 'cordova run android' to get my apps to run on a genymotion virtual device.
Today, I thought I repeated the steps I took yesterday, but I can't get it to work.
I start the adb server (with genymotion not running) with
adb start-server
adb server starts up fine:
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
I can see it's there
lsof -i tcp:5037
adb 19131 bw 7u IPv4 0x3c0bc54e449e35f5 0t0 TCP localhost:5037 (LISTEN)
There's no devices attached
adb devices
So far so good
Now when I start up genymotion, and start a virtual device, my adb seems to have been killed and cannot start because the virtual device has apparently killed it and started its own adb instance
unknown-6c-40-08-9b-25-2c:todo bw$ adb devices
adb server is out of date. killing...
cannot bind 'tcp:5037'
ADB server didn't ACK
* failed to start daemon *
error:
This now gives me no way to add the device to adb so that I can access it by doing
cordova run android
This command now fails, because it can't find a running device.
I tried running adb start-server as root, so that genymotion couldn't kill it, but then the genymotion virtual device wouldn't start up.
What gives? Grateful for any ideas.. Thanks!

Well, it's not entirely satisfactory, but I have got it to work.
When I change the settings in genymotion under the settings->adb tab to reference my android sdk rather than the built-in genymotion android tools, everything works fine. That's great, but I don't understand how it can have been working yesterday before I changed that setting. Oh well. Hopefully this will help someone.

ADB over TCP - Devices are connected and online but installing shows Error: Device not found

Good day,
I've been using a VMWare android machine and installing .apks on it but after my computer was unexpectedly shut down and tried to re-install a package I've been having the following problem:
$ adb -s 192.168.1.2 install 'myapp.apk'
error: device not found
- waiting for device -
However I was able to connect the VM using adb connect 192.168.1.2 which is the ip currently assigned on the android, (seen it on ctrl+f1 netcfg) and then shows:
connected to 192.168.1.2:5555
$ adb devices
List of devices attached
emulator-5554 offline
192.168.1.2:5555 device
so it appears to be online.
Troubleshooting steps taken before posting:
$adb kill/start-server
Reconfigured the VM Network (I have it bridged and Internet connection works fine).
-Suspending/Shutting down and Restarting VM.
-Restarting Internet connection (Router/PC connections)
Kindly assist with situation or post links of another issue related to mine that I probably did not find (sorry for that..)
Thanks!
Edit: I'm using Fedora as OS, Eclipse for developing

When using an ADB tcp target, the device name specified in the -s parameter must include not only the IP address but the port as well, for example:
adb -s 192.168.1.2:5555 install 'myapp.apk'
(As the android emulator actually talks over TCP behind it's "emulator-####" name, one can test this by connecting to an emulator at the loopback address using the control port plus one, ie, "emulator-5554" can also be reached as a vanilla tcp target via adb connect 127.0.0.1:5555 and then you can install on it with adb -s 127:0.0.1:5555 install whatever)

Debug device connected by USB to VirtualBox's host, from Android-Studio inside VM

I am trying to get mono for android (aka monodroid) working within a windows 7 virtual machine on virtualbox but I am having issues with the adb connection to my phone. When I run "adb devices" to list the devices present it show up no problem, but when I attempt to run an "adb install", logcat, or push it hangs. Currently there is a bug in virtualbox which applies to this but I was hoping someone more knowledgeable than myself would have a workaround.
https://www.virtualbox.org/ticket/6620
Of coarse non of this would be an issue if Xamarin released a linux port of their product or if I got familiar with Java, but I suppose those are slightly different issues.

Brian, one workaround you might consider is to make your VM host an ADB host as well. Then you can just connect your VM client to it over TCP / IP. Here's the general idea for that setup:
Install the Android SDK on the host machine. You should only require the platform-tools package which includes adb.
Don't allow your VM client to take ownership of the Android device, so disable any VirtualBox USB filter rules you have and it also wouldn't hurt to then detach and reattach the device.
From your VM client, run adb kill-server. Make it a tskill adb for certainty. If you have any running instances of Eclipse, you'll want to shut those down first because it'll actually launch adb in the background. Don't skip this step.
From the host, execute adb devices. If all goes well (and it should), you'll see your device listed. It should look something like this (note the port number and sorry for the mangling):
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
015d2994ed200409 device
At this point, your host should have an ADB server running at port 5037. You can check this from the VM client by running telnet 10.0.2.2 5037, where 10.0.2.2 is the default IP for VirtualBox hosts and 5037 is the default ADB port noted above.
Now you must either forward the ports from your host to your VM client, or otherwise connect ADB directly to your host IP:port. If you're like me, you'll find the ADBHOST and ANDROID_ADB_SERVER_PORT variables to be poorly documented and easy to screw up. For this reason, consider simple port fowarding over ssh (maybe via Cygwin) like so from the VM client:
autossh -nNL5037:localhost:5037 -oExitOnForwardFailure=yes 10.0.2.2
Finally, run adb devices from your VM client. If you see "daemon not running," it means your port fowarding is screwed up. Otherwise you should see your device and be able to logcat all day. One noteworthy point is that you won't have an adb daemon running on your VM client, except for when you're actually using the debug bridge, of course.
I've used a similar mechanism for debugging devices over the network that are connected to remote machines and it worked well.

Not sure what has changed in VirtualBox since the question was posted, but selecting the usb device from VirtualBox menu Devices -> USB -> DeviceName worked seamlessly. I am working on VirtualBox 5.1.2 r108956.

I was also having trouble with ADB running over VM. I had a Windows 10 host and an Ubuntu 14.04 client. The autossh method did not work for me. I found an easier solution from another StackOverflow question. It requires that both your PC and your device are on the same WiFi network.
On your VM client run the following: adb tcpip 5555
The device will disconnect from the VM because ADB is now in TCP
mode instead of USB.
For the next part you need the IP address of
your device. To find it, simply run adb shell ip -f inet addr show wlan0
Now you can connect to your device. On your VM client, run:
adb connect <Device IP>:5555
From here all my adb shell, logcat, and monkey sessions ran without interruption!

I'm posting this here for people with a setup similar to mine:
Host OS: OSX (10.15.4 Catalina)
Client OS: Windows 10 Enterprise (v1903 build 18362.752)
VirtualBox v6.1.4
Android Studio v3.6.2
To allow Android Studio in client OS (Windows) to connect to an Android phone (using adb) via USB:
Update to latest version of VirtualBox (currently 6.1.4)
Install VirtualBox Extension Pack from here
With the VM powered down, go to Settings > Ports > USB and make sure the USB 3.0 (xHCI) Controller is enabled, then click "OK"
From the host OS (i.e. OSX) open up a terminal and start adb and confirm that the phone is connected by running adb devices
Start up the VM, and from the VirtualBox menu select Devices > USB > [YOUR PHONE] to connect your host OS USB port to the VM
Open up a terminal on the client OS (Windows) and run adb devices to confirm that the adb server is running and can find your phone. You might need to add the Android platform tools to your PATH (mine was at C:\Users\Username\AppData\Local\Android\Sdk\platform-tools). This step might be optional--I suspect that Android Studio might start up adb on its own.
Start up Android Studio in the client OS (Windows) and go to File > Settings > Appearance and Behavior > System Settings > Android SDK > SDK Tools and make sure that the Google USB Driver is installed (see screenshot here)
After I did these things, Android Studio was able to detect my phone and run/debug apps using that device.
Hope this helps!

I had the same problem and it made me search for about 2 hours.I tried several approaches including all above solutions but none of them worked
My situation
My host was archlinux and the guest was windows 8.1 I was running flash builder in windows but the usb debugging wouldn't work and my connected device was nexus 5 so i followed these steps
Enable USB controller from virtualbox menu Machine-->settings-->usb enable usb controller and enable USB 2.0 (EHCI) controller then add your device(click on + button on right side) then start your virtual machine
Now you should download the latest google usb drivers from here and extract it
Go to control panel device manager right click on your device go to driver tab and click on Update driver there should be two option one search automaticly ... and another browse my computer choose the second one and give the extracted file path(check the Included subfolders option) after this your device should be recognized by windows and there will be a message in your android device for allowing access to your device
In my case i should copy the drivers to flashbuilder android drivers path too but maybe for your situation this isn't necessary

I had same problem with VirtualBox 5.0.14 and solution provided by Stephen Niedzielski didn't work for me. If someone is still interested can try this solution.
My environment is:
Host OS: Mac OS 10.11
Guest OS in VirtualBox: Ubuntu 14.04
Device: Galaxy S5 running Cyanomodgen 12.1
Start a wifi hotspot in host OS and connect there the android device, or connect both in a router. In virtualbox set network mode for guest OS to 'Bridged Adapter' and then select name of Wifi adapter. In that way host OS and android device are in same network.
Then, in android device activate 'Developer mode' and enable 'ADB over network', provided from Cyanomodgen. (For devices with original version of android, google how to use ADV over network if possible)
In host OS run 'adb kill-server' and make sure no instance of ADB is running. Then run command 'adb connect 192.168.2.12', ip of android device.
Congrats :) Now you are are able to use ADB with android device to take logcat or pull and push files.

Install the Android SDK on the host machine. You should only require the platform-tools package which includes adb.
Don't allow your VM client to take ownership of the Android device, so disable any VirtualBox USB filter rules you have and it also

At this point, your host should have an ADB server running at port
5037. You can check this from the VM client by running telnet 10.0.2.2 5037, where 10.0.2.2 is the default IP for VirtualBox hosts and 5037 is the default ADB port noted above.
(https://stackoverflow.com/a/12557836/16902966)
and in the virtual machine (Windows):
set ADB_SERVER_SOCKET=tcp:10.0.2.2:5037
Connected device(s): ...\platform-tools>adb.exe devices .

Remote debugging with Android emulator

Is it possible to write the code/compile Android application on one machine and debug it remotely on the emulator launched on another? I'm sick and tired of the emulator constantly eating half of my laptop's CPU.

I haven't previously tried (or even noticed) the adb connect command that cmb mentioned, but I can confirm that forwarding the TCP ports yourself — such as over SSH — works fine.
The emulator listens on two TCP ports per instance: 5554 for the telnet interface and 5555 for control communication with tools like DDMS. So you could probably get away with only forwarding port 5555 (though I've only tried it so far with both). Each subsequent emulator takes the next available even+odd port number tuple (up to around 5580, I think).
For reference, I did the following steps on my local machine:
ssh -NL 5554:localhost:5554 -L 5555:localhost:5555 myuser#remote-server
killall adb; adb devices
I believe the emulator tries to notify a local adb server at startup; hence the need to restart adb in order for it to probe the local 5554+ ports.
Note that the localhost in the ssh command refers to the local interface of the remote machine.
adb devices showed a new emulator — emulator-5554 — and I could use it as if it were running on my local machine.

I realize this question is really old, but I solved the problem slightly differently, and it took me a while to figure out this trivial solution.
I usually use a Windows7 PC or laptop (depending on where I'm working) as my front-end because I like the GUI, however I prefer to do all of my edit/compile/debug on a headless Ubuntu server because of all the command-line power it provides. My goal is to make each windows system as much of a thin-client as possible without any extra services (such as sshd) or firewall holes.
So here is the senario:
System-A: Windows7 system with android emulator running
System-B: Ubuntu server with SDK installed
The problem as described earlier is that the emulator on System-A binds to localhost, not the external ethernet interface, so adb on the System-B cannot access the emulator on System-A. All you need to do is set up remote port forwarding in PuTTY for your SSH connection to System-B. The trick is to check the "Remote" radio button when you create the two tunnels so that the tunnel direction is reversed (tunneling from the server you are logging into to the client you are logging in from).
Finally, connect with adb to "localhost" on System-B after establishing the SSH connection:
System-B$ adb connect localhost
connected to localhost:5555
System-B$ adb devices
List of devices attached
localhost:5555 device
Now you can download images/debug as normal, and it is a trivial matter to switch to a different Windows system if you want to take your laptop out and get some coffee.
In addition, by also tunneling port 5037 in the same manner you can actually forward your adb server connection so that you can connect a real android device over USB on System-A, and download images to it from System-B. In order for this to work, you need to make sure that the adb server is running on System-A, and not running on System-B before starting your SSH session:
First, start the adb server on System-A (command prompt)
C:\> adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
C:\> adb devices
List of devices attached
3435F6E6035B00EC device
Next, kill the adb server on System-B
System-B$ adb kill-server
Finally, restart your ssh session to System-B and verify
System-B$ adb devices
List of devices attached
3435F6E6035B00EC device

Here is how I solved it on Windows. I pretty much followed Christopher's lead, but I can't edit, so a new answer will have to do.
The problem I had was that ADB as well as the emulator was just listening on 127.0.0.1, not 0.0.0.0, for me. Otherwise I would have used TCPMon. I guess this is either different on Windows, or has changed with the latest versions of the SDK. (You can check with netstat -ban.)
I installed WinSSHD on the machine that runs the emulator. (I believe it should work with freeSSHd as well, but I couldn't get a login working there.)
I opened port 22 (TCP) in the Windows Firewall. (WinSSHD might be able to do that for you.)
I created a virtual account in the WinSSHD GUI.
I created a new PuTTY connection from the development machine to the emulator machine and made sure I could connect.
Then I set up tunnelling in PuTTY: Connection -> SSH -> Tunnels
Source port: 5554
Destination: localhost:5554
Type: Local/Auto
Source port: 5555
Destination: localhost:5555
Type: Local/Auto
(Connect and keep PuTTY open, to maintain the tunnel.)
Now I fired up the emulator on the remote machine and made sure that ADB is not running there.
I restarted ADB on the development machine (adb kill-server, then adb start-server).
adb devices and the remote emulator showed up as emulator-5554 device. I could now deploy and run my app straight from Eclipse/ADT, where the emulator showed up under Virtual Devices as if it was a local emulator.

I found an easy way to do this if your two machines are in the same private network and therefore do not need to use SSH encryption (which is the common case). This may help as an SSH tunnel can be quite long and difficult to install. For example, installing an SSH daemon under Cygwin / Windows for the first time may lead to give up (well, I gave up).
Under Windows, what follows requires having Cygwin installed with the package httptunnel. This must work under Linux / httptunnel as well but I didn't try.
Run the emulator on one of the machines (let's say its host name is HostEmulator)
Start Eclipse on the other machine (let's call it HostEclipse)
Open a Cygwin terminal on each machine, and then,
On HostEmulator, enter the following cygwin commands:
hts -F localhost:5554 10000
hts -F localhost:5555 10001
hts means Http Tunnel Server.
These two commands create two half-bridge that listen to the ports 10001 and 10001 and that redirect the I/O of these ports to the local ports 5554 and 5555, which are the ports used by the emulator (actually, the first lauched emulator - if you are several of them running they will use higher port numbers as seen in other replies of this page).
On HostEclipse, enter these ones:
htc -F 5554 HostEmulator:10000
htc -F 5555 HostEmulator:10001
htc means Http Tunnel Client.
These commands create the missing half-bridges. They listen to the local ports 5554 and 5555 and redirects the I/O of these ports to the half-bridges we have created on HostEmulator just before.
Then, still on HostEclipse, enter these three commands:
adb kill-server
adb start-server
adb devices
This restarts adb as it doesn't detect the remote emulator otherwise. It must be doing some scanning at startup. And then it lists the devices (the available emulators) just for checking.
And there you go.
You can work with your remote emulator as if it was local.
You have to keep the Cygwin terminals open on both machine otherwise you would kill the half bridges you created.
I used the port 10000 and 10001 for the machine/machine exchanges here, but of course you can use other ports as long as they are not already in use.

None of the proposed solutions worked for me.
I've started from Emirikol's solution and refined it, as with the new Android API > 21 the emulator was appearing offline and I had to go to Genymotion settings and leave Android SDK path empty.
And from command line:
netsh interface portproxy add v4tov4 listenport=5555 connectport=5555 connectaddress=<emulatorIP>
netsh interface portproxy add v4tov4 listenport=5554 connectport=5554 connectaddress=<emulatorIP>
source:http://www.sarpex.co.uk/index.php/2016/10/02/connect-genymotion-emulator-remotely/
Disclaimer, I'm the author.

When you run adb, it starts a server copy of itself if one isn't already running.
You can start that copy yourself on the machine with the device and since sdk 4.3 you can give it the -a option to tell that server to listen for remote machines. Do that with the following command which doesn't exit:
adb -a -P 5037 server nodaemon
On the machine you want to use the device from, set ADB_SERVER_SOCKET to tcp:xxxx:5037 in an environment variable (or give the same value to each adb invocation with the -L option), where xxxx is the IP address or hostname of the machine with the devices, and 5037 matches the port you gave the in the command above.
We use this to give access to about 100 emulators spread over 3 machines to a machine running end to end tests in parallel, and to developers wanting to share real devices remotely.
You can forward ports to and from the emulator with adb forward and adb reverse, and they'll appear on the machine with the devices (not the machine you're running 'adb forward' from).

My solution for windows + AndroVM (which requires a host-only adapter) when my ssh service failed to start. so it doesn't require any additional software.
adb connect <Andro VM IP>
adp tcpip 555
On cmd prompt run as admin:
netsh interface portproxy add v4tov4 listenport=5555 listenaddress=<host ip> connectport=5555 connectaddress=<Andro VM IP>
open TCP port 5555 in windows firewall.
Then, from the second PC run:
adb connect <host ip>

This post contains many answers but step by step instructions are missing.
So this answer will explain how to connect 2 computers to run projects of one computer on the emulators of another computer.
Requirements before going further:
Firewall should be off in both the PCs.
Both PCs must be connected in the same network.
Notes:
Computer running Android Studio is mentioned as "PC_AS"
Computer running Emulator is mentioned as "PC_EM"
Step 1:
On the computer running Android Studio, open a terminal window and run following command.
ssh -NL 5554:localhost:5554 -L 5555:localhost:5555 dhaval#192.168.0.104
Above command will forward 5554 and 5555 ports of PC_AS to the same ports on PC_EM. So the emulators running on PC_EM can be detected on the PC_AS.
dhaval#192.168.0.104 is the address of the PC_EM. Format of the address is username#local_ip_address
Once you run above command, the terminal window will not show anything if the command is executed successfully. It will look like nothing is going on but the process is running there.
| 💡 Note: Do not close this terminal until you want to stop remote debugging.
Step 2:
Now open another terminal window on PC_AS and run following commands one by one.
killall adb;adb devices
This command will stop the adb and stop the server.
adb start-server
This command will start the adb server.
adb devices
This command will list down all the connected adb devices.
Once you run above commands, you will see that emulators of PC_EM are now detected in the PC_AS. Now you can run the projects on those emulators and debug remotely.
| 💡 Note: While doing the above process, emulators can show a dialog to trust the incoming request.

Android emulators by default listens on local port 5555, so one way to connect to a remote emulator is by using a port forwarding tool to forward all LAN packets to local 5555 port.
One such excellent tool is Trivial Port Forward
Here is the command:
trivial_portforward.exe 1234 127.0.0.1 5555
Here 1234 is the port number where the development computer will connect. 127.0.0.1 is loopback address and 5555 is the emulator’s port.
For more detailed example, see my blog post.

This is how I made it work from host macOS with emulator to macOS client.
A: One line command
On host of emulator
socat tcp-l:5560 tcp:localhost:5559
On client
adb connect <IP>:5560
B: With a tunnel
on host with Emulator
host$ adb kill-server
host$ adb -a nodaemon server
on client with Android Studio
client$ adb kill-server
client$ ssh -L 5037:localhost:5037 <host-IP>
open second shell on client with Android Studio
client$ adb kill-server # I observe first it kills client adb
client$ adb kill-server # then it kills server adb, do it maybe once more
client$ adb devices # show devices on server now
Now I see host emulator in Android Studio as well

I don't have a second machine with the SDK to hand, but I note that the emulator's listen ports (default 5554, 5555) are listening on 0.0.0.0, i.e. reachable from remote machines, and that adb --help shows a connect <host>:<port> command. I assume that would make it show up in adb devices so adb commands work on it. For Eclipse, try "Run / Run Configurations..." and set the Target to Manual. That gives you a "device chooser" which I'm guessing would include a remote emulator if adb is connected to it. Worth a try.
