Accessing a forwarded port from Android Emulator

I have a Vagrant box which runs a nodejs server with port 3000 which I have forwarded to my host with vagrant ssh -- -L 3000:localhost:3000. For some reason, using 10.0.2.2:3000 on the Android Emulator does not reach this server. Is there anything else that I have to do to access an already-forwarded ip and port from within an Android Emulator instance?
It does work from my host, but not within Android Emulator.
Thank you!

This turned out to be my application's issue. From nc in adb shell I can access the interface in question.

Running / controlling an emulator on remote server

I use couple of Android apps on daily bases, and it's very time consuming.
I want to somehow automatize the process.
The idea is to install some sort of emulator on the server, and program that emulator through some programming language to run the apps on the server when its needed.
I'm a web developer, I work with PHP, nodejs, python,
not really familiar with mobile space.
Is there any solution out there to do what I want?
I search around and found Appium but I'm not sure if it would do what I want.
Please note these apps don't have a public 'api' for me to use.
Also I only have remote access to server via 'ssh terminal', so solutions with 'GUI' dependency wont work for me.

You can use some emulator, like Bluestacks and then run a script to run apps and then use macro tool to emulate clicks in the games or apps
check this link for the macro tool in bluestacks : https://www.bluestacks.com/blog/bluestacks-exclusives/combo-key-bluestacks-record-replay-action-single-key-en.html
Or you can write a script which uses adb commands to run and control the app.
For example.
to run apps. adb shell am start -n com.android.settings/.Settings
this command will open the settings app in the emulator.
to send touch events you can use : adb shell input touch <x> <Y>
adb shell input keyevent <keycode> to send keycodes

I'm assuming that you want to automate native Android apps.
Short answer: Appium will be good solution for you.
On your remote server you will need:
Android SDK and Simulator
Python 2.7 installed
Appium server/node (install using node.js npm )
With everything installed you will be able to start Appium Nodes on your server and run Appium scripts against them.
I suggest using CI server of choise for automating this process. It should make starting your test trough ssh terminal easier / 100% automated.
I never used Selenium/Appium in python, so I can't really help you with Appium tests code examples, but I'm sure there are a lot of basic tutorials for python.

You must install AppiumServer and android sdk/simulator in the remote server. I am going to show how it can be done in java. Hope you can convert it into javascript code.
Check the ip Address of your remote server using ipconfig
Start your appium server in the remote server
>appium -a "ip address of remote server" -p 4732 --session-override
Start the emulator in the remote server.
Define and initialize DesiredCapabilities and AppiumDriver in your code like following.
AppiumDriver<MobileElement> driver;
DesiredCapabilities caps= new DesiredCapabilities();
caps.setCapability(MobileCapabilityType.DEVICE_NAME, "android device");
caps.setCapability(MobileCapabilityType.PLATFORM_NAME, MobilePlatform.ANDROID);
caps.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, 300);
caps.setCapability(MobileCapabilityType.AUTOMATION_NAME, "uiautomator2");
caps.setCapability("appPackage", "enter your appPackage");
caps.setCapability("appActivity", "enter your appActivity");
driver= new AndroidDriver<MobileElement>(new URL("remote server ip address" + ":4732/wd/hub"), caps);
Make sure both device are in the same network. you must get response while pinging to the remote server ip address

Can't access my laptop's localhost through an Android app

So I did a research before posting this and the solutions I found didn't work, more precisely:
-Connecting to my laptop's IPv4 192.168.XXX.XXX - didn't work
-Conecting to 10.0.2.2 (plus the port) - didn't work
I need to test an API i built using Django Rest framework so I can get the json it returns, but i cant access through an Android app i'm building (I'm testing with a real device, not an emulator). Internet permissions are set on Manifest and i can access remote websites normally. Just can't reach my laptop's localhost(they are in the same network)
I'm pretty new to Android and Python and Django as well (used to built Django's Rest Framework API).
EDIT: I use localhost:8000/snippets.json or smth like this to connect on my laptop.
PS: I read something about XAMP server... do I need it in this case?
Thanks in advance

Have you started the server like this?
python manage.py runserver 0.0.0.0:8000
Then, try to connect to 192.168.XXX.XXX:8000

I tried the above, but failed to work in my case. Then with running
python manage.py runserver 0.0.0.0:8000 I also had to add my IP to ALLOWED_HOSTS in settings.py, which solved this issue.
eg.
Add your ip to allowed hosts in settings.py
ALLOWED_HOSTS = ['192.168.XXX.XXX']
Then run the server
python manage.py runserver 0.0.0.0:8000

Others have already given the answer but those solutions didn't work for me when I was running Django server on Ubuntu and was trying to access it from my Mobile app.
Following is what worked for me:
Step 1: Run server to access it from your IP
python manage.py runserver 0.0.0.0:8000
Step 2: Open port in firewall (Missing step in above given answers - Needed for Ubuntu)
$ sudo ufw enable
$ sudo ufw allow 8000

There is any configuration for this tools eclipse or wamp or android sdk to connect my mobile phone to wampserver

here is any configuration for this tools eclipse or wamp or android sdk to connect my mobile phone to wampserver?
i look this exemple in this site blow i just copy and paste the code in eclipse but the problem is how i can import and export data from my phone to database and Conversely ?

If I've understood correctly, you're running a wamp server locally on your computer and you'd like to access that server from your application. The general approach is similar to connecting to any other server, but you'd have to find the right IP-address to connect to. Try this:
First, make sure your server is up and running.
Second, access the server on your computer using one of two addresses:
If you're testing your app on the emulator (AVD), use this: 10.0.2.2, which translates to the localhost-address on your computer.
If you're testing your app on an actual device, you'd have to find your computer's IP-address. On linux, open a terminal and execute the command ifconfig. In windows, I believe it's ipconfig. Use the address listed under wlan0 -> inet addr.
Remember to append the port number your server is running on.
EDIT
Example, given port number is 80:
Emulator: 10.0.2.2:80
Device: 192.168.X.X:80

Can't connect android emulator to look at local sites and services

I'm trying to use an Android emulator to use services running on my local machine. I have a site running under IIS which in my host file looks like this:
127.0.0.1 www.local.company.co.uk
I have several sites running under Apache Tomcat. My host file for Tomcat related sites:
127.0.0.1 internal.localhost.company.com # port:8090
127.0.0.2 external.localhost.company.com # port:8081
127.0.0.3 auth.ws.localhost.company.com # port:8082
127.0.0.8 mysite.localhost.company.com # port:8086
What I have tried so far (in the following steps):
adb pull /etc/hosts
Edit Android host file:
127.0.0.1 localhost
10.0.2.2 myefc.localhost.efinancialcareers.com
adb remount
adb push hosts /etc/hosts
Then I try to visit myefc.localhost.efinancialcareers.com in the browser and am told webpage not found. I’d at least expect it to go to www.local.company.co.uk.
What I would ideally like is to be able to go to any site on my local machine which are specified in the above host file examples.
I am on Windows 7 and using Tomcat 6. The emulator I am using is nexus one.

You need to use the IP address of your server. If you reference localhost from the device it will try to make a connection to itself through the loopback IP address 127.0.0.1.
