When i run my project on Emulator than localhost servery is working but when run on real Android phone than localhost server not found. So how can i access my localhost server from my real Android Device. I use XAMP server.
You cannot access localhost from your mobile device because the server is limited to your system only. In order to test the application you have to run the application on emulator so that it could find the server. Although there is a way...if you are creating a whole server that is backend and you have a network to which your mobile and system is connected then you can set your server to listen to a port on that network. I used NodeJs to accomplish that. You can search some tutorials for using NodeJs through which you can access you xampp server. You can also try AdonisJs which is a framework for NodeJs for a better approach. But keep in mind that you need a common network through which your system and your mobile device is connected. It is a bit complicated method but yes that can work. Accessing localhost directly from system to your mobile device is not possible..if you want to avoid learning NodeJs then you'll have to keep using emulator for the testing but learning something new is always amazing. So i would suggest you to learn NodeJs . Anyways you can avoid all the trouble and keep testing your application using your emulator. I hope this answer will help you :)
You should have told which ip you used running on emulator.
Your client on the android device should use the ip of the computer where your server is running on.
Android device and server computer in same WLAN.
If your computer and mobile are connected through same internet line then you can use ip of your computer instead of localhost can do the work.
You cannot access the local host server from a different node eventhough both nodes are connected to same network only way is that change the ip configuration of server to 0.0.0.0: so that you can access the server from any node just by typing the ip of the server followed by port no...

I want to connect to a server on my local network (10.134.0.178:80). The ip address of my machine is 10.134.3.12 and the ip address of the emulator Wi-Fi is 192.168.232.2.
Now I found out that you have to use 10.0.2.2 to connect to a server on your local machine. But the server isn't running on my local machine - instead it is a separate instace on my LAN.
My local machine can reach and ping the server without problems. The emulator not, but the emulator has internet access. So I can access e.g. www.google.com.
How can I connect the emulator with the server? The shown redirection rules only apply on port level. So how is this meant to be used? Other solutions only talk about a local server. Only one is talking about a similar case, but this is not working for me (no connection)
netsh interface portproxy add v4tov4 listenport=80 connectport=80 connectaddress=10.134.0.178
Additionally, I have to switch server instances (different ips/ports/addresses). So how can I use the Android Emulator in this case? To which address should the webservice calls be made? 10.0.2.2 or 10.134.0.178?
Hmmm, well, your Android app should connect to the server's address/port as it appears to the host machine running the Android emulator. I have a web server on my LAN and my emulator can access it directly. Start with pointing Chrome in your emulator at a web server on your LAN (assuming you have one on there somewhere) - if the server is on 10.134.0.178:80 then just type 10.134.0.178 in to your Chrome address bar. If that's not working then you need to look and see what's stopping it - any redirection rules getting in the way?
Don't know what the reason was, but the most plausible one is, that the server had a temporal issue. Now I can connect to my server without further changes!
One thing what still didn't work for me was ping, but it is listed under Local networking limitations:
Depending on the environment, the emulator might not be able to support other protocols (such as ICMP, used for "ping"). Currently, the emulator does not support IGMP or multicast.
I'm developing an android app that connect with a restful web service which is on my tomcat local server.
The app works well on the emulator, however, it doesn't work on my real mobile.
I use the IP from ipconfig, and both my laptop and my phone connected to the same Wi-Fi.
I tried to call the web service from the mobile browser but still, it doesn't see my localhost :(!
it shows me :
This site cannot be reached.
I searched a lot and all the solutions say that I have to connect both to the same Wi-Fi network and to use the IP from ipconfig command, which I did!
How can I fix this?
PS: I'm using 9090 as my port number, I don't know if that a reason?
Thank you.
I am trying to implement an Android application in Windows 7 using Eclipse. I am trying to connect the Android simulator to the local test server in my company, but for some reason, it cannot connect to the test server.
If there is any settings or configurations for this, please let me know.
I have tried to do the same from a MAC machine using iPhone emulator and I am facing the same problem. How would this emulator connect to the local servers in my company as currently it all goes to live servers? What configurations are required to be done on the simulators, and how?
If I try to connect to the test server from normal Windows machine browser, I am able to successfully connect to it through the web browser; but when I try to do the same from the Android emulator browser, it cannot connect to it.
The emulator points to the live network and not the local network in my company. This is strange and I know that I need to do some settings for it, but I am not sure where these settings are done and how.
If accessing local computer:
http://localhost:8080/MyLocalServer.html // URL to use in computer browser
http://10.0.2.2:8080/MyLocalServere.html // URL to use in emulator browser
Also try using a local IP to connect to any local servers. Do not use host names.
Dont:
http://mylocalserver.org/
Do:
http://192.168.1.125:portnumber
You have to set up IP-based hosts instead of name-based.
Emulator its - VM. This use virtual network connection. I think you need before chech this connection (this connection may bee stay as NAT, Breedge, Native IP adress, Proxy).
Since you do not work iPhone emulator, most likely you, IP adress virtual network connectionб which uses Emulator, does not match the address area of the local network, and routing occurs
This may help you...
Taken from the android docs:
If you need to refer to your host computer's localhost, such as when you want the emulator client to contact a server running on the same host, use the alias 10.0.2.2 to refer to the host computer's loopback interface. From the emulator's perspective, localhost (127.0.0.1) refers to its own loopback interface.

I have a Tomcat server running on Localhost. My app can access it in the emulator using 10.0.0.2:8080. But when I connect a device it can't access the server.
I've seen some similar questions but couldn't get this working. can someone give me the steps on what to do?
we use 10.0.2.2:8081 because 127.0.0.1 is reserved for the emulator, however, when you need to try the application through a real device you need to change the URL to your PC IP
go to CMD and run ipconfig, look for IPv4 address, this IP you will use it..
add it to the URL for example: http://192.somethin.somthin.somthing:8081/the-location.php
P.S: you should set your firewall off and turn off any antivirus
The device may not be on the same network as the Tomcat server. Does your network provide VPN access? If so, try installing an Android VPN client (Junos Pulse is a good free one). Connect your device to VPN and try again.
10.0.0.2 looks like an internal address. The emulator is likely able to connect because the machine on which it is running is connected to the network. The actual device needs a direct connection as well. VPN should solve that.
I need to send an image file from the mobile to the server(where the server will save it to the hard disk). I have wrote both the android mobile part and the server side. I need to test the code before deploying to the server. Will the code work if I connect the mobile to the WI-Fi network through which I can have a LAN connection to the system? Is there any way I can test the code with out using a WI-Fi connection(ie Connecting phone to the system via the usb cable and then forming a LAN or something)? Please voice your valuable opinion in these stuff.
When I was testing my server-side I didn't find any other way rather than connecting via wifi, this way it was working just fine (in your code you need to use ipv4, not localhost, just as reminder). I'm not good with network stuff, but I don't think it's possible using usb to create some kind of LAN.
