I'm debuging an android application using my android smartphone (Sony Experia) and I need to connect to the computer's local host through the android app I'm developing. I tried several methods (USB tethering, Wifi hotspot) but I couldn't achieve it. Please support me with a solution. I know that simply 10.0.2.2 is working well on the android AVD but I've no idea about real devices.
I'm using Microsoft Internet Information Services (IIS) as my server and the web application is also running well. I don't know whether the firewall is blocking the port or not.
This should work:
Unplug all the network cables on the computer and turn off your wifi.
Turn off the wifi on your Xperia.
Connect your Xperia to your computer via USB Turn on "USB Tethering" in the android menu. (Under networks-> more...-> Tethering and portable hotspot")
Get the IP of your computer that has been assigned by the USB
tether cable. (open command prompt and type "ipconfig" then look
for the IP that the USB network adapter has assigned, It is Under 'Ethernet Adapter Local Area Connection' title. The Value for the IPv4 address is the One you need.)
Open a browser on the PC using the IP address found instead of
localhost to test. i.e.
http://192.168.1.1/myWebSite
Open a browser on the android and it should work.
If it is working on your PC but not in your device, You have to allow your http through firewall.
Follow How to enable sharing of web site on localhost? to do it.
Situation: on PC installed server, and available address with this site: http://localhost
And installed Connectify Hotspot to share internet via wi-fi.
Also, I have android-device from which I need visit localhost on my PC. Via wi-fi is not principal.
How I can do this? I have read a lot of instructions, but they are for AVD (through 10.0.2.2), that I could do, but not with real device.
I made it.
Disable firewall while you testing connection.
Define your wi-fi IP-address by ipconfig.
On local server you need to create folder with this IP-address and put in this folder site or something, you want to open through wi-fi on mobile.
example: 192.168.77.1/www/index.php
Restart your server. After this you will be able to access to your site in PC-browser by your wi-fi IP-address. If not - restart server another once, or something going wrong :)
Turn on mobile wi-fi and in browser try to access to wi-fi IP-address.
Profit.
localhost on the device refers to the device itself, not to your computer. Get your computers IP address (ifconfig on linux or mac systems) and use this instead of localhost.
I have built an Android application using the emulator to test. It connects to localhost to get and send data which works well. Now I want to try that application on my mobile device. I have read that I have to:
connect my computer to my router network
connect my mobile to my router network
go to the code and replace the 10.0.2.2 with the IP of my computer
Am I right? If so, is that computer's IP the IP that connects my computer to internet?
If you are developing in Eclipse, all you have to do is:
Connect your device to your computer with a USB cable
Right click on the root of your app
Select "Run As" > Android Application
If your device is connected, it should automatically run
Note sometimes you have to select whether you run on your connected device or on your emulator, but a window will display your options and your just select one.
Simple as that.
You are correct, when you simply connect to your local router you can get to your localhost by changing the configuration to point to: "http://10.0.2.2:8080"
I found the other ways to be very tedious

I am trying to deploy and test my application on an android device which is then connected to my laptop with a usb-cable. Now, how can I target a webapp deployed on my laptop ?
knowing that my wifi is down and that I don't have the right to change router configuration to do some IP port forwarding tricks (in case you would like to suggest me to use the mobile network e.g 3G, go on internet and get back in via our router external IP address ==> which is also a little bit heavy given what we want to do here)
According to the android documentation, "the emulator" can use the ip address 10.0.2.2 to access the hosting computer but there is nothing for devices...
thanks in advance guys,
I have an android device (Samsung galaxy tab) connected to my PC via USB .
I want to use WebServices and run a web page which is located on my local xampp server of my PC on my android device .
I can achieve it if I have both , my PC and android device , connected on the same wireless network .
However is it possible to access the localhost page without any wireless connection , using only USB connection .
(PS : This same scenario works when I run the app on an emulator and use the ip 10.0.2.2 to access the localhost on my PC)
Google posted a solution for this kind of problem here.
The steps:
Connect your Android device and your development machine with USB debugging enabled
Open Chrome in your development machine, open new tab, right click in the new browser tab, click inspect
Click the three dots icon on right top side , -> More Tools, Remote Devices.
Look at bottom of the screen, make sure your device name is appeared on the list with Green colored dot.
Look below at the settings part, check the Port forwarding mark
Add rule. Example, if your python web server is running on your machine localhost:5000 and you want to access it from your device port 3333, you type 3333 on the left part, and type localhost:5000, and click add rule.
Voila, now you can access your web server from your device. Try open new browser tab, and visit http://localhost:3333 from your device
I finally solved this problem. I used Samsung Galaxy S with Froyo. The "port" below is the same port what you use for the emulator (10.0.2.2:port).
What I did:
first connect your real device with the USB cable (make sure you can upload the app on your device)
get the IP address from the device you connect, which starts with 192.168.x.x:port
open the "Network and Sharing Center"
click on the "Local Area Connection" from the device and choose "Details"
copy the "IPv4 address" to your app and replace it like: http://192.168.x.x:port/test.php
upload your app (again) to your real device
go to properties and turn "USB tethering" on
run your application on the device
It should now work.
I've read numerous forums and tried play apps but not found a solution until now.
My scenario I believe is similar to yours, but I will clarify to help others. I have a locally hosted website and web services to be used by my android application. I need to have this working on the road for demonstration with only my laptop and no network connection.
Note: Using my iPhone as a wifi hotspot and connecting both my pc and my android device worked, but the iPhone 4S connection is slow and dropped out regularly.
My solution is as follows:
Unplug network cables on PC and turn off wifi.
Turn off wifi on android device
Connect android to pc via USB
Turn on "USB Tethering" in the android menu. (Under networks->more...->Tethering and portable hotspot")
Get the IP of your computer that has been assigned by the USB tether cable. (open command prompt and type "ipconfig" then look for the IP that the USB network adapter has assigned)
Open a browser on the PC using the IP address found instead of localhost to test. i.e. http://192.168.1.1/myWebSite
Open a browser on the android and test it works
I did this on a windows computer and it worked perfectly!
Turn on USB Tethering in your mobile.
Type ipconfig in the command prompt in your computer and find the ipv4 for "ethernet adapter local area connection x" (mostly the first one)
Now go to your mobile browser, type that ipv4 with the port number of your web application. eg:- 192.168.40.142:1342
It worked with those simple steps!
Here is a piece of my Android app's code:
This app is able to communicate with a HTTP get-post model between a servlet running on a server and an Android device plugged in USB-Debuggable mode (because the app was in developing progress).
I also can run the app over Wi-Fi when the server, Tomcat Apache 7, running on (when the app development was finished).
To get the IP address of yours
Go to Command Prompt
Type ipconfig
Hit enter
In the list, IPv4 Address is your IP.
Make sure you have adb installed on the computer, USB debugging enabled on the phone, and the phone has allowed access to the computer. Plug the phone into the computer via USB cable, and make sure it's visible (it should show up in the Bash command adb devices.
In your computer's Chrome browser, open chrome://inspect/#devices, click the "Port forwarding" button, check "Enable port forwarding", and add the port on the computer that you want to be accessible from the phone (detailed instructions here). You'll need to keep open the tab running chrome://inspect/#devices.
In your phone's browser, navigate to localhost:[port_number], and it should display whatever is running on the computer.
This works on Windows and Ubuntu Linux, and should work on Mac as well.
How to Easily access LocalHost in Actual Android Device -> Connect your pc with the android device via USB
Go to Chrome inspection click 'f12' or Control+Shift+C
Chrome Inspection tool
Check the bottom of the chrome inspection tool.
Now go to settings in Remote Device Tab.
Remote Devices Tab
check on "Discover USB Device" option as well as check on "Port Forwarding" option.
Now Click on Add Rules, Enter Any Device Port e.g(4880) and in Local Address Enter the Actual Address of the local host in my case e.g (127.0.0.1:480)
After Adding the Rule go to your android studio -> inside your code URL(http://127.0.0.1:4880). Remember to change the port from 480 -> 4880.
Go to Remote Device Tab in Chrome and Click on your connected Device. Add New URL(127.0.0.1:4880)
Inspect the Android Device Chrome Browser
Check your Actual Device Chrome Browser and start Debugging the code on Actual Android device.
Check for the USB connection type options. You should have one called "Internet pass through". That will let your phone use the same connection as your PC.
I very much liked John's answer, but I'd like to give it with some changes to those that want to test some client//server configuration by running a client TCP on the USB connected Mobile and a server on the local PC.
First it's quite obvious that the 10.0.2.2 won't work because this is a REAL hardware mobile and not a simulator.
So Follow John's instructions:
Unplug all network cables on PC and turn off wifi.
Turn off wifi on the android device
Connect android device to pc via USB
Turn on the "USB Tethering" (USB Modem/ USB Cellular Modem / USB שימוש כמודם סלולרי) in the android menu. (Under networks->more...->Tethering and portable hotspot")
This USB connection will act as a DHCP server for you single PC connection, so it'll assign your PC a dedicated (dynamic) IP in its local USB network. Now all you have to do is tell the client application this IP and port.
Get the IP of your PC (that has been assigned by the USB tether cable.)
(open command prompt and type "ipconfig" then look for
the IP that the USB network adapter has assigned, in Linux its ifconfig or Ubuntu's "Connection information" etc..)
Tell the application to connect to that IP (i.e. 192.168.42.87) with something like (Java - client side):
String serverIP = "192.168.42.87";
int serverPort = 5544;
InetAddress serverAddress = InetAddress.getByName(serverIP);
Socket socket = new Socket(serverAddress, serverPort);
...
Enjoy..
Hello you can access your xampp localhost by
Control panel -->
windows defender firewall -->
Advance setting (on left side) --> Inbound Rules --> New Rule --> Port --> in specific local port write your Apache ports --> next --> next
then you can access your localhost by using local PC IP address:
Zsivics Sanel's answer above work fine for USB Debugging but if you want to access your localhost on device for Wifi ADB you can use command
adb reverse tcp:port tcp:port
and use the link http://localhost:port/ on your android to access the http://localhost:port/ of your pc.
This works for USB Debugging as well :)
The detailed answer with explaination is here.
Connecting android phone via USB cable and accessing http server on the Computer.
Firewall - switch it off, once everything works you can add a rule
under Inbound rules, enable Apache HTTP Server (UDP and TCP) (or whatever HTTP server you're using) Warning - if you switch off the firewall, your computer becomes vulnerable to internet attacks. So switch off internet and disconnect from network first. You don't need to be on the Internet for this to work, as you're connecting two devices on local network.
Plug in the USB cable. If networking window pops up, select Home Network. If it doesn't pop up it's probably set to Public (which won't work), so go to: Control Panel\Network and Internet\Network and Sharing Center (in win7) and set it to Home Network there. It might give you a next screen after you press it to share Pictures, Music... just click cancel on it. On the main screen Home Network will still be active.
You need the Computer's IP, localhost or other aliases don't work. To get the IP of your machine, start the Windows command line shell (press Windows Key + R and type cmd), the black command prompt window should pop up, type: "ipconfig" and hit enter. Now look for
IPv4 Address. . . . . . . . . . . : 192.168.###.###
That's the IP that your phone assigned to your computer
Now you should be done, in the phone's browser, try accessing a test html file from your computer's server it should display fine.
Now that everything is working you'll probably want to enable the firewall and Internet access on your computer. Now try accessing your http server again. It probably won't work. Depending on your setup you might get a popup asking you to add a rule to allow it, but if you don't, just add it yourself. Start the windows firewall and go to Inbound Rules (because it's a server) and add New Rule. Select "Program". Locate the exe of your http server, and in the next screen make sure Allow is selected. Try connecting again, and now it should work. If not it's probably because you selected wrong exe. You can even go more advanced to restrict outside usage (because now everyone on the internet can access it if they have your Internet IP address) To restrict access you can right-click on the new rule you've just created, click Properties, and go to Scope tab and change things there accordingly.
Note for Android developers, now in your android code, you have to use "http://", otherwise it won't work. For example: MyAsyncTask.execute("http://192.168.123.123/test.html")
Part II -- Setting IP to fixed/static.
Now that things work, every time you unplug the cable and plug it back in, your IP will change. And if you are using it somewhere like inside a code, you'll have to update it every time! Solution I've come up with is to set the IP to static.
Having the phone connected and tethered, go back to Network and Sharing Center and click on the Local Area connection "Connections:"
On the next screen select Properties, then highlight IP 4 and press properties there and click "Use the following IP address"
Put Default Gateway and Subnet Mask exactly as it was in the ipconfig, and for the IP Address, only change the last 3 digits to anything from 1 to 255
That IP will be your new fixed/static IP and it will remain the same next time you plug the phone.
Problem I faced maybe it will help some one, I was working long time where my pc and android device connected to the same WiFi network and the android device connected via the IPV4 address of the pc with opened port 8080 trought the fire wall.
ONE DAY :
I installed Genymotion emulator in order to debug UI on different screens.
THANKS to Genymotion/Virtualbox network configurations it ruined my WiFi adapter.
The fix was to reconfigure IPV4/TCP settings on the WiFi netwrok adapter :
