Good day.I am trying to connect my android application to xamp. Basically I have an application that uses xamp, it works on an emulator but not on the actual device.After hours of searching, I found solutions to use tethering on usb and wifi. With tethering I get the error "adb problem, unable to communicate with device..please kill add".With wifi, it does not access my localhost.I know that someone might say this is a broad question.What I am asking is, how can I make my device access my xamp localhost?
I just mentioned the above to show what I tried and could not succeed.
If your android device and the device running XAMPP, are both on the same network, you could just use the private IP address of the machine running XAMPP, but if they're not on the same network, then you are gonna need to do some port forwarding and maybe get a static IP address.

I've setup a racoon server on my linux router. It was working ok with my xperiaz (C6603) road warrior. However after I applied the latest update to android 4.4.2 (firmware 10.5.A.0.230) it stopped working correctly. I have ping from the phone to each ip (local ip or internet) but when I use FQDN it can't be resolved. I can ping the phone from within my local network too. VPN is IPSec Xauth RSA. Checking with adb DNS server is correctly set:
getprop net.dns1
192.168.6.1
I also tried pushing the same ip as dns2 but no change. I also noticed that after closing the connection to the vpn server net.dns1 remains 192.168.6.1 however the phone is able to correctly resolve addresses. In few minutes it gets changed back to my 3g provider setting.
I tried to redirect all traffic through the tunnel via the advanced vpn setting (Forwarding routes = 0.0.0.0/0) and tried to set DNS statically via the same settings (DNS servers = 192.168.6.1). Even setting the DNS server to my provider's DNS addres didn't work which makes me think the problem is with the android itself.
DNS server is working as far as I can tell:
$ dig #192.168.6.1 dir.bg +short
194.145.63.12
Forwarding is enabled on my router so shouldn't be the problem. I've read about a bug in android but it's in android 2.x and seems to impact wifi connections.
Have you seen similar problems and as I'm not an expert with android and adb, can you tell me what commands are available in adb/shell to trace the problem? Phone is not rooted and it's not possible for the moment to root it.
UPDATE:
the tunnel is working ok when I connect via wifi hotspot. The problem appears to show only via my 3g carrier. Any ideas how to work around this?
After updating to 4.4.4 I still got the same problem. Further testing revealed that the problem is more likely to be in the Android rather than my 3g carrier. Over wifi the VPN worked flawlessly after using wifi tethering from another phone via the same provider it worked ok again so my 3g carrier isn't blocking anything.
Yesterday I finally rooted my phone and installed SDFix to restore full access to my SD card. Now VPN is working ok again even via 3g. I hope someone can confirm/reject that solution as I see no relation between vpn and sd card at all. However I experienced initially the problem with my update to 4.4.2 where Sony started to follow Google's policy about storage access.
i have in my laptop in virtualbox a UbuntuServer with a webservice at ip: 192.168.1.46, and webservice, ServerName is api.webservice, so from my laptop if i try in the browser api.webservice it works well!.
Now the problem, from the android device not work, the webservice,laptop and device are connect in the same network, from the device if i try in the browser 192.168.1.46, it tell me it works, but if i try api.webservice not work..
there are any solution?
Probably this is a problem with name resolution.
Your laptap (Windows?) is able to resolve "api.webservice", but your Android device not.
It highly depends on your infrastructure (WLAN-Router, DHCP-Server) how to solve this problem. You could perhaps provision your WLAN-Router/DHCP-Server to permanently bind api.webservice to the IP address of your Ubuntu box, so Android device can make a NS-lookup.
I suppose your Android app will connect a real Internet server in future. In this case, I wouldn't bother connecting the webservice by IP-address for test purposes.
When your app is published and used outside your local network, name resolution will work when connecting to a internet server registered in "official" DNS.
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 develop app which contains a client and a server side, so I need to test work between them. I have a real android device and I want android device to connects to emulator. I'm working at work sometimes(if I have free time of course) and at home. I have the WiFi router at home and I can connect to the real device by emulator(TCP listener running on the real device), but not vise versa(I don't know which exactly IP to use). But at work I have only hot-spot WiFi point without router. My android device connects to it fine. Even more ADB can connect to the device when adbWireless running on it. But it doesn't work, I can't connect to tcp listener in any cases. The difference between home and work is existence of WiFi router. Are there any solutions? If not why Android debug bridge(ADB) can connect to adbWireless? Thanks.
I solved the problem. I run tethering on my real device and run the server on it. Then I use a program Connection state viewer there is a link: https://play.google.com/store/apps/details?id=ru.nolesh.android.connectionstateviewer It helps me to find IP address. After that I start the emulator and the client side on it. So I connect to my server by given IP.
In my house I can connect my android device to the service in my laptop as they are both on the same network. My question is, supossing I'm going to a bar and I can connect my laptop to the wifi but not the cellphone, how can I make the cellphone reach the web service on the laptop?
I tried to create an add hoc network and connectify.me but neither worked. With Connectify.me I was able to connect to the laptop from the phone but the phone could reach the web service (maybe a filter for the free version?)
Any advice?
I've already checked this: Connect an Android Device To a Web Service on Local Host and it's not the same as my problem.
Thanks in advance! Guillermo.
I haven't tried Connectify, but Virtual Router worked for me. There are some more instructions here if you need it.

Most likely, you can't. The bar is unlikely to have given you a public IP address, and it unlikely that you will convince the bartender to allow you to modify their firewall to forward a port to your notebook.
