following http://www.webrtc.org/native-code/android, the WebRTCDemo apk I built runs well on my android device and can start video calls with Chrome. the issue is 1) the apk failed to establish connections with peers when in different LANs, 2) but two Chromes can succeed to start p2p calls.
after checking the log I found the apk gives wrong candidate transport addresses. my private address is 10.10.10.108 and the public address is 112.10.45.196, the apk will send the following transport addresses to room server:
10.0.2.15
10.10.10.108
10.236.188.19
..ipv6..
so it is odd that where the apk learned these tow addresses:
10.0.2.15
10.236.188.19
after sniffing traffic using WireShark, I did not found any clue, the TURN/STURN server respond with correct values.
so anyone knows why?

I'm new to web-crawlers, trying to crawl ridership data of metro from the cellphone maps app(www.amap.com) with Fiddler, but I got this HTTP connect method, which is not viewable. There are icons of locks next to the URL and in 'Response' it says this:
'Encrypted HTTPS traffic flows through this CONNECT tunnel. HTTPS Decryption is enabled in Fiddler, so decrypted sessions running in this tunnel will be shown in the Web Sessions list.'
I found a solution suggesting that customizing rules in fiddler may help, so I followed and added this to its script:
if (oSession.oRequest[‘User- Agent’].IndexOf("Android") > -1 && oSession.HTTPMethodIs("connect")) {
oSession.oResponse.headers["Connection"]="Keep-Alive";
}
The changes to Fiddler Script
But of course, it didn't work, I've tried both iPhone and android and changed the header in the script respectively, none of them helped.
So is this app and HTTP connect method crawlable? The data is constructively helpful to my research, instead, it is not provided in website 'amap', so it has to be done through a cellphone.
If you have HTTPS decryption enabled in Fiddler but you see (mostly) only CONNECT requests this means that the apps on the device try to open a connection but do not trust the Fiddler root certificate.
If you try to use the apps on-device you will notice that there is currently no working network connection available (requests just don't work as the apps don't accept the server certificate created by Fiddler).
On Android devices since Andorid 6 you need root permissions to instal the Fiddler rot certificate or alternatively if you want to monitor a single app you can try to modify and re-sign the app. All details are described in this question and answer:
Some androids apps won't connect through fiddler
I have a Rails application running in my laptop and an android application on phone. I want to call apis of rails application where routes are namespace with sub-domain.
My api look like below:
http://api.localhost:3000/login (With sub-domain)
When I replace localhost with ip address. It will work in browser but in android application it gives me Android java.net.SocketTimeoutException: failed to connect. But when I namespace without sub-domain it works.
http://192.168.1.101:3000/api/login (Works fine)
What is the correct URI with sub-domain ?
http://api.192.168.101:3000/login (Gives above error)
The easiest way to solve the problem is if you have a domain registered. You can add a DNS entry for hostname api.192.168.101.
If not, you have few options.
Setup your wireless router to resolve the hostname api.192.168.101 to 192.168.1.101. I am assuming, your phone's DNS server is your wireless router. If your wireless router does not support adding local DNS entries checkout the next option.
You have to add the entries to "/etc/hosts" file of your Android phone. It is easy for rooted phones
I suggest you consider buying a domain from a good vendor who provides you a decent DNS management console.
I am trying to make a connection from my Android to my local machine on a wifi network. My machines wifi ip address is 10.27.27.172 and I am running my node.js server on port 7890. I can use my phones chrome browser and browse to my server and access some endpoints which return json. My problem comes when I try and use spring-android rest template. I have given INTERNET permissions to my android application but I still get a ECONNREFUSED error. Is this an android port issue? Is the firewall blocking my request. If so why can I browse to the server but not use the REST client to get the information?
I found the answer on this stackoverflow. You need to make sure you retype the I guess the eclipse editor sometimes adds in invisible characters or something. Anyways it is working now.
I am experimenting with the new VPNService API with the sample project "ToyVPN". I have not modified the source code and it compiles smoothly, but I cannot seem to get it to connect to my VPN server on ec2. It times out with the error "Got java.lang.IllegalStateException: Timed out". From the server's perspective, no packets are being received from the phone.
I am entering in the ip address of the server, 1723, and my password for server address, server port, and shared secret respectively.
I am able to connect to my vpn server using the default ubuntu vpn manager over pap authentication using the same password.
Can someone offer insights on what is going on and how I can make ToyVPN connect to my server?
What about sample server implementation from "ToyVPN" project? Why don't you use it?
It is easy to set in Linux, all steps and limitations are described in ToyVpnServer.cpp file. Certainly at first you should compile it. I compile it using GCC package:
gcc ToyVpnServer.cpp
Program file named "a.out" will be created in the same directory.
Then just run it from command line with the parameters that described in ToyVpnServer.cpp.
It is strange, that you don't see any packets on the your VPN server side. I tried to connect to my VPN server through ToyVpn just to see what will happen. Connection was failed, but there were messages in server logs, that the packets are received, but its size is too small.
Hope this will help.
I am working in android chat application.
I used SmartFox server. I am using 10.0.2.2 as server IP address and 9933 as Port.
Whenever i run this application using emulator then works fine but when i run this application in my real device then connection does not performed correctly. I think this is unable to find out IP 10.0.2.2.
I changed this IP address to 192.168.1.9 which is IP address of my system in LAN on which SmartFox server is installed.
Please suggest me what mistake i have done.
Thank you in advance.
I resolved my problem myself. I created one entry in confi/server.xml file of server.
like this:-
<serverSettings>
<socketAddresses>
<socket address="192.168.1.9" port="22" type="TCP"/>
<socket address="192.168.1.9" port="22" type="UDP"/>
</serverSettings>
</socketAddresses>
or you may add this entry using admin module of Smartfox server. This task can be done using Server configuration part.
