Add IMEI and MAC to wlan0 to Genymotion/AndroVM

Is there any way to add IMEI to AndroVM (now Genymotion) or any other Android Emulator. And also I want MAC address for wlan0 port. We already have emulators which contain MAC at lan0 port but not for wlan.
How can we do so?
if someone in your acquaintances has done so please ask them to contribute.
Details:
I am trying to build a cloud based Android App testing center as my pre final year college project for partial fulfillment towards my Bachelor of Technology (Computer Science) degree.
I am wondering how we can get more configurations for Genymotion.
Or if you can provide me with more device configurations and if it is possible to build configurations for genymotion for different devices very quickly.
Secondly, How to add MAC addresses and IMEI number to the builds?
We are trying to emulate a mobile device (non Google nexus) to make a cloud based testing centre.
For this we are trying to use androVM (Genymotion) and we are facing a few problems
What have we done so far
Building the androVm source code in "VBOX86tp-userdebug" mode from the scratch after following the steps given on official Android website.
After building the source code on a virtual ec2 server, typing the emulator command runs but its blank.
And if possible can AndroVm be run in "Fastboot" mode so that we can install it on the device.
We have been working on "building the androVm" from source code and trying to accomplish few tasks like
Running it with the img's available after the building process is complete.
Making it portable ie creating an iso/ova out of all the stuff found in the out directory.
What we have tried till now
Downloading of the AndroVm source code
initializing the repo using repo init
Downloading the source code using repo sync
choosing the lunch menu using lunch
choosing vbox86tp-userdebug
Other menus full-eng didn't work so discontinued
Few errors that came our way
Make errors: they were pretty straightforward so resolved
system.img was not being generated: resolved by making it again
bin/bash jar command error: happened to be the path error resolved by the exporting the path to jar command.
Few Questions
What an OVA file consits of and how can it be created? From what I have seen it contains few VMDK's and few configurations files attached to it,
How to convert the platform specific image files(system.img ramdisk.img userdata.img) into an OVA or ISO file.
If at all we are missing few files to give to the emulator, can you just name them.
Also how to add IMEI number
We already have MAC for eth0/1 port but we want it on wlan port
Now to make things interesting
This is the reply I got from Genymotion Team:
I want my project to cover various configurations but for starters if i can get something like Samsung Galaxy phones and tab or as a
start if I can get Samsung galaxy tab 2.
You can change the screen size and DPI for each virtual device. You
can toggle navigation bar and virtual keyboard. However, we cannot
provide virtual devices that contains proprietary applications like
Samsung.
Now here what we get is the MAC address of eth0/1 port. What if I need wlan MAC.
Unless one of the two network interface have been disabled, there
should be 2 interfaces, 2 IP, and 2 MAC addresses: adb shell ip a. 2:
eth0: mtu 1500 qdisc pfifo_fast
state UP qlen 1000
link/ether 08:00:27:d4:fe:e0 brd ff:ff:ff:ff:ff:ff
inet 192.168.56.101/24 brd 192.168.56.255 scope global eth0
inet6 fe80::a00:27ff:fed4:fee0/64 scope link
valid_lft forever preferred_lft forever 3: eth1: mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 08:00:27:c8:37:e7 brd ff:ff:ff:ff:ff:ff
inet 10.0.3.15/24 brd 10.0.3.255 scope global eth1
inet6 fe80::a00:27ff:fec8:37e7/64 scope link .
Sorry, but we do not provide support for specific ROM. However, I
strongly recommend you to visit the community at:

1. What an OVA file consits of and how can it be created ?From what i have seen it contains few VMDK's and few configurations files
attached to it,
"The entire directory can be distributed as an OVA package, which is a
tar archive file with the OVF directory inside."

2. How to convert the platform specific image files(system.img ramdisk.img userdata.img) into an OVA or ISO file.
If at all we are missing few files to give to the emulator, can you just name them.
Please read the community tutorials
3. Also how to add IMEI number
There is currently no way to add IMEI number. This feature will come
in the near future
4. We already have MAC for eth0 port but we want it on wlan port
There is 2 interfaces: eth0 and eth1. Eth0 is used for Genymotion
application widgets. If this network connection is broken, Genymotion
would not be able to start anymore. Eth1 is used for network current
access (fake WiFi connection). You can change this network
configuration as you want.

It is a common practice for mobile applications to identify the user by IMSI number (associated with the SIM card) or IMEI number (unique ID of the device). Of course, it is also possible on Android:
TelehponyManager manager = (TelehponyManager)getSystemService(TELEPHONY_SERVICE);
String imei = manager.getDeviceId();
String imsi = manager.getSubscriberId();
This code works perfectly fine on a real device, however under emulator IMEI is always all-zero and it’s not configurable. It quickly becomes awkward when debugging a network-enabled application which uses IMEI as a user ID.
Trying to resolve the problem I first looked at the TelephonyManager service, just to find the following snippet:
private IPhoneSubInfo getSubscriberInfo() {
// get it each time because that process crashes a lot
return IPhoneSubInfo.Stub.asInterface(ServiceManager.getService("iphonesubinfo"));
}
Fair comment, isn’t it? It really made my day :)
Anyway, code analysis shows that IMEI/IMSI request goes down through all the telephony layers (see the diagram), eventually getting to the baseband device. In case of emulated system, rild daemon is used together with libreference-ril.so – reference Vendor RIL library which talks to the baseband modem device using plain, old AT commands.
The modem device itself is emulated outside the Android system, as part of qemu (which is the heart of the emulator). Details of the communication between the emulator and the Android system running inside the emulator are interesting on its own (all the communication goes through a virtual serial port, Android system’s qemud daemon is used to (de)multiplex the data). I’ll try to post a brief introduction to the topic soon.
Virtual modem implementation can be found in external/qemu/telephony/android_modem.c. The most important part of the file is this function:
const char* amodem_send( AModem modem, const char* cmd );
This function is called for each received AT command. For each command sDefaultResponses array is searched for a given command and either predefined response is sent, or a command handler is executed. The array itself looks like:
static const struct {
const char* cmd; /* command coming from libreference-ril.so, if first
character is '!', then the rest is a prefix only */
const char* answer; /* default answer, NULL if needs specific handling or
if OK is good enough */
ResponseHandler handler; /* specific handler, ignored if 'answer' is not NULL,
NULL if OK is good enough */
} sDefaultResponses[] =
{
/* ... */
{ "+CIMI", OPERATOR_HOME_MCCMNC "000000000", NULL }, /* request internation subscriber identification number */
{ "+CGSN", "000000000000000", NULL }, /* request model version */
/* ... */
};
Two array rows cited above are responsible for IMSI and IMEI retrieval. As you can see, both values are hardcoded and there is no chance to modify them without recompiling the emulator.
However, an old-school hack comes in handy. The emulator binary is not encrypted nor compressed, so the string literals should be visible inside the emulator binary. In fact they are, and IMEI number can be modified in a few simple steps:
** backup the emulator binary
** open the binary with your favourite hex editor
** search for +CGSN string followed by a null byte, it should be followed by 15 digits of the IMEI number
** edit the number, be careful not to change the number of digits
** save the file, that’s all!
Sure, it’s not a perfectly comfortable solution, yet better than nothing. In the next part I’ll explain how to make IMEI number a configurable option. Enjoy!

how to change port 80 android

I made a webserver on my android device(using Nanohttpd). It's working fine over the port 8080
but I want to make it okay over the port 80,(I want to tape on my browser : http://192.168.x.x instead of http://192.168.x.x:8080/ ) but I'm not able to do it
This is how I call the method that creates the webserver:
httpServer = new NanoHTTPD(80,Environment.getExternalStorageDirectory());
Can someone tell me what service is running by default over the port 80 ?
How can i fix this problem ?

I finally found a way to fix that, for those who have the same problem, here is the solution
I rooted the phone using UnlockRoot
then I installed Port redirector from the play store and I forwarded the traffic from port 80 to port 8080, and now my web server is available from the address: 192.168.x.x
Hope it will help :)

Ports below 1024 are restricted on Unix like systems. You need superuser privileges to bind to these "well-known" ports.
List of these "well-known" ports on wikipedia

Check out line 89 of the server source:
https://github.com/NanoHttpd/nanohttpd/blob/master/core/src/main/java/fi/iki/elonen/NanoHTTPD.java
I don't even see a constructor that type-matches your arguments. That might be part of the problem.

Android gingerbread DHCP 119 setprop not working

I am try to set custom DNS suffix (yahoo.com in my case) using adb command
setprop net.dns.search yahoo.com
I verified it using
getprop net.dns.search
and it returns yahoo.com
However, when I type music in my browser and run tcpdump in the adb, here is what I get.
So, the query is actually "music.yahoo.com", but somehow, the android default browser says page not found
Why is it not going to music.yahoo.com when the actual query is that?
When I set the suffix to google.com and enter finance in my browser. It just opens google.com and not finance.google.com
Do anyone have any idea of what could be wrong? Any help is much appreciated!!

You are confusing something maybe. net.dns.search adds suffix to searched host names. You pass music, it will append yahoo.com. Ok, you got music.yahoo.com in DNS, but programs thinks it is music.
In HTTP, you specify which host you connect to. And there will be Host: music. Not music.yahoo.com. Server receives music and don't know for which virtual server it should be. Thus it uses default site as fallback.
Is there reason you want it to behave this way? It is intended to save your own time by setting your local domain. But it will not work well on public internet.

Get MAC Address of android device without Wifi

How do I get the MAC-Address of the network interface of an android device which doesn't have a Wifi-Interface (e.g. the android emulator)? WifiInfo obtained via the WifiManager returns null.
EDIT
To be more clear: I have to communicate with an existing network protocol (not designed by me) on the local network where I have to send the mac address of the communicating interface within the payload during a registration phase.

I'm going to take a leap and assume that you want this MAC address in order to establish a unique identifier for the device. Mac Addresses are not the way to do this.
There's an Android Developer Blog post titled "Identifying App Installations" which covers the topic of generating unique ID's fairly well, including the popular methods, and the pros/cons. It's definitely worth a read. Quite relevant to this post is the following quote:
It may be possible to retrieve a Mac address from a device’s WiFi or Bluetooth hardware. We do not recommend using this as a unique identifier. To start with, not all devices have WiFi. Also, if the WiFi is not turned on, the hardware may not report the Mac address.
The options available to you instead include TelephonyManager.getDeviceId(), android.os.Build.SERIAL, and Settings.Secure.ANDROID_ID, all of which are covered in more detail in the linked post.

Read /sys/class/net/[something]/address as a text file
But it's unlikely to be useful in the way you think.

See this post where I have submitted Utils.java example to provide pure-java implementations.
Utils.getMACAddress("wlan0");
Utils.getMACAddress("eth0");
Utils.getIPAddress(true); // IPv4
Utils.getIPAddress(false); // IPv6

What is the network interface you want the MAC address of? If there's no wifi, you certainly can't get the wifi device's MAC address. It represents the physical hardware and if that's not present, it simply doesn't exist.

To get wifi MAC of android device using adb:
adb shell getprop ril.wifi_macaddr
Use the following code in Java to get it programmatically:
Process p = Runtime.getRuntime.exec("adb", "shell", "getprop", "ril.wifi_macaddr")
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream());
String macAddress = br.readLine();

java.net.ConnectException: localhost/127.0.0.1:8080 - Connection refused

I am using xampp apache server to serve resources to the application from my machine. But i am getting the above error.
I got something on the google. pointing towards possible solution here
http://groups.google.com/group/android-beginners/browse_thread/thread/599a06416fb37b4a
What is the solution for the above problem?

Since you have not specified you are connected to a server from the device or emulator so I guess you are using your application in the emulator.
If you are referring your localhost on your system from the Android emulator then you have to use http://10.0.2.2:8080/ Because Android emulator runs in a Virtual Machine therefore here 127.0.0.1 or localhost will be emulator's own loopback address.
Refer: Emulator Networking

in android
Replace: String webServiceUrl = "http://localhost:8080/Service1.asmx"
With : String webServiceUrl = "http://10.0.2.2:8080/Service1.asmx"
Good luck!

localhost and 127.0.0.1 are both ways of saying 'the current machine'. So localhost on your PC is the PC and localhost on the android is the phone. Since your phone isn't running a webserver of course it will refuse the connection.
You need to get the IP address of your machine (use ipconfig on windows to find out) and use that instead of 127.0.0.1. This may still not working depending on how your network/firewalls are set up. But that is a completely different topic.

Add Internet permission in Androidmanifest.xml file
uses-permission android:name="android.permission.INTERNET
Open cmd in windows
type "ipconfig" then press enter
find IPv4 Address. . . . . . . . . . . : 192.168.X.X
use this URL
"http://192.168.X.X:your_virtual_server_port/your_service.php"

You just have to use your local (but real) IP address and port number like this:
String webServiceUrl = "http://192.168.X.X:your_virtual_server_port/your_service.php"
And make sure you did set the internet permission within the manifest
<uses-permission android:name="android.permission.INTERNET" />

If you are using localhost in your url and testing your application in emulator , simply you can replace system's ip address for localhost in the URL.or you can use 10.0.2.2 instead of localhost.
http://localhost/webservice.php to http://10.218.28.19/webservice.php
Where 10.218.28.19 -> System's IP Address.
or
http://localhost/webservice.php to http://10.0.2.2/webservice.php

You just have to use your local IP address:using the cmd command "ipconfig" and your server port number like this:
String webServiceUrl = "http://192.168.X.X:your_local_server_port/your_web_service_name.php"
And make sure you did set the internet permission in your project manifest
It's working perfectly for me
Good Luck

its working for me. I use genymotion for Run App.
1.Firstly i was checked my local ip. goto command mode>> And write ipconfig.
Example: Windows 10>> search cmd>>then Write ipconfig .
2. Then get your local ip information >>>
3.Use give your localhost ip and virtual box ip. You need to use virtual box ip for genymotion.Check below screenshot. You can you below any ip under virtualbox host network

Replacing localhost with 10.0.2.2 is correct, but you can alsor replace localhost with your physical machine's ip(it is better for debug purposes).
Ofc, if ip is provided by dhcp you would have to change it each time...
Good luck!

Solution is very simple.
1 Add Internet permission in Androidmanifest.xml file
<uses-permission android:name="android.permission.INTERNET" />
[2] Change your httpd.config file
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
TO
Order Deny,Allow
Allow from all
Allow from 127.0.0.1
And restart your server.
[3] And most impotent step.
