I need to implement an app that monitors inbound/outbound connections by different apps on iPhone. my app is going to run in background using apple's background multitasking feature for voip and navigators.
I can use private api as my client doesn't need this app on appstore.
Thanks.
I got through this.
I didn't need any private Api to get information of inbound/outbound active connections.
Its just you need to know basic C programming and some patience.
I wrote to apple dev forums regarding this,and got response as-
From my perspective most of what I have to say about this issue is covered in the post referenced below.

The way to make progress on this is to:
o grab the relevant headers from the Mac OS X SDK
o look at the Darwin source for netstat to see how the pieces fit together
WARNING: There are serious compatibility risks associated with shipping an app that uses this technique; it's fine to use this for debugging and so on, but I recommend against shipping code like this to end users.
What I did step by step is -
1)downloaded code of netstat from BSD opensource -
2)add this to your new iphone project.
3)see,some header files are not present in ios sdk so you need take it copied from opensource.apple.com and add those in your iphone sdk at relevant path under-
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk/usr/include
My xcode version is 4.5.2. so this is path relevent to my xcode. you can have different path according to versions of xcodes.Anyway. and remember to add those headers in both iosSdk & iOSSimulatorSdk both so that code will work on device as well as on simulator.
4)you may find some minor errors in netstat code relating not finding definitions of some structures in header files.e.g " struct xunpcb64 " .dont wory. definitions are present there.you need to comment some "#if !TARGET_OS_EMBEDDED" #else in those header files so that ios sdk can reach in those if condition and access the definition.(need some try and error.be patient.)
5)finally you will be abe to compile your code.Cheers!!
In case you haven't seen this already, I have used it successfully on my iPhone.

I realize it is not exactly what you want.
Generally, I agree with Suneet. All you need is network sniffer.
You can try to do partial port of WireShark (it's open source and it works on MacOS) to iOS. Both iOS and OS X share most part of the kernel, so if it's not explicitly prohibited on iOS, it should work for you.
WireShark is quite big product, so you may be intersted to look for another open source network sniffer which work on OS X.

I am developing an Android app that gets data from Movesense using the GATT profile from the sample app GATT Sensor Data App here.
I followed the tutorial available here. Building the app and getting the DFU worked fine. I can get IMU, HR and temperature data with no issues.
Now I'd like add a tap detection feature to my app. I understand that I have to subscribe to 'System/States', but first I need to be able to receive the system state data.
I understand that I need a modified DFU for that, but I don't understand what changes I should make in which files of the gatt_sensordata_app before rebuilding and generating the new DFU.
What changes should I make in order to broadcast /System/State data?
(I usually just deal with Android so apologies for the very basic question.)
I tried adding #include "system_states/resources.h" to GATTSensorDataClient.cpp but I don't know how to continue.
The normal data straming in the gatt_sensordata_app uses the sbem-encoding code that the build process generates when building the firmware. However /System/States is not among the paths that the code can serialize. Therefore the only possibility is to implement the States-support to the firmware.
Easiest way is to do as follows:
In your python app call data subscription with "/System/States/3" (3 == DOUBLE_TAP)
Add a special case to the switch in onNotify which matches the localResourceId to the WB_RES::LOCAL::SYSTEM_STATES_STATEID::LID
In that handler, return the data the way you want. Easiest is to copy paste the "default" handler but replace the code between getSbemLength() & writeToSbemBuffer(...) calls with your own serialization code
Full disclosure: I work for the Movesense team
I am trying to write a small application usingwebrtc that can be used as a messaging/Chat application between 2 computers.
I see this:
http://simpl.info/rtcdatachannel/
and it is not working. any suggestions?
I wrote the simpl.info/rtcdatachannel example. It's only designed to show off data channels working within one page.
For a complete peer-to-peer messaging application, I suggest adding RTCDataChannel functionality to something like apprtc.appspot.com. You could also consider a readymade abstraction library like PeerJS or EasyRTC.
You might also want to take a look at the RTCPeerConnection/RTCDataChannel/signaling codelab I built.
In above example, from the trace log, the ice-candidates are generated, but they are either not exchanged between each other because of there may be problem in sending 'offer' or responding the 'answer'. Also above example works only in chrome( because of only webkitRTCPeerConnection is used, with mozRTCPeerConnection this can work on firefox also.
If you want to develope chat application for only text and not for the video chat, then you can use node-js & socket.io or websockets for this.
You may like :) following two libraries:
DataChannel.js / for webrtc data/text/file sharing (among multi-users)
RTCMultiConnection.js / for data as well as media (screen/audio/video/etc) sharing
Firebase.com is a "suggested" starting point for newcomers; that can be used for signaling. You just need to override "openSignalingChannel" and done!
You should use peer.js (https://github.com/peers/peerjs) or use peer chat (https://github.com/Hironate/PeerChat) if you want to do with node js.
I need just a simple Objective-C app or API that can send and receive IMs to a single user.
BARE BONES.
I've looked at Skype, but the Objective-C part looks really outdated. AIM is preferred, but anything that can send and receive IMs is perfect.
Is there an API for this? For AIM or Skype?
Examples would be appreciated, and remember, I'm totally new to Obj-C.
I don't know about simple or bare bones, but Adium is a good open-source IM client for OS X written in Cocoa.
UDPATE: You might want to check out this blog post ("Towards an Open Source XMPP Framework for Cocoa"). It looks like the author wanted his own Jabber/XMPP Cocoa framework, too, and has even created a project for it in Google Code.
I am currently working on an Objective-C implementation of the OSCAR (AIM) protocol. It is being updated on GitHub. If I understand what you want to do correctly, the library, although incomplete, will meet your needs. It can send and receive messages, and work with status messages. It can also read the buddy list if you are interested in that. The entire library should be finished by the end of the month, and you can check it out on GitHub:
https://github.com/unixpickle/LibOrange
Signing on is this simple:
login = [[AIMLogin alloc] initWithUsername:username password:password];
[login setDelegate:self];
if (![login beginAuthorization]) {
NSLog(#"Failed to start authenticating.");
abort();
}
Once signed on, sending messages works like this:
AIMMessage * reply = [AIMMessage messageWithBuddy:[message buddy] message:#"Test"];
[theSession.messageHandler sendMessage:reply];
Obviously, you can check out the sample on GitHub, but I thought I would put that sample code to wet your appetite. Enjoy!
I don't know exactly how hard it would be to use, but isn't there an open source library for accessing IMs called libPurple? maybe you should check that out and see what it can do in Xcode.
If it's for a small scale deployment, it would be pretty easy to roll your own using Distributed Objects. I've heard it can be problematic trying to use DO for a high traffic Internet service though.
I am trying to detect when particular applications are launched.
Currently I am using NSWorkspace, registering for the "did launch application" notification. I also use the runningApplications method to get apps that are currently running when my app starts.
For most apps, the name of the app bundle is enough. I have a plist of "known apps" that I cross check with the name of that passed in the notification.
This works fine until you come across an app that acts as a proxy for launching another application using command line arguments.
Example: The newly released Portal on the Mac doesn't have a dedicated app bundle. Steam can create a shortcut, which serves as nothing more than to launch the hl2_osx app with the -game argument and portal as it's parameter.
Since more Source based games are heading to the Mac, I imagine they'll use the same method to launch, effectively running the hl2_osx app with the -game argument.
Is there a nice way to get a list of the arguments (and their parameters) using a Cocoa API?
NSProcessInfo comes close, offering an `-arguments' method, but only provides information for its own process...
NSRunningApplication offers the ability to get information about arbitrary apps using a PID, but no command line args...
Is there anything that fills the gap between the two?
I'm trying not to go down the route of spawning an NSTask to run ps -p [pid] and parsing the output... I'd prefer something more high level.
You could use whatever ps uses, though it isn't cocoa based. According to Singh, ps is based on kvm and sysctl calls. Pouring over the source, the pertinant calls seem to be kvm_openfiles, kvm_getprocs and kvm_getargv. To get the command line arguments, first call kvm_openfiles to get access to the kernel memory space, then use kvm_getprocs to get kernel process info, then kvm_getargv.
The use of sysctl in ps seems less relevant to your goal; it's used to get other information, such as the group ID and parent proces ID. The particular sysctl name used is {CTL_KERN, KERN_PROC, KERN_PROC_which, flags}, where which specifies a process filter (e.g. ALL, PID) and flags are arguments for the filter (the details are in the sysctl man page).
OS X doesn't have support procfs, but Singh developed a FUSE based version, released under GPLv2. If you bundle it with your application, you'll have to release it under GPLv2 as well. Most of MacFUSE is released under a BSD-style license, so it can be distributed with your app without making it open source (fusefs/fuse_nodehash.c is released under Apple's open source license, but it also allows linking to closed source apps).
The question "Get other process' argv in OS X using C" should be of use, as it has sample code using kvm and sysctl. TN 2050 "Observing Process Lifetimes Without Polling" may also be of use to you.
Nope - running ps is your best bet. Standard process info interfaces aren't supported on OS X (noop versions were provided in OS X 10.4, but removed thereafter) and the private interfaces are likely to change between OS X revisions.
If you're willing to lock yourself into a single OS X version, all the source is available, for example for ps or libproc; you'll also need to run as root.
The tiny question is:
How to start (realplayer ?) playing given online resourse (e.g. http://example.com/file.mp3)
PyS60, C++ or C# via RedFiveLabs would do.
EDIT1: Title changed from "Start RealPlayer on symbian" to the more appropriate.
I think the title is a little misleading if you just want to play back media content and not use a particular application for it.
In C++ there is CMdaAudioPlayerUtility::OpenUrlL() but it's not widely implemented. For example in S60 it will complete with KErrNotSupported status. To play files you can use other open functions in CMdaAudioPlayerUtility such as OpenFileL() or OpenDesL() but you need a separate mechanism for retrieving the files or at least the bytes onto the device.
There is also CVideoPlayerUtility::OpenUrlL() which supports rtsp audio streams but not http.
