I need to ask my clients to send me the udid of their iOS devices in order to add them to an adhoc distribution profile. The main problem is that they are used to iOS but not much to computers. Anyway, it would be a pain for me to explain them how to install iTunes (or even Xcode) to get the udid. Most of the tutorials which describe the iTunes process are in english, I don't want to loose time to translate one of them. And even if I do it, I fear that they will not appreciate loosing their time following it. Any suggestion ?
I use a web online tool at http://www.easy-udid.com to get my customers UDID, I think it's the easiest way for them.
Also you can use service http://udid.io
It is easier because you don't need to ask your clients to write your email address. You just send them link “http://get.udid.io/?mail=your#mail.com” and they will need only 5 taps to send UDID on "your#mail.com"

I want to make an application which will send information to a server about user's location every 30min. It is needed to provide location specific push notifications.
I need such functionality for Android/iOS, which would work in background (also if device is restarted). I found some articles covering background services and I created background service doing that, but after phone is restarted it won't work.
Is it possible with Android and iOS? How can I achieve that?
With iOS, no. With Android, yes.
Apple has gone to great lengths to limit what apps can do. You can do some things in the background for an extended period of time (GPS, play audio, Voip, etc), but after a reboot your app will not be restarted until the user opens it again. There are exceptions to this. Voip apps are allowed to restart after a reboot, but apple will not approve your app for the App Store unless you actually have a place for a user in your app to use the Voip feature. Geofences are a possibility, but I haven't had experience with that feature yet. In my experience, Apple does whatever they can to make sure your app doesn't run forever.
With android, there is more flexibility and what you propose is totally possible. I've listed some important links below, since most of those solutions are far better documented than what I can do here.
Essentially you need to register as a boot receiver and then send an intent to start a titanium android service when the boot event is received. I don't have experience with starting a titanium service, but I'm sure its a simple intent you need to fire. Either way you'll need a module for this native code. I attached a link to a bencoding titanium module that may help you, although there may be some others out there. You may even need to code one yourself.
Samsung is notorious for stopping your app with their SPCM feature. You may want to familiarize yourself with it. I've added a stackoverflow discussion link below.
I don't know all of your system requirements but honestly, for any app I would try my best to not run forever. It will hurt the battery life for your users and will add a lot of complexity. Maybe you could simply have the app check the GPS coordinates when it receives a push notification and decide right there and then whether to present a notification to the user? Just something to consider.
Either way good luck!

Dealing with Samsung SPCM killer
Good day all,
I have a java based phone (samsung star 2 5260) and it's three weeks that I'm trying to come up with a solution to receive notification on received emails.
The phone configures a periodic check for a minimum of 30 minutes, but I need a much more frequent control (five minutes maximum).
I have tried countless solutions, and I've come up with the closest one, being a custom mujmail midlet that supports my gmail mailbox over imap, deployed thanks to the netbeans editor.
Point is, I've modified mujmail's polling to run on the background, but audio does not play when the phone is locked, so even if the midlet checks and receives emails, it's unable to notify me. The application minimizes and keeps on running, but it's unable to tell me that new mail has arrived.
I've even tried sending an sms when there's new mail, but was unable to sign the application (looks like ktoolbar produces 1024 bit certificates, and thawte, verisign, etc. will only produce 2048 bit certs since a few years.), and so it'll always ask authorization, which renders this approach useless.
So I'm desperate to find an alternative.
And I was hoping that we can in some way emulate the 'system alert' that the phone uses when it's locked and you receive an sms (audio cue).
Is this a j2me functionality, or is it specific to the samsung sdk?
Does anybody have an idea of how to access this functionality from inside a midlet?
Is there a way to create a midlet in the trusted third party domain without signing it?
I know j2me is an old subject, but hopefully someone here is still knowledgeable about it.
Thanks in advance.
Looks like you're expecting too much from JavaME.
If it's possible to do what you want, you can be certain that it requires signing.
Basically you have to sign your MIDlet with a certificate that is supported on your phone. Most developers go for Thawte or Verisign, because their certificates are supported on the most devices.
If you're only interested in getting this to run on your own phone, it's possible you can find a much cheaper provider, like e.g. Samsung themselves. But I admit I don't know.
In any case, there's no way around signing, when you want to do things like this with JavaME.
(Well.... there's a tiny slim chance that your phone lets you set permissions, like "Never ask" in the MIDlet properties on the phone after installation, but only a tiny slim chance).
Even after signing your MIDlet, it still won't be able to wake up the phone. JavaME is a sandbox. If the user puts the phone to sleep, then JavaME can't wake it up. (At least not without special API's, which I don't think exists).
If it was me, I'd investigate this approach:
Implement PushRegistry timer to launch the MIDlet ever 5 minutes. This should theoretically launch the MIDlet despite the phone sleeping. (But not if it's turned off).
Then attempt if you can play an alarm sound here.
If you can't, then I'd look into sending an SMS to myself.
This question is no longer active - I have been officially notified by the company that we're dropping Android and going with a system that is specifically designed for business use.
In our two sister companies we installed almost 500 android phones assuming they'd have security capabilities similar to Linux that would allow us to provide business phones to our employees but limit their access to apps. Unfortunately we've since found out that we were hugely mistaken. Android has decided that whoever has possession of the phone should have full access to everything. Unfortunately for us this has been a business nightmare, with huge data overages, employees downloading and installing anything and everything they can get their hands on from Play Store, the apps we need to run constantly being stopped by the task manager because too many apps are running at the same time with our employees arguing that the apps are buggy or the phone is broken. Due to our type of operation, the phones are passed from one employee to another often for weeks at a time before a supervisor or technician has access to them.
We absolutely need to either secure the phones or get rid of them. So...
From within a service, how do I capture when an employee clicks on an unauthorized app either from the desktop or from the applications menu? I've spent the last 2 days searching Google for an answer, but have turned up nothing. I know it can be done, because I have a couple of apps on my personal phone that do so.
We're using Android 2.2
Why not uninstall Google play store from the phones? And any other apps which are not needed?
It might be easiest too just install a parental control app. Here's an example, though this particular one may not meet all your needs: https://play.google.com/store/apps/details?id=com.kiddoware.kidsplace
Have a look at the 3CX Mobile Device Manager. The sign up process is free and easy. Then you just need to download the app to each phone from GooglePlay and get it set up. I would be interested in knowing if you proceed with it and if it does everything you need it to.
I want to make my iPhone app display on a Mac's screen, kind of like AirPlay does with other machines. The only way I have heard to do this is, although I do not like it, turn the iPhone into a server. Unfortunately, I cannot figure out how to do so. I also wanted to set it up in such a way that my Mac automatically detects it. I have seen a similar setup in the game Chopper 2. My Mac app will have a simple timer that fires every few seconds to look for the iPhone, in the same way that Chopper 2's "Find iPhone" button does.
Is there a simple way to turn the iPhone into a server, or start a "session" like Game Center does?
One last thing: I know it is somehow possible, because another app I have actually gives my iPhone a web address at the click of a button. It is called the Dicenomicon, if you want proof.
First there is no easy way to redirect your display to Mac, even if you made it a server of some kind.
Second, to discover or publish customized services on WLAN, you may want to refer to the samples on Bonjour:
CocoaHTTPServer: a simple TCP/HTTP server.
WiTap: an app that discovers and connects to services of the same kind on WLAN by Bonjour.
I'm not really sure what you mean by "server", because there is no way to share the screen of an iPhone using the official SDK, although this is possible by jailbreaking.
It would be possible, however, to send data back and forth between the Mac and iPhone, and display the data on the iPhone, on a Mac. Using that data, you could try to recreate the interface on the Mac. All of this could be accomplished using sockets. A class that might help with that would be cocoaAsyncSocket, which makes network programming a lot easier.
The auto-discovery of iPhones on the local network is achievable with Bonjour. Without getting into too many details, NSNetService would allow you to publish a service for your app from an iPhone, and NSNetServiceBrowser would allow you to find that service on the local network from the Mac. From the NSNetServiceBrowser, you could establish a socket connection with the iPhone.
Good luck!
You might want to take a look at the GameKit APIs, I know they do something similar between two iOS devices.
http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/GameKit_Guide/Introduction/Introduction.html
We're working on an exhibit (http://pulse.media.mit.edu) and I'm brand new to iOS, objective-c and Xcode. The exhibit deadline is in one week and I'm stuck.
The problem I'm having seemed simple enough.
Our exhibit has a projector and an iPad. The projector will be hooked up to a mac and be playing a video. The iPad will act as a controller for those videos. More simply:
I have 50 videos on a Mac. I need to develop an application on the Mac, that, when opened will loop one of the videos.
On an iPad, I need to develop an app that can change between the videos on the mac in real time. The iOS app is already designed, we're just struggling with some code.
On the mac, when the iPad tells the Mac to change video, we'd like it to switch between videos using Core Animation, like this (http://youtu.be/pyd8O-2mkgk?t=1m).
So my question: What is the most robust way to do this? It has to be able to run in a museum, for two months. Some things to consider:
We are 4,000 miles away and can't monitor it all the time. We'll
check nightly to see if it's still working, but it should run the day
without breaking.
If people unplug the iPad, it should still work.
It should be as robust as possible.
How can I best do this? Should I write to a database from the iPad onto a database running locally on the connected Mac and then monitor that database 10 times every second? Are sockets robust enough to use alone?
If you do suggest a way, can you please point me in the direction of some resources (frameworks, function names, etc) that can help me do this quickly?
Thank you for your time.
I would go for the server-in-the-middle option, because it will be easiest to debug, and requires nothing more than a working internet (wifi) connection on the client side. When having connection issues, all you need is someone who knows how to hook up an iPad or Mac to the internet. And you can see server-side which device has issues connecting.
Furthermore, using plain HTTP sounds like the best way to go for communication, and the backend can be written in any server side scripting language. Both clients should be polling the server every X seconds.
If you get this basic setup working well before your deadline, you could try to get the devices to connect to eachother directly (for a less sluggish user experience), and leave the server solution in there as a fallback method. The Mac app could function as a HTTP server, accepting the very same commands that the iPad normally sends to your server. The challenge will be to reliably know which IP to connect to. You could hardcode it or use Bonjour.
