Featureset for AirTracer Revealed
We can now reveal the featureset for AirTracer and AirTracerLite
AirTracerLite is on track to be submitted to Apple for review last week in January. We anticipate a Typical 2 – 3 week review so you should see it in the App Store in February. Both AirTrackerLite and AirTracerPro are the perfect debugging tool when you can't use xcode or instruments. Such as remote QA testing or working with Apple external accessories.
Gabrielle Larose our Art Director and UI advisor is finishing up the promo art and we will post it here as soon as it’s available.
AirTracerLite will be free and include:
- Full Apple System Logger ASL viewer – See all System and console messages on your IPhone
- Full Process Viewer – see all the processes running on your Phone
- Save Logs. View on your IPhone, ipad, ipod touch or remotely in any webkit capable browser Safari or Chrome recommended.
- Cross Platform log viewer using exclusive microsite web technology.(want to learn more?)
- Email your logs to a work-mate or even yourself
AirTracerLite is roughly equivalent in features to Android CatLog which was its inspiration.
AirTracer Pro will have a price point of 1.99 and include all the above features plus
- Remote trace viewer supports multiple transports tcp, http. We will supply tracing tools that can be staticly linked with your code...
- In addition to emailing your logs if you have an Icloud account you can save your logs to the Cloud.
- View and Kill memory hogging or annoying background processes.
- Upload snapshots of your logs and Collaborate on our very special Twitter support group.
- Exclusive feature - Display your logs using Airplay mirroring on your ipad2, Apple TV or any Airplay supported display.
- Exclusive Feature – log and Listen, A soothing musical score will play on a single track via the internal speaker while the logger traces your application in the background (we did our homework on this one and expect no issues from Apple Review) also works with silent audio tracks.
AirTracer Pro will follow shortly after AirTracerLite, we hope to incorporate user feedback and suggestions from the Lite Product. AirTracer Pro will have some unique features that may cause a lengthy Apple Review, However we feel they are important enough to take the risk.
Android version coming later this year. Are you an Android developer, want to help us build this exciting tool, contact shelly@mooncatventures.com

IOS multitasking and external accessories part II
In this segment continuing our discussion on IOS external accessories and Multitasking we are going to look at ways an application can be launched without any action on the part of the user.
Case Study:
In-car navigation and management systems , so called infotainment systems. These are Radio head units that may offer depending on the OEM Handsfree calling, messaging , navigation and control over the vehicle's environmental systems. Examples would be SYNC from Microsoft and Ford, Mylink from GM and Entune from Toyota.
All of the above named systems and many others also provide some level of integration between the Radio Headunit and Applications on the Driver's Mobile device Using simple steering wheel or voice controls. Pandora Radio is a widely included application, But the list is growing.
These infotainment systems have special challenges associated with them in that many State Legislature and NTSB are developing strict regulations for Driver Distraction, Mandating and in some States enforcing use of handsfree devices for making calls and limiting certain control of the equipment to when the vehicle is at rest or a safe speed. No one whats to see an accident report that states the driver hit the pedestrial while their attention was focused on Searching for "lost control" by Unwritten Law.
These systems work with a few smart phones e.g. Blackberry, Android and Iphone. Android is by far the easiest to interface with Android devices can connect to these systems via bluetooth socket connections. Since Android allows for true multitasking, multiple socket connections can be opened it is fairly simple for the infotainment system to provide a mechanism to swap from application to application.
Apple presents a more difficult challenge. Apple didn't add Bluetooth Support to the MFI certification until after many of the current crop of devices were on the market which means that for these devices the only connection available is using the I(Pod,Phone,Pad) accessory protocol or IAP over the dock Connector which is a serial connection.
IAP is a very simple control protocol which uses standard serial RS232 . With the Approved apple api the only way you can do serial communication between an iphone and another device is using an MFI approved appliance. There are a few backdoor approaches to serial communication involving copying portions of the IOKit api from mac OS or jailbreaking the device and installing a serial port handler but for an application that the developer hopes to get through the Apple Review process the only approved way is to use the Apple Dock Connector and belong to the MFI program.
All MFI accessories include a decoder chip, the dock connector also has a decoder chip, when the IDevice is connected to the accessory the devices go through something resembling an ssl handshake, After successful authentication The TTY port is available for standard communication. The IAP framework handles all the low level conversions , the user's application uses the standard IOS stream protocol for all traffic.
The whole process is fairly fluid but there is a major flaw, only one accessory can be connected at a time and because of the lack of multitasking only one app can be connected to the accessory.
With the latest ios apple has introduced Airplay and Bluetooth 4.0 , Bluetooth 4.0 is a recent standard for new low powered bluetooth devices now coming on the market. It is clear that apple plans Airplay to be the new direction for all future accessories.
Apple announces new MFI components
This is an exciting new direction but software is a lot easier to change than hardware, and new chips mean new engineering and with regards to Automotive product cycles can mean months or years before the public sees it. Meantime what about current hardware.
With IOS 5 Apple has tried to address this issue by providing a new notification to the Accessory. A current generation accessory can now send an IAP command to the device to alert the user to Launch a particular app. "Health Monitor needs your attention" Allow or Dismiss. For the heart monitor example the user simply taps "allow" which starts the application bringing it to the foreground. This is a great improvement it means the User doesn't have to search for the app icon on the phone or remember which app was used with the accessory, But still presents problems for a driver who must take their eyes off the road to tap the allow button. Better but not useful just yet.
I have observed a regulatory test of an infotainment system . The test consisted of the smart phone being paired with the system and then the device placed in the cars glove compartment. From that point on the only way to interact with the apps on the phone was via the handsfree microphone or steering column buttons.
Apple also included new commands to send meta data to existing MFI accessories. eg. Artist, title etc. Nice touches but still for existing accessories it means that the user has to select a favorite app ie Pandora Radio and stick with it until they can safely (or unsafely) switch to another application.
But.. A method has existed since IOS 2 for launching applications without using the application springboard. That method is the custom URL Scheme. Apple uses custom url schemes for many standard applications. If you open Safari and type mail://johnsmith@apple.com, Safari will close (or nowadays go into background) and the mail application will open. You can designate custom url schemes for any native applications including the phone application and facetime or define schemes for your own applications.
To communicate with an app using a custom URL, create an NSURL object with some properly formatted content and pass that object to the openURL: method of the shared UIApplication object. The openURL: method launches the app that registered to receive URLs of that type and passes it the URL. At that point, control passes to the new app.
NSURL *myURL = [NSURL URLWithString:@"Pandora://play?Sweet+Dreams&artist=sucker+punch"]
|
The above code snippet assumes the Pandora app developer has coded a url handler which would process the search query specified on the url.
To create an application with a custom URL scheme
|
1.
|
Right-click the Information Property List key, and select Add Row. Select “URL types” from the list .
Adding a URL type.
|
|
2.
|
Expand Item 1, right-click URL identifier, and again select Add Row. Select URL Schemes from the list
|
|
3.
|
An app that has its own custom URL scheme must be able to handle URLs passed to it. All URLs are passed to your app delegate, either at launch time or while your app is running or in the background. To handle incoming URLs, your delegate should implement the following methods:
-
Use the
application:didFinishLaunchingWithOptions:method to retrieve information about the URL and decide whether you want to open it. This method is called only when your app is launched. -
In iOS 4.2 and later, use the
application:openURL:sourceApplication:annotation:method to open the file. -
In iOS 4.1 and earlier, use the
application:handleOpenURL:method to open the file.
If your app is not running when a URL request arrives, it is launched and moved to the foreground so that it can open the URL.
if your app is running but is in the background or suspended when a URL request arrives, it is moved to the foreground to open the URL.
The system calls the delegate’s application:openURL:sourceApplication:annotation: to check the URL and open it. If your delegate does not implement this method (or the current system version is iOS 4.1 or earlier), the system calls your delegate’s application:handleOpenURL:
Using the information above it is a fairly trivial task to construct a simple launcher with a button representing each application providing a function and the IBOutlet of the button having the code to openURL to the application.
-(IBAction)openSms {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://466453"]];
}
Its also not very difficult to see how you can code a simple voice command application using Siri or Nuance.
- (void)recognizer:(SKRecognizer *)recognizer didFinishWithResults:(SKRecognition *)results
{
if ([results.results count] > 0) {
NSString *wellFormedRequest =[self getUrlRequest:[results firstResult]];
if (wellFormedRequest != nil) {
NSURL *url = [NSURL URLWithString:wellFormedRequest];
[[UIApplication sharedApplication] openURL:url];
}else{
[self speakText:MESSAGE_I_DID_NOT_UNDERSTAND_Y0U];
}else {
[self speakText:MESSAGE_NO_RESULTS_RETURNED];
}
}
In the code snippet above for a typical speech recognizer the method didFinishwithResults passes the results of the speech transcription to getUrlRequest which returns either a well formed url request in the form of appName?parameters or nil if the request couldn't be mapped to an application. The Url request calls openUrl which opens the application and puts the launcher into the background.
If getUrlRequest returned nil or [results count] = 0 then an appropriate message is passed to the text to speech engine.
So now we have a fairly decent little voice controlled launcher that can be used by any handsfree device not just MFI external accessories. Its easy to imagine one of those small bluetooth headsets e.g. Jambra used as a voice interface to your applications. This is quite possible using the new WB 16KHZ SCO support in IOS 5.
So now with a voice command we can start an SMS message, listen to Pandora Radio or get the latest Podcast from Stitcher. Our launcher has all the compatible phone apps hardcoded into a list of choices.
But.. What is the application isn't available on the device. It would be nice to find all the Applications that are present on the phone and compatible with the accessory.
At First thought you might consider as each application is started and backgrounded it writes its Id to ICloud after all isn't that what the IOS 5 "key value storage" feature is for , storing small bits of data usually for restoring the state of the app. Such as the page the reader is on in an ebook reader application.
But Icloud requires an internet connection, and it would be ideal if the launcher had as few dependencies as needed.
The next consideration might be, when an application starts it could register with the accessory , and the accessory could keep a list of active applications but this may require special coding on the accessory . Accessory code is usually embedded into firmware that must be flashed to add new features, For some Accessories this may only require an Over the Air update but for others as previously mentioned this could be a complex and time expensive task. And we wanted the launcher to function with non-MFI devices like the Jambra Headsets mentioned .
A somewhat simpler approach is to use a little bit of standard c code to provide an enumeration of all the running processes on the Device. Much like that pictured below in The AirTracer Processes View. A shameless plug for Airtracer which can List all the processes on an IDevice and there related PID and other information. AirTracer Pro can also terminate processes as well.
Once we have the list of Processes we can build a list of voice commands by comparing the process list against the hardcoded list of compatible processes.
A fragment from a typical siri voice tree using the above technique might go as follows.
User: Sir please play "Sweet Dreams" by Eurythmics
Siri: Ok , I found 2 applications on your device that can play the original mix of Sweet Dreams", Spotify or Tunes , which app would you like to you.
If the user replies Tunes Siri will launch etunes and play the the requested single, if the user fails to respond either Spotify or Tunes may be launched depending on which application the user has selected as a default.

IOS multitasking and external accessories part III - HealthMonitor First Cut
So now using All the information presented so far we can turn to our hypothetical Marathon Runner trainee. She has the Pulse monitor band wrapped around her wrist and the Jambra headset mic over her right earlobe. Using the headset she can switch between Music applications on her phone as well as call up spoken statistics from the HeartMonitor application. She can also Post her progress to her Facebook Wall using the HealthShare application.
The Heart Monitor accessory allows for a single serial radio connection.
When she requests the Heart Monitor application using a voice command, HealthMonitor starts if it's not running already and connects to the Accessory. The launcher enters background and then is suspended because it's not one of the apps "blessed" to run in the background. On receiving AccessoryDidConnect HealthMonitor issues an OpenUrl request for the Launcher. HealthMonitor moves to the background but because it is a "background allowed" application it stays connected to the accessory and can still alert the runner of changes in Pulse Rate via notification Alerts.
The User now issues the "Pandora" voice command to start Pandora Radio, once again the Launcher moves to the background and is suspended. HealthMonitor continues to receive updates from the Accessory.
Pandora now is in complete control, until the runner exits it. after which Pandora enters applicationDidEnterBackground and issues an openUrl back to the launcher. Now the Launcher is the foreground application, HealthMonitor continues to run in the background.
She can continue this round Robin cycle between opening applications, bringing to foreground or sending to backgrounds indefinitely. HealthMonitor will continue to receive updates until it becomes disconnected from the heart monitor or another forground app opens a EASession.
HealthMonitor talks to the heart monitor accessory using the ubiquitous NSStream that apple uses for virtually all stream connection. The same protocol can be used for tcp, bluetooth and IAP.
The runner now issues a voice command to start HealthShare, as before the launcher enters the background and shortly after a suspended state. HealthShare does open a session to the accessory. When HealthShare opens a stream to the heart Monitor HealthMonitor receives a NSStreamEndEncountered message , Since HealthMonitor no longer has an active session to the accessory it will eventually be suspended until such time it is brought again to the foreground. HealthShare issues an openURL request to the Launcher and enters the background. It is still receiving updates from the accessory.
Reality check : There doesn't seem to be any means to start an application in the background it must be "pushed" there by a foreground application, so apps must be specifically coded to return to the launcher with the openUrl method. Unfortunately there is no voice controled version of Pandora, the app mentioned here is simply a hypothetical version.

AirTracer coming soon
Our first Comercial Application AirTracer an Advanced logger and debugging tool for your IOS applications. We are agressively having the lite version of the application available for Apple review by the end of January. AirTracer will make IOS debugging less painful . Watch for the official announcement soon.
Learn more about AirTracer in our IOS Debugging Tips blog which we will be adding to weekly until the release of the application.
Along with AirTracer we will be providing a Twitter support site were Developers can share debugging problems and collaborate on log snapshots uploaded by AirTracer users.
Microsites
We promised you expanded blogs or themes. Our first theme is Microsite. AirTracer uses microsites to provide a common User Experience across all platforms. Andriod, Iphone and browsers that support webkit, while still providing a basic web page for unsupported browsers such as internet explorer. This is used for the remote console logs and trace reports.
In this theme we are going to build a little application called Smart Photos. Some of you may recognize Smart Photos as similar to a project we started back in 2010 but never completed. Photostream. (I believe we coined that term long before Apple. We started referring to Photostream as far back as 2007).
We recently decided to resurrect some of photostream as a way of sharing ICloud content between Facebook, Apple Devices and Android .
A very Quick Overview of this theme, the images are from StreamShare, the new incarnation of PhotoStream but the flow with the exception of the tabbar is similar.
Images are imported to a sqllite data base from the photoAlbum and put into the documents folder, you could (and StreamShare does) use the Asset Library, but for simplicity we will just store photos in the documents folder and a thumbnail in the database. These are displayed in a simple tableview as shown in the first image above. The second screen is the sharing viewcontroller which starts a small http server and publishes its socket address using bonjour. JMDMS would be used for the equivelant Android version.
This series of images is the Microsite broswer. The same browser would be included in all mobile platform versions of the application.
The Actual code creates a webpage with the documents directory as its root. On a desktop web browser a Simple image list is shown. But on the microsite broswer the div with the id json is used.
Json code for the images is embedded in the webpage but only seen by the special Microsite browser.
<html><head><title>Files from </title><style>html {background-color:#eeeeee} body { background-color:#FFFFFF; font-family:Tahoma,Arial,Helvetica,sans-serif; font-size:18x; margin-left:15%; margin-right:15%; border:3px groove #006600; padding:15px; } </style></head><body><a href="..">..</a><br />
<a href="IMAGE_0001.jpg">IMAGE_0001.jpg</a> ( 59.9 Kb, 2012-01-04 00:33:13 +0000)<br />
<a href="IMAGE_0002.jpg">IMAGE_0002.jpg</a> ( 45.6 Kb, 2012-01-04 00:33:32 +0000)<br />

<div id='json' style='display:none'>{{"results":[{"name": "IMAGE_0001.jpg"} ,{"name": "IMAGE_0002.jpg"} ,{"name": "IMAGE_0003.jpg"} ,{"name": "IMAGE_0004.jpg"} , {"name":"test1"} ]}}</div></body></html>
Below is the javascript code embedded in the browser that does the json parsing and displays the table view in the webpage.

StreamX coming along
We've decided on a release date for streamX , Summer 2010.
It may be competed sooner but there always seems to be just one more thing...

Possible transcoding server candidate
As mentioned previously we have two choices for a transcoding server write one ourselves or find one that meets our requirements.
Our research into using Tversity did not go very well and basic questions about how the server transcodes put to the support forum went unanswered. We decided it wasn't worth the effort.
Next we looked at ps3mediaServer, this one is more promising.
It seems to be very dlna compliant and our bridge had no problems "taking" to it, passing basic upnp commands.
A few more promising facts.
- GPL license, we would of rather had mit or lgpl but we can live with gpl.
- Written in java. We have allot of java experience.
- Standard transcoding methods , mcoder, ffmpeg
- Works well with properly formated iphone media
Problem areas
- Transcoding does not work with iphone
- VLC streaming does not work
Planned approach
Branch project and create iphone specific version.
Planned additions
- Support apple http streaming tools beta 3
- Apple push notification support to monitor conversion and report back to device.

Adding savetoAlbum to the TTPhotoViewController
It was fairly easy to modify the three20 photoViewController for the uiActionList and saveToPhoto toolbar buttons.
In TTPhotoViewController modify these lines
_clickActionItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:
UIBarButtonSystemItemAction
//TTIMAGE(@"UIBarButtonReply.png")
target:self action:@selector(clickActionItem)];
UIBarButtonItem* playButton = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:
UIBarButtonSystemItemPlay target:self action:@selector(playAction)] autorelease];
playButton.tag = 1;
UIBarItem* space = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:
UIBarButtonSystemItemFlexibleSpace target:nil action:nil] autorelease];
_toolbar = [[UIToolbar alloc] initWithFrame:
CGRectMake(0, screenFrame.size.height - TT_ROW_HEIGHT,
screenFrame.size.width, TT_ROW_HEIGHT)];
_toolbar.barStyle = self.navigationBarStyle;
_toolbar.autoresizingMask = UIViewAutoresizingFlexibleWidth
| UIViewAutoresizingFlexibleTopMargin;
NSString *searchCaption = @"Photo from networked";
NSRange range = [[_centerPhoto caption] rangeOfString:searchCaption];
if (range.location == NSNotFound) {
_toolbar.items = [NSArray arrayWithObjects:
space, _previousButton, space, _nextButton, space,_clickActionItem, nil];
[_innerView addSubview:_toolbar];
}else{
_toolbar.items = [NSArray arrayWithObjects:
space, _previousButton, space, _nextButton, space, nil, nil];
[_innerView addSubview:_toolbar];
}
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { } - (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex { if(6 == actionSheet.tag) { if(0 == buttonIndex)//save page { NSLog(@"photo: %@", [_centerPhoto URLForVersion:TTPhotoVersionLarge]); NSURL *aUrl = [NSURL URLWithString:[_centerPhoto URLForVersion:TTPhotoVersionLarge]]; NSData *data = [NSData dataWithContentsOfURL:aUrl]; UIImage *img = [[UIImage alloc] initWithData:data]; NSLog(@"photo:class %@", [img class]); UIImageWriteToSavedPhotosAlbum(img, nil, nil, nil);
And add this towards the bottom
.
