  • how to track Google Analytics of Adobe Air app?

    - by dreagan
    I have written an Adobe Air desktop application that tracks a bunch of websites and displays images from the websites in the app. And instead of keeping my mouth shut about it and making it look like an attack on the website, I'd like to make it so that the webmasters can see that these pageviews are made by my application. Is there any way the webmaster could distinguish adobe air access of the website from normal visitor browsing? Perhaps by adding something to the URLrequests I make in the application..?

  • Is there any way to enable the HiDef graphics profile property on a Silverlight 5 3d Web App?

    - by Daniel
    I have an XNA Windows Game that uses the HiDef profile to load complex fbx and obj files. Trying to move it over to a Silverlight 3d Web App, Silverlight seems to only want to use the Reach profile, and I get an error that the Reach profile does not support a sufficient number of primitive draws per call. Is there any way to change to HiDef in Silverlight 5? It is not in the project properties and attempting to change it in mainpage.xaml.cs only gives me the option of setting it to Reach.

  • Web app to take screen shot of website and annotate?

    - by Anagio
    Does anyone know of a website that will take a full screen shot of another website and let users write notes over it then send that annotated photo by email or private link? Basically looking for quicker way to write notes on a site other than taking a screen shot my self and putting it into photoshop. Just an update, I don't need any browser extensions which I already have and do the same. I'm looking for a website app which does this to give to a client.

  • iOS + cocos2d: how to account for sprite's position for the different device dimensions in an universal app?

    - by fuzzlog
    All the questions I've seen regarding iOS universal apps (with or without cocos2d) deal with the "how to add graphics to a universal app". My question is, how does the code need to be written to ensure that the sprites appear appropriately on the screen (given that an iPhone 5's resolution is not proportional to an iPad's resolution)? Is it just a bunch of "if" statements and duplicate code or do iOS/cocos2d provide common function calls that will place the sprites at an appropriate position?

  • nginx proxy_pass POST 404 errors

    - by Scott
    I have nginx proxying to an app server, with the following configuration: location /app/ { # send to app server without the /app qualifier rewrite /app/(.*)$ /$1 break; proxy_set_header Host $http_host; proxy_pass http://localhost:9001; proxy_redirect http://localhost:9001 http://localhost:9000; } Any request for /app goes to :9001, whereas the default site is hosted on :9000. GET requests work fine. But whenever I submit a POST request to /app/any/post/url it results in a 404 error. Hitting the url directly in the browser via GET /app/any/post/url hits the app server as expected. I found online other people with similar problems and added proxy_set_header Host $http_host; but this hasn't resolved my issue. Any insights are appreciated. Thanks. Full config below: server { listen 9000; ## listen for ipv4; this line is default and implied #listen [::]:80 default_server ipv6only=on; ## listen for ipv6 root /home/scott/src/ph-dox/html; # root ../html; TODO: how to do relative paths? index index.html index.htm; # Make site accessible from http://localhost/ server_name localhost; location / { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. try_files $uri $uri/ /index.html; # Uncomment to enable naxsi on this location # include /etc/nginx/naxsi.rules } location /app/ { # rewrite here sends to app server without the /app qualifier rewrite /app/(.*)$ /$1 break; proxy_set_header Host $http_host; proxy_pass http://localhost:9001; proxy_redirect http://localhost:9001 http://localhost:9000; } location /doc/ { alias /usr/share/doc/; autoindex on; allow 127.0.0.1; allow ::1; deny all; } }

  • How do I get started with the M-Project is a Mobile HTML5 JavaScript Framework on Windows?

    - by Bruce Whealton
    This website for this great tool, call the M-Project says that I will need to add a doskey like this: doskey espresso=node C:\Path\To\Espresso\bin\espresso.js $1 $2 $3 $4 (It is a tool for creating Native mobile apps with the Phonegap/Cordova library, and it seems to be something that would be very helpful in this process). If I enter that at a command prompt in Windows 7 or 8, it's not going to stick around or persist. Is it an Environment Variable? Then it says at this page: http://www.the-m-project.org/ that it will work with Windows with some additional tools installed. The next line says that Node.js is needed, so I don't know if that is the additional tools mentioned above. Also, in an old discussion I read that one could just install cygwin. What would that do? It doesn't actually install any of the Linux distributions. I did install Ubuntu 12.04 server with VirtualBox because I thought it would be good to learn more about using Linux as I manage websites that are on a dedicated host. Anyway, the suggestion to install cygwin did not go into any details... I guess it would allow one to create a bash profile?? which would only work in a cygwin Command Line Window. Is that right? Isn't there a similar file that one could use in Windows or an Environment Variable that one could set to be able to achieve the same result? Thanks, Bruce

  • How do I debug a crash when I run my garbage-collected app in Rosetta?

    - by Rob Keniger
    I have a Universal app which is targeting 10.5 and which uses garbage collection. I am building for ppc, i386 and x86_64. I don't have access to a physical PowerPC machine so I am trying to use Rosetta to confirm that the PowerPC portion of the app works correctly. However, as soon as the app is launched in Rosetta it immediately crashes with the following crash log: Process: FooApp [91567] Path: /Users/rob/Development/src/FooApp/build/Release 64-bit/FooApp.app/Contents/MacOS/FooApp Identifier: com.companyX.FooApp Version: 0.9 (build d540e05) (2) Code Type: PPC (Translated) Parent Process: launchd [708] Date/Time: 2010-04-09 18:32:23.962 +1000 OS Version: Mac OS X 10.6.3 (10D573) Report Version: 6 Exception Type: EXC_CRASH (SIGTRAP) Exception Codes: 0x0000000000000000, 0x0000000000000000 Crashed Thread: 5 ...snip non-relevant threads...

It looks like the Garbage Collector is failing very badly. Are garbage-collected PowerPC apps not supported in Rosetta? I can't see any mention of this limitation in the docs if so. Does anyone have any ideas?

  • How to set up RPX widget and facebook app to be able to authenticate with rpx_now?

    - by Andrei
    Using the sample app for rpx_now gem ( http://github.com/grosser/rpx_now_example) on localhost:3000, I have successfully logged in via Google Accounts, myOpenID, Yahoo, but cannot make it via Facebook. In the RPX app/widget settings I have set my facebook-app key and secret. In my facebook app settings, the Connect URL is myappname.rpxnow.com. But when I try to connect, then I don't even see a facebook login page, just a number of redirects and I am back to my localhost with the following exception http://gist.github.com/386520 . Before I was successfully connecting with oauth2 gem, however, without fetching user data - only authentication. That time I set only key/secret and localhost as my Connect URL. Currently, I don't even ask for email etc., but still the same problem. Can it happen because rpx_now cannot get requested user data from facebook? Or it is a problem of facebook key/secret? May be I need to provide more settings of my facebook app?

  • My Rails app is returning HTTP 500 for all its URLs, but nothing shows up in the log file. How can I

    - by mipadi
    I have a Rails app that is running on a production server with Apache and Phusion Passenger. The app works fine locally when using Mongrel, but whenever I try to load a URL on the production server, it returns HTTP 500. I know the server is working properly, because I can get the static elements of the application (e.g., JavaScript files, stylesheets, images) just fine. I've also checked the Passenger status and it is loading the app (it must be, since the app's 500 Internal Server Error page is returned, not just the default Apache one). Also, when I load the app via script/console production and do something like app.get("/"), 500 is also returned. The problem is that there is nothing in the log files to indicate the problem. production.log is empty. The Apache error logs show no problems with Apache, either. I'm stumped as to what's going on and I'm not sure how to diagnose the problem. I know I may have been a bit vague, but can anyone give a suggestion on what the problem may be? Or at least a way I can go about diagnosing it?

  • how do I get only the stack trace from my app in rails?

  • How to flush DNS cache in Windows Mobile programmatically?

    - by Bounded
    Hello, My windows mobile application (written in C# with the compact framework) needs to know if a particular machine is active or not. To achieve this goal, I thought to use a ping mechanism. I tried to use the Ping class implemented in the opennetcf framework (the System.Net.NetworkInformation.Ping class for the .NET Framework is not part of the compact framework). Because I give to the Ping.Send function a host name, it first tries to resolve this host name and to retrieve an IP address. But i observe the following problem : If the first dns resolution fails (because the network is down at this moment), and if the application tries immediately again to send the ping, it fails too, even if the network is note down anymore. I check with a famous network protocol analyzer and i saw that only the requests concerning the first dns resolution are sent. The requests concerning the dns resolution of the second ping are not sent. Why is the second dns request not sent ? Is there any dns cache mechanism on such Windows Mobile devices ? If yes, can this mechanism beeing flushed programmatically ? EDIT : I gave up finding a solution to this DNS flush. I chose to ping an IP adress instead of a name machine. The problem of pinging an hard coded adress IP is that we have to be 100% sure that this IP will not change. The gateway IP can be used because it's always reachable (if it does not, it means the network is down).

  • Dockable panes created in CChildFrame not visible the second time the app. starts.

    - by Nijenhuis
    Hi, I have created some dockable panes in CChildFrame::OnCreate() The first time i start the application they are shown. The second time i start the application they are created but the splitterwindows are completly against the sides of the clients area (bottom and right), so not visible. So i have to use the mouse to pull the splitters into the clientarea so that the dockable windows become visible again. If i do File-New in my app a new client window is created and showing the dockable windows as they should be. I Think this has something to do with saving the windows layout in the registry, because if i change SetRegistryKey(_T("61sakjgsajkdg")); in the CWinApp derived class of my app. and rerun they are shown again the first time. (but not the second time i restart the app). How can i save the layout of those dockable windows as well, so if i restart my app. they are visible ? Or else how do i prevent my app. of overwritting the window layout with the one previously saved. Something to do with LoadCustomState() and SaveCustomState() ?, i could no find any info on howto implement those methods. I have here a link to the demo project to demonstrate what i mean: http://www.4shared.com/file/237193472/c384f0f6/GUI60.html Could someone tell me how to show those dockable windows in my CChildFrame class the second time the app starts?

  • How to implement a single instance app manager in java (CVM PhoneME)?

    - by Marcus
    Hi, I'm working on a application manager for embeded platform based on the CVM PhoneME VM. The VM is started by a C++ app which configures the CVM and then triggers the VM itself. This C++ app is called form the command line passing the main class name and the classpath of a java application. There is a main java app (lets call it Manager) which loads the app using classloaders. I want this manager to be a single instance application so it could track all running apps. In other words: The first time I start an app (app1 for instance), the VM will launch and the Manager will load the app1. In further calls to load other apps (app2, app3 and so on), the same instance of the Manager would load those apps. The manager is working fine, except for the fact that this is not a single instance. Is it possible to do what I want? I found this: http://www.knowledgesutra.com/forums/topic/59760-how-to-implement-single-instance-application-on-java/ This is almost the same I want, except for the app loading part. However, the necessary packages are not available in the CVM implementation. Thanks very much.

  • Battery drains even with app off screen, could it be Location Services doing it?

    - by John Jorsett
    I run my app, which uses GPS and Bluetooth, then hit the back button so it goes off screen. I verified via LogCat that the app's onDestroy was called. OnDestroy removes the location listeners and shuts down my app's Bluetooth service. I look at the phone 8 hours later and half the battery charge has been consumed, and my app was responsible according the phone's Battery Use screen. If I use the phone's Settings menu to Force Stop the app, this doesn't occur. So my question is: do I need to do something more than remove the listeners to stop Location Services from consuming power? That's the only thing I can think of that would be draining the battery to that degree when the app is supposedly dormant. Here's my onStart() where I turn on the location-related stuff and Bluetooth: @Override public void onStart() { super.onStart(); if(D_GEN) Log.d(TAG, "MainActivity onStart, adding location listeners"); // If BT is not on, request that it be enabled. // setupBluetooth() will then be called during onActivityResult if (!mBluetoothAdapter.isEnabled()) { Intent enableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); startActivityForResult(enableIntent, REQUEST_ENABLE_BT); // Otherwise, setup the Bluetooth session } else { if (mBluetoothService == null) setupBluetooth(); } // Define listeners that respond to location updates mLocationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, GPS_UPDATE_INTERVAL, 0, this); mLocationManager.addGpsStatusListener(this); mLocationManager.addNmeaListener(this); } And here's my onDestroy() where I remove them: public void onDestroy() { super.onDestroy(); if(D_GEN) Log.d(TAG, "MainActivity onDestroy, removing update listeners"); // Remove the location updates if(mLocationManager != null) { mLocationManager.removeUpdates(this); mLocationManager.removeGpsStatusListener(this); mLocationManager.removeNmeaListener(this); } if(D_GEN) Log.d(TAG, "MainActivity onDestroy, finished removing update listeners"); if(D_GEN) Log.d(TAG, "MainActivity onDestroy, stopping Bluetooth"); stopBluetooth(); if(D_GEN) Log.d(TAG, "MainActivity onDestroy finished"); }

  • Designing for varying mobile device resolutions, i.e. iPhone 4 & iPhone 3G

    - by Josh
    As the design community moves to design applications & interfaces for mobile devices, a new problem has arisen: Varying Screen DPI's. Here's the situation: Touch: * iPhone 3G/S ~ 160 dpi * iPhone 4 ~ 300 dpi * iPad ~ 126 dpi * Android device @ 480p ~ 200 dpi Point / click: * Laptop @ 720p ~ 96 dpi * Desktop @ 720p ~ 72 dpi There is certainly a clear distinction between desktop and mobile so having two separate front-ends to the same app is logical, especially when considering one is "touch"-based and the other is "point/click"-based. The challenge lies in designing static graphical elements that will scale between, say, 160 dpi and 300+ dpi, and get consistent and clean design across zoom levels. Any thoughts on how to approach this? Here are some scenarios, but each has drawbacks as well: * Design a single set of assets (high resolution), then adjust zoom levels based on detected resolution / device o Drawbacks: Performance caused by code layering, varying device support of Zoom * Develop & optimize multiple variations of image and CSS assets, then hide / show each based on device o Drawbacks: Extra work in design & QA. Anyone have thoughts or experience on how to deal with this? We should certainly be looking at methods that use / support HTML5 and CSS3.

  • Reasons for Ajax navigation breaking on Coldfusion/Apache when running an app in iOS fullscreen mode? [closed]

    - by frequent
    Not sure if this belongs to SO or here. I'm running a webApp using jquery, jquerymobile, requireJS and apache, coldfusion8, mysql 5.0.88 serverside. The app works fine until I try to run it in fullscreen mode on iOS (add icon to homescreen, launch app from there with <meta name="apple-mobile-web-app-capable" content="yes" /> specified). This meta tag will break the Jquery Mobile AJAX navigation. The AJAX request will fail and the requested page will be loaded as a new page, thereby restarting the app on every page change. I have chased this through the whole front end starting from requireJS through Jquery Mobiles AJAX navigation down to the AJAX request being made in Jquery. xhr.send( ( s.hasContent && s.data ) || null ); In regular browser this works no problem. In fullscreen mode, this fails (readystate=0, empty response). I have found this article, which argues that fullscreen mode is like a browser instance with different HTTP strings. On ASP.net this results in the browser not being identified by the server and only basic browser settings being assumed (e.g. no Javascript). I'm a little lost where to start looking for possible reasons serverside. I have not written any server code for handling Ajax page navigation, so this must be something that is handled out of the box by Coldfusion or Apache? Question: Where could I start looking for problable causes of fullscreen mode breaking AJAX navigation if I assume Coldfusion or Apache are the culprits? Is there a setting I'm missing in httpd.config? What else could be the problem? Thanks for inputs!

  • iPhone app works hundreds of times, then crashes from memory error on startup, then never works unti

    - by peter
    I have a Cocos2d/openGL iPhone game. It's a universal app and I'm dealing with an occasional but nasty error on the iPad. We are loading a lot of textures up front (3 2048x2048 textures). I'm working on reducing this up front load, but what worries me is I really don't understand the root cause of this crash that permanently breaks the app. This is the deal: 1. App works fine for hundreds of plays on the iPad 2. Eventually (I'm guessing due to other programs using up some memory and not letting go or whatever) the app starts crashing on startup. It just closes again in the middle of loading. 3. The App will now never work again on that iPad, closing immediately every time, until the iPad is restarted. Obviously my app is demanding too much memory up front to work reliably every time, I get that. What I don't get is why when it fails once, it has failed forever until the iPad is restarted. Can anyone explain what is going on here? EDIT: forgot to add organizer crash lags just say low memory, like this every time (I changed my app name to MyAppName below). Again, I know it's low memory, but why does it stay low memory until restart?: Incident Identifier: E7A2507C-3FB1-4E3B-B315-09F094236541 CrashReporter Key: 0fda9d667f2c6073f20a76809aa25438b6854d15 OS Version: iPhone OS 3.2 (7B367) Date: 2010-04-30 16:59:44 -0400 Free pages: 437 Wired pages: 17228 Purgeable pages: 0 Largest process: MyAppName Processes Name UUID Count resident pages MyAppName <6307ce41802850944baa78d29224fa7f> 22385 (jettisoned) (active) mediaserverd <ea8bac28b06fe3980fdd44b5caceb563> 242 DTMobileIS <a0f651e43881e66f50f8a95abea72921> 5826 notification_pro <4c9a7ee0a5bbe160465991228f2d2f2e> 67 syslog_relay <4ceaed776d2df957fa130712f4ef21d0> 66 notification_pro <4c9a7ee0a5bbe160465991228f2d2f2e> 67 notification_pro <4c9a7ee0a5bbe160465991228f2d2f2e> 67 afcd <4f3c9566e33b4463f05603d990584e5d> 72 ptpd <83de0f774bd6553d513ae9e19b0f9b56> 181 syslogd <66247e305d5c0bf6f1ce1cc950653263> 81 lsd <a4d852c1c8da2b3d231bdc90887b52ba> 130 iapd <a8534cbde4b90ad5915dd26ab03ff3e3> 204 notifyd <5e9d5bee7c3eae1c8b494c79eb11406e> 71 BTServer <64e4a6ea6b1240db2331e05a29caa862> 108 CommCenter <97bf297944ac4bde19bcee96dd23bd5f> 181 SpringBoard <c7a5904c12db7b14334a4edaa4cabaa9> 5339 (active) configd <aca9fa3380322669164fd6b1a3864300> 373 fairplayd.K48 <2d997ffca1a568f9c5400ac32d8f0782> 84 locationd <dd1ea88105c62173908ce767db5c4d37> 599 mDNSResponder <820560222d47a1f2a0dce98a7f8a9721> 108 lockdownd <497fd54c79a680bf29f5d9320f514613> 303 MobileStorageMou <c277b79c2157c4dc5cfc5c3ca35bd5f2> 69 launchd <66972eee4d865c4383b33d985d22994b> 98 **End**

  • How to convert from amateur web app developer to professional web apper?

    - by Nilesh
    This is more of a practical question on web app development and deployment process. Here is some background information. I use PHP for server side scripting, javascript for client side. I use Netbeans and notepad++. I user Firefox and firebug for debugging and testing. The process I use is very amateurish, I code something in netbeans, something in notepad++ and since there is nothing to compile, I just refresh the firefox browser and test it. This is convenient and faster compared to the Java development enviornment where you would have to atleast compile and deploy the jar files before you could run them. I have been thinking of putting a formal process in my development and find it hard putting it together. There are so many things to do before you can deploy your final web app. I keep hearing jslint, compression, unit testing (selenium), Ant, YUI compressor etc but I am now looking for some steps that I can take to make me more organized. For e.g I use netbeans but don't use any projects within it. I directly update the files. I don't use any source control but use my Iomega backup that saves each save into a different version and at the end of the day I backup the dev directory to my Amazon s3 account. For me development environment is just a DEV directory, TEST is my intermediate stage and PROD is the final directory that gets pushed out to the server. But all these directories are in the same apache home. I have few php scripts that just copies the needed files into the production directory. Thats about it for my development approach. I know I am missing the following - Regression testing (manual or automated ??) - automated testing (selenium ??) - automated deployment (ANT ??) - source control (svn ??) - quality control (jslint ??) Can someone explain what are the missing steps and how to go about filling those steps in order to have more professional approach. I am looking for tools with example tutorials in streamlining the whole development to deployment stage. For me just getting a hang of database, server side and client side development all in synchronization was itself a huge accomplishment. And now I feel there is lot missing before you can produce quality web application. For e.g I see lot of mention about using automated testing but how to put in use with respect to javascript and php. How to use ANT for the deployment etc. Is this all too much for a single or two person development team? Is there a way to automate all the above so that I just keep coding in netbeans and then run a batch file that is configured once and run it everytime to produce the code in the production directory? Lot of these information is scattered on the web and here, if someone can guide I would be happy to consolidate here. Thank you for your patience :)

  • Antenna Aligner Part 5: Devil is in the detail

    - by Chris George
    "The first 90% of a project takes 90% of the time and the last 10% takes the another 200%"  (excerpt from onista) Now that I have a working app (more or less), it's time to make it pretty and slick. I can't stress enough how useful it is to get other people using your software, and my simple app is no exception. I handed my iPhone to a couple of my colleagues at Red Gate and asked them to use it and give me feedback. Immediately it became apparent that the delay between the list page being shown and the list being drawn was too long, and everyone who tried the app clicked on the "Recalculate" button before it had finished. Similarly, selecting a transmitter heralded a delay before the compass page appeared with similar consequences. All users expected there to be some sort of feedback/spinny etc. to show them it is actually doing something. In a similar vein although for opposite reasons, clicking the Recalculate button did indeed recalculate the available transmitters and redraw them, but it did this too fast! One or two users commented that they didn't know if it had done anything. All of these issues resulted in similar solutions; implement a waiting spinny. Thankfully, jquery mobile has one built in, primarily used for ajax operations. Not wishing to bore you with the many many iterations I went through trying to get this to work, I'll just give you my solution! (Seriously, I was working on this most evenings for at least a week!) The final solution for the recalculate problem came in the form of the code below. $(document).on("click", ".show-page-loading-msg", function () {            var $this = $(this),                theme = $this.jqmData("theme") ||                        $.mobile.loadingMessageTheme;            $.mobile.showPageLoadingMsg(theme, "recalculating", false);            setTimeout(function ()                           { $.mobile.hidePageLoadingMsg(); }, 2000);            getLocationData();        })        .on("click", ".hide-page-loading-msg", function () {              $.mobile.hidePageLoadingMsg();        }); The spinny is activated by setting the class of a button (for example) to the 'show-page-loading-msg' class. Recalculate This means the code above is fired, calling the showPageLoadingMsg on the document.mobile object. Then, after a 2 second timeout, it calls the hidePageLoadingMsg() function. Supposedly, it should show "recalculating" underneath the spinny, but I've not got that to work. I'm wondering if there is a problem with the jquery mobile implementation. Anyway, it doesn't really matter, it's the principle I'm after, and I now have spinnys!

  • The State of the Internet -- Retail Edition

    - by David Dorf
    Over at Business Insider, there's a great presentation on the State of the Internet done in the Mary Meeker style.  Its 138 slides so I took the liberty of condensing it down to the 15 slides that directly apply to the retail industry.  However, I strongly recommend looking at the entire deck when you have time.  And while you're at it, Business Insider just launched a retail portal that's dedicated to retail industry content.  Please check it out as well.  My take-aways are below after the slide show. &amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;quot;&amp;amp;amp;amp;gt;&amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;gt; [Source: Business Insider] Here are a few things I took away from the statistics: Facebook and Twitter are in their infancy.  While all retailers should have social programs, search is still the driver and therefore should receive the lions share of investment.  Facebook referrals are up 92% year-over-year, but Google still does 80% of the referrals. E-commerce continues to grow at breakneck speed, but in-store commerce is still king. Stores are not showrooms yet.  And social commerce pure-plays like Gilt and Groupon are tiny but worthy of some attention. There are more smartphones than PCs on the internet, and the disparity will continue to grow. PC growth will be flat and Tablet use will continue to grow. Mobile accounts for 12% of all internet traffic. A quarter of smartphone sales come from China, so anyone with a presence there better have a strong mobile strategy. 38% of people have used their smartphone to make a purchase, and many use their smartphones inside stores.  Smartphones are a critical consumer tool for shopping. Mobile is starting to drive significant traffic to e-commerce sites, especially tablets.  Tablet strategies are crucial for retailers. Mobile payments from the likes of Paypal and Square are growing quickly.  It will be interesting to see how NFC plays in this area. Mobile operating systems are losing market share to iOS and Android.  I wonder in Microsoft can finally make a dent? The internet is being dominated by mobile devices, and retailers had better have a strong mobile strategy to meet consumer demand.
