I am a senior IT student working on a mobile application for Android. I have 2.5 months design to complete implementation.App basics:
-Seismographer app
-Record data from accelerator
-Visualize data in a live fashion on a graph
-Connect several phones together via bluetooth/wifi to sync up the data
-Geo-aware application - optional
I have limited java knowledge and mainly specialize in system admin and web development. Given my constraints, is it better for me to use Adobe AIR/Flex/ActionScript to develop this? Or Google SDK/Java would take just as long?I feel like on one hand Adobe is faster, but Java is more straightforward?
I have a client-server multigame suite for PC ("kind of" cross-platform using cygwin), which is developed in Java(game menus and database management), C++ (server side), and adobe Flash (game graphics & interaction).
I have never tried to develop for android, so i have no experience.I am thinking of migrating this suite to google TV. So i would like someone with android experience to give a clue on the following :
1) Is it going to be easy to migrate the Java application to an Android application?
2) What kind of Flash support does Android have? Can it load directly swf applications? Does it have to load swf's through browser?
3) Can i find any kind of performance indexes for google TV hardware?
I am successfully running Bluetooth-SPP applications relying on http://bluecove.org/ that is Java to Java. I do now want to establish Bluetooth-connectivity in an Adobe Flex-application. Anyone has experience, ideas?
What is the best solution for multi threading in flex, I notice if I play a mp3 in flex and do something else at the same time something ends up giving out, either the song stops playing or the UI hangs for about a split second. It doesn't have that fluid response that I am looking to achieve. If possible I would like to call a multi threaded java class to do some of the client-side end back end processing. I just don't know if that is possible.
I am new to web technologies. I along with my friends want to develop a web application. There is one guy in our team who knows Flex technology. I would like to use Java Springs framework at the back end. The web application caters to students a Music school. And for the same reason we chose Flex for UI since the application needs to be flashy and rich in graphics.
The application allows students to create profiles and interact with the teacher. Eventually we want to add Online Music classes feature with online payment gateway integrated. Kindly guide me which are the suitable technologies to use at the back end. Also let me know if SpringFlex with BlazeDS integration is a good combination with Adobe Flex.
Most of the desktop application development I do is in Swing, and I'm curious to hear people's thoughts on using JavaFX and/or Adobe Flex for building desktop applications. Have you had success building desktop apps with these? Or would you stick with Swing for now and use tools to help make Swing development more productive?
I would like to be able to operate a scanner from my AIR application. Since there's no support for this natively, I'm trying to use the NativeProcess class to start a jar file that can run the scanner. The Java code is using the JTwain library to operate the scanner. The Java application runs fine by itself, and the AIR application can start and communicate with the Java application. The problem seems to be that any time I attempt to use a function from JTwain (which relies on the JTwain.dll), the application dies IF AIR STARTED IT.[code]
Is it possible to load a .properties file from a client computer using adobe flex? I have a flex app that needs to access a server and multiple URLs but the URLs may change frequently. So I think modifying and loading the URLs from a .properties file would be the easiest way update the URLs
I was able to use florians suggestion and I've added the code below if anyone else is interested. I used the example here URLLoader.
public function URLLoaderDataFormatExample(event:Event):void { var request:URLRequest = new URLRequest("file:///c:/temp/prop.properties"); var variables:URLLoader = new URLLoader();

I would like to learn Adobe Flex mobile development.I have created a new project called SampleProject, then I got SampleProject.mxml in default package and SampleProjectHomeView.mxml.[code]How can I call the add and sub methods from the class above in SampleProjectHomeView.mxml?
I am preparing a document for a project. The project's backend is developed in Java, frontend is adobe flex. I am not sure about the correct way of describe the project in Model-View-Controller way.
For Model layer: Using Hibernate Java beans to implement all the business logic and persistence? For View Layer: Using Adobe flex send post or get request to Controller layer, and get respond in XML format. For Controller Layer: Using Java servlet to handle requests from Flex client?
I've been porting a Flex 4 codebase to iOS using the adobe packager, but have run into a snag when trying to package our whole codebase. The packager runs for a while and then throws an OutOfMemoryError - even if I increase the java heap size to 4GB. No single piece of code seems to be causing the problem, as it compiles successfully if I cut out large chunks of code, and I can change which chunks I'm omitting. It might be related to the size of the code itself.I've logged a very detailed bug report with adobe here: ou can package to reproduce the issue, a ruby script that generates actionscript codeto generate that AIRI file, and a summary of all of the things I tried before logging the bug.
Is it possible to use a Facebook session in a Flash to authenticate on Google App Engine? I'm trying to create a Flash game and I want to use GAE as the back-end.
I wanted to put a search box in my flex app that would act just like google or google finance: you start typing and a drop down list just below starts filtering the results dynamically. Does anyone know how to do this in flex? I am using flex and php so as the user types it will pull results off the server dynamically.
I am attempting to add google analytics tracking to an Adobe Air app created with HTML and javascript.I have tried adding the ga.js file and using it like I would in a webpage:
But this doesn't seem to register anything on the analytics dashboard.Have also tried using the GA for flash actionscript library but I can't seem to create an instance of the GATracker as it needs a DisplayObject?
EDIT :using the information from grapefrukt I tried the following:
air.Sprite = window.runtime.flash.display.Sprite; air.GATracker = window.runtime.com.google.analytics.GATracker; var tracker = new air.GATracker( new air.Sprite(), "UA-XXXXXXX-X", "AS3", false );
but I get the following error:TypeError: Error #1009: Cannot access a property or method of a null object reference
I'm using Adobe's Google Analytics SWC library for flex. What I'm trying to achieve is to simply be able to utilize the realtime features of Google Analytics to know when users have my AIR desktop application open.Making it detect an open application was easy enough. I can visually see the count on Google Analytics getting updated in a matter of seconds whenever I open up my application. However, the problem occurs when I close my app. Google Analytics doesn't seem to detect a closed app and still detects it as open on the realtime view. How would I go with making Google Analytics know that the application has stopped?
So far, it seems the realtime counter only reverts back to 0 after some 30 or so minutes that I have already closed the app. This leads me to believe that it was considered to be idle by Google and so decided to update the statistics. That might be good and all but I really want to utilize the realtime capability so I need it to reflect when an app closes with only a few seconds of offset.
I tried with flex and java in the backend. In this, I am able to upload files till 100 MB using remote object (blazeDs) where we will read the file as byte array and send it to the java method. If the file size exceeds after that, then I get the run time error in IE.
I could play MIDI file where "filename" is a String type with "asd.mid" value. However, I tried to sent AIR's nativeprocess command to Java, it shown "could not read" error.
I am using Flex 3 and make a call through a RemoteObject to a Java 1.6 method and exposed with BlazeDS and Spring 2.5.5 Integration over a SecureAMFChannel. The ActionScript is as follows (this code is an example of the real thing which is on a separate dev network);
I'm building a Facebook multiplayer game where the client side is in FLEX and the server side is in Java and I wanted to know if there is a guide on how to build the server clients managing system. When I say server clients managing system, I mean a server which many clients will connect to and will be able to choose between tables to join and play or to create their own table, same way as in texas holdem poker.
i am working on a flex+java combined project.My IDE and computer configuration is as follows:
[Code]...
When i make a small change in Flex code (eg, reposition of a button...anything), and run the project on server, it does make any change on output. Actually it depends on my luck... because it makes change in output randomly.what is is happening? tried rebuild, republish, clean , restart server, restarting the IDE, restarting the computer all available feature i could think. Also, i created a simple flex project on IDE and compiled it..... everything is compiled and displayed on output.
Right away i just try to explain my problem: Using BlazeDS i got the following Javaclasses:
[Code]...
Then i got a Flex service class calling BlazeDS and executing the getCategories java method. Since Flash dosn't seem to understand typed arrays, the result from that method which i get back in flex is a simple array of untyped objects (the mapping dosn't seem to work here, even tought the class category exists in flex and has the same properties). thats the first thing. but however, i'm converting the untyped objects manually into objects of the category.as class. the second thing is that categories have child-categories within the java object, which are also ArrayLists of the type category.java. the problem about that: my result event object only contains the first level of categories, looking into them the children are allways null. i dunno why they are empty, since they ARE part of the java object category.
and the third thing (the strangest by fast), you maybe noticed i named the properties of the category.java class strange, like idCat and nameTest instead of simply id and name. why that? because the property names of my flex result objects dont seem to change when i change the java objects properties names (result object properties are named "id" and "name" but the java class object properties are named "idCAT" and "nameTEST"). that it REALLY strange, since if i set the properties, like you see at nameTEST = "TESTNAME" it IS recogniced by flex, only the proertyNAMES dont seem to be recognized at all.
I developed a Adobe Air Application and I discovered that the Mobile I am trying to install the application is not compatible with the Adobe Air's supported devices because this wasn't launched yet.
I have some ideas:
Is possible to change the Mobile Name to fake another device and Adobe Air not refuse the installation? Is possible to convert AIR to Java? s possible to run Air without Java? Abandon Flash and do it in Java or Javascript.
I am newer with flex technology.I am creating a chart using ant file & .mxml in eclipse my 'ant' file executes properly but it gives following error when i opens a .swf file which is created auomatically:
Flex Error #1002: Flash Player 9.0.115 and above is required to support signed RSLs. Problem occurred when trying to load the RSL
I'm coding a web app in flex blazeds and Java. I installed the Eclipse plugins for using WTP mixed project. I'm using flex's server that uses an emulate of tomcat when i ran my flex service the web app got the datas, everythings is ok. the problem is when i copy the project with all files generated by flex in my tomcat or the blazeds's tomcat, it doesn't work, this is becasue i want to implement my app on a server the error is:[code] i don't know why tomcat doesn't find the class of flex.messaging.endpoints.AMFEndpoint that is used for my-amf 'URL...'. all works well in the emulated server that flex has.
