I want to learn Flex. I have some knowledge on Java Enterprise Edition, so the server side scripting is not very hard for me. But for Flex I am kind of lost. Unable to understand where to start. I am reading this Flex Tutorial. The IDE for Flash development is the Flash Builder. Also another SO thread says there is a free version of this software, but I guess the Flash Builder 4.7 Student edition is not free any more. I came to know that Eclipse has a Flex development plugin, but I don't know that, that plugin will serve the purpose.
It would very appreciative if someone give me pointers on the following topics.
Where to start on Flex 4,
Which IDE to use,
How to integrate with Web Service/EJB
Thanks in advance.
Where to start on Flex 4 :
Adobe website is the best place, here are few useful links:
http://livedocs.adobe.com/flex/gumbo/flex_4_tutorials.pdf
http://www.adobe.com/devnet/flex/videotraining.html
http://www.adobe.com/devnet/flex.html
Apart from learning the basics of flex it will be good to learn the mvc frameworks used in flex, such as Caringorm and PureMVC
Which IDE to use: Adobe Flex Builder, they provide 60 day trial license, good enough to learn.
How to integrate with Web Service/EJB : There is something called HttpService in flex using which you can integrate with web services.

I want to build an app in android. I have a sound knowledge of C/C++, but I don't know Java as of yet..!
Do I need to learn java to develop an app in android ?? What does I need to do to develop an app ?
I explored this link http://developer.android.com/training/index.html, but I didn't understand what actually do I need to do to develop an app.
Please help..!
Before starting Android development, you should know these:
1. Basic OOP Concepts.
2. Basic Java.
3. Basic XML.
If you already know these things, then just download JDK (According to your OS) and a suitable IDE (like Eclipse, Android Studio, etc)
And explore the Android Development Portal.
P.S: If you are finding Android Developer's Portal difficult to understand then, you can jump to some nice tutorials and start developing. Here is the list of some nice Android Tuts:
Vogella's Blog
Tutorials Point
Core Servelets
XDA Forum
YES... You'll need to have basic knowledge of XML and Java. And once you are clear with Object Oriented programming with Java, you can start Android Application Development.

I am about to start new Android app considering that Java development is not my strongest side I'd like some advice on where to start. The question is not that much about Android API it's more about the right tools and code organisation.
Should I use template app like Android Bootstrap and are there any other better than that.
How should I organize my code so it makes sense while the app grow.
Any other libraries that might help?
The app would be for downloading music and it'd be free one. There would be a server API that will deliver the content.
In my opinion you should start with a blank project and try to learn Java and understand how the classes in Android work. Using a template is not the best way to learn programming because you can easily get confused and not understand what the code does.
You implement the classic 3-Tier architecture with packages for the Domain, Repository, Controller and User Interface. This way you can stay organized and easily improve on your app.
Read Android forums, documentation and see what libraries do you need to use.
Firstly get stronger on Java development, go through the Java SE tutorial. Then you can take a look at the Android Development Getting Started page.
I'd also recommend you to invest on some good programming book

Are there really any tools out there or sdk's that truly support cross-platform java mobile development, and are worth their weight in code?
I would like to rewrite our mobile application with an sdk that would allow usage on IOS (Ipad and Iphone), Android, and Windows Mobile 5 and 6.
If I am asking for the moon, please let me know.
I am traditionally a c# developer, and just moving into learning Java.
I see many different posts about cross-platform development but I wonder where we are as an industry today on this.
You could take a look to the mgwt or the codenameone framework.
For a server-based app built in pure Java but deployed via pure HTML+CSS+JavaScript: Vaadin. But that means your app requires an Internet connection to run.
Tip: Some folks build a bare-bones minimal native app that simply points a web-browser view directly to your site's URL. This allows you to sell/give your "app" in the App Store while actually building a web app that runs cross-platform.
There is no Java present on iOS. So there is no Java-based development kit to build local native apps across iOS, Android, and Windows Mobile.
Google did announce the J2ObjC project to translate Java code to Objective-C for the iOS. But that does not solve all your problems.
Eclipse Tabris is another option but it isn't free (It isn't costly either).

Dear guys
I am going switch to java , i want to know which development technology is promising for future development of apps , is my choose reliable
My top keys are multi platform , wider community , support of latest technologies like smart devices , ...
Also i am not satisfied with adobe ( flex / air ) i think i totally waste my time due to performance and many issues like server side processing and ...
My Other choose is python
Any word from u could help me
Thanks in advance
Yes Java is suitable for your requirement. Still in Java, you have to choose framework like struts, spring... very carefully. But there are lot of forums and blogs are availables. They will guide you.
For UI, SpringMVC is gaining
more and more supports from the
community. Struts is a bit old.
For the Core Framework, still
Spring Framework. Or you may
want to consider GWTas alternative.
For the DAO, still Hibernate.
For the mobile, Android and
Sencha Touch(EXT-js) are
promising.
Google Apps Engine is also interesting. Supports Java + Python.

i want to develop a big web application in Google App engine, but I don't know which framework to use in order to obtain the MVC Model. I prefer to use Spring MVC, but I read that several problems with GAE. Another option would be to use django with python but I have never used that. What framework or option do you recommend? Are there other frameworks?
Greetings
You should check out web2py -- it's a full-stack Python MVC framework that's very easy to set up, learn, and use. It was designed to run on Google App Engine out of the box, and there's a whole section in the online book dedicated to GAE (there are also other references throughout the book discussing a few special considerations when developing for GAE). There's even a "Deploy on Google App Engine" button in the web2py browser-based IDE (see the IDE demo home page and GAE deployment interface).
Your web2py GAE apps will also be portable -- you can deploy them on other platforms (e.g., a Linux VPS) without changing your code (though you may want to make some adjustments once you're off GAE and no longer subject to its limitations).
If you have any questions, you'll get lots of help from the mailing list.
I've used Stripes on Google App Engine with success and pleasure. It's a simple yet really powerful MVC stack, very easy to learn and use, and with great documentation. I've been able to integrate it with Guide (for dependency injection) and Sitemesh (for page templating). If you're interested, the code for the application I developed is available at http://code.google.com/p/memwords/.
Django is a best framework for projects without incredible high load, but GAE supported by a very old version.
Try to use Pycharm for editing GAE-applications. This is already usable IDE with active development
Take a look at Tornado, it's a scalable, non-blocking web framework in python and it's simpler and easier to develop in than Django.
