I want to learn mobile programming, specifically Android or iPhone programming, but not sure if it is necessary to learn J2ME before working with Android or iPhone. I know only core Java (and OOP concepts very well).

I consider myself an Android developer, after having created four apps and learned a lot by creating them. Now I've begun my venture into the iPhone app development world, and I don't remember the Android learning curve being this extreme. It doesn't help, though, that I was very familiar with Java and Eclipse whereas I hardly even know how to use OS X. I learn fast and I know exactly what I want to make, I just need the means to get there. I'm really floundering with Xcode and the new project templates (of which there are several, and I hardly know what they mean). I know there are many books and things out there for starting from scratch but I feel like my Android knowledge should count for something. Is there a good resource for learning the basics of iPhone development, given that I am quite familiar with the Android platform? I'm looking for anything that converts Android knowledge to iPhone knowledge; a table of UI element names in each platform, or of concept equivalents, or a compare/contrast of the frameworks involved, or anything that will increase the rate of learning given that I know the Android platform already.
View 2 Replies View RelatedI have been tasked with updating my teams dev. environment. This environment will be used to develop and test J2ME and Android mobile applications. I am looking at NetBeans 6.8 and Eclipse 3.6. Do you have any recommendations for why either of these would be good or bad for this? (aka mobile plugin problems, compatibility issues, ease of setup/maintenance for team members, high quality mobile dev. support, etc.)

Would you please compare between J2ME VS Android VS iPhone VS Symbian VS Windows CE. I would like to know which one is better, and if there is any VM technology to test the programs. Which one should I choose and why? Is there any IDE, debugging facilities?
View 11 Replies View RelatedIs there a way, apart from using HTML and JavaScript on a web control, to have an (almost) single codebase for an application that should run on iOS and Android?The big issue is of course that they use a different language (Java for Android, Objective-C for iOS) for application development. It would be nice to have some sort of meta-language that will be translated in Java and in Objective-C.What about Flash? Adobe wasn't supposed to release a tool to create flash-based apps in iOS?
View 5 Replies View RelatedI am entering mobile development. I have been working primarily in .NET since 1.0 came out in beta. Before that, I was mostly a C++ and Delphi guy and still dabble in C++ from time to time. I do web apps quite a bit so I am reasonably proficient with Javascript, JQuery and CSS. I have also done a few Java applications. I started web programming with CGI and live mostly in the ASP.NET MVC world these days.
I am trying to decide on which platform/OS and tool to select. I am concerned with the size of the market available for my applications as well as the marketibility of the skills I will pick up.
The apps I have in mind would work on both phones and pads. Some aspects of what I have in mind will play better on the bigger screens that will be available on pads.
Here are the options I am considering:
Apple iPhone/iPad using pure Apple SDK (Objective-C)
Apple iPhone/iPad using Mono Touch (C#)
Android using pure Android SDK (Java)
Multiple platforms using something like Titanium to generate native apps from web technologies (HTML, CSS and Javascript)
Multiple platforms using HTML5 web applications that run in the browser (HTML, CSS and Javascript).
I would like to ask all of you if you know any good books, articles etc ... on development for these mobile platforms. I'm looking for learning material where the whole technology, OSes and development is discussed in great detail so i could gain a deeper understanding of the system as a whole.

I'm not a complete beginner as I have programmed in quite a few languages, with my current focus on PHP and Drupal development, but I have not developed for either the iPhone or Android before.
I have downloaded the respective SDKs, but I was hoping to find some good quality tutorials that with step-by-step guides getting your development environment up and building your first app.

View 6 Replies View RelatedCan anyone recommend a good Beginner Android programming book? When I was in college about 20 years ago I used to program a lot (Basic, Pascal, COBOL, Fortran). I dabbled a little bit in VisualBASIC about five years go, but it was really a hack. Now, I really have a burning desire to write some applications for my Android phone, but I really don't know anything about all the new programming technologies (OOP etc). I'm looking for a good book that will teach me modern programming using Java and the Android platform.
I've seen good books on learning Java 6 and some good books on programming Android (but they all seem to assume you know Java or C), but nothing that seems to combine the two. I'd really like to learn Java right on the Android platform to begin with if possible. I know there are a lot of resources available online but unfortunately much of the time that I will spend on this endeavor is when I won't have internet access so a good book would go a long way.
Why is support for OpenGL lagging so far behind with Android? I have ebooks that date OpenGL 1.0 ES back to 1997 or so. I don't understand why ~13 year old technology is what's being offered in the Android API. Could someone enlighten me? What's the best path for someone wanting to learn OpenGL ES 1.0? The ebooks I have are of course not oriented for Java/Android and most everything in them doesn't work when I try it. I can post some specific examples later but at this point I'm just wondering if I'm wasting time or if I should keep going and struggle through it. I have a tiny amount of OpenGL experience but it's with 2.0 and apparently things were very different back in the ES 1.0 world. I guess my question boils down to, is OpenGL ES 2.0 support coming to Android anytime soon? And what OpenGL ES 1.0 + Android learning resources already exist?
View 10 Replies View RelatedI have some knowledge about Human computer interaction and some basic knowledge programming scripts (Python) that run from start to finish and automate some tasks I want to do or calculations. In the past I built interfaces in HTML with PHP behind it. I would like my python scripts to evolve from the command line and build some applications with GUIs that would allow the user to drag files and push buttons to initiate operations and check progress graphically. Since I write my scripts in Python I looked at some of the options (Tkinter, wxPython, PyQt) but I can't make a decision between them to invest my time learn one and not the other. My criteria: Has a introduction for programmers for GUI (what are the differences from a script, examples of some simple interfaces). A framework that would allow me to run my programs on the platforms I use most (Windows) but that can also run on Mac and maybe Linux, without too much modification. If not the same, similar to how you program GUI for Android and/or Nokia smartphones. I'm planning to write some programs for these platforms in the near future so I would like to carry over some of the lessons here onto those platforms, if possible. I did find this previous question but none of the answers are satisfactory. Does any of the frameworks fit these requirements better than the others or are they essentially similar and I would be happy with any of them?

View 3 Replies View RelatedI am interested in getting my feet wet in PDA/mobile development.The only two drivers for me are the drive to learn cool (or at least, new) stuff, and may be to code some app that I felt I really needed but lacked. As such, I would like to know what the comparative benefits/downsides would be for me as a developer in choosing one of the three platforms (iPhone vs Palm Pre vs. Android.I will have access to any of the 3 but not to Windows mobile).This is not a duplicate of this question, since I do not care at all about that question's data points (cost of the handheld, popularity of the platform). Also, just to be clear, my goal is not financial at all - I don't plan to make money off of such development nor directly use the skills in the area I might obtain in my career (e.g. I work on stuff that has zilch mobile exposure and will remain so). So concerns such as "installed user base" are pretty irrelevant. All I care about are tangible (learning) and intangible (sheer joy of it) benefits to me as a developer.Also, please be positive and don't put down other platforms or otherwise use this as a holy platform war excuse. I have edit privileges and will mercilessly edit any un-backed-up-by-facts attacks on any platform that aren't downvoted.
View 8 Replies View RelatedI am a newbie to Android and the Eclipse development environment and would like some advice on best practices for debugging my apps when they throw a Force Close.I have researched ADB, however, I can not get this to interact with my phone even though I have explicitly turned debug mode to true on my test handset.Obviously Android comes with a LOG method which I have seen utilized in many example apps, can someone please explain how to review these logs quickly and how to setup logging appropriately to determine the cause of a Force Close (always occurs when I push the Home button).Any advice on debugging effectively in Eclipse would be much appreciated!

View 3 Replies View RelatedFor my useless project of the month I'm working on a 'emulator' to run J2ME programs on Android. But now I'm stuck with the J2ME Sprite implementation. Specifically the transformations used in it.
In my Sprite I have a bitmap with three character images. I would like to paint the second frame mirrored or rotated 90 degrees. What would be the best way for it?
I have following code that paints the given frame without any transformations.
frameX, frameY are frame position coordinates on give sprite bitmap.
Rect src = new Rect(frameX, frameY, frameX + spriteWidth, frameY + spriteHeight);
Rect dst = new Rect(paintX, paintY, paintX + spriteWidth, paintY + spriteHeight);
canvas.drawBitmap(image, src, dst, null);
As I understand I need to make some matrix magic on the canvas, but I have not been able to figure this out.
