Android :: Developing Cross Platform Mobile Application
Jul 30, 2010
More and more mobile platforms are being launched and sdk's are available to developers. There are various mobile platform are available,Android,iOS,Moblin,Windows mobile 7,RIM,symbian,bada,maemo etc.
And making of corss platform application is headache for developers. I am searching common thing across the platforms which will help to developers who want to port application to all platforms.Like what is the diff screen resolution, input methods, open gl support etc. please share details that you know for the any of platform . or is there possibilities , by writing code in html (widget type of thing) and load it into native application. I know about the android , in which we can add the web view into application. by calling setContentView(view)
Please share the class details where we can add the html view into native application of different type of platforms that you know.
Purpose of this thread is share common details across developers. marking as community wiki.

I need as simple as possible solution for uploading files (eg. photos) to my website from mobile devices (iPhone, Android, BB, Nokia). Is it possible to do it in same way? Using Java or XHTML?

I am a C++ programmer interested in developing applications for Android as well as the iPhone platform. I have explored both these platforms by writing simple applications in Java (Android) and Objective-C (iphone). But the fact is that I am not comfortable with either of these languages, and it bothers me that I have to write 2 very different versions of the same application to support both platforms. (And then what do I do to run it on a Nokia phone?)Is using web technologies (JavaScript/HTML/CSS) a viable solution for writing apps which will run on multiple mobile platforms? I have heard of Appcelerator and PhoneGap, but I am not sure how mature these products are. I'd appreciate any feedback from folks who have used web apps as a solution for developing cross platform mobile apps.

Is there any decent application for cross platform instant messaging? My wife has an iPhone and I have a Samsung Captivate.I really don't see the point in using SMS to send quick messages back and forth while I'm at work or wherever when we could easily use some IM client.

I am trying to install Android on Beagleboard (TI's OMAP35x chip). They have provided toolchain to build the OS and port it on the chip. Now the next question is developing Android apps. I am interested in knowing about the Java SDK for android. So can I use the standard SDK provided by google, so far I cannot find any SDK provided by TI for Java.Putting it in simple terms, will an application developed on standard Android SDK work on beagleboard.

We have a desktop/web java application and also getting into Android development.Ideally we would like one app that runs both on desktop and android.From what we can tell, it's not much possible to run normal java apps on android. But wondering if it can do it the other way? That is, run android apps easily on the desktop (without the user install the sdk or android emulator)?In a prefect world we'd like one app for both platforms. Realistically though it seems like we're going to have to have one app with two front ends?

I'm looking for a way to collaborate on a "note" with a friend of mine on a Palm Pre. In our case, we want to maintain a collection of quotes together. It'd be nice if we could maintain updates in the same place and have them be in sync. Not necessarily looking for an "app," but a mobile site that would let us accomplish this would work as well. Does anyone have any ideas?

I am looking for a lightweight cross platform GUI library for different signal-processing applications. An ANSI-C program must be statically linked with it and the size matters. A finished application must have the same look on any platform like iPad, iPhone, Android, Ubuntu, Leopard, Windows, etc.Qt is not appropriate, because it is C++, too big, and doesn't work on iOS devices. I lean toward OpenGL-based GUI library, because OpenGL is supported by every modern target platform and an OpenGL application will have the same look and feel on every device. Preferably, such GUI must support forms definitions using the declarative semantics, e.g. from C strings or from external textual files.

I have a Bluetooth service that I programmed for .Net on a Windows machine and I would like my Android 2.1 phone to connect to it. The server is listening for the same UUID which the Android is using to connect. But the connection is failing.When I try to connect to devices that are not listening for that UUID, I get an exception with the message "Service discovery failed", but when I try to connect to the server that is listening for the right UUID a message box pops up saying:"There was a problem pairing with bluetooth device."And I get an exception with the message "Connection timed out." So it looks like the server and the Android are communicating, but there is some sort of failure during handshaking. I know that the Android requires that the server is paired with the phone and also encrypts the communication channel. Does anyone know which specifications are used to do this? I would love to get my server to respond properly to the connection attempt.

For example, I just purchased an HTC One which is running the very latest Snapdragon S600 chip and Adreno 320 and I'm comparing it to the iPhone 5 (A6 and PowerVR SGX543MP3).
Here are a few applications (mostly games) that I've tried on both devices:
* Fruit Ninja - Touch input is delayed by about half a second on the HTC One but instant on iOS.
* Simpons Tapped Out - The voice sometimes stutters and moving buildings just isn't as fluid as iOS.
* Browser (Chrome and Android default) - Scrolling isn't as smooth.
Like I said, I'm honestly not biased one way or the other but this is just what I have noticed. The iPhone 5 has a much lower resolution but I've also had similar results on the iPad Mini (1024x768 resolution).
Does every application written for Android need to optimized for every individual CPU and perhaps these applications weren't optimized yet?

Most of the time I write code for embedded modules or small programs on my computer to analyze data that said code generates.Now I've been asked to prototype a mobile application to analyze/display that data instead.I have no (6-year old CS101) experience with either of the popular languages (Obj-C/Java?), let alone with any of the APIs/libraries available on the 4-5 popular mobile OSs, so I'm more or less at square one.Adapting the embedded hardware to talk to a phone is fairly straightforward, just add a Bluetooth module that I can configure to emulate a serial port (using SPP profile), but I don't know where to start on the other side.What sort of mobile OS/device should I target for ease/speed of developing a Bluetooth serial port profile (SPP) application from having equal (no) experience on them all?

I'm a programmer looking to play in the mobile world. The application I'd like to play with would support my musical hobbies. I suspect a mobile phone with a music player could easily be programmed to support a classical musicians practice sessions. Access to media player APIs without the need to open external apps or do clunky things with files.Adequate access to playback API to create specific notes and beat patterns. As a hobby application, this should not require expensive tooling.I can switch to a new phone to use the application. Bonus points for something that easily ports to a netbook.I will admit I new to the world of sexy phones. I currently use an obsolete voice device with text messaging. I won't revealing my current flavor of programming because learning a new platform is just fine.

iPhone MMOG Pocket Legends To Go Cross-Platform News can be found there. Finally is all I can say.For those who don't want to read it it doesn't list a date that it should be ready by but it does indeed say Android will be one of the platforms they are porting to.

Id like to create a small cross-mobile javascript application, which consists of a form and a grid as result. I also want to display some images, with something similar to lightbox. I coded an home maded prototype but id like to add 'touch' effects and support multiple screens easyly.I looked at JqTouch but its very slow on my HTC magic/android. Also found XuiJs but cant find any working example.Anyone found something light, nice, and iPhone+Android compatible ?

I have a site which makes SOAP requests to a separate domain using YUI's cross-domain AJAX transport. This is working wonderfully on my site, but unfortunately since mobile browsers don't support flash, I can't get it to work.Does anyone know of a way to make cross-domain AJAX posts on mobile browsers?

I've searched this for like 3 days and I either suck at search or you (yes, YOU) NEEED this.I reckon we need to list ALL the cross-platform multiplayer games out there.That is games that can be played Android vs. iPhone vs. Nokia vs. Facebook etc.The premise here is all my friends have iPhones and Facebook (noone owns a nokia anymore but we'll include it for diversity's sake) and lonely old me sold off my slowPhone/iCrash and now have a Desire - BUT i still want to play multiplayer and i might even get a few to join the revolution when i showcase my superior controls/speed/installynessability etc.

is it viable to develop applications using a stock T-Mobile G1? I guess in contrast to the emulator the real thing is restricted when it comes to debugging.But, is there a simple way to just transfer my self developed, self compiled APK to the phone and install it there? I do not have to go through the market for that, do I? :) Then again I guess it's not as easy as with the emulator, just clicking "Run" in Eclipse - or is there a way to tell Ecllipse to transfer the freshly compiled software to the *locked* phone?Yes, I know I could get an unlocked Dev Phone 1, but, my question is whether this would be *required* or, if not, what my options as a developer are when working with a stock, locked, phone.

I'm beginning to learn mobile programming on the Android platform. I'm up for working with any particular base SDK. I just want to hear some suggestions from the community about what types of applications I should start with to help learn more advanced interactions with the platform.There are of course the Standard Hello World, calculator, etc. But by now I am bored with all of those.What do you all make when learning a new language?

I am planning to develop a game for all of the mobile platform and have pretty much zeroed down on the concepts of the game. but the only issue I'm facing as of now is that I have no idea what would be the best libraries + 3d Engine to us to achieve the best results on the hardware on some of the upcoming mobiles. I'm talking about the iPhone 3GS, the new WinMo and Android devices with the famed Snapdragon, other processors from Samsung, ARM, Qualcomm and even Intel and AMD.as of now i plan to use the ogre libraries for now, but then what will offer portability?? This is much more of a design question rather than just coding. Any help is appreciated, others who wish to collaborate are very much welcome too. just drop me a mail.

I've some files stored in a SQL database. When a user visits a url with the given ID, the BLOB data is retrieved from the database to the webbrower However, the iPhone (Safari) can't download a *.txt and *.doc file. It says: "Safari can't download this file". A pdf can(!) be downloaded and viewed.On Android none of the files can be downloaded.Is this because the iPhone and Android just can't handle all files? Or am I doing something wrong in the Response.

I am interested in implementing an Augmented Reality application for mobile phones using Adobe Flash Platform.
Can you please let me know if any sources is available for me to find out how to start? I'm not sure what software I need to use to implement AR but as I can understand I need: ARToolKit Marker Generator to create the marker matching with the 3D image, then FLARToolKit to analyze the image from the marker and Papervision3D to create an object that shares that same space with the marker. Can you please let me know if what I wrote is correct and advise me how to start the implementation on Adobe Flash platform?

Would it be possible for me to build an application that enables people to encrypt call coming to me with my public key and then for me to decrypt the call data at my end using my own private key. This way I basically have a more secure communication channel which I am assuming because RSA is hard to crack would be difficult to monitor.I am asking this question from a research point of view and have absolutely not considered the factor as to how computationally feasible would such an application be. I would just like to know if there is a way for me to intercept my outgoing data using any built functions.

I'm a junior iphone developer and got familiar with developing on xcode on top of Mac OS.I wanna build some Cross-Platform apps in the near future and wanna Use Ubuntu as my Operating system.I found many solutions that run only on Mac OS or need mac to build apps for iphone but this is not what i need. i need something which can keep me far from mac (for some reasons).I heard about AIR packager for iOS and that also AIR does apps for android but i'm not a flash guy (but can learn if it will do the job), so i wanna guidance from experience people like you about what is the suitable route should I take.

I 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.
