Android :: Lightweight Cross Platform C GUI (OpenGL)
Nov 4, 2010
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.

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 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.

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 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.

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?

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.

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.

Single Threaded OpenGL game ! (check bottom, you can download and use the helper class) Lighting disabled ! Depth Buffer disabled ! Culling enabled ! Textures disabled !
Just 176 integers (x,y values only) making 88 vertexes along with 132 index numbers making "44 triangles only"
Framerates I get is
with GL_BLENDING disabled - 145 fps approx only! enabled - 110 fps approx only!
I have the screenshot of exact code in the draw function here.. just 2 damn lines ! I have hidden only the comments.. click here to see it http://prasna991.googlepages.com/drawframe.png
variable details in the 2 lines of code =========================== ipts = 176 elements (only x and y for each vertex) totallinetriangles * 3 = 176 lineindexes = 132 elements - type "short"
Here is the screenshot of output drawing and how it will look like http://prasna991.googlepages.com/screen.png
OpenGL single threaded Initialization Helper ================================ Here is my OpenGL helper class.. makes the OpenGL initialization for newbies a cakewalk http://prasna991.googlepages.com/OpenGLHelperclass.txt
I tested by rendering on the touch event only.. frame rate drops only when u touch and drag and here I have just tested by tapping and releasing gently on the emulator and on the device
Is this the device limitations ? So graphics is actually a lot lot lot slower than on iPhone ?

I would like to be able to use the OpenGL API from both Java and C (via NDK).
In Java, there is a GL object passed, which has all GL methods on it.
In C, you just talk to the native library.
In a single onDrawFrame callback (for which Java is passed a GL), can I use methods on the GL object, and also call NDK methods which access the openGL library?
In other words, is the GL object just a wrapper for the same instance of the native library?

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 ?

It is clear that cross compilers will not be allowed by the Apple App Store, so a developer will need to be familiar with Objective-C to create applications for the iPhone.I was wondering, is there a cross compiler that will take Objective-C application code and rebuild it into a similar Java application that can be packaged for Android? That way, a developer could still learn just one language (obj-c) but put out applications on many devices.I understand that the Java port would be less optimal than a natively coded application, but could conceivably save a developer some time.

The behavior of XMLHttpRequests in Android is very odd when doing cross domain requests. The browser should either fail with an error and not perform the request, or it should follow CORS (http:// www.w3.org/TR/access-control/) and start with an OPTIONS request to the remote domain. The Android browser (2.1 and 2.2) instead performs the request, which is received by the remote server (and this is the dangerous part both for data leaking and remote attacks), but the response is not set in the javascript (status of 0 and responseText null)

Is 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?

I need compiling a lib (ODE) for android - problem is it uses automake and I can't seem to find any decent documentation/how to cross compile a static/dynamic lib for android.
BTW, I'm using ubuntu 12.04 as a dev environment (latest up-to-datest SDK and NDKs are installed) and I have no problem with making the wrapper library - just need to get the static (or dynamic) lib built.

I want to use somthing like: MyLogger.e("MyApp","I have an error.");
In a cross-plattform project, where MyLogger should be static to make it available in the whole project.
So I was trying something like:
CODE:.........
The compiler complains about the static. How do I do this? Is it possible at all? If not, what's the right approach?

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?
