[Q]Where to find any OpenGL ES 2.0 sample code? - Android Software Development

I'm new to the android system and OpenGL ES. I'm just looking for some code to get everything setup and to attach shaders. Thanks in advance to anyone who can help me!

There is a example in the ndk. Officially es2 is only for ndk, tho I believe someone is working on a java wrapper if that's what ur into.

I most certainly prefer c/c++. I guess I now have a reason to read up more on the NDK. Thank you for the response.

Fwiw google added a java wrapper for opengles2.0 in Froyo. Unfortunately, they forgot to bind 1 or 2 important functions though.

glad im not the only one , that example should be the best for you.
Ive been learning the ndk the last couple of days, i think ive got the hang of it. Once you get through the initial setup it works great.
If you got any questions feel free to .

Would a kindly developer please compile a squeak VM for me..

The sources have been developed in visual c++ 6. I have just edited some of it to make use of the soft buttons on my htc-universal as mouse button modifiers (at least I hope that's what I did!!)
I'm asking for someone to compile it for me as I can't afford to buy the dev tools (hopefully in some distant future, I'll be able to have linux on the phone and develop for free.)
I do not know whether the code can be compiled in visual studio 2005... maybe it would gain performance improvements if it could.
Many thanks in advance
Actually... forget that
...Seems I was directed to old sources... time to start again
"Give man a fish and you fed him for a day, teach him how to fish and you fed him for life…"
Any way here's a link to download eVC++, from MS. It's completely free, plus it looks and feels just like VC 6. With the proper SDK (also free, look for link on that page) you can compile programs for Pocket PC WM2003 and up devices.

Good luck
Thanks
That's fantastic. Thank you very much for pointing me to a free compiler... I didn't know one existed

You can also use gcc.

Re: Thanks
And you can always use eDonkey to download a full VS2005 and not spend any money. Noone would care that you are using a stolen compiler until you'll start selling your programs. Or just ask any of your ex-USSR or chinese friends (if you have them) to share it with you
For example I never bought any computer program at all.

Visual basic for Android

A new development tool is now available for Android devices: Basic4android.
Basic4android syntax is similar to Visual Basic with support for objects.
Basic4android includes a GUI designer that supports multiple screens and resolutions.
I believe that this tool is much simpler to start with than Eclipse + Java.
Compiled applications are regular APK files, and the performance is similar to Java performance.
You can see more information here: basic4ppc[dot]com
Does it have a tutorial or may some one leave a brief training here?
thanks for finding something like this. I've always wanted to create my own apps and now I can and with this program it looks pretty good.

Godsend. I've been self-learning Java this week and slowing developing my first two apps using Eclipse. I've got a good grasp of the language but I was always better with vb.
Thanks heaps
I had Basic4PPC for WM Development, then Android came along. I'm glad the author has released Basic4Android as well!

Looks very promising!! Though I would have liked to see C# instead of visual basic coding. I can't even remember it anymore. It's been so long since I have used visual basic!! Lol. Maybe it's time to study up. I have refused to use have for a number of reasons!

Does anyone have now experiences with that programm? I have an application written in VB for Windows Mobile. I want to change that to Android.
Would be nice to get some information before i buy this tool.
Wow, this looks interesting. Might pick this up
Edit: wow this was an old topic..

It shouldn't be difficult. If you like you can post this issue in Basic4android forums. I'm sure that it will be solvable.
I use mostly b4a, it is very simple and there is a lot of help on the forums, and people developing libraries and code classes.
I am learning on android studio now, but I have been happy developing with b4a!

Getting Started with Android Development

Hey Everyone!
I apologise if this is a thread or question that gets posted often, I had a search around but I couldn't see anything.
Essentially, I'm just looking for some good resources and tips for getting started with Android development. I have looked at a few books and tutorials (and the official SDK documentation, of course) but I was wondering if I'd missed any good one.
The main issue I'm having is that the things I've found so far seem to assume you know quite a bit about Java development. I come from a pretty experienced C++ background so although I'm very familiar with coding in general, I'm not all that hot with Java. Would you recommend sticking with Android and picking it up as you go along, or waiting and doing some pure-java stuff first? In either case, which are the best books/examples/tutorials you guys have found for an android beginner like me that does know a bit about programming (just not java)?
Thanks in advance!
I think the best way to learn is to get an android book and work through the tutorials in order.
Don't just skim read it though, you need to actually type out the code yourself and think about what each line is doing.

Oh absolutely, I'm looking for suggestions for good books, too =)
I found Lars Vogel's introductory tutorials very good when getting started in Android. If you're already familiar with other programming languages, you'll pick up the java needed pretty easily as you go...

I used Reto Meier's professional android 2 book and thought it was pretty good. The most important stuff to learn at the start is how activities and intents work. The other stuff you can kind of pick up from google as you go.
I haven't developed any application for Android (yet). If you want to develop native code applications, you will need the Android SDK and the Android NDK (gcc rules!). This seems to be the installation order. Check the installation instructions for both of them. The NDK contains some examples. As far as I could see, a native application has a java part and a native dynamic linked library (which is called/loaded by the java part). The NDK also comes with documentation. I guess the Android developer gurus may give you more hints about documentation links.
I am interested in getting started with Android Development as well. I have a background with Java, but that was a year or so ago. I'm sure I could pick back up with it pretty quickly.
What books do you recommend?

Planning to learn coding games for android - need help

I would love to create an android game. So I am planning to start learning it.
I have coded an application already and I think I know the basics. So now I want to get into game programming which is too complex if I heard it right.
I would like my fellow developers who have experience in coding games to give me some links and tutorials which will come handy for newbie like me.
Thanks in advance!

I think the best way to learn any new area of software development is to get stuck into a project. I've been working in various embedded and real-time environments for years but a couple of years ago myself and a couple of mates decided to try to make a game. At the time we wanted to learn C# so we dived into the XNA framework & made something that ran on Windows & XBox. It was never released, but I learned a lot of new stuff. Started with their tutorials and went from there. I can't help with links and so on for Android but don't be put off by the idea that games are too complex - the first software job I ever did was on a full size submarine simulator for the Navy & that really was complicated!
I think that this is a very good piece of advice: http://www.raywenderlich.com/12065/how-to-create-a-simple-android-game
It helped me very much.

When I started to learn android game developing I found some very useful tutorials at: obviam.net. Look for the series 'Getting started in android development with libgdx'.
This series uses the framework libGDX, which enables you to write your game once and easily port it to many different platforms.

I totally support this. I created my first Android game (Rock Ninja) with no previous game development experience thanks to the awesome Libgdx framework/community.
Yeah, LibGDX great thing and very easy to learn on GoogleCode's wiki page by simply reading topics one by one. Of course if you are familiar with java first
I'm also member of libGDX community, even helped to fix some bugs in particle editor. But after deeper look at this engine, you find some problems in deployment on other platforms. So, I'm looking at the Unity 3d now, besides it became free for android and iOS version.

True, iOS is still work in progress with Libgdx. Good news is that the new RoboVM backend(that will replace Monotouch/Xamarin) is looking really promising and a first app has already been successfully published to the Appstore.
I have a decent stash of books on mobile development. I would start with either monogame, libGDX(provided you know openGL), AndEngine, Unity3D, or use cross platform tools that turn HTML5/CSS3/Javascript into native code. Give me a PM if you need anything, best of luck :good:

You don't need any knowledge of OpenGL for Libgdx, everything is abstracted out for you.

Internally yes, but it's abstracted by the framework for you not to need to worry about it.

Best Way To Learn Java?

So I'm just beginning to try getting into development and saw from several users on here that the first step would be to learn Java, so my obvious question is what's the best way to do that? I have little programming experience. I believe I correctly installed JDK and also have Eclipse and AndroidSDK. A brief but clear explanation pointing me in the right direction would be appreciated. Thank you for anyone who can help.

The first thing you should do is ignore the AndroidSDK for a while !
It's not worth touching a phone before you can at the very least write a few simple Java programs.
Start with a single class that prints some stuff out to the screen and go from there.
Once you are comfortable with the syntax, I'd say you'd need to be able to write a standalone Java program that has, say, 10 classes in it as a first step.

Thanks for the advice! I'd definitely agree that I should be able to read and write at least basic code before putting anything to use, however where should I learn how to write the classes? I downloaded the Headfirst Java textbook because I saw people talking about it and seemed pretty legit. Do you know anything about it or how to go about using it? I can't seem to open the .class or .java files even though I believe I correctly installed JDK. Is there a better place to learn? Thanks for any help you give, clearly I'm new to this, however very interested.

I liked the official tutorials much and I'm sure you would like it too.
Just focus on the concept for a while before proceeding any farther.

Yeah, if you want a book, I can recommend the Head First Java book. That's how I learned it.
You can also have a look at the Vogella tutorials, especially for Android specific things.
One tip: If you learn Java just to be able to develop for Android, skip the UI parts. They are completely different on Android.

In my opinion that depends on how much knowledge of other programming languages you have.
If you already know how to use for/while/do-while-loops and if/switch-conditions, you might want to skip those examples. Do it just if you're sure you don't need them.
I didn't run any of the codes. (Wanted to start with Android as soon as possible. :laugh I learn very well just by reading on programming languages because they are basically all the same. So it's not difficult to learn another language if you already know another one.
However, I ran the examples in the books I used to learn my very first languages (Delphi and Python). I just skipped them for Java.
Decide whether it will be helpful for you. If you're in doubt, run them.
The textbook for JAVA in our college is 'Starting out with JAVA' by Tony Gaddis and its really very good for beginners. Just give it a try.
Just read the tutorials, create a new project and start tinkering around. If you have questions, ask them in appropriate java forums.
