View 3 RepliesAs I am one who cannot find any decent Android-based OpenGL ES references, I have decided to start one. You can check it out at http://www.vincepascuzzi.com. As I am not a seasoned GL programmer, any and all comments and/or questions are greatly appreciated!
My mission is to first create an OpenGL version of an application on Mac OS X, and then port to Android. Once the port is done, I go through each program, step-by-step, and contrast and compare how the port was done. I also explicitly point out any and all differences between the two, subtle or obvious.
What tutorials and libraries are available which can help beginners to develop 2D and 3D games on Android using OpenGL-ES? I'm looking for tutorials which can help me learn OpenGL-ES, and I'm looking for OpenGL-ES libraries which can make life easier for beginners in OpenGL-ES.
Since Android is still small, I guess it may be help-full to read iPhone OpenGL-ES tutorials as well, as I suppose the OpenGL-ES functionality is much the same.
I have found the following useful information which I would have liked to share:
Android tutorials: DroidNova: Basic tutorial covering polygons, no textures anddev forum with some tutorials
Other Android OpenGL-ES information: Google IO lecture regarding games, not much OpenGLES The The Khronos Reference Manual is also relevant to have, but its not exactly the best place to start.
iPhone OpenGL-ES tutorials (where the OpenGl-ES information is probably useful): http://web.me.com/smaurice/AppleCoder/iPhone_OpenGL/Archive.html

As for libraries which a beginner might use to get a simpler hands-on experience with OpenGL-ES, I have only found Rokon, which is recently started, thus has many holes and bugs. And it's gnuGPL licensed (at the moment) which means it cannot be used, if we wish to sell our games.
I have a problem on my Asus ME301T tablet with the Play Books app (I'm running android 4.2). Regular text based books work just fine, however, comic books show as blank pages. Sometimes it will load a few pages if I rotate the screen a few times.
I've tried to reinstall the app and redownload the comics without luck. It works fine on my Samsung i9000 running android 4.3.
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?
i can implement the QSB on my app using onSearchRequested() method.i have 4 column in my table. when i was type in the QSB. it will give some suggestions on the Suggestion window. how to do that? searchable dictionary example shows the dictionary provider class to retrive the suggestions. but on that no data inserted. then how they getting the suggestions. can you explain me what are the steps we have to follow or tutorials, sample codes are most thankful.

I am ready to spend some amount on android paid tutorials also if they are worth a look. Please suggest me some study material along with some android paid tutorials, i want the best tutorial since i have many apps in mind to develop :) I have had a look at all the free tutorials and i know how to do some simple stuff like calling an intent, making the layout file, media controller. But i dont have knowledge about the major issues like database connectivity, flinge, adapters, geolocation and stuff. Hence the bottom line.

Is there any good tutorial on creating such kind of menus? I've looked at the "notepad" example in android, it doesn't really help.

Can any body give me some tutorials about operations on the android emulator ?
View 2 Replies View RelatedDoes anyone have any recommendations for a class (online) or tutorial that teaches android programing for dummies? It's frustrating knowing exactly what you want to do and no idea how to do it. Something that uses basic language and explains each line in detail to help a person remember how to do it later. Any suggestions would be great.

If (in Android) you wanted to write an alarm app where the user entered in the time for the alarm by swiping the hours & minutes up and down, what's the easiest way of achieving this? Is it the Swipe or Fling command?
Are there any good tutorials out there for this?
Specifically some that may cater to an experienced developer (C#) but not necessarily familiar with Java/Eclipse?I have seen a couple vids on YouTube but they are either short (not much you can learn in 3mins or patronizing)

View 1 Replies View RelatedI am looking to start a project that will involve the use of soap quite extensively. However... I know nothing about it! I was wondering if the community here could point me towards a few of the choicer tutorials on the net instead of having to wade through countless sub-par search results. And when I say I know nothing about it, I mean I know that its like an online api to some extent, but really that is it.
This would be used in conjunction with an android app, so I suppose I should also ask if android sdk even supports soap/ is this even a valid question? I really am clueless here.
New to Android; very grateful for the help! I tried searching the web and other threads but the words "free", "ebook" and "library" return thousands of results that don't help. Supposedly at my library you can get books in ebook form. The website says they are compatible with my PC, the Nook and the Sony devices. Is there a way to read these on the Android and if so, how is that accomplished? Also, I read that you can read Google books on Android phones, but when I got to Opera on my phone and go to books.google.com/m and click on a book nothing happens.

I am picking these two books because of another popular thread saying I should have an Android book and a java reference but no one mentioned a book for either. I figured I'd go with the highest rated in for each of those criteria.I didn't know if I could ask a question in the same thread about what books so I figured it was better to start a new one.

View 2 Replies View RelatedI've been looking into Android development, and while I understand the concepts, all of the Java stuff goes right over my head. XML is easy to pick up on, but I quickly found out that advanced Android development is simply not possible without a good understanding of Java. I looked at this book and it seems pretty good: http://www.amazon.com/Java-Tutorial-Short-Course-Basics/dp/0321334205. Is this good material for a true beginner, or will it be a little too advanced? I need something that will start out very slowly and explain the concepts, ideas and functions clearly. The last thing I want is a book that's incredibly complex and hard on a beginner. I have absolutely NO knowledge of Java or any coding, so I need to start with the basics. Is Android Java a lot different than regular Java? I know there are some differences, but if I studied regular Java could I quickly relate that to Android? I wouldn't want to read a Java book then get back into Android and be lost due to the changes. With this in mind please recommend me some books. I'm very enthusiastic about Android and have brilliant ideas for applications. I just need the prerequisites for Android before I can go full force.
View 7 Replies View RelatedI didn't see this posted anywhere here and thought it was cool. For those of you that like to read. (I totally copy and pasted this from the Tmobile forum.)Google has launched a mobile version of its Book Search application which gives Android and iPhone users access to over 1.5 million out of copyright texts from authors including Austen, Dickens and Shakespeare. Google has optimised the texts for iPhone and Android handsets, and users will need an internet connection to view them. The texts are separated under handy categories including General Fiction and Mystery, and the service keeps a list of recently viewed eBooks and allows you to bookmark your page.

View 8 Replies View RelatedIdk what these types of books are called but we've all seen them. the types of books where you read a few pages and then you decide what the character(s) do(es) and you turn a certain page.
basically my question is are there any apps that are like those story books?
