Android :: Good OpenGL ES Book?
Nov 2, 2010
I'm looking for a good book to buy to help me with OpenGL ES. This is obviously going to be for Android, but I suppose the benefits will spill over to iPhone development too. Although I'm not specifically opposed to a general OpenGL book, I'm not going to be using it on my desktop (at least not professionally). Wouldn't hurt to throw a few good online references too, although what I've found with online tutorials is that they teach a code snippet but not the whole picture. Or, they don't target ES (embedded systems, like Android).

Anyone know of a really good phone book type app for the Hero? I hate the organization of the Hero's contacts, etc. The moment for peats sake has at least the tabular tabs at the top for organization. I like that.. I saw Phonebook in the market, but the reviews dont speak volumes.

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?

The Gmail address book on the Web contains a field for birthdays, so why not the Android address book? While I'm sure the app could undergo a lot of changes (and everyone would have different ideas) something as basic as a birthday seems obvious.

Is there one? I have "Professional Android 2 Application Development" by Meier and "Teach Yourself Android Application Development in 24 Hours" by Darcy/Conder. Both are mediocre at best. Neither is a decent REFERENCE, but rather they are basically structured as tutorials, without nothing in the way of reasonably comprehensive API documentation (which also, BTW, is woefully inadequate on the android.com site). And no sort of in-depth discussion of the structure of the system, so one could perhaps understand it rather than simply using the (inadequate) cookbooks.

I've been looking at books scanning apps - you know, the ones that let you scan the barcodes on books you own and then identify the book and enter it into a database to help in keeping track and to avoid purchasing duplicates. Ideally, this information should be sortable using various keys. The bizarre thing is that after trying two or three, I haven't yet found one that will sort by author's last name! Honestly, who would want to sort by author's first name? (Is whatever is wrong with the People app catching or something? )

I am working on developing a 3d game. I have loaded ms3d model in my project and all texture and everything is working fine. I m not loading any joints.But I am facing two major problems which indeed are related to one thing. 1: I have got FPS problem in my game.Its too low even on G1. 2: When I have touch event to control the game it affects the FPSmore. So plz let me know how to optimize it more because the same game with same code of opengl es is wokring at 45 FPS on Iphone So why its running slow on G1.What is opengl es benchmark for G1 ? Wat can be comparison btwn Iphone and G1 related to hardware acceleration?

Been working with OpenGL a little more recently, and have been noticing pretty bad performance on my G1. Were there any major changes to OpenGL in 1.6 that would change the performance (or made my code incorrect?) on device? As a test, I grabbed the SpriteMethodTest out of Apps-For-Android, and gave it a spin. I had run it a few months ago and noticed pretty decent performance. With a low number of sprites (10-100), every method (Verts, Hardware VBO's, and DrawTex) had easily over 30fps, with drawTex beating out the others. I fired it up on my G1 (recently updated to 1.6), and all 3 methods are giving me performance of around 10-12fps with all methods of OpenGL at 10 sprites. Just for fun, installed the exact same APK on my girlfriends phone, which has yet to be updated to 1.6, and hers shows what I expected to start with, 30-60fps depending on method. So the question is, did anything change in terms of OpenGL, that would make the example code in SpriteMethodTest less than optimal?

Before I upgraded to 2.2 I had to find a lot of memory space on my phone. I deleted and number of applications including Aldiko. I had only two books on that; just started using it. One I was reading, a download from Project Gutenberg, and the other, an epub, book was next in line. However when I reinstalled Aldiko, after the upgrade, the book I was reading is there but the epub book is not. The epub book is on /sd card/Import but when I ask Aldiko to import it says nothing found. How can I get Aldiko to import my book?

Could someone please explain to me how to use the address book? I'm so irritated with how user unfriendly the address book... and every contact I've ever contacted is, that I'm nearly ready to jump ship. Usually I go to the dialer, and just type in a name. For instance, when people ask me my work cell number, I have to look it up. Normally, I'll go to the dialer, type in the first three letters of my name, then select the icon on the right to go to my entry. Easy. But when I'm on a call, and someone asks for my number, I go to "people" (or what seems to be the address book) and I type the first three letters of my name and every entry for James Kever shows up as James Kever. So my work number, my email address, my home number... every entry for me shows up... but ONLY shows up as James Kever. I have no idea which of the four entries is my work number. It's the same when I search for other people. I have 6 entries for my brother... all of them say Chris Kever.

Can 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.
