Can I assume that, if a phone runs Android 2.0, it also supports OpenGL ES 2.0 and thus the graphic hardware has full support for programmable shaders?
IOW, does Android 2.0 as a platform mandate OpenGL ES 2.0 support? Or is it optional?

Does anyone know whether the G1 device is capable of supporting OpenGL ES 1.1? Is this something that depends on both the graphics chip and the OS, or is it purely software? If Android/the G1 only supports OpenGL ES 1.0, are there any pieces of the 1.1 spec that are supported?

The added TableLayout count is dynamic. It would be between 1 - 10.
I think it is better way to make it from resource xml. Because design doesn't break.
How to make it ? Actually I don't know how to create a new instance from the XML.
Does anyone know of a cheap Android or programmable device that has wifi? I need it for a project for a company that needs a wifi handheld device for the shop floor. Im not too fussed about the language the device uses though Im not really interested in the iTouch as theres no intention to release the app in the app store and I don`t really want to jail break everybodys iTouch. Ideally it would be small , iTouch size for example and relatively cheap $100 or less. Nothing fancy just ability to write a simple UI and have wifi. Voice is not needed.

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 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?
In android 2D UI, what's the function of opengl?

We are getting a SIGSEGV 11 when launching our OpenGL activity. Here is the logcat. It appears to happen on Droid Hardware, but not the 2.0 Emulator. We are trying to do some testing to see if we can slowly build up some code to cause a crash.
CODE:....................
I ran into a rather strange problem with my OpenGL game. While most textures look good, five or six are not drawn on Droid, and I don't see anything special about these images/models. For example, my HUD is made of 4 elements. The upper part is drawn correctly, while the lower part appears as white rectangles. The code used for loading and drawing these models and textures is exactly the same. Textures are 32-bit TGAs in both cases, POT dimensions, in - nodpi, inScaled==false, using GLSurfaceView to rule out configuration issues. No problems on G1 and Hero (and of course on emulator). And I don't have the Droid, so I can't just try whatever comes to my mind. Asked users to send me logs - no errors, all models and images appear to load normally.

If I understand correctly though the GPU in the Droid 1 is ES2.0 Compliant, so it should have at least 2 texture units, any idea why I'm getting this weird look in my app on the Droid 1?
I am working on a app which render geometrics with VBO in NDK opengl, it works in other phone, but in Motola Droid, it will cause the devices reboot.
The logs like next.

I just got my hands on this phone.
Here's my summary:
1) It's really fast. Runs all my games at max framerates.
2) The screen is 16:9 and will probably mess with your layouts and games and stuff.
3) It has a PowerVR SGX530. That's right around iPhone 3GS's GPU speed.
I believe the hardware supports OpenGL ES 2.0 but since Android doesn't, there's no way to use it right now. I did, however, dump all of the GL extensions and put them alongside the G1 and Emulator extension lists into this handy-dandy article - http://www.rbgrn.net/content/345-hands-on-motorola-droid-opengl-es-specs

If i wanna use the opengl interface in android ndk， then will it be possible to show

i just wanna know how to operate in android ndk first.
I'm writing a game engine.
I have a little example (see http://qrcode.kaywa.com/img.php?s=8&d=http://rokonandroid.com/rd.apk), that seems to work fine on every device except Droid / Milestone.
It displays a blue screen (due to glClearColor being set to blue), and nothing more.
I have tried with/without textures, and with/without VBOs. Yet still all blue screens on Droid.
What is unique about Droid and how it handles OpenGL, and why is it doing this?
Has anyone found a way to enable antialiasing in OpenGL on any of the Android devices?

View 1 Replies View RelatedOnce again I'm trying to get into openGL, but as usual I choke when passing around vertices/vertixes/whatever and every little detail can lead to disaster (wrong format, initialization not properly set up, where memory are saved, etc.).
My main goal is to use openGL for 2D graphics to speed up performance compared to regular cpu drawing.
Anyways, my openGL Renderer looks like this code...
With an IndexOutOfBoundsException, but I'm sure there are more problems with the code.
Since both iPhone and Android support OpenGL ES, is there any open source or commercial GUI library we can use for these two platforms? Or is it doable (or how difficult) to port an application from one to another platform?
As I know, for iPhone only, libNUI (http://www.libnui.net) is a good choice (dynamic layout & mature), but it only provides GPL & commercial license. Any other open source tool similar with libNUI?
I'm am working on a basic augmented reality application on Android. What I did so far is detect a square with opencv and then using cvFindExtrinsicCameraParams2() I calculated a rotation and translation vector. For this I used 4 object points, which are just the corners of a square around (0,0,0) and the 4 corners of the square in the image.
This yields me a pretty good rotation and translation matrix. I also calculated the rotation matrix with cvRodrigues2() since using this is easier than the rotation vector. As long as I use these to draw some points in the image everything works fine. My next step is however to pass these vectors and the matrix back to java and then use them with OpenGL to draw a square in an OpenGLView. The square should be exactly around the square in the image which is displayed behind the OpenGLView.
My problem is that I cannot find the correct way of using the rotation matrix and translation vector in OpenGL. I started of with exactly the same object points as used for the openCV functions. Then I applied the rotation matrix and translation vector in pretty much any possible way I could think of. Sadly none of these approaches produce a result which is anyway near what I hoped for. So my question is can anyone tell me how to use them correctly?
So far the "closest" results I have gotten, was when randomly multiplying the whole matrix with -1. But most of the time the squares still look mirror inverted or rotated for 180 degrees. So I guess it was just a lucky hit, but not the right approach.
I currently have a game written using the Android canvas. It is completely 2D, and I draw bitmaps as sprites on the canvas, and it technically works, but I have a few features that I need to add that will require drawing many more bitmaps on the screen, and there will be a lot more movement.
The app needs more power.
What is the best way to go from this method of drawing Bitmaps on a canvas to using OpenGL so I can draw them faster?
As with a lot of folks doing OpenGL ES dev it's really a test on device situation. I'm really trying to get out the Typhon API (http:// typhon.egrsoftware.com/) which is an open source platform for real time / game development working on the Droid. It also provides the basis for a series of OpenGL ES tutorials for Android available that will be incrementally released starting this week with or without support for the Droid: [url]
Of course I'd like to support Android 2.0 / Motorola Droid, but alas a problem without a clear answer is occurring when I use EGL/GL directly not using Google/Android provided GLSurfaceView. The following is the basic setup code and works just fine on all previous Android versions including 1.6 on the G1 and Ion, but it fails on the Droid. Note "context.getConfigSpec()" returns a standard configuration:
new int[] { EGL10.EGL_RED_SIZE, 5, EGL10.EGL_GREEN_SIZE, 6, EGL10.EGL_BLUE_SIZE, 5, EGL10.EGL_NONE }
Will android OS support unicode ?

View 2 Replies View RelatedI had assumed that the Motorola Droid supports the new multitouch APIs in Android 2.0, but the reviews of the device I've seen so far say that it isn't used, at least in the built-in apps like the browser (e.g: http://www.engadget.com/2009/10/30/motorola-droid-review/ ). Apparently though, it is supported on the upcoming GSM version of the same handset [url], so perhaps it is just an issue of whether the driver is included on the Droid version of the software. Can anyone with access to a Droid confirm whether the multitouch API works on it?
