General :: Enable Correct Indic Language Rendering (Bengali) In CM 9 Devices?
Sep 2, 2012I am a Linux enthusiastic and now using the most awesome mobile operating system Android ICS.
My mobile phone is Sony Ericsson Live with Walkman wt19i. Recently I installed CYANOGEN MOD 9 which I think the best available rom from the performance perspectives.
But one problem popped out.
The problem is this Rom can't render Indic languages well.
The fonts are not perfect.
The encoding is set to UTF 8, but still it can't render the BENGALI LANGUAGE LIKE THAT OF SONY ERICSSON STOCK ROMS.
Android :: OpenGL Speed Issue - Code Contribution To Other OpenGL
Feb 25, 2009Single 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 ?
Android :: NDK OpenGL - Mixing Java And Native - C - Calls To OpenGL API
Jul 24, 2010I 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?

Android :: SIGSEGV 11 OpenGL - Only On Droid - Not 2.0 Emulator
Nov 10, 2009We 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.

Android :: Blank Textures On Droid (OpenGL)
Dec 28, 2009I 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?

Android :: Motorola Droid OpenGL ES Specs?
Oct 28, 2009I 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

Android :: OpenGL Doesn't Render On Droid - Milestone
Jun 29, 2010I'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?
Android :: Droid 2.0 And OpenGL ES 2.0 Support For Programmable Shaders?
Jul 9, 2010Can 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?

View 1 Replies View RelatedAndroid :: Droid OpenGL ES Test Renderer Crash / Why Is So?
Oct 8, 2010Once 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.
Android :: GUI Libaray For IPhone / Droid Based On OpenGL ES?
Mar 18, 2010Since 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?
Android :: Use An OpenCV Rotation And Translation Vector With OpenGL ES In Droid?
Sep 14, 2010I'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.
Android :: Method To Draw Bitmaps Faster On Droid Canvas / OpenGL?
Jun 15, 2010I 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?

View 3 Replies View RelatedAndroid :: Communication Between Droid Devices Over 3G?
Aug 25, 2009I'm not *entirely* sure this one is supposed to go here, but anyway :)
Assuming I have two Android-powered devices, connected both to the same 3G network; does the current API of Android allow to have a Service running on one of them being contacted by an Application running on the other one over this 3G network or do I have to go for a more traditional network (e.g. WiFi AP, Bluetooth) ? If so, how do I do it ?
I saw the usual Socket part in the API but it is not clear to me whether this is the way to use the 3G. I also found another discussion related to communication between a laptop and a dev phone ("Sending data to android dev phone using 3G connection") so it seems to be possible.
Does anyone have some details about how to do this?

Android : How To Connect Two Droid Devices?
Aug 2, 2010What are the options to connect (create stream? or send datagrams?) between two android devices? (I know I can use Internet, but i think that lag will be big and it's overuse to just exchange data between to phones that are nearby). Is it possible to use bluetooth or wifi ? so two applications on two devices can connect each other (create bi- directional stream) and send some data.
