I am looking for some sample code or tutorial that sets up the most basic opengl es application.
for example, just do glClear() in the renderloop.
i have already been searching the web but all i found was either out of date or too much and too complicated.

I am looking a way to use Emma on Android project. I have an application -project, and withing that, I have Junit test cases. Now How do I use Emma tool(command line) to get code coverage report on testcases?
I searched a lot but could not find a good/simple tutorial. I read somewhere that Android ant lib has a target "coverage" that does all thing, (running test cases, generating emma report). How do I use that?
I'm having great difficulty getting basic textures to work in an OpenGL ES app on my Droid (2.1-update1). I trying to render a simple textured quad - four vertices, two faces, with normals and texture coords. When rendered, the texture is garbled and full of static, similar to TV noise. The basic colors from the texture map are there, but obviously the texture isn't being read or applied correctly. My texture load sequence is simple : int[] textures = new int[1]; gl.glGenTextures(1, textures, 0); Bitmap bmp = BitmapFactory.decodeResource(cx.getResources(), R.drawable.img); gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[0]); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bmp, 0);...

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've been checking out the Canvas-based "CubeLiveWallpaper" which uses Paint to create a rotating 3D Cube and it works very well. I've been trying to get my head wrapped around how to move/port the GLSurfaceViewActivity/CubeRenderer/Cube from the API samples into a Wallpaper Service but I'm not having much luck.
Basically, I'd like to take the OpenGL cube from the API sample and turn it into a "Live Wallpaper." Does anyone have any ideas, samples, examples I could work off of or where to get started?

I downloaded the Android SDK and the Eclipse Plugin and installed them. When I however use the "Open Declaration" in Eclipse on basic Android functions and classes such as setOnClickListener or ListActivity it gives me an "Source not found"-Error.
The total Android source code seems to be 2.1 GB. Where do I get the source code of those functions that I call with the API to integrate it into Eclipse?
I would like to convert an image to text. ie take a picture of a receipt. Could someone point me in the direction of a tutorial or sample code.
View 2 Replies View RelatedI 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 need to be able to scroll through a list with (up to) 20K rows, backed by a cursor on a read-only db. Testing 20K rows on a G1, the query takes approx .02s regardless of table size, while binding the adapter to the list takes 4.5s. Note that this is before the view calls used in rendering. What makes the binding delay more troublesome is that it blocks the UI thread, and is incurred on every rotate. Combine these, and doing a rotate just after starting the bind results in a delay up to 9s.
I tried lazy loading with a base adapter, but that hits the same delay in the underlying cursor.getCount(), and the overall user experience isn't ideal. I also considered using an ArrayAdapter, adding synthesized objects from the cursor rows, but then I'd incur the overhead of creating up to 20K objects (not to mention the additional memory requirements).
I want to know all the names of character sets(as know as "character encoding") that are available on the android platform, I searched that how to enumerate it but didn't find.

All the other docks that I've found are window mounted suction cup deals. Does anyone know of a dock that plugs into the cigarette lighter, but doesn't have the FM transmitter?

I have the Android Facebook-Connect library running in my emulator and I'm able to set my status with the Facebook API I have setup. However, I don't know where to go from there? Am I supposed to use the session key that this library allows me to get and make some Facebook API calls? I haven't found any code examples to even see what the proper syntax is. Am I better off using another library? I tried fbrocket with limited luck(I get a "server error 104 - Incorrect signature").

For example, if there has any problem in Android API (e.g. Date and Time), it makes customer spend money and time more. But I can't find any report about verifying API test. If you have any information about it, please let me know :) Also if there has no information, how can I test some API to verify API.
View 4 Replies View RelatedI am a complete novice to the field of Android applications. I want to build a basic Android application of an "website alert and post service".
Eg: Lets take FACEBOOK or TWITTER as the website.The application which I design should intimate me about the new posts or tweets of my friends. At the same time I must be able to post or tweet just by opening a text box in the application and writing in it. As soon as I write, the message should get posted or tweeted on the website.
I am not sure about the complexity of the above application but I feel this would reduce the trouble of opening a browser, typing the website name and then logging in by putting the username and password.
