In Linux, we can get the framebuffer directly by "open("/dev/fb0", O_RDWR);"
Is there any way I can call the similar function via JNI in Android or how can I access the frame buffer directly in Android?

Is there a method to read the frame buffer of the current screen? I searched some data about the frame buffer. Some one used the glReadPixels method, but the information was not enough. Does anyone know how to read the current frame buffer in detail?

View 1 Replies View RelatedMy application cannot handle the JNIE overhead, as I need to make 2 JNIE calls to the native C/C++ code for every 20msec. So I am trying to use the native media libraries and the realted C/C++ files provided by Android in the folder "//external/srec/audio/test" of the donut build. Ex. AudioHardwareRecord, AudioInRecord etc.. I am implementing all the calls in the native layer.
I am using the sampling rate as 8000 and want to read 160 samples (320 bytes) at a time.
I used the following values to create the AudioRecord..
CODE:..........
It says "success" after creating this interface but I am getting the error "Bad Value" if I am doing the InitCheck.
And it is crashing once I start reading the samples or if I try to retrieve the configured sampling rate.
Has anybody tried to access this native code?
Had my phone two days and I've already managed to screw it up. Gmail through the browser works fine. Notifications of new mail work fine; I can pull down the notifications bar up top, click on the mail note, and read/mark everything fine from there. But I'm screwed once I exit that. See, I can't just access gmail directly through the app. If I click on it, I get a black screen saying "your mail will appear shortly" and a note in the bar up top saying "waiting for sync". Just cleared Gmail data.
View 4 Replies View RelatedIs it possible, from within my android java app, to capture an image of what is on the screen, even if it was written using native (ndk)? I do not wish to take screen shots of other apps, just my own. I can already capture and image of a canvas that I am aware of, but is there a view or canvas or something like it that always represents what is on the screen, so that a) I don't have to capture the separate views images and recompile them, and b) I can see what my native (jni) code is doing with the graphics too?

View 3 Replies View RelatedI've created an application that show around 250 images in ImageView. Images are loaded one after another, 15-30 images per second. Basically the whole thing gives an illusion of a rotating 3D object, at least it should.
The problem is next, app hangs when loading certain images(i.e. I see a few seconds of fluid animation and then animation hangs, jump 10-15 frames(images) ahead and continues. It always happens at the same places in animation cycle.
I though that Android might not have enough resources to handle something like this, so I've resized images to half their size, but it did't help. I've tried buffering images but that did't help either(actually, maybe a little, I think that animation looks a little bit smoother).
And now the weirdest thing. I use the touch screen to allow users to "rotate" the 3D object on those images, and while rotating I again experience those hangs at exactly the same places as with the animation.
All images are in .png format and their size vary from 15kB to 40kB.
I use the following code for the animation:

View 1 Replies View RelatedI'm still pretty new to using Android, but I decided that my first application would be a simple flashlight app for my new Incredible. Unfortunately, it seems to be more difficult than I had originally thought.
It seems that there's no way to access the LEDs through the SDK, at least not without a bunch of weird hacks to make the phone pretend that it's taking a picture. Even then, I can only get the LEDs to turn on. They only turn off if the phone is put on hold, and doing so breaks all camera-related apps until the phone is rebooted.
So, I was wondering if accessing the LEDs through the NDK was possible, or if there was any other camera-related APIs that would seem to do what I want.
I've looked at other code for other flashlights, so it looks like it's a hardware-based problem. I figured I'd give up because it doesn't appear to be possible, but I thought I should ask here first on the off-chance somebody knows something that I don't.
I am looking for a way to get sensors' data ( especially Accelerometer) directly without using Listener approach. Actually I need to have the data really fast! I can not find any way to read sensor data by myself. Anybody knows anything about it? Is it possible to read data with more than 50Hz?

It does install to the emulator. It all seems to work. I go in to the live wallpaper menu, find my live wallpaper in there open it, it loads. but its not moving through the frames.

I want to add frame to image with title and subtitle. The thing that I want to do is as follows : There are number of styled frames available and user selects any picture from the phone memory or takes a picture from camera, now on selecting any frame that picture should be in that frame. Also below that frame there should be title and subtitle of the image.
I hope I have made it clear of what I want to know.

View 6 Replies View RelatedIs it possible to generate an EGL Config with an alpha buffer on the G1? When I request a non-zero number of bits for the alpha buffer I can get a R5G5B5A1 or R8G8B8A8 visual, but neither of them renders correctly to the screen. I assume that's because the G1 only supports R5G6B5 visuals. It does surprise me that I can even get those visuals though. It's fairly obvious looking at the 32bpp visual artifacts that the frame buffer is indeed laid out with 32bpp, but display hardware is treating it as 16bpp, resulting in the left and right halves of my scene rendering in alternate scan lines, with distorted colors. So does anyone know if there is any way to get an alpha buffer on the G1? I've tried using FBO's but they don't seem to be implemented either. Or I'm using them incorrectly. If I call glGenFrameBuffersOES on a GL11ExtensionPack reference I get an UnsupportedOperationException. I am getting my GL11ExtensionPack reference by casting the return value from my EGLContext.getGL() call.

I was having trouble getting my G1 to render an RGBA_8888 OpenGL context to the screen. Everything was twice the size it should be because the 8888 pixels were being interpreted as two 565 pixels. The colors were obviously wrong as well. I had missed a critical function call. You must configure the Surface that is being used by EGL using the SurfaceHolder method setFormat. The pixel format needs to be TRANSLUCENT, or more specifically you can use RGBA_8888.
View 2 Replies View RelatedHow can I empty the logcat buffer in Android? I use adb logcat from command line and pipe the output to a file, since the DDMS has a very limited buffer. At the moment, when I restart my app (after fixing bugs etc) the logcat buffer has data from the previous launch as well. Even uninstalling the app does not clear the buffer. The only way I've found so far to clear the buffer, is reboot. This is effective, but would like to know if there's an easier way.
