I have follow an example of an opengl application and I don't know why is this thing happening...I have a GLSurfaceView with it's corresponding renderer drawing a triangle. But, instead of getting the whole view on screen, I have just the upper half, and it's also duplicated as you can see on the picure. I'm using a Nexus One.

I'm trying to create a drawable in xml, a rectangle with one gradient on the top half, and another on the bottom half.
This is NOT the way to do it, apparently:
CODE:................
How can I do this, preferably in a way that makes it stretchable to any height?
I bought a new droid for $20 haha lucky i think until i notice that the touch screen only works for the middle of the screen to the left so if yu cut the screen into thirds only the middle and left work assuming that yu cut it from top to bottom with the lights at the bottom for the home button etc. I opened it up cleaned all the flex cable with alcohol and waited for it to dry and it still does the same thing so my question is = do i need a new digitizer or is it a software problem or something that i dont even know?

And after that, I have been mostly studying and not using my phone... but the second half of the batter drains, it seems like, FASTER than the first half did! No music playing, no wi-fi, no internet browsing? Is this normal? Is it just the nature of these batteries?

Think similar to the Facebook widget where I touch a small arrow and the next City comes up.
I've just come to notice a problem with my desire, which I believe to be fairly long standing.For quite a long time I've been thinking that scrolling down lists/webpages/in apps etc has been quite stuttery, the wierd thing being that if you flick the list/page/whatever and let go (ie let the momentum take it) it's a lot smoother. I noticed today that when I'm scrolling with my finger on the top half of the screen it's actually really smooth, but as soon as my finger reaches the halfway point on the screen it starts to stutter. The stuttering isn't random, it seems like there's a grid of sensitivity on the screen, so it only catches up every 5mm or so (it feels like there's about 15 points of sensitivity horizontally on the screen).To test it I first downloaded the multitouch test app (as it purely reads from the driver where the touches are being detected and displays it on the screen). It still happened. I then downloaded a free drawing app, which seems to accentuate the problem, as when my finger reaches the midpoint of the screen it stops drawing altogether!I imagine it's probably a hardware problem as it's been happening for ages (only just recognised though) and during that time I've installed a debranded rom and then updated to froyo.Has anyone else noticed anything similar? I'll try and get a video on youtube to show the problem at some point. Any advice of things to try or should i just call T-Mobile support?

I am going back to screen protectors but I would say for a first scratch not a bad run. I have kept it naked since I bought it and have had kept in my keys with pockets. Honestly I wouldn't doubt thats how it happened !

View 3 Replies View RelatedI've just dusted off an application I did for Android half a year ago. I upgraded to the latest SDK and Eclipse ADT. After some struggeling I get the application to run again. When I debug it I can see that all the right code are executed the right way. The application shows a OpenGL surface and animates stuff on it. It used to work perfectly (I even have it running on my HTC Magic device), but in the new emulator the screen is just white?

I am very new to OpenGL ES. I am implementing some demo app to load multiple textures on the screen. For demo purpose I have loaded 2 textures in 2 different locations on the screen using glTranslatef() and glBindTextures() twice. Now I am able to see 2 different images on the screen. Now I want to move one particular texture across the screen using mouse.

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!

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?
Can somebody take me step-by-step how to draw 2D stuff over a 3D scene (such as controls, etc.). What I've been doing so far has not been working (it only draws the 3D scene), which is (in every frame): draw the 3D scene as normal, projection matrix mode, load identity, call GLU.gluOrtho2D(gl, 0, myScreenWidthInPixels, 0, myScreenHeightInPixels), switch the array pointers (vertices and texture coords) to the ones for my 2D stuff, then drawElements with an appropriate index list. (then switch the array pointers back so the 3D stuff works again).I get nothing added to the screen (just the 3D stuff).Do I need to be doing something else for it to draw? Can somebody take me step-by-step?

View 3 Replies View RelatedI'm developing an Android application. I'm very new on it. I have the following classes:
class CustomGLSurfaceView extends GLSurfaceView
class CustomRenderer implements GLSurfaceView.Renderer
CustomGLSurfaceView uses CustomRenderer to render a cube on onDrawFrame method.
I've added an onTouchEvent(MotionEvent event) on CustomGLSurfaceView to manage touch events:
class CustomGLSurfaceView extends GLSurfaceView {
// For touch inputs - previous touch (x, y)
private float previousX; private float previousY;
private CustomRenderer myRenderer; public CustomGLSurfaceView(Context context) {
super(context); myRenderer = new CustomRenderer(); setRenderer(myRenderer);
} @Override public boolean onTouchEvent(MotionEvent event) {
float currentX = event.getX(); float currentY = event.getY();
switch (event.getAction()) { case MotionEvent.ACTION_MOVE:
myRenderer.handleMovement(currentY, currentY, previousX, previousY);
} // Save current x, y
previousX = currentX; previousY = currentY;
return true; // Event handled } }
May I have to modify onDrawFrame to draw something new or to rotate the cube? I thing I must do it on handleMovement.
How do I use gl.gluUnproject in my OpenGL ES 1.1 android app to determine what is selected when the user touches the screen?
My understanding is that the touch event results in a line and I have to find the first "thing" it intersects with.
Are there any tutorials on how to do this?
I've been working on a game framework for a little while, and while its far from perfect, I've put the current version online. To be honest, I haven't used much OpenGL in the past. Before last week I had never tried using it. If anyone would like to take a look, please do, I'd appreciate all the help possible on speeding it up. There are many features I have in mind and am planning at the minute, but so far it supports:
# Texture and Sprite management # Text, using TTF fonts # Organised layers # Two audio management classes, one optimized for music, the other for sound effects # Sprite dynamics (acceleration, terminal velocity, collisions) # Animation # Handlers to manage events fired through movement, animation, screen touches, accelerometer input, device shaking and collisions # Several minor features aimed at speeding development, such as screen settings and vibration.

View 2 Replies View RelatedI have written a object selection algorithm which picks the objects by their color. i give every object an unique color and then i just have to use the glReadPixels method to check which object was selected
this works fine and is really fast but the problem is that the frame is displayed on the screen with all the picking-colors so the screen flashes every time you select something.
so my question is: how do i write everything in the correct display buffer but dont display it on the screen to avoid these flashes?
So a few days ago I went to download a few apps. None of them seemed to want to download and I was pretty annoyed about this for about 2 days. Suddenly the Market seemed to work again, and I got 5 or 6 notifications of successfully installed apps. Winner
Unfortunately, there's one that seems not to have downloaded: "Street View On Google Maps". It thinks it's downloaded, but it's not there. If I go to delete apps on my phone, I can't see it. If I go to place an app or a widget on my home page, I can't see it. However, if I find it in the market, it says it's installed. And if I tap it in the market, both the "Open" and "Uninstall" buttons are greyed out. Does anyone have any idea what's going on here and how I can fix it? If it makes any difference, I'm on a HTC Desire HD.
I have seekbar wich is for example 100dp height. How can i make only the top 50dp to be clickable and the down 50dp just to be covered with the progress.
View 2 Replies View RelatedBasically I have a fully functional ogl program (2D game) in opengl es 1.1, everything works fine except for one problem: glcolor
I'm trying to set some of my texture to half transparent and I would like to do it as follows;
gl.glColor4f(1f, 1f, 1f, .5f);
obj.draw(gl);
...
gl.glColor4f(1f, 1f, 1f, 1f);
I'm using VBO for my vertice, my textures and indices. (if that is relevant)
the problem is that nothing gets set to 50% transparency...
I'm don't think relevant to post all my code (mainly because it is spread out several classes with several GL options changing (blends, scissors etc etc).
What I would like is for people to tell me what state of OGL could prevent glcolor form working like I want, what functions should I check, what state should I call.
My app suddenly lost half its installs. Both on the Market website and on the device Market app.
