Nov 2, 2009

Dear all, I want to implement the transition effect ( transparent with Z axis ) when user slip the android home to change home page. therefore, I plan to launch the new activity that is implemented by OpenGL ES to perform this effect. However, i encounter a problem that the screen/display is dark momentarily when launching the OpenGL ES activity.

Android :: How To Get Screen All Dark But Still Touch Sensitive

Aug 23, 2010

I want to get the display as dark as possible but I also want the display to remain touch sensitive.So I can't turn the display off, otherwise it wouldn't react to touch anymore. And I use WindowManager. LayoutParams. screenBrightness to get the screen as dark as possible. And I put a layer colored black over the entire display.That works, but at night one sees that the screen is still quite strongly illuminated.Does anybody have an idea of how to get the screen even darker?

Android :: How To Find Out Screen Status Active / Dark?

May 28, 2009

I've dug through the documentation but couldn't find a call that would fit: Is there a way to find out the screen status (Active/dark)?I've got an app that implements the relevant data processing and backend server connectivity through a Service that I keep running on a reduced activity level when the user puts the device to sleep (using end button), or when the screen timeout hits. In the app code, I can follow this status change, because it triggers calls to overloaded onStop() and onPause() methods of the app's subclassed Activity. This way, I control active/reduced ("sleep") activity levels of that Service. Everything's cool and dandy in this scenario.Enter an AppWidget that's using this Service in a similar fashion, with functionality implemented in a subclass of AppWidgetProvider. This changes the game - I have found no way to determine when to set the Service to the reduced ("sleep") activity level from that point. The app's Activity has long paused, and I keep the Service at active level, as the widget needs updates from the Service similar to what the Activity needs when in front. With the AppWidget on the home screen, I want, and should (re: battery life), drop the Service's activity level when the device enters sleep mode. The most elegant way to handle this would be to detect whether the screen is dark, right inside the Service.

Motorola Droid X :: Way To Fix Dark Screen?

Nov 26, 2010

A girl at work spilled her drink of water by my phone and of course it got wet. I did the whole sit in rice for 3 days and hit it with a lite blow drying. After I turned it back on everything works perfect (can text and receive calls, ect) except the screen is so dark I can only see it (hologram type effect) in super bright light and tilted at an angel. And even then its barley visible. To my surprise yesterday the screen lit right up back to normal and I almost died, but by that night its back to dark. I have no insurance and have about 8 months left on my contract. I talked to some verizon people and the best scenarios for me would to be A) Buy another Droid X from like craigslist and switch everything over. Cheapest I seen in my area is $375 or B) Ad a line and get a new Droid X w/2 year contract for $200 and switch the info over and pay the data fee on the old one I cant use I'm not asking so much for help on those options, but more if anyone knows any tips to maybe fix the screen (if it is a screen problem and not hardware). It just sucks because it works perfect and it did come back on so I know (kinda) that it must be capable of doing it again.

Android :: Render OpenGL To Regular View - Not GLSurfaceView

Aug 19, 2009

I've noticed that OpenGLContext is removed from 1.5. Everybody says that GLSurfaceView should be used instead. Does this mean that there is no way to render OpenGL graphics into a regular View?

Android :: Setup OpenGL View Inside A Layout?

Nov 8, 2010

How do I set up an xml layout where an OpenGL view is part of it? As I do now is set the OpenGL view as the only view with setContentView(). But I would like to create an xml layout that includes the OpenGL view. Lets say I want to have the OpenGL view mainly and a small TextView at the bottom.

Is this even possible? Or can an OpenGL view only be the one and only view?

HTC Droid Eris :: Getting Screen To Come Back On In Dark

Jan 4, 2010

Forgive me if someone else has asked this, but I searched the forum and couldn't find an answer.I understand that the proximity/light sensor turns off the screen when the Eris is next to your ear to prevent "face dailing", etc. And, I understand the screen comes back on when the sensor senses light. Ok, that works fine.BUT, what do you do if you are using the phone in the dark? When I pull the phone away, the screen will not come back on because it does not sense light. For example, trying to delete a voicemail if you're using the phone in the dark. I've tried every button to re-activate the screen, and the only one that will work is the "End" key. And that obviously ends the call.

Motorola Droid :: Screen Goes Dark When Dialing

Apr 1, 2010

This may be just me or my combo of applications but, When I enter a number on the touchpad and press dial the screen goes dark and will not come back or accept input unless I put the phone to my face or otherwise cover the the light sensor. Even pressing the power button does not bring the screen back . I have forced the 2.1 update and have not noticed this behavior before. Not a big deal but is annoying if you dial a wrong number.

Android :: White Screen In OpenGL Application

Oct 23, 2009

I'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.

Android :: OpenGL Speed Issue - Code Contribution To Other OpenGL

Feb 25, 2009

Single 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, 2010

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?

Android :: Drawing 2D Stuff On Screen In OpenGL Over 3D Scene

Jun 27, 2010

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?

Android :: Changing Drawing With OpenGl When User Touches Screen

Nov 10, 2010

I'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.

Android :: Use Gl.gluUnproject In OpenGL ES 1.1 Phone App To Know What Is Touched In 3D Space From Screen

Mar 21, 2010

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?

Android :: OpenGL 2D Game Framework - Speeding / Screen Settings / Vibration

Sep 18, 2009

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.

Android :: Opengl Es Color Picking On Android Without Screen Flashing

May 3, 2010

I 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?
