I plugged in my phone at roughly midnight last nite.. when i woke up i checked my BatteryIndicator app and it said it had been fully charged since 12:52 am... somehow i think that that cannot be right... full charge in a single hour?
I just looked at my SystemPanel app to check the usage history and it showed this...
At 10:52 i took a screenshot that shows that my battery had gone down from 100% at 7:28 when i unplugged it, to 59% (see picture below).. I had light-moderate usage during this time as the following picture from SystemPanel will show.. the phone was inactive for a while (blue) and the CPU was only a little active, about 10%(bottom Green) yet the battery still was draining pretty rapidly...
This picture shows that the first 30 mins ate 5%-10% of my battery..
- I have animations off
- No live backgroung
- I have changed my radio from GSM auto (prl) to CDMA auto (prl) <- that eliminates the cell standby battery usage by elimitating the time without a signal (used to be 20%, now its 1%)
- I have only the mobile setting on (GPS, 4G, Bluetooth, Hotspot are all off)
Basically i have turned off all the settings that make this phone better then my Treo 700WX
I have serious issues using the eglMakeCurrent() method of the EGL10 class.
1) After a successful call ot the eglMakeCurrent method with an eglSurface & an eglContext, if i request the current context and the current surface (eglGetCurrentContext() & eglGetCurrentSurface (EGL10.EGL_DRAW)) i get different instances compared with the one that i've passed. Even the equals method fails.
2) After initializing the eglDisplay and before any call to eglMakeCurrent(), if i request the current context and the current surface i recive instances that are not the EGL10.EGL_NO_CONTEXT and EGL10.EGL_NO_SURFACE.
I'm developping a native application for android and I face to artefacts when rendering the scene. I can reproduce the issue with Java code.
While the following code running, I got a green screen. But If I move the status bar up and down over the screen, I see some red artefacts.

How to play video using opengl es in android?
View 3 Replies View RelatedI'm writing a little 3D engine for android to better learn the platform and opengl. I hope to eventually use it as a base for little 3D games.
I'm trying to implement lighting right now, and generally following the NeHe opengl android port tutorials. I have a simple spinning cube and 1 light that should not change position. Upon rendering my scene on a device the light appears to "dim" and re-lighten as cube rotates.
This is a swf video of the behavior:
http://drop.io/obzfq4g
The code for my "engine" is located here: [url]
The relevant bits are:
[url]
This is where I'm initializing opengl and setting up my scene. and [url]this is the code for actually rotating / drawing the cube mesh.
I wish I could formulate a better question; but I'm very stuck/confused and can't even think of an intelligent question to ask besides "does anyone know what might cause the kind of behavior I'm seeing?"
Also the slowness / choppyness of the animation in the video is a result of the screencap software. It's smooth throughout the whole rotation on the emu.
From the posting so far I have seen, the current emulator as of API level 8 and Platform 2.2 does not support OpenGL ES 2.0. (Only in the emulator that the support is not there)
(The support is there at API level 8 for the ES 2.0)
wondering if any jone has figured out the following
1. Will the emulator support ES 2.0 in the future (considering there is compilers, shaders etc needed to support es 2.0) 2. What is a likely timeframe this may be available? (months or sometime future?)
I suppose considering that iPhone SDK has the emulator suppor for es 2.0, it can be anticipated on the Android emulator as well.
In my application I'm trying to create a mesh that is shaded by a single directional light. The problem I'm facing is that I can't seem to get the light to take my normals into account at all.
It works fine if I set the normals on a per-triangle-strip basis, but if I try to render a series of triangles with normals set using the glNormalPointer method the entire mesh is rendered using the same color (which is identical to the result I'm getting if I skip calling glNormalPointer all together).
My mesh render method looks like this:

I am drawing some textures with alpha channel, but when they are displayed it looks like the alpha channel is only binary. So a pixel is either transparent or opaque, although in the texture file itself the pixel is half-transparent.
The blending is set up like this:
code:............
The above shows how it should be like, and the below shows how it is:
I'm having a hard time deciding whether to go with Quartz2D or OpenGL for an iPad game. It will be 2D mostly, but effect-intense (simultaneous lighting effects for 10-30 objects, 10-20 simultaneous animations on the screen). So far, assuming i'm equally dumb in both technologies and have to learn them from the ground, i came to this list. (I've read several topics here, on SO, with names like "Quartz or OpenGL", but i'm still left with some questions)
View 1 Replies View RelatedJust couldn't find anything regarding the purpose of android.opengl classes anywhere on the web: they seem to be copies of javax.microedition.khronos.opengles - just with static vs member methods.
So is there any special meaning in using them instead of j2me classes: are they supposed to be faster, have additional functionality, simpler to work with? I think of using them instead of passing that gl reference all the time.
I want to learn Android development so I downlosded the Eclipse and configure it with ADT plugin with lots of hassle. When I open SDK manager it open the repository list that are needed to download lije Android4.O files, Google APIs ,System image etc. Though I was on slow internet connection. I read a tutorial to download google api and sysimg separately by copying the link from xml file. but now I dont know where I have to put these files in the main folders.
I have
1) Googleapi16_r03
2) sysimg_armv7a-16_r03

View 6 Replies View RelatedThis seems like an obvious thing, but I can't find any way to do it.When I put my phone in the car dock, instead of auto-launching the official "car dock" application, I want to launch an app of my own choosing. (in this case vlingo)I can find various apps that specifically replace the car dock app, but that's not what I want, I want to use vlingo (which doesn't seem to have that option by default)Just to be clear, I don't want an app that gives me an icon I can click to launch vlingo, that would defeat the purpose as I can already click the icon on my home screen to launch it if I want.So how can I set what program launches when I drop it in the car dock?
