Android :: Missing OpenGL Drivers On Emulator
Jul 11, 2009
I am trying to set up an Android emulator to do some playing around with OpenGL ES on it, but I am stymied by the fact that, every time I run my program on it, it unceremoniously grenades itself. The problem (at least the first nasty red error line in the log) is a missing package called libhgl.so. This is the OpenGL driver file required for running OpenGL ES on Android devices, but for some reason, my emulator doesn't have it. Does anyone know where I can get drivers for the emulator, or how to get an emulator that already has them?

I'm trying to run the "HelloTriangle" example, from The OpenGL ES 2.0 Programming Guide, in the Android emulator.I import egl.EGLConfig and opengles.GL10 from javax.microedition.khronos, but the ESContext type and definitions such as GL_COMPILE_STATUS and GL_FRAGMENT_SHADER can't be resolved.I reworked the triangle example somewhat for Android in that I'm using GLSurfaceView. I undertand that it is supposed to be used instead of OpenGLContext in the newer versions of the SDK.Am I using a "non-Android" approach to OpenGL ES? If so, what's the right one?

We are getting a SIGSEGV 11 when launching our OpenGL activity. Here is the logcat. It appears to happen on Droid Hardware, but not the 2.0 Emulator. We are trying to do some testing to see if we can slowly build up some code to cause a crash.

In my application, I have a NDK native code that uses OpenGL 1.0 to apply a texture to a rectangle in order to draw an image on the screen. It is working fine on the emulator, but when I test it on the HTC HERO android device, it only draws a white rectangle without texture. Anybody else had the same problem? Did anybody find a solution?
Here is how I initialize openGL in native code:

And here is how I draw the frame in native code:

After spending the better half of this day getting my HTC Magic to work in developer mode, I've now found that some of my frist openGL coding attempts that appeared to work fine in the emulator doesn't work as expected on the device. I've narrowed this down to glColorf(r, g, b, a) not working as expected on the device itself. The provided OpenGL samples do work though. So for example, after modifying Cube.java from the samples to the below code I find that I get the expected grey square on the emulator but a blank white screen (background fill colour) on the device.
class Cube { public Cube() { int one = 0x10000; int vertices[] = { -one, -one, -one, one, one, -one, one, one, };
// Buffers to be passed to gl*Pointer() functions // must be direct, i.e., they must be placed on the // native heap where the garbage collector cannot // move them. // // Buffers with multi-byte datatypes (e.g., short, int, float) // must have their byte order set to native order
ByteBuffer vbb = ByteBuffer.allocateDirect(vertices.length*4); vbb.order(ByteOrder.nativeOrder()); mVertexBuffer = vbb.asIntBuffer(); mVertexBuffer.put(vertices); mVertexBuffer.position(0); }
public void draw(GL10 gl) { gl.glFrontFace(GL10.GL_CW); gl.glVertexPointer(2, gl.GL_FIXED, 0, mVertexBuffer); gl.glColor4f(0.5f, 0.5f, 0.5f, 0.5f); gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, 4); }
private IntBuffer mVertexBuffer;

Running into REALLY interesting problems with OpenGL ES. Basically when I start my program in 1.5 or 1.6 emulator, it works just fine but on HTC Hero 1.5 it does not. The problem is that the vertices are not being rendered but the gl.glClear() command is working just fine. I followed in with the debugger and it does go into the rendering function and such but still not rendering the vertices...
Here is the code in PasteBin (easier to read: http://pastebin.com/m706686e6 )
And here is the same thing pasted here:
CODE:............
Also I got my projection set in 2D ortho projection to match screen coordinates so that's why scale to 50,50 to actually make a bit bigger. I've tried using glDrawElements and glDrawArrays and nothing on the actual phone but works perfectly fine on the actual emulator. Any ideas where I might be going wrong? Why is the actual phone not rendering the vertices like the emulator is?

I've an app that uses Android accounts - GoogleLoginService on (< 2.1) and AccountManager on 2.1 or greater. the app works fine on phones, but doesn't work on any of the emulators.
When I try adding accounts in emulator, it fails. In 1.6, option doesn't even exist.
Is there a workaround? I heard that there is a custom system.img that has Accounts inbuilt, but cant find one. I need it for 1.6, 2.1, 2.2

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 ?

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?

I created a sqlite database to store playlists for a media player I am developing because of extended feature (rather than using the Content Provider). It works perfectly on the 1.6 emulator but FCs on anything higher than 2.0... what has changed that I need to know about as far as opening databases in SDK 2.0+? Here is the logcat.

Finally strace gave me this:
CODE:................
And several other attempts to call "link" that also fail (sshfs does not support hard links).
Is it possible to change the emulator's behavior to create lock files somewhere in /tmp (using some hash of image path as lock file name)? I am OK to try this myself: which repositories from https://android.git.kernel.org/ are necessary to rebuild the emulator alone, and where in the sources is the code responsible for image locks?

I need to run several emulator instances to test my application. When i try to run instances using emulator -data <path> option, the emulator crashes.
I got a MS Visual Studio window informing that emulator throws a "unhandled win32 exception".
The exception message in the debugger (MS Visual Studio 2008) is: "Unhandled exception at 0x77c4706c in emulator.exe: 0xC0000005: Access violation reading location 0x03216848"
The emulator runs normally without "-data" option.

Is there a way to reload an Android application in the emulator without closing the emulator, saving any code changes, and running the emulator again? If I make even a simple change to the layout, it takes about 30 seconds by time I run it in Eclipse and Android "boots", and I can unlock the emulator to run the application. Is there any way to shorten this time when making changes, or is it something I just have to deal with?

I downloaded the most recent version of Android for linux (android-sdk_r05-linux_86.tgz). I was trying to use the the Android Ant task(s) for packaging, building, and deploying my code. I should mention that I'm running AMD64, but have the 32-bit libraries installed. The Android Ant tasks are all broken.
First, the start-emulator task never gets the emulator running. It does get past starting adb, but then just sits there.
Second, the SDK is missing the aapt binary in the tools directory. So, the example notepad sample application will not even package correctly.
I have all the dependencies configured for Android. I can run it from the command line just fine.I assume the Ant code is out of sync with the recent SDK updates. Can anyone shed some light on this problem? At this point, I'm considering writing my own Python scripts to interact with the Android SDK. Ugh.

Just got a HTC Legend and am very keen to get into Android development (having previously been expirenced with eclipse/java/gwt).
However, the USB ADB driver on the SDK doesnt support it, so I wondered how I could add it myself.
I feebly tried adding;

to the inf file. But it didnt help. (mainly because I have no clue what I was doing)

I am currently having issues installing my G1 in development mode on Vista 64 Premium SP1. I have tried both installing the drivers that come with the latest SDK and also the ones here: http://forum.xda-developers.com/showthread.php?t=446274.
Whenever I plug the phone in it comes up as an unknown USB device under device manger. When I go to update driver and point the installer at the correct driver location it either says 'the device driver is up to date' or when using the have disk option it says 'the folder specified does not contain a compatible software driver for your device'.

I have two machines, one a WindowsXP32, and one 64. Both with AMD64 chips. I have eclipse on both, and the SDK on both. I'm using the usb drivers with the HTC Legend (http:// groups.google.com/group/android-developers/browse_thread/thread/ 2b54d2ce1202b04b/dd6f9152cd50d64b?lnk=gst&q=usb+#dd6f9152cd50d64b).
On the 32bit one things work just peachy. Device recognised, and debugging working fine. However, the 64bit one doesn't seem to recognise the device. Windows recognise's the device, and windows device manage shows it, but "adb devices" lists nothing, and nothing shows up when trying to manually launch from eclipse.

I'm trying to use the SWM and when I have everything all set up it tells me I have no device set up. I looked to see if I could find drivers for me Xperia X10 and all I kept getting linked to was the sony PC companion that apparently had those drivers installed. When I installed it and did all the set up stuff it still wouldn't recognize my phone other than as a removable disk. I have the USB debugging turned on, .Net framework installed, and supposed the drives yet it still won't read my phone.

Why isn't Google playing nice with regards to the Linux Kernel Android code? Greg KH says the Android code is stagnant and as a result got removed recently: http://www.kroah.com/log/linux/android-kernel-problems.html
I know for a fact Greg KH bends over backwards to help Linux Kernel developers maintain their code, so hearing this news about the Android drivers being removed is very troubling. Hearing about all the hardware companies that now cannot get their own Android drivers into the main kernel is the worst of it. Google seems fairly evil lately, but everyone who should care (fellow Android developers, I'm looking at you) seems to just want to put their hands over their ears and sing "la la la la".
Android is not being handled in the true spirit of open source, and Greg KH's assessment of the situation is even more proof of that fact.

I have owned my Droid since day 1 and I have been doing Android development, with ADB working, on my Windows 2003 Server laptop all this time. I'll try to be as detailed as possible. Things to note right off the bat: - Motorola Droid 2.1 - Windows Server 2003 laptop - ADB has worked perfectly with this for ~ 8 months My work gave me a HTC Evo to do some development on. I installed the HTC drivers, ADB worked fine, did my development and now I am done with the Evo. The problem is my Droid no longer works with ADB.
