Android Port

[SethRobinson]

Proton uses STL and BOOST which is not properly supported by the official NDK r5, and even when using the Crystal fork of the NDK it doesn't work. In other words, it is very hard to get that up and running for Android.

Is there any simple tutorial/step-by-step description how to compile the Irrlicht GLES branch under Windows for Android?

Just an update, I've updated Proton's Android stuff so it now only uses the vanilla Android NDK r6 (no Crystax) - New tutorial on setting it up here: http://www.rtsoft.com/wiki/doku.php?id= ... roid_setup

Hi!
I am having trouble running Irrlicht with GLES 2.0. I added the missing shaders, and i have a valid GLES 2.0 Context. But when in the COGLES2Driver.cpp in line 1593:
MaterialRenderers[Material.MaterialType].Renderer->OnRender( this, video::EVT_STANDARD );
gets called. The Application dies with Signal 5. I am not debugging, so i wonder where this comes from.

Any hints?

[marwee]

For anyone also receiving this Error on Tegra 2: The reason the Application crashed was that Irrlicht intented to set a uniform array, that was optimized away. The size of all Uniforms with MAX_TEXTURE_UNITS Length was shortened from 4 to 2 because the shader never uses for example uUseTexture[2] or higher. The nicest workaround i found was setting MAX_TEXTURE_UNITS to 2 in the COGLES2FixedPipelineShader.h and also in the 2 Shader files. After that you can leave the shaders unmodified and everything works. But disappointingly slow compared to the GLES 1 Renderer.

Hy,

I have a problem with the GLES 2.0 driver. It does not load my textures. GLES 1.0 works fine with the same textures.
I have a LG Optimus Black.

Anyone know what is the solution to this problem?

[mixa]

Thanks for the port.

apk sample files from http://www.scigems.org/downloads/ works OK on my NookColor. I tried to build the port myself from sources, built OK, but it fails at run-time on device with this trace:

I think that all files on sdcard are in place, since prebuilt apk run OK.

I'm completely new with Irrlicht - could somebody give an idea what the matter can be? I saw in this forum that quake example runs even in emulator with Open GL ES 1, but my build is for ES 2 - can it matter? How to switch test build to use ES 1 driver instead of ES 2?

Thanks in advance
Mike

[mixa]

Yes, the problem was in ES 2 driver - changed to ES 1 and it works OK now

Hey hey - saw this thread ages ago but never really cared for it since I didn't have an android... now that I do however - i'm interested! I've been dinking around in Java with jpct-ae, libgdx and even raw Opengl. I cannot find a new framework/engine to really call my home, Irrlicht's 3d scene graph is trumps anything i can find. Closest to a 3d scene graph is jpct-ae and even then it feels incomplete. I've worked with Irrlicht for years now, from games to editing an old PSP port's version of Irrlicht to do what i need. I know it quite well...

I'm really tempted to just stick with Irrlicht even for android, but I can't seem to find a clear, concise sample. Proton SDK looks promising, but it looks like another abstraction layer on top of Irrlicht... Java's garbage collection scares me as well which just pushes me back towards C++ even more..

tl;dr ---- Has anyone compiled together a simple Irrlict-for-android eclipse/vs/dev-c++/w.e project? Is irrlicht on android demonstrating equal frame rates as native java 3d frameworks? Thanks heaps!

Hy,

I have a problem with the GLES 2.0 driver. It does not load my textures. GLES 1.0 works fine with the same textures.
I have a LG Optimus Black.

Anyone know what is the solution to this problem?

I have the same issue. GLES 1.x OK, but GLES 2.0 cant apply texture. I am currently trying to find the answer, and anybody could give some advice. Thanks in advance.

[SG57]

That's interesting considering I can't get OGLES 1.x to bind textures, havent tried 2.0. Did you have to make any adjustments to your irrlicht compilation to get textures working for 1.x? What version of irrlicht - 1.7-beta ?

[skreamz_]

okay guys, just thought others might like this

you will have to change a few thing in the code to get it to work.
also you will need minizip from the zlib download its in the contrib folder of the download

just so you know this code removes the need to write the data to sdcard before loading it. it opens the apk file which is a jar file renamed.

you can use the loader via

Code: Select all

 
device->getFileSystem()->addArchiveLoader(new JarReaderLoader(device->getFileSystem()));
        
device->getFileSystem()->addFileArchive(gapkPath.c_str());
 

and you can get the apk path from the java side

Code: Select all

 
        PackageManager packMgmr = getPackageManager();
 
        ApplicationInfo appInfo = null;
                try
                {
                        appInfo = packMgmr.getApplicationInfo("package.name.goes.here", 0);
                } catch(NameNotFoundException e)
                {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                }
        String apkFilePath = appInfo.sourceDir; 
                
        nativeEnvJ2C(Environment.getExternalStorageDirectory().getAbsolutePath(), apkFilePath); //added the perimeter and sent it along to cpp
 

have fun..

[tonic]

You can just open the apk as a zip file with the default zip reader.

[skreamz_]

ive tried that, the irrlicht zip reader seems buggy and does not locate all of my files within the apk file.
