Android and Ogre Wiki Tutorial Framework

Post by celticsoul » Mon Feb 18, 2013 5:44 am

I have successfully compiled Ogre for android in my ArchLinux and SampleBroswer works fine on my phone. I've been struggling to get the Ogre Wiki Tutorial Framework (MinimalOgre) to work on Android and the SampleBrowser code is too complicated and mixed with code for other platforms.
Any tutorial to show how to display a simple ogrehead.mesh on Android would be great help.
Thanks.

Murat started some days ago on two Ogre Android samples that should soon be found in the official Ogre repository for you to have a look at. But they will still use the SampleBrowser as the foundation.

Nope the two samples do not use any code from the samplebrowser :) so the are really self contained and simple and just showing one mesh.

While waiting for the new samples in the repo, can someone help me with this problem:
My app crashes whenever I call root->initialise

Code: Select all

void android_main(struct android_app* state)

	// Create application object
	MainApplication app;
	app_dummy();

Ah, then I misunderstood you earlier. Even better for the thread opener ;) .

The code you post can not work at this point you do not have a valid surface to render and there is more wrong the best thing would to wait until the SDK is released (its already done) so you can use it as a base app.

Same question here, have to start a new project on Android. Any idea on the "release date" so that i can plan my work ?

Thanks !

I have also been trying to create a minimal ogre application (no input, just showing a mesh on the screen) running on android. I painfully went through the code of the SampleBrowser and extracted what I thought to be the minimal code needed. By combining it with the android native application example I have ended with the following (in one big file) :

Code: Select all

What is strange is that the application runs correctly and even displays a red screen (I changed the background color of the viewport to see if ogre was doing anything). But I cannot see any of the meshes created in the scene. The log does not report any error apart from the usual plugins.cfg being not found. I feel like I am just missing something simple. I managed to get something displayed once but could never reproduce.

Any help would be greatly appreciated, otherwise I guess I will be waiting for the official minimal application to be released.

Below there is the log.
Also for my any error and I see a red background but no 2D background with a texture and no ogrehead.mesh diplayed.

What am I doing wrong?

You aren't going to see anything just by dropping an entity in the scene, as GLES2 has no FFP. So you either enable RTSS or use a material with your own shaders. There's a thread where robert was kind enough to show a code example for initializing RTSS, so you don't have to dig through the samplebrowser ... let me see ...

Many thanks! That worked! I've got my test apllication running and rendering properly.
I'll go to document myself on the topic in orther to understand better the use of the RTSS.
If you have some reccomendation I'll appiciate it!

I didn't understand at first that RTSS is used for FFP emulation ... basically what it means is that if you just want to use material files and not create shaders by hand, you can do that in your GLES2 app. That's definitely the easiest way to get up and running in a project, and a testament to the awesomeness of RTSS. In terms of creating custom shaders with RTSS I know very little, as I've been using GLSL for shaders and not using RTSS in my current project.

Same question here, have to start a new project on Android. Any idea on the "release date" so that i can plan my work ?

Thanks !

Have been published the source or the samples?? it would be very very helpful since I'm trying to show a mesh in android and it is not working :(

You can easily get it working yourself ... the example is 99% and the other 1% is right here in this thread and the thread that was linked. Just take the time to read and understand.

Ok, I have a ogre floating head , and even it reacts on touching the screen! :D
Buuuut... The head is white, it has no texture, how can I load it? Did I miss something?

I put an example in this thread since for some reason it looked more related to JNI development: http://www.ogre3d.org/forums/viewtopic.php?f=21&t=78160

You probably didn't load the material that the mesh is using. Use adb logcat to check your app's output for exceptions, etc
