Thank you.
Nadro, you published games that use irrlicht on Google Play, right? Can you share with us your way to get the screen resolution when creating the device in jni?

I published games only on AppStore, we'll publish games on Google Play in future, but currently Android port of our games isn't ready.

Oh... so you haven't solved this problem yet? I looked into it, they say the correct way to do this is pass the resolution from java code... no idea how to do that since I only have c++ code.

my 5 cents on how to get screen resolution in android as native app: in CIrrDeviceAndroid.cpp, after APP_CMD_INIT_WINDOW is called, the screen size values is available in android_app. Look for the following code:
After IsReady, use something like the following to get the width/height:
Code: Select all
// Check if screen dimension is set. If not, use size of Android->window.
DeviceWidth = (DeviceWidth > 0) ? DeviceWidth : ANativeWindow_getWidth(Android->window);
DeviceHeight = (DeviceHeight > 0) ? DeviceHeight : ANativeWindow_getHeight(Android->window);
i am new here and good to see an active mobile community in irrlicht. cheers

Thank you, this helped a lot!
I now have a way to determine the screen resolution in a few easy steps. It does require a dummy device, but that's quite ok as that's the same approach you use on desktop, no engine changes necessary.
Code: Select all
SIrrlichtCreationParameters param;
param.DriverType = EDT_OGLES2;
param.WindowSize = dimension2d<u32>(320, 240);
param.PrivateData = app;
param.Bits = 24;
param.ZBufferBits = 16;
param.AntiAlias = 0;
device = createDeviceEx(param);
int w= ANativeWindow_getWidth(app->window);
int h= ANativeWindow_getHeight(app->window);
device->closeDevice();
param.WindowSize = dimension2d<u32>(w, h);
device = createDeviceEx(param);
Cheers
The best way would still be to do as you said though, I'll try it out later

Definitly we should integrate support for it inside engine.

So... after the ISReady line, this code seems to work flawlessly:
Code: Select all
DeviceWidth = (DeviceWidth > 0) ? DeviceWidth : ANativeWindow_getWidth(Android->window);
DeviceHeight = (DeviceHeight > 0) ? DeviceHeight : ANativeWindow_getHeight(Android->window);
CreationParams.WindowSize.Width= DeviceWidth;
CreationParams.WindowSize.Height= DeviceHeight;

Any idea when we could get OpenGL ES 3.0 driver?
Handle Andoid EGLContext losing

@Nadro:
When Activity onPause, the EGLContext is lost, and all textures and VBO are invalid. Any way to handle it on Irrlicht? Now the HelloMobile sample is black after press Home key and return to app.

I guess you have to handle it yourself and re-create the whole device. There is a functions you can implement and then set:
http://developer.android.com/reference/ ... ivity.html
Code: Select all
android_app* state;
...
static void engine_handle_cmd(struct android_app* app, int32_t cmd)
{
//handle command here
}
...
state->onAppCmd = engine_handle_cmd;

Both OpenGL 3.3 and ES3.0 should be available before end of this year in shader-pipeline branch.
@penguin03
What about context lost on Android? Android 4.0+ is able to hold context, for older Android versions you have to recreate data manually as ent1ty.

@ent1ty
You are right, we need to re-create the whole device, it's a little tough to restore the game state after re-create the whole device. I'll try it.
@Nadro
The OpenGL es context holding depends on Hardware driver. Not all Android 4.0 + device can support it. I use Samsung Galaxy Note II to test the the HelloMobile sample, it can't support it, its Android version is 4.1.2.

Yeah, same on Nexus 7 with android 4.3
Edit: this looks interesting:

Does irrlicht already do this?

Irrlicht need some changes to support GLSurfaceView as alternative for EGL window created from C++ code.

I'm getting quite horrible seams using the OGLES2 driver:
On desktop there are none to barely noticeable ones(OpenGL), any advice on how to get rid of them?
Edit: my near/far values are 1.0/1800.0, i tried increasing the near value to 100.0, still didn't really help
Edit 2: I tried adding glClearDepthf(1.0); to the if (zBuffer){ ... } block in beginScene, as described here:
http://stackoverflow.com/questions/1183 ... sing-glkit (thanks Strong99) but it doesn't seem to help in any way. I'm not feeling particularly 'at home' with editing irrlicht source, am I doing something wrong?
