clear data

[jms]

Hi,
I have a similar problem to post the 12th October "Not Able to clear the data, but can not get me work.

I'm using the libraries in a live wallpaper. If I give a set wallpaper, before it has finished generating the scene and show the preview, then either make an application crash or shows me with malformed elements. For example, a textured Primitives.getPlane, I get only a blank background.

I put the trick mentioned in this post, before this code called by OnDestroy, but does not work:

if(world!=null){
            world.removeAll();
            world.dispose();
            world = null;
}

could someone help me? thanks!

I don't see a relation between your problem and the post you are refering to. Can you explain what you do in a little more detail? Apart from that: This workaround isn't needed anymore.

[jms]

Hi,

When you choose the wallpaper to see it, takes a few seconds to display, if before the end I give the button Set wallpaper for my screen, then crash the application.

For the logs I'm seeing, it looks as if it began to remove items before calling internally and to clean onDestoy world. I do not know if there is a way to stop all creation environment before it is finished. I do not know exactly how to explain.

Thanks.

[EgonOlsen]

I still don't get it...

[Kaiidyn]

if(object != null){ remove object; } in your cleanup.

I have the same problem, second run onCreateEngine() of wallpaper service crash;
Somebody can tell right initialization/destroy sequence?
I try next -

onCreateEngine()  {

egl.eglDestroyContext(glDisplay, glc);
egl.eglTerminate(glDisplay);
mVisible = false;
}
// on surfaceChange & onVisibilityChanged has only logic for call draw command in executor



[EgonOlsen]

What kind of "crash"?

[Alexey]

ERROR/Surface(239): surface (id=0, identity=22) is invalid, err=-19 (No such device)
and black screen wallpaper

[Alexey]

What i should destroy from jpct part in  onSurfaceDestroyed() of Engine ?

[EgonOlsen]

Android destroys the gl context und surfaces itself. The engine contains no code to deal with that and it doesn't have to. What you can do in the engine, is to clean up some memory or maybe unload data from the gpu as long as the context is still valid, but that can't cause nor avoid your problem. Your problem seems to be related somehow to your surface setup code and that's out of the scope of jPCT-AE.

[Alexey]

Now, when i go to preview wallpaper 2nd time, i have java.lang.OutOfMemoryError.

Is this code:

            world.removeAll();
            world.dispose();
            world = null;
}


still in place and called?

[Alexey]

this method now used for clearing. I refactor some in object building (use clone) and now on 4th running  memory out, so objects dont removing
