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.
-
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.
-
I still don't get it... ???
-
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() {
return = new MyEngine();
}
//in engine
onCreate(){
executor = Executors.newSingleThreadExecutor();
}
onDestroy(){
executor.shutdownNow();
super.onDestroy();
}
onSurfaceCreated(){
//init gl/egl
EGLConfig config = null;
egl = (EGL10) EGLContext.getEGL();
glDisplay = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY);
int[] version = new int[2];
egl.eglInitialize(glDisplay, version);
int[] configSpec = new int[]{EGL10.EGL_DEPTH_SIZE, 16, EGL10.EGL_NONE};// {EGL10.EGL_RED_SIZE, 5, EGL10.EGL_GREEN_SIZE, 6, EGL10.EGL_BLUE_SIZE, 5, EGL10.EGL_DEPTH_SIZE, 16, EGL10.EGL_NONE};
EGLConfig[] configs = new EGLConfig[1];
int[] numConfig = new int[1];
egl.eglChooseConfig(glDisplay, configSpec, configs, 1, numConfig);
config = configs[0];
glc = egl.eglCreateContext(glDisplay, config, EGL10.EGL_NO_CONTEXT, null);
glSurface = egl.eglCreateWindowSurface(glDisplay, config, holder, null);
egl.eglMakeCurrent(glDisplay, glSurface, glSurface, glc);
gl = (GL10) (glc.getGL());
//create renderer
renderer = new MyRenderer();
renderer.onSurfaceCreated(gl, config);
//in renderer.onSurfaceCreated create word, textures objects etc
}
onSurfaceDestroyed(final SurfaceHolder holder) {
super.onSurfaceDestroyed(holder);
egl.eglMakeCurrent(glDisplay, EGL10.EGL_NO_SURFACE, EGL10.EGL_NO_SURFACE, EGL10.EGL_NO_CONTEXT);
egl.eglDestroySurface(glDisplay, glSurface);
egl.eglDestroyContext(glDisplay, glc);
egl.eglTerminate(glDisplay);
mVisible = false;
}
// on surfaceChange & onVisibilityChanged has only logic for call draw command in executor
-
What kind of "crash"?
-
ERROR/Surface(239): surface (id=0, identity=22) is invalid, err=-19 (No such device)
and black screen wallpaper
-
What i should destroy from jpct part in onSurfaceDestroyed() of Engine ?
-
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.

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

Is this code:
if(world!=null){
world.removeAll();
world.dispose();
world = null;
}
still in place and called?
-
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
public void release() {
System.out.println("Clear renderer");
if (world != null) {
world.dispose();
world = null;
}
if (fb != null) {
fb.dispose();
fb = null;
}
}
-
aaaaaaaaaaaaaaaaaaaaaaa, i forgot world.removeAll(); :) , trying with it
-
I was about to suggest this... ;)
-
... only 4 running, the same. :'( I try
TextureManager tm = TextureManager.getInstance();
Set<String> names = tm.getNames();
if (names != null && !names.isEmpty()){
for (String name : names){
tm.removeTexture(name);
}
}
but then, when textures remove and next create command trying set their - throw exception about textures allredy exists.
How i can clear TM singleton ?

The question is: Why would you do that? Actually, you don't have to. Just load the textures once and don't touch the manager's content afterwards. Just make sure that you don't load them on each new surface creation. But to answer your question: http://www.jpct.net/jpct-ae/doc/com/threed/jpct/TextureManager.html#flush() (http://www.jpct.net/jpct-ae/doc/com/threed/jpct/TextureManager.html#flush()). Ignore the comment about applet in the Javadoc of that method. It's a porting flaw from desktop jPCT. I'll remove it.

dont help.
if use this removing
if (fb != null) {
System.out.println("************************************ remove textures");
TextureManager tm = TextureManager.getInstance();
Set<String> names = tm.getNames();
if (names != null && !names.isEmpty()){
for (String name : names){
tm.removeAndUnload(name, fb);
}
}
fb.dispose();
fb = null;
}
first after recreate - ERROR: A texture with the name 'redCell' has been declared twice! - (in try{}catch)
and second, when try set - ERROR: Tried to set an undefined texture as default!

sorry, i don read your last replay, i try create once

You can actually do that for everything as long as you keep the references somewhere. There's no need to load objects and textures on each surface creation. The only thing that has to be recreated each time is the FrameBuffer because it takes the gl context and the orientation might have changed. But apart from that, jPCT-AE will take care to reuse your objects and textures in another context on another surface.

in wallpaper service in oncreateEngine
texturesCreated = false;
...
if (!texturesCreated){
redCell = new Texture(BitmapHelper.rescale(BitmapHelper.convert(getResources().getDrawable(R.drawable.red_cell)), 64, 64));
blueCell = new Texture(BitmapHelper.rescale(BitmapHelper.convert(getResources().getDrawable(R.drawable.blue_cell)), 64, 64));
aNuc = new Texture(BitmapHelper.rescale(BitmapHelper.convert(getResources().getDrawable(R.drawable.nuc_a)), 64, 64));
tNuc = new Texture(BitmapHelper.rescale(BitmapHelper.convert(getResources().getDrawable(R.drawable.nuc_t)), 64, 64));
gNuc = new Texture(BitmapHelper.rescale(BitmapHelper.convert(getResources().getDrawable(R.drawable.nuc_g)), 64, 64));
cNuc = new Texture(BitmapHelper.rescale(BitmapHelper.convert(getResources().getDrawable(R.drawable.nuc_c)), 64, 64));
TextureManager.getInstance().addTexture("redCell", redCell);
TextureManager.getInstance().addTexture("blueCell", blueCell);
TextureManager.getInstance().addTexture("aNuc", aNuc);
TextureManager.getInstance().addTexture("tNuc", tNuc);
TextureManager.getInstance().addTexture("gNuc", gNuc);
TextureManager.getInstance().addTexture("cNuc", cNuc);
texturesCreated = true;
}
ERROR: Tried to set an undefined texture as default! - and because that i recreating rextures in onSurfaceCreated

I've no idea when you call onCreateEngine() or what you do when the app goes out of scope...but: If you upload the textures only once and never remove/unload/flush anything, then there is no need to reload them again. Just have a look at the examples that come with the engine: They don't do that! They load everything only once and keep it until the app gets destroyed by Android.

sorry, i dont remove removing textures code, now 6 time without crash :) . Too late, i did not realize anything now, this wallpaper make me crazy :) I will continue tomorrow
-
I move all textures & world initialization to Engine.onCreate, in onDestroy clear world & textures, all work good, but, i worry that if on device installed 2 different applications and some textures has equals names? TextureManager instance will be the same for both?
-
No, it's only a singleton per VM instance.

Ok, thank you for replies!
