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

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

... 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 ?

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;
}
}


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

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



I reexport model with animation, change manually vertex count again, after that found null pointer in SkinHelper.asArray(mesh.getTextureCoords().get(0).coords)  (BonesImporter.class) - 0-key value some reason was null, get(1) ... and finally i saw model on screen... but as 1 mesh without submeshes. So i hope next release will be better.
But now i solved the problem in next way - bender 2.57 -> collada .dae -> blender 2.49 (with it ogre exporter) -> create bones etc -> make animation actions/ shape keys -> export to ogre mesh
