slow reload after onResume

[pepposole]

Hello!

I'm developing a live wallpaper using this wonderful extension but i'm stuck trying to optimize reloading time
after a onPause triggering event (like screen locking or simply executing an application) and relative onResume.

When onResume is triggered, it takes 2-3 seconds to start animations (particles generator + registerEntityModifier applied to a sprite).


any advice to improve this "start-up" time? I got some opengl live wallpaper installed (like Jungle Waterfall) and it takes no time to resume animations so i guess i'm managing my wallpaper textures in a wrong way.

Thanks in advance

I noticed it takes 1,5 seconds on TextureManager's updateTextures function.

i think loadOnHardware is the time-consumption function.


what does it happens when live background loses his focus? every texture is unloaded from hardware?

if it doesn't, is it possible to check if textures are still in hardware memory before load them again?


i'm trying to figure out how to do it but i'm too noobie

Did you find any solution to this?

I'm having the same issue with orientation changes. It does not make too much sense to re-upload all the textures on onResume, if there where a close ok you have to but without?

This has been suggested in another post:

I guess we need to create a new BaseLiveWallpaperEngine that does not call on the Engine.onResume()

Someone correct me if I'm wrong; I haven't done a wallpaper before...

If you don't pause the engine when the activity is paused, that means the engine will continue running and taking up CPU even when the wallpaper isn't displayed on the screen anymore. Your users might not be impressed about that.

I was a bit unclear, I meant a new BaseLiveWallpaper class that does not call the onResume() in Engine.java:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

1. public void onResume() {
2.                 // TODO GLHelper.reset(pGL); ?
3.                 this.mTextureManager.reloadTextures();
4.                 this.mFontManager.reloadFonts();
5.                 BufferObjectManager.setActiveInstance(this.mBufferObjectManager);
6.                 this.mBufferObjectManager.reloadBufferObjects();
7.         }
