Protect State and Error(Error:before: glError1285)
« on: February 05, 2015, 12:46:45 am »
I have 2 questions.
1. I have 3 main classes. These are extends from Renderer,GLSurfaceView and Activity.  I pause or stop Activity but when I want to resume
texture return to black. How can I fix it?

2. I am  getting error(Error:before: glError1285). I add-remove,replace some textures. I think this error about out of gpu memory. But how can I fix it?

Here is log...

Hard to tell...just try smaller textures and see if that fixes the problem. Are you doing any exotic stuff like calling GL functions directly in your code or are you using this: http://www.jpct.net/jpct-ae/doc/com/threed/jpct/GLSLShader.html#compile(java.util.List)?
Or maybe your texture add/remove/replace code is faulty. If you, for example, assign a texture to an object that the TextureManager knows as "blah" and you remove "blah" from the manager just to add another texture with the same name, your object will still reference the old one. If you are doing something like that, then don't! Use replaceTexture instead.

I can't be bothered to read the whole thing, but this part looks suspicious to me:

...AsynImageDownloader...

An AsynImageDownloader looks quite...async? And if it is, it's not a good idea to replace a texture from outside the rendering thread.
You can load the textures async, but add or replace them inside the rendering thread or you might run into trouble. Just queue these operations and execute them inside the rendering thread.
Apart from that, you are doing quite a lot of unnecessary operations in the onSurfaceChanged-method. All you have to do is to create a new FrameBuffer. You don't have to recreate world and object instances if they still exist.
