mhhh you seem to use a texture that is not loaded by JME’s assetManager, but by android. Android may recycle the memory allocated to resources when your activity is paused. That’s probably what’s going on here.



Why don’t you load your textures with the assetManager?

I just try a model without texture and it's ok now.
But if i import a model with SDK, it will be crash. The texture goes into models automatic and i do nothing with the texture in my code.
Did i misunderstand import Model in the SDK?

What is your model? a j3o?

Are you using the nightly/SVN version of jME3? This was fixed recently.
