Error about unmapping

Hi, 

I got these errors every time I quit the app.

What does these errors come from?
 
Thanks

For the unmapping errors, these can be caused by a variety of components in Android

Is there any specific libraries or other components (not Vuforia) that you are using ? maybe one thing you could do is try to isolate the problem by selectively disabling some of the custom code / components and see at which point the error message shows up.

Hi,

I've detected  some OpenGL operations that called outside the OpenGL thread. The error about that has been solved. But the unmapping errors still unsolved.. Do you have any idea about this?

Thanks

Well, the error log shows that you are doing some OpenGL operations outside the OpenGL rendering thread, i.e. without a valid OpenGL context.

Have a look at this article for clarifications on the threading topic:

Hi, 

I'm using ImageTarget, but with some modifications. I put lighting with my own shaders, disable the textures, and changing the virtual content. Are they related to these errors?  the modifications  work without any problem except for these errors.

Hi, which app does it happen ? one of our samples or your app ?
