title: android opengl texture loading thread
body: <p>I'm working on an app that needs to load textures for frame animations at certain times while it's executing, the rendering thread needs to continue to run and I need to load the textures in a bg thread. Is there a way to do this in android?  I was able to in ios by creating a separate opengl context on the other thread that used the same sharegroup but am not sure if there is a similar facility on android?</p>
