Android emulator opengl tracing

[Jakk Wong]

Yes, sorry about that. I meant to say LD_LIBRARY_PATH.

Something that I am trying to accomplish is similar to a demo shown in this
video - http://vimeo.com/28553803 by LunarG. But I am using the emulator
included in the Android SDK with host gpu usage enabled. How might I be
able to do this with apitrace?

Thank you.
