Out of memory when load 3ds file.

[androidman]

Hi guys,

I created a teaport with 3ds Max, then export it to .3ds file.
On Android, i load that 3ds file to display. The teaport was displayed, but after a while, the error happened.

on LogCat, i saw this message appeared about 2116 times:

03-17 08:44:52.635: INFO/jPCT-AE(xxx): Additional visibility list (xxxx) created with size: 512

Here is my code:

how can resolve this?

[androidman]

this is my mistake!

I didn't use fb.display() in onDrawFrame function
