opengl es - Android memory mapped file with vertices -

-

i trying render vertices stored in big file (approx 50mb). file layout optimized can take slice , give opengl render triangel strip directly.

this works in emulator, when run same code in magic (android 1.5) crashes sigbus in libhgl.so. sounds driver issue?

i have tried manually copy vertices local buffer (non mem mapped), works takes eons of time, 300-600 ms.

anyone have experience?
