(the
doc you are using already)
in -DANDROID_ABI select only "armeabi" (remove the other ABI)
Make sure to disable the optimizations:
-DANDROID_OPTIM_NEON
-DANDROID_OPTIM_ARM32
These things are an optional part of the ARM spec and not every chip
manufacturer decides to include them in their CPUs. If you try to run code
using these instructions on a CPU that doesn't support it, Linux kernel
will kill your process with an invalid instruction signal - typically
either SIGBUS or SIGILL => app crashes without any messages. You should
check the log viewer in Eclipse (don't forget to disable any filters!) and
look for a crash there.

Well, I don't want to sound too harsh, but if *you* don't have time to
actually read the documentation and go through the tutorials, why do you
think people on the list should have time to support you? Especially as the
question above is really a FAQ issue that was addressed on the list in the
past. Also basic things like actually checking why it crashed in the log
and finding the stack trace are well documented in the Android SDK/NDK
documentation. We have our own jobs to do as well, you know.
Best regards,
Jan
