mraa demo crash

Hello,

I am using ROCK PI 4B with Android 10.

I am trying to use the Mraa library to drive the GPIO. But it keeps crashing when calling the Gpio.write() or Gpio.read().
It only gives error like
A/libc: Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x10 in tid ...

I also tried this demo program. The result is the same.

libmraa.so not found

Hello,

When I clone and try running this project in android studio, I get the following error:

W/System.err: Native code library failed to load.
java.lang.UnsatisfiedLinkError: dlopen failed: library "libmraa.so" not found

Is there a separate libmraa.so lib that should be downloaded for use with the included libmraajava.so in mraa-2.1.0.arr?

Thanks,
Akin
