The sample application crashes over signal 4 (SIGILL), code 2 (ILL_ILLOPN) when run on an x86 AVD.  I tried both a Nexus 5 AVD and a Pixel XL AVD at API levels 22 and 25, and the same crash occurs on both as soon as the sample app tries to engage the native GNSDK libraries in onCreate().  It looks like libgnsdk_storage_sqlite.3.12.1.so in particular may be the culprit, judging from the backtrace.  The same crash occurs in my own application when I engage the GNSDK native libs for x86, so the problem is not unique to the sample app.  What can we do about this?

 

I've confirmed that the sample app works on arm hardware and an arm AVD.  I don't have any x86 hardware, so I can't confirm whether this is truly an x86 ABI issue or some oddment with AVDs vs. real hardware.
