When launched, Tango Core crashes, followed by HelloAR itself

Doesn't look like it'll help much, but here's the log from HelloAR.
Maybe Vulkan related?

Thanks for your report. I added it to the research document to try to isolate the issue. Let's collect more info and try more modifications.

[szugyi]

Unfortunately I had the same result with LG G3.

[szugyi]

I think the root of these kind of issues is the lack of support of 32bit processors.
After opening the arcore-preview.apk I have noticed that the lib folder contains both an arm64-v8a and a armeabi-v7a folders, but the armeabi-v7a has only 1 file while the other has 9 of them, one of them being the libtango_hal.so.

[tomthecarrot]

@szugyi That's an interesting point. I added the processor architectures for each phone to the device research doc. There doesn't seem to be a meaningful correlation between processor architecture and support, beyond the fact that no 32-bit phone we have tested as a community has worked (which you alluded to in your last comment).

It's a beneficial discovery though, so thank you for adding it here! I'll add a 64-bit processor as a prerequisite to the README so new users know.
