Android ARM64

[ickydime]

Since UWP is not supported I can't build to the Hololens. Instead I figured I'd try Magic Leap, given you support Android.   Unfortunately, when I deploy using armeabi-v7a, the app throws errors saying libOni is x86 and needs to be x64.

Would it be possible to get a x64 bit of the Android .so to test it out?   

I requested more details from MagicLeap as well: https://forum.magicleap.com/hc/en-us/com...to-Request

I've seen other 3rd party libraries provide the following in case it is helpful: aarch64-linux-android


Cheers,

Mark

Magic leap responded with a bit more detail in case it helps:

"The Magic Leap dev tools and user apps on device are 64-bit only. `aarch64-linux-unknown-gnu` or `aarch64-linux-android` (in a pinch) would be the expected targets. Hope this helps!
 
We also have some security flags that should be applied for best results:
CFLAGS=-march=armv8-a -mcpu=cortex-a57+crypto -fPIC -fpic -ffunction-sections -funwind-tables -fstack-protector-strong -no-canonical-prefixes -Wa,--noexecstack -Wformat -Werror=format-security

Obi 4.0 supports 64 bit ARM. It will be out in a couple weeks at most.

Fantastic, thanks!
