Fixed! Please Help Me With This Build Fail for hello_xr

Error fixed. I removed 

'arm64-v8a', 

from build.gradle and I added libopenxr_loader.so to all directories containing libhello_xr.so (one of them was the culprit)

So I'm trying to get hello_xr to run in Android Studio but it keeps failing and giving me this big error. I can't figure out why I'm getting the error. It shows that  java.lang.UnsatisfiedLinkError: Unable to load native library "/data/app/com.khronos.openxr.hello_xr.opengles-tIYUBycymObNaVjujvzClw==/base.apk!/lib/arm64-v8a/libhello_xr.so": dlopen failed: library "libopenxr_loader.so" not found, but I can't find the directory that the error is referring to.  

Update: I added  all the directories libopenxr_loader.so to all the directories that contain libhello_xr.so. Now I'm getting this error:
