UnsatisfiedLinkError on Lenovo devices.

Hi, we are getting crashes with following Stack Trace:

```
Fatal Exception: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.m360.android-2/base.apk"],nativeLibraryDirectories=[/data/app/com.m360.android-2/lib/x86_64, /data/app/com.m360.android-2/base.apk!/lib/x86_64, /vendor/lib64, /system/lib64]]] couldn't find "libbox-jni.so"

For now this crash happens only on 2 Lenovo devices - "Lenovo YT3-X90F" and "YOGA3 Tablet Pro".

Do you have any ideas why it happens and how it can be fixed?

Thanks in advance :)

Start at BoxPreviewDocumentFragment. on line 66 and inspect how the APK loads libbox-jni.so for the x86_64 paths shown in the trace. Reproduce the crash on the Lenovo YT3-X90F and YOGA3 Tablet Pro devices, then verify that preview creation completes without an UnsatisfiedLinkError.
