I am not sure if our demo apps still work with Android 6, which was released in 2015. Have you tested the demo apps on some other devices? Moreover, we also provide some prebuilt arm64 apk, can you try the apk?

Another possibility is that your device has armeabi-v7a CPUs and android_arm64 setting is not working on your device.
