Hi David,

The instructions say
"After Android Studio is installed, *use it* to install the Android SDK and
NDK."

It also says
"Install the desired SDK Tools. CMake and the *NDK* are the main ones."

It sounds like those statements needs to be changed.

The instructions also say
"For the NDK Get android-ndk-r13b-linux-x86_64.bin and install it in
~/android *too*."

That "*too*" implies that r13b also needs installed in ~/Android/Sdk/ as
nkd-bundle?

You are building it for Android version 26 (Oreo), right?

Thank you for your help with this!

John
