No idea? I left my (Project Settings - Platforms - Android SDK) NDK API Level to android 19 and I left my (Project Settings - Platforms - Android) Minimum SDK and Target SDK to both be 9? The first time I installed API 23 I used SDK Manager which didn’t work. I had to install it with NVPACK\Chooser and switched the dropdown to “CodeWorks for Andoid 1R6u2” As for some reason I don’t have the 1R6u1 option. Once I got past this error, I also had to point my Java version to 1.8 due to another error I got later in the compile.
