FuzzyLite Use in Android

[Unknown]

Hello, I want to use FuzzyLite on my android project but I didn’t know how to start. Can anyone give an example of android application that uses this library to inspire me?
Thank you.

Hi all, I have compiled on android with native c++ code the library to be used on android but with native interface. I got results with always default value because no rules are triggered. Is there anyone that had same kind of problem? tks

Hi Marco,

the best way to deal with this is to analyse your controller behaviour using QtFuzzyLite.

Cheers.
