Hi guys! I’ve just downloaded the app from https://developer.tizen.org/documentation/articles/working-web-audio-api  and example source code (soundplayer.zip) didn’t launch success. The error is: “tizen is not defined”. What’s wrong with it? I use Tizen SDK 2.2.1.

The error appears after this code: 

        try {
            tizen.filesystem.resolve('music', onMusicResolveSuccess, onError); //this line
        } catch (e) {
            tlib.logger.err(e);
        }
