addJavascriptInterface() has been around since API Level 1. What you are linking to is the @JavascriptInterface annotation, which has only been around since API Level 17. Neither of these things have anything to do with your problem.

is there anyway to pass a json to javascript?

On API Level 19+, use evaluateJavascript(). On API Level 18 and below, use loadUrl("javascript:"), using the same basic syntax used for bookmarklets on desktop browsers.
