API can only be initiated by a user gesture

[incafox]

Hi everybody, i have a problem sending a click button order with .evalJavascript method, it show me:
[INFO:CONSOLE(1)] "Failed to execute 'play' on 'HTMLMediaElement': API can only be initiated by a user gesture.
i know in java android i can make something like this:

WebView mWebView = (WebView) findViewById(R.id.web_view);
mWebView.getSettings().setMediaPlaybackRequiresUserGesture(false);

so, the question is how to disabled this petition?
