Scale down WebView initial scale

I want to scale down my WebView initial scale like to following viewport config:

<meta name="viewport" content="width=device-width, initial-scale=0.93, maximum-scale=0.93, user-scalable=no" />

But this viewport ignored by WebView and rendered as full scale, here is my WebView setting with no success:

    mWebView.getSettings().setLoadWithOverviewMode(true);
    mWebView.getSettings().setUseWideViewPort(true);
    mWebView.setInitialScale(93);

Any ideas how to accomplished this?
