vine.co is https protocol.

Please find google search for "webview https"

or

Add this overriding method to your WebViewClient implementation. You'll need to compile it with Android SDK 2.2 (API level 8) or later. The method appears in the public SDK as of 2.2 (API level 8) but we've tested it on devices running 2.1, 1.6 and 1.5 and it works on those devices too (so obviously the behaviour has been there all along).

@Override

public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {

handler.proceed(); // Ignore SSL certificate errors

}
