WebView returns bad window.innerHeight

Question

I have an application that makes use of the Android WebView, as well as some JavaScript. When my WebViewClient calls onPageFinished(), I alert my JavaScript to run

Answer 1

I used this:

Java code in Activity:

webView.addJavascriptInterface(new WebAppInterface(this), "Android");

...

public class WebAppInterface {
    Context mContext;

    WebAppInterface(Context c) {
        mContext = c;
    }

    public int getWinHeight() {
      return webView.getHeight();
    }
}

JS code:

var winHeight = Android.getWinHeight();
