After a long search I got a blog that has complete webview app development series videos, pictures, text tutorials guidelines and codes. In this example: 1. Opening url in webview and show progress for particular page. 2. Show file chooser for Webform file option.
Please let me know what's wrong with this. Working hardcoded code:
I'm trying to use the new evaluateJavascript method in Android 4.4, but all I ever get back is a null result:. webView1.evaluateJavascript("return \"test\";", new ValueCallback() { @Override public void onReceiveValue(String s) { Log.d("LogName", s); // Log is written, but s is always null } });
Loadurl (string url, map < string, string > additionalhttpheaders): load the specified url and carry the http header data.
