Answer 1

OK, here's an example of interacting with the javascript interface...

Setting the javascript interface in your Activity...

JavascriptInterface javasriptInterface = new JavascriptInterface(this);
webview.addJavascriptInterface(javasriptInterface, "Android");

The inner JavascriptInterface class in your Android Activity...

public class JavascriptInterface {
    Context mContext;

    JavascriptInterface(Context c) {
        mContext = c;
    }

    public boolean doSomething(String name, String address) {
        ...
        return true;
    }
}

EDIT: Your form will have various input fields. Example...

<form name="myForm" ...>
    <input type=text name=personName>
    <input type=text name=personAddress>
    <input type="button" value="Do it" onClick="callDoSomething()" />
</form>

<script type="text/javascript">
    function callDoSomething() {
        var theName = document.myForm.personName.value;
        var theAddress = document.myForm.personAddress.value;
        var result = Android.doSomething(theName, theAddress);
    }
</script>
