How to call native function from cordova 3.x

Question

How can I call a native function from cordova/phonegap webview for example for showing an ad.

EDIT: OK I FUNALLY GOT IT and I\'m gonna write some steps for all of y

Answer 1

In the .java file

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    super.init(); // Calling this is necessary to make this work

    appView.addJavascriptInterface(this, "MainActivity");

    super.loadUrl(Config.getStartUrl());

}

In the javascript

window.MainActivity.customFunctionCalled();

This will only work on TargetSDK<17 . An androidManifest.xml targetSDK need to be set < 17. And for TargetSDK >=17 , I guess you'll need to create some custom plugin. I use this process lowering my target SDK for now.
