Answer 1

Using a Cordova Plugin is the recommended approach to expose Java code to the JavaScript layer of your application. Take a look at the Plugin Development Guide and Developing a Plugin on Android .

addJavascriptInterface is part of Android WebView API and it's used inside of Apache Cordova's Android code . There's at least one bug with Android 2.3 and that method you can avoid by using Apache Cordova's plugin system.

What is the diferences using plugin or appView.addJavascriptInterface?

The difference is a Cordova Plugin is a higher level abstraction that allows you to consistently expose native code from various platforms (Android, iOS, among others), to the WebView running your JavaScript code. While the addJavascriptInterface is an Android-specific method that is part of the WebView API which is used Apache Cordova's Android code.
