Quick Start

To open a new webview, just call in your app's js:

    webview.Show(URL);

Where URL is the path to the page to be opened. In Android, the plugin automatically adds the prefix file:///android_asset/www/ But only if no *:// or javascript: is present at the front of the URL.

Then, to close the second webview and return to the main view, call in your second webview (the opened webview, not the main webview):

    webview.Close();

This will close and destroy the second webview.

webView

The webViewobject provides a way to manage a second webview inside your cordova app. This could be usefull if you want to open a second page as a popup or you want to load new content that is totally unrelated to the main view, but still have the ability to use cordova plugins.

The main difference with inAppBrowser plugin is that cl.kunder.webview plugin can access and use all cordova plguins installed in your app.
