This is forked project from https://github.com/moderna/cordova-plugin-cache for clearing WebView cache. For android it deletes the cache folder (total clear of cache).

There is one method:

• clear(successCallback, errorCallback)

You may use phonegap CLI as follows:

➜ phonegap local plugin add https://github.com/moderna/cordova-plugin-cache.git
[phonegap] adding the plugin: https://github.com/moderna/cordova-plugin-cache.git
[phonegap] successfully added the plugin

document.addEventListener('deviceready', onDeviceReady);
function onDeviceReady()
{
        var success = function(status) {
            alert('Message: ' + status);
        }

        var error = function(status) {
            alert('Error: ' + status);
        }

        window.cache.clear( success, error );
}
