将我的cordova从 3.1 升级到 3.4 后，cordova API无法正常工作，并且未通过API变量的ReferenceError。

错误消息：

未捕获的ReferenceError：未在文件中定义连接：///android_asset/www/index.html

    // Wait for device API libraries to load
    //
    document.addEventListener("deviceready", onDeviceReady, false);

    // device APIs are available
    //
    function onDeviceReady() {
        checkConnection();
    }

        function checkConnection() {
        alert("on check connection");
            var networkState = navigator.connection.type;

            var states = {};
            states[Connection.UNKNOWN]  = 'Unknown connection';
