javascript - phonegap/cordova onDeviceReady() 不触发 android 4.1.2

Question

我已经束手无策了。我正在使用 Adob​​e Build 和 PhoneGap 版本 3.5.0 以及 Cordova 3.4.0。

无论我做什么，我的 onDeviceReady() 事件都不会在我的 Android 设备上触发，无论是作为 APK 还是在 PhoneGap 开发者应用程序中。

这是我的 config.xml:

这是我的 index.js 文件，其中包含 deviceReady 处理程序。这对于 iPhone 来说效果很好。

var app = {
    // Application Constructor
    initialize: function() {
        this.bindEvents();
    },
    // Bind Event Listeners
    //
    // Bind any events that are required on startup. Common events are:

    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);
    },
    // deviceready Event Handler           
    onDeviceReady: function () {
    itDoesntMatterWhatIsHereItDoesntFire();
    },

在 header 中调用 app.initialize() 并不能保证页面已准备就绪。尝试将其添加到正文的 onload 属性中:

<body onload="app.initialize()">
