问题描述：

使用 ionic3.4.0 创建的 ionic项目（其中Android框架6.2.3版本、AngularJS框架4.1.2版本、Cordova源码JS端6.2.3版本）

使用ionic cordova build android生成apk安装包。

运行apk安装包启动页面动画等待3秒，之后页面白屏5秒。共计启动页面需要8秒的时间。

结论：程序运行启动需要8秒，用户体验无法接受。

1、可能引发该问题的X因子集合

Cordova桥JS端源码（AngularJS 3.2.0版本）
Cordova桥android端源码
cordova-plugin-splashscreen插件源码

2、使用f方法针对X因子进行测试验证

2.1 验证cordova-plugin-splashscreen插件是否是关键因子？

验证方法：
- 使用ionic cordova plugin删除 cordova-plugin-splashscreen插件，并删除JS端相关的splashscreen的调用方法，运行应用，查看效果；
验证效果：
- 启动动画页面消失，白屏5秒进行应用；
结论：
- cordova-plugin-splashscreen对控制启动页面动画。（该3秒的时间可可以通过修改config.xml里的 SplashScreenDelay 来控制时间长短。）

2.2 验证Cordova桥android端源码是否是关键因子？

因为ionic1中没有出现此问题，对比了ionic1与ionic3项目中除了AngularJS端的代码差异。

验证方法：
- 使用beyond compare软件对比两个项目的代码文件。
验证效果：
- cordova-plugin-splashscreen、android框架包没有差异。
结论：
- 80%排除原生端代码对该问题的影响。

2.3 验证AngularJS3.2.0是否是关键影响因子？

2.3.1 使用ionic2中的AngularJS 1.5.3 版本进行验证：

验证方法：
- 互换ionic2与ionic3中platforms/android/assets/www目录；
验证效果：

组合方式	ionic版本	AngularJS版本	验证时间
正常组合	ionic2	1.5.3	3秒
	ionic3	4.1.2	8秒
测试组合	ionic2	4.1.2	8秒
	ionic3	1.5.3	3秒

结论：
- 该问题80%的可能性与AngularJS的版本更换内容有关。

3、寻找具体原因

3.1 查看日志是否包含有效信息？

查看android studio输出日志如下：

日志关键词语：
- Angular is running in the development mode. Call enableProdMode() to enable the production mode.-->需要设置AngularJS为生产模式。
- deviceready has not fired after 5 seconds.-->cordova的deviceready消息没有被触发，5秒超时后cordova框架自动发出消息；

3.1.1 验证设置AngularJS为生产模式是否是关键因子？

验证方法：
//测试方法：在main.js添加以下代码：
import {enableProdMode} from '@angular/core';
enableProdMode();
验证效果：
- 启动应用仍然需要8秒；
结论：
- AngularJS的生产、开发模式不是关键因子。

3.1.2 验证 deviceready 消息超时是否是关键因子？

验证方法：
- 阅读 cordova桥JS端源码，如果deviceready消息超时，会打印出影响超时的模块内容，但是查看日志，并没有输出对应模块的内容。
- 使用AngularJS 1.5.3 版本测试，查看日志；（详细日志见附录5.2）
验证效果
- AngularJS 1.5.3正常，deviceready消息大约3秒左右完成。
- AngularJS 4.1.2不正常，deviceready消息总是超时（原因不明，可能是ionic-angularjs封装时导致了 onDOMContentLoaded 存在问题，测试日志见文档末尾）
结论：
- onDOMContentLoaded 消息存在问题，而AngularJS与onDOMContentLoaded消息有关的模块只有 AngularJS 封装的 platform对象；

3.1.3 验证 AngularJS 4.1.2 的 platform对象是否是关键因子？

验证方法：
- 删除 app.component.ts 文件里与platform对象相关的代码

  platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do any higher level native things you might need.
      statusBar.styleDefault();
      splashScreen.hide();
    });

验证效果：
- deviceready消息正常。
- 日志如下：

06-17 17:22:54.527 7893-7893/io.ionic.starter D/JsMessageQueue: Set native->JS mode to EvalBridgeMode
06-17 17:22:58.716 7893-7893/io.ionic.starter D/SystemWebChromeClient: file:///android_asset/www/build/main.js: Line 3303 : Angular is running in the development mode. Call enableProdMode() to enable the production mode.

06-17 17:22:58.937 7893-8166/io.ionic.starter I/App: WARNING: Back Button Default Behavior will be overridden.  The backbutton event will be fired!

结论
- AngularJS 4.1.2版本对platform的封装影响了cordova桥js的加载机制。（具体原因需要进一步研究AngularJS源码）。

4 修改问题

修改方法：
- 由于JS的业务逻辑需要在deviceready成功之后才能调用，所以需要手动封装deviceready消息；
- 封装代码如下：

declare const window: any;

export class MyApp {
  rootPage:any = TabsPage;
  constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen) {
      if(window.cordova) {
        document.addEventListener("deviceready", function() {
          // retrieve the DOM element that had the ng-app attribute
          splashScreen.hide();
          // 编写项目业务代码开始

        }, false);
      } else {
        console.log('web 模式');
        // 编写项目业务代码开始
      }
    // platform.ready().then(() => {
    //   // Okay, so the platform is ready and our plugins are available.
    //   // Here you can do any higher level native things you might need.
    //   statusBar.styleDefault();
    //   splashScreen.hide();
    // });
  }
}

测试结果：
- deviceready大约需要3秒准备完成。android应用启动大约1秒，所以整个应用启动到显示出来页面大约为3-4秒。
