問題描述：

使用 ionic3.4.0 創建的 ionic項目（其中Android框架6.2.3版本、AngularJS框架4.1.2版本、Cordova源碼JS端6.2.3版本）

使用ionic cordova build android生成apk安裝包。

運行apk安裝包啟動頁面動畫等待3秒，之后頁面白屏5秒。共計啟動頁面需要8秒的時間。

結論：程序運行啟動需要8秒，用戶體驗無法接受。

1、可能引發該問題的X因子集合

Cordova橋JS端源碼（AngularJS 3.2.0版本）
Cordova橋android端源碼
cordova-plugin-splashscreen插件源碼

2、使用f方法針對X因子進行測試驗證

2.1 驗證cordova-plugin-splashscreen插件是否是關鍵因子？

驗證方法：
- 使用ionic cordova plugin刪除 cordova-plugin-splashscreen插件，并刪除JS端相關的splashscreen的調用方法，運行應用，查看效果；
驗證效果：
- 啟動動畫頁面消失，白屏5秒進行應用；
結論：
- cordova-plugin-splashscreen對控制啟動頁面動畫。（該3秒的時間可可以通過修改config.xml里的 SplashScreenDelay 來控制時間長短。）

2.2 驗證Cordova橋android端源碼是否是關鍵因子？

因為ionic1中沒有出現此問題，對比了ionic1與ionic3項目中除了AngularJS端的代碼差異。

驗證方法：
- 使用beyond compare軟件對比兩個項目的代碼文件。
驗證效果：
- cordova-plugin-splashscreen、android框架包沒有差異。
結論：
- 80%排除原生端代碼對該問題的影響。

2.3 驗證AngularJS3.2.0是否是關鍵影響因子？

2.3.1 使用ionic2中的AngularJS 1.5.3 版本進行驗證：

驗證方法：
- 互換ionic2與ionic3中platforms/android/assets/www目錄；
驗證效果：

組合方式	ionic版本	AngularJS版本	驗證時間
正常組合	ionic2	1.5.3	3秒
	ionic3	4.1.2	8秒
測試組合	ionic2	4.1.2	8秒
	ionic3	1.5.3	3秒

結論：
- 該問題80%的可能性與AngularJS的版本更換內容有關。

3、尋找具體原因

3.1 查看日志是否包含有效信息？

查看android studio輸出日志如下：

日志關鍵詞語：
- Angular is running in the development mode. Call enableProdMode() to enable the production mode.-->需要設置AngularJS為生產模式。
- deviceready has not fired after 5 seconds.-->cordova的deviceready消息沒有被觸發，5秒超時后cordova框架自動發出消息；

3.1.1 驗證設置AngularJS為生產模式是否是關鍵因子？

驗證方法：
//測試方法：在main.js添加以下代碼：
import {enableProdMode} from '@angular/core';
enableProdMode();
驗證效果：
- 啟動應用仍然需要8秒；
結論：
- AngularJS的生產、開發模式不是關鍵因子。

3.1.2 驗證 deviceready 消息超時是否是關鍵因子？

驗證方法：
- 閱讀 cordova橋JS端源碼，如果deviceready消息超時，會打印出影響超時的模塊內容，但是查看日志，并沒有輸出對應模塊的內容。
- 使用AngularJS 1.5.3 版本測試，查看日志；（詳細日志見附錄5.2）
驗證效果
- AngularJS 1.5.3正常，deviceready消息大約3秒左右完成。
- AngularJS 4.1.2不正常，deviceready消息總是超時（原因不明，可能是ionic-angularjs封裝時導致了 onDOMContentLoaded 存在問題，測試日志見文檔末尾）
結論：
- onDOMContentLoaded 消息存在問題，而AngularJS與onDOMContentLoaded消息有關的模塊只有 AngularJS 封裝的 platform對象；

3.1.3 驗證 AngularJS 4.1.2 的 platform對象是否是關鍵因子？

驗證方法：
- 刪除 app.component.ts 文件里與platform對象相關的代碼

  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();
    });

驗證效果：
- 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!

結論
- AngularJS 4.1.2版本對platform的封裝影響了cordova橋js的加載機制。（具體原因需要進一步研究AngularJS源碼）。

4 修改問題

修改方法：
- 由于JS的業務邏輯需要在deviceready成功之后才能調用，所以需要手動封裝deviceready消息；
- 封裝代碼如下：

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();
          // 編寫項目業務代碼開始

        }, false);
      } else {
        console.log('web 模式');
        // 編寫項目業務代碼開始
      }
    // 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();
    // });
  }
}

測試結果：
- deviceready大約需要3秒準備完成。android應用啟動大約1秒，所以整個應用啟動到顯示出來頁面大約為3-4秒。
