白屏后闪屏,Ionic2,android设备

我正在开发Ionic2应用程序.我遇到一个问题,在Splash屏幕之后,有一个白色屏幕6-7秒,在应用程序主屏幕之前.

我尝试了一些谷歌搜索,但没有任何作用.我最后一次尝试解决的是

hideSplashScreen() {
    if(Splashscreen){
      setTimeout(() => {
        Splashscreen.hide();
      },100)
    }
  };//

<preference name="SplashMaintainAspectRatio" value="true"/>
<preference name="FadeSplashScreenDuration" value="300"/>

请帮我解决这个问题

EDIT ::我的离子信息是

Cordova CLI: 6.4.0 
Ionic Framework Version: 2.0.0-rc.4
Ionic CLI Version: 2.1.17
Ionic App Lib Version: 2.1.7
Ionic App Scripts Version: 0.0.47
ios-deploy version: 1.8.6 
OS: OS X El Capitan
Node Version: v6.3.1
Xcode version: Xcode 7.2 Build version 7C68

解决方法

更新Ionic项目并改变一些偏好对我来说是个窍门.

这里changelog and infos.

1 – 更新到最新版本的Ionic CLI,Cordova和Typescript：

npm uninstall -g ionic cordova typescript
npm install -g ionic cordova typescript

2 – 更新您的package.json以匹配以下依赖关系,删除现有的node_modules目录,然后运行npm install：

"scripts": {
    "build": "ionic-app-scripts build","clean": "ionic-app-scripts clean","ionic:build": "ionic-app-scripts build","ionic:serve": "ionic-app-scripts serve"
  },"dependencies": {
    "@angular/common": "4.0.2","@angular/compiler": "4.0.2","@angular/compiler-cli": "4.0.2","@angular/core": "4.0.2","@angular/forms": "4.0.2","@angular/http": "4.0.2","@angular/platform-browser": "4.0.2","@angular/platform-browser-dynamic": "4.0.2","@ionic-native/core": "3.6.1","@ionic-native/in-app-browser": "3.6.1","@ionic-native/splash-screen": "3.6.1","@ionic-native/status-bar": "3.6.1","@ionic/storage": "2.0.1","ionic-angular": "3.1.1","ionicons": "3.0.0","rxjs": "5.1.1","sw-toolBox": "3.4.0","zone.js": "0.8.9"
  },"devDependencies": {
    "@ionic/app-scripts": "1.3.6","typescript": "2.3.2"
  }

3 – 使用这些首选项更新您的config.xlm(实时评论可以)：

<preference name="loadUrlTimeoutValue" value="700000"/>
  <preference name="webviewbounce" value="false"/>
  <preference name="UIWebViewBounce" value="false"/>
  <preference name="disallowOverscroll" value="true"/>
  <preference name="android-minSdkVersion" value="16"/>
  <preference name="BackupWebStorage" value="none"/>
  <preference name="StatusBarStyle" value="default"/>
  <preference name="SplashScreen" value="screen"/>
  <preference name="orientation" value="default"/>
  <preference name="SplashMaintainAspectRatio" value="true"/>
  <preference name="FadeSplashScreenDuration" value="300"/>
  <preference name="ShowSplashScreenSpinner" value="false"/>
  <preference name="AutoHideSplashScreen" value="false"/>
  <preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine"/>
  <preference name="SplashScreenDelay" value="3000"/>

4 – 然后我将一些最近从here修改的代码复制/粘贴到我的项目(Ionic 2演示和最新的应用程序 – 检查Github).

现在应用程序启动成功,不需要长时间的防溅.

PS：

> livereview：ion运行android -l
>生产：离子运行android –prod – 释放
>记住,你必须在你的app.component.ts：this.platform.ready().然后(()=> {Splashscreen.hide();})手动隐藏闪屏(像@Markus Wagner说)

编辑：更新到Ionic v3.1.1(2017-04-28)
