ionic3 启动白屏处理

重点就就三点

1.设置不自动隐藏splashscreen页面，设置最多延迟10s再关闭，这样可以不显示启动前的白画面

 <preference name="AutoHideSplashScreen" value="false" />
    <preference name="FadeSplashScreenDuration" value="" />
    <preference name="ShowSplashScreen" value="true" />
    <preference name="ShowSplashScreenSpinner" value="false" />
    <preference name="SplashShowOnlyFirstTime" value="false" />
    <preference name="FadeSplashScreen" value="true" />
    <preference name="webviewbounce" value="false" />
    <preference name="UIWebViewBounce" value="false" />
    <preference name="DisallowOverscroll" value="true" />
    <preference name="android-minSdkVersion" value="" />
    <preference name="BackupWebStorage" value="none" />
    <preference name="SplashMaintainAspectRatio" value="true" />
    <preference name="SplashScreen" value="screen" />
    <preference name="SplashScreenDelay" value="" />
    <preference name="loadUrlTimeoutValue" value="" />

2.设置不显示载入的圆圈

<preference name="ShowSplashScreenSpinner" value="false" />

3.目录文件src/app 的app.component.ts中有来确保程序启动后关闭splashscreen页面（不用设置）

platform.ready().then(() => {
Splashscreen.hide();
});

1. 4.打包

   ionic build android --prod --release
