White screen after splashscreen, Ionic2, android device

I am currently developing Ionic2 app. I face a problem that after Splash screen, there is a white screen for 6-7 seconds, before app home screen.

I tried some googling but nothing works. My last attempt to solve is

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

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

Please help me in this issue;

EDIT:: My ionic info is

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

Solution

Updating Ionic project and change some preferences did the trick for me.

Here the changelog and infos.

1 - Update to the latest version of the Ionic CLI, Cordova and Typescript:

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

2 - Update your package.json to match the following dependencies, remove existing node_modules directory, and then run 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 - Update your config.xlm with these preferences (live review is ok):

  <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 - Then I have copy/pasted some code that had been modified recently from here into my project (Ionic 2 demo and up to date app - Check the Github).

Now the application starts successfully without long splashscreen.

ps:

livereview: ionic run android -l
production: ionic run android --prod --release
Remember that you have to hide manually the splashscreen (like @Markus Wagner said) in your app.component.ts: this.platform.ready().then(() => { Splashscreen.hide(); });

EDIT: Update to Ionic v3.1.1 (2017-04-28)
