Ionic-framework: ionic2's white screen can be solved?

[alanhg]

Ionic version:

    "@angular/common": "4.0.0",
    "@angular/compiler": "4.0.0",
    "@angular/compiler-cli": "4.0.0",
    "@angular/core": "4.0.0",
    "@angular/forms": "4.0.0",
    "@angular/http": "4.0.0",
    "@angular/platform-browser": "4.0.0",
    "@angular/platform-browser-dynamic": "4.0.0",
    "@angular/platform-server": "4.0.0",
    "@ionic/storage": "2.0.1",
    "ionic-angular": "2.3.0",
    "ionic-native": "2.9.0",
    "@ionic/app-scripts": "^1.2.0",

My Phone
MeiZu Note5 (Android6.0)
Current behavior:

Ionic2 has a very obvious problem is that the app has a long time whiteScreen, this is compared with the ionic1, or very obvious, hoping to improve. of course,ionic2 has a better performance than ionic1 on view change。

The use of AOT compiled after the package is indeed better than JIT, but still whiteScreen is obvious.

# AOT compile
ionic run android --prod 

# config.xml
<preference name="SplashMaintainAspectRatio" value="true"/>
 <preference name="FadeSplashScreenDuration" value="300"/>
 <preference name="SplashScreen" value="screen"/>
 <preference name="SplashScreenDelay" value="3000"/>

Expected behavior:

Start the black and white problem can be solved

Other information:
I noticed that the dependence of ionic2 has been released with ng2, also updated to ng4, and my app has also been upgraded to 4, I now test the white screen did not have the slightest relief.

Well, that just mean you are not handling splash correctly, imo.
I recommend you do:
<preference name="AutoHideSplashScreen" value="false"/>
And remove:
<preference name="SplashScreenDelay" value="3000"/>

Then in your app (assuming you are using ionic native 3+), with no angular context, do:
new SplashScreen().show();
(With no angular context - outside of any class, just import splash and run this)

Then, on platform ready (and after normally injecting splash screen), do:
this.splashScreen.hide();

That means that as long as platform is not ready, you will see a splash-screen. - no white screen

I am using ionic-native 2.9.0
npm view ionic-native and you can know that 2.9.0 is the latest version

@AmitMY it's not a good idea.

[AmitMY]

@heqiang421 For 2.9.0 you just need SplashScreen.show() which is simpler.
Why is that not a good idea?

[alanhg]

@AmitMY Because i think white-screen is obvious due to ionic2'problem.
Your method can't solve this problem,just hide it.
thank you.

[darthdie]

1.2.1 is the latest app-script version, and 3.2.4 is the latest ionic-native verison.
