After splash screen, display white screen long time


#1

I have created a sidemenu template application with Ionic 2.
When I bootstrap the app, appear a splash screen and display white screen long time.

How can I remove the white screen?


White blank screen
Splash scrren
#2

Sound like this is the (HTML/JS) app loading until it can be viewed.

How did you build your app?
What is your app doing during the white screen is displayed?

Hello @Sujan12

I have created Ionic 2 app based on the angular 2 with sidemenu template.
And I built my app as follows command:

ionic platform add android
ionic run android

The white screen is displayed for 7~9 sec.

I had the same problem. The solution was update to 2.0 version and add the following in app.component.ts:

  constructor(platform: Platform) {
platform.ready().then(() => {
  this.hideSplashScreen();
});
  }
  hideSplashScreen() {
if (Splashscreen) {
  setTimeout(() => {
    Splashscreen.hide();
  }, 100);
 }
}

  1. Same problem on iOS builds?
  2. Tried ionic run android --prod?
  3. Are you running on a local real device or emulator?

#6

Hello @Sujan12
I will try that way.
And I was tested on real device.


#7

If you didn’t use any native plugins, you can also try to ionic upload and then use Ionic View (from the App / Play Store) to display your app - see if the same problem exists there.


#8

Hello @Sujan12
Can you explain how to use Ionic view from the App / Play store?
I am very interesting to use Ionic view.
Thank you.


#9

Only for debugging, but can help you pinpoint the problem:

Hello @sebafra
I have tried to fix my bug with your method.
I already developed my app with Ionic 2.
Unlikely I didn’t fix yet.


#11

Thank you @Sujan12

ionic run android --prod

It’s helpful. I fixed issue with this command.
When I build release version, how can I do?


#12

Just combine the two together:
ionic build android --prod --release


#13

Thank you for your help.
And I have some question.
Can you help me.
I am going to create the app that run background after login from back end service.
How can I do?


#14

You’re welcome.

Please open a new thread and describe a bit more what exactly you are trying to do. Maybe I or someone else will be able to help.

White screen after run android
#17

I’ve solved that issue by setting the correct parameters on config.xml

 <preference name="AutoHideSplashScreen" value="false" />
 <preference name="SplashScreenDelay" value="10000" />
 <preference name="FadeSplashScreenDuration" value="1000" />
 <preference name="SplashScreen" value="screen" />
 <preference name="ShowSplashScreen" value="true" />
 <preference name="ShowSplashScreenSpinner" value="false" />
 <preference name="SplashShowOnlyFirstTime" value="false" />
 <preference name="FadeSplashScreen" value="true" />

Then, on my platform.ready() instruction all I do is Splashscreen.hide();

  <preference name="SplashScreen" value="screen"/>
  <preference name="AutoHideSplashScreen" value="false" />  
  <preference name="ShowSplashScreen" value="true"/>
  <preference name="SplashScreenDelay" value="30000"/>
