White blank screen appears after splash scrren

After testing the app in android , after displaying the splash screen a white blank screen appears for around 2 sec . How to remove this white screen ???

How are you building your app?
Are you using --prod to create an optimized build?

Also post your ionic info output please.

No i used --debug

Abd this is my ionic info

 @ionic/cli-utils  : 1.9.2
    ionic (Ionic CLI) : 3.9.2

global packages:

    Cordova CLI : 7.0.1

local packages:

    @ionic/app-scripts : 2.1.4
    Cordova Platforms  : android 6.2.3
    Ionic Framework    : ionic-angular 3.6.1


    Android SDK Tools : 25.2.3
    Node              : v6.11.2
    npm               : 3.10.10
    OS                : Windows 8

Building with the --prod flag will improve the performance of the app, and in my experience normally removes that 2 second white screen.

this --prod command is showing error

Error: Type FirstPage in C:/ionic/project/src/pages/first/first.ts is part of the declarations of 2 modules: AppModule in C:/
ionic/project/src/app/app.module.ts and FirstPageModule in C:/ionic/project/src/pages/first/first.module.ts! Please cons
ider moving FirstPage in C:/ionic/project/src/pages/first/first.ts to a higher module that imports AppModule in C:/ionic/project/src/app/app.module.ts and FirstPageModule in C:/ionic/project/src/pages/first/first.module.ts. You can also create a
 new NgModule that exports and includes FirstPage in C:/ionic/project/src/pages/first/first.ts then import that NgModule in A
ppModule in C:/ionic/project/src/app/app.module.ts and FirstPageModule in C:/ionic/project/src/pages/first/first.module.

Are you using lazy loading?

If so, go ahead and remove FirstPageModule from your app.module.ts file.

Otherwise, go head and remove the first.module.ts file.

If i remove… will that make any issue… i cant risk it. now or in future

It will only be an “issue” if you decide to do lazy loading later on. However if you look at the file you can see that it’s pretty easy to recreate.

ok i will try this… thanks man

If you’re using the CLI to generate pages (i.e. via ionic g page) going forward you can pass the --no-module flag to have it, well, not create a module file.
E.g. ionic generate page Detail --no-module
