[Ionic 4] Problem building for Android: white screen after splashscreen

Ionic Framework
3

It can be for some reasons:

1- You have to be careful with the splash image, there are a lot of tools that can help you with that!

2- It can be the config.xml (put these below):

<preference name="SplashMaintainAspectRatio" value="true" />
<preference name="FadeSplashScreenDuration" value="300" />
<preference name="FadeSplashScreen" value="true" />
<preference name="AutoHideSplashScreen" value="false" />
<preference name="ShowSplashScreen" value="true" />

3- It can be from URL Timeout Value

Try this (in config.xml) :

<preference name="loadUrlTimeoutValue" value="700000"/>

4 - It can because of the way you´re launching the app:
Try

ionic cordova run android --prod
