If you are using android platform version 10.0.0 or higher. Then you have to remove whitelist plugin, if it is installed in your project. It doesn't work with android 10 or later. This is the reason it shows white screen after opening installed application.

cordova plugin rm cordova-plugin-whitelist
cordova prepare   OR ionic cordova prepare

if prepare doesn't work try to remove platform and add again.

ionic cordova platform rm android
ionic cordova platform add android

Thanks, Hope it helps you.
