I am having this issue too :/

Have you solved it yet?

[BDominik]

Same here.
Any solution?

[BDominik]

I already found this solution somewhere else but then it's didn't worked.
Ionic Info

Ionic:

ionic (Ionic CLI) : 4.0.5 (C:\Users\bdomi\AppData\Roaming\npm\node_modules\ionic)
Ionic Framework : ionic-angular 3.9.2
@ionic/app-scripts : 3.1.11

Cordova:

cordova (Cordova CLI) : 8.0.0
Cordova Platforms : not available

System:

Android SDK Tools : 26.1.1
NodeJS : v8.11.3 (C:\Program Files\nodejs\node.exe)
npm : 6.3.0
OS : Windows 10

So now what I did is the folowing.
In the platforms/android/cordova-safe/starter-conceal.gradle change this
compile('com.facebook.conceal:conceal:1.0.0@aar')
to this
compile('com.facebook.conceal:conceal:2.0.1@aar')
I hope it will work for you too.
