Ionic 4 App doesn't work properly on Android 9.X.X (V4)

Ionic Framework
1

Hi,

I have de following config in my ionic project

Ionic:

   ionic (Ionic CLI)             : 4.12.0 (C:\Users\Dani\AppData\Roaming\npm\node_modules\ionic)
   Ionic Framework               : @ionic/angular 4.2.0
   @angular-devkit/build-angular : 0.13.8
   @angular-devkit/schematics    : 7.2.4
   @angular/cli                  : 7.3.8
   @ionic/angular-toolkit        : 1.4.1

Cordova:

   cordova (Cordova CLI) : 9.0.0
   Cordova Platforms     : android 8.0.0, browser 6.0.0, ios 5.0.0
   Cordova Plugins       : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 3.1.2, (and 10 other plugins)

System:

   Android SDK Tools : 26.1.1 (C:\Users\Dani\AppData\Local\Android\sdk)
   NodeJS            : v10.15.0 (C:\Program Files\nodejs\node.exe)
   npm               : 6.4.1
   OS                : Windows 10

The app is not chrasing but for example I can’t use the gps. So i see that “Cordova Platforms : android 8.0.0” is pointing to 8.0. I was wondering how to update the platform to android 9.0.0.
