error: method does not override or implement a method from a supertype

Hi

I've been trying to install crosswalk all day without any luck.
When compiling I get two errors:

For public void startActivityForResult(Intent intent, int requestCode, Bundle options) in XWalkCordovaView.java:
error: method does not override or implement a method from a supertype

For public String[] getKeyTypes() in XWalkCordovaClientCertRequest.java:
error: cannot find symbol method getKeyTypes()

I have tried almost all cordova-android versions between 6.0.0 and 7.0.0, I have also tried different Cordova CLI versions, and different versions of this plugin. Nothing helps.

My current setup:
cli packages: (/Users/jonaswestalro/.nvm/versions/node/v6.11.4/lib/node_modules)

@ionic/cli-utils  : 1.19.1
ionic (Ionic CLI) : 3.19.1

global packages:

cordova (Cordova CLI) : 8.0.0 

local packages:

Cordova Platforms : android 6.2.3
Ionic Framework   : ionic1 1.3.1

System:

Android SDK Tools : 26.1.1
