Yess that link has helped me solve the new error by doing this:
For me I was able to fix it by removing the following line from project.properties:
cordova.system.library.12=com.android.support:support-v13:26.+
Before:
cordova.system.library.8=com.android.support:support-v4:24.1.1+
cordova.system.library.12=com.android.support:support-v13:26.+
cordova.system.library.9=com.android.support:support-v4:26.+
After:
cordova.system.library.8=com.android.support:support-v4:24.1.1+
cordova.system.library.9=com.android.support:support-v4:26.+
