To solve that :

you_app_folder/plugin and look for plugin.xml in all the plugins

Go to your plugin folder, search in that directory for :

com.android.support:support-v4:+

OR

com.android.support:support-v4:24.1.1+

OR

com.android.support:appcompat-v7:28.0.0

Change it with :

com.android.support:support-v4:27.1.0

OR

com.android.support:appcompat-v7:27.1.1

then

Also, I executed

ionic cordova platform remove android

and

ionic cordova platform add android

I had the same problem and changing from com.android.support:support-v4:+ to compile com.android.support:support-v4:23.+ fixed it for me.

I fixed it by editing platforms/android/build.gradle according to github.com/crosswalk-project/cordova-plugin-crosswalk-webview/…

@nanusdad this is an option to change only the module you want to upgrade, not all of them
