How to upgrade the androidmanifestversion.xml from config.xml

I am invoking a release build of android on my app with

cordova build --release android

but I can’d find clear information on ow to setup my config.xml to bump the versioncode for android.

Thanks in advance for the help.

The second line of your config.xml should have a <widget> tag with the version property. If you modify that version property and build it again then it should update your android version
