You first need to add the platforms that you want to build for. Run
cordova platform add android ios osx windows
to initialize directories in the 'platforms' directory. If you don't want to build the files for some of those platforms, just leave it out of that command.
Next, run
cordova build
to build the app for the instantiated platforms.
cordova platform remove android
cordova platform add android
cordova build android --release --buildConfig
