I use native plugin import { EmailComposer } from '@ionic-native/email-composer'; constructor(private emailComposer: EmailComposer) { } ... this.emailComposer.isAvailable().then((available: boolean) =>{ if(available) { //Now we know we can send } }); But "available" is undefined now… Befor…

Email Composer : isAvailable -> undefined
