I developed an ionic3 app that uses phonegap-push-plugin in order to recive push-notifications.
Does anyone knows how many time do I have to call “registration” like this
pushObject.on('registration').subscribe((registration: any) => console.log('Device registered', registration));
a) Do I have to make a “registration” every time I open my app?
b) Or is enought only once after first installing the app?
… and why ?
