Answer 1

Add the plugin (check this link):
cordova plugin add cordova-plugin-googleplus --save --variable REVERSED_CLIENT_ID=myreversedclientid
Include the lib:
import { GooglePlus } from 'ionic-native';
Now the login:
googlePlus_login() {
GooglePlus.login(
{
'scopes': '',
'webClientId': '',
'offline': false
}
).then(
(success) => {
alert( '\n id: ' + JSON.stringify(success.userId) +
'\n name: ' + JSON.stringify(success.displayName) +
'\n email: ' + JSON.stringify(success.email)
);
},
(failure) => {
console.log('GOOGLE+ login FAILED', failure);
}
);
}
where:
scope: optional, space-separated list of scopes, If not included or empty, defaults to profile and email.
webClientId: optional clientId of your Web application from Credentials settings of your project - On Android, this MUST be included to get an idToken. On iOS, it is not required.
offline: optional, but requires the webClientId - if set to true the plugin will also return a serverAuthCode, which can be used to grant offline access to a non-Google server.
Logout function:
googlePlus_logout() {
GooglePlus.logout().then(
(success) => {
console.log('GOOGLE+: logout DONE', success);
},
(failure) => {
console.log('GOOGLE+: logout FAILED', failure);
}
);
}
Hope it will help you. :)
