Если вы не хотите использовать FireBase,
const infoRequest = new GraphRequest(
'/me?fields=name,email,picture.type(large)',
null,
this._responseInfoCallback
);
new GraphRequestManager().addRequest(infoRequest).start();
_responseInfoCallback = (error, result) => {
if (error) {
alert('Error fetching data: ' + error.toString());
} else {
this.setState({ userName: result.name, userEmail: result.email ,userPic:result.picture.data.url});
AsyncStorage.setItem("UserName",this.state.userName);
AsyncStorage.setItem("Email", this.state.userEmail);
AsyncStorage.setItem("UserPic", this.state.userPic);
// SharedPreferences.setItem("UserName", this.state.userName);
// SharedPreferences.setItem("Email", this.state.userEmail);
// SharedPreferences.setItem("UserPic", this.state.userPic);
console.log("Picture"+ this.state.userPic + "Name" + this.state.userName + "Email" + this.state.userEmail);
}
}
