I am trying to get one document in my collection with android Firebase Cloud Firestore using clause WhereEqualTo on a one field, but i don't know why i get sometime empty result whith the same data in my database.
Sometime the result is empty. When i remove the clause whereEqualTo, i get all the collection.
here is my request
public static Task<QuerySnapshot> getUserByEmail() {
String email = "mireille@sombux.com";
return UserHelper.getUsersCollection()
.whereEqualTo("email", email)
.get();
}here is my User class
public abstract class User {
private long id;
private String email;
private Date lastLogin;
private Date birthday;
private String country;
private String codcountry;
private String formation;
private String drink;
private String about;
public User() {}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Date getLastLogin() {
return lastLogin;
}
public void setLastLogin(Date lastLogin) {
this.lastLogin = lastLogin;
}
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public String getCodcountry() {
return codcountry;
}
public void setCodcountry(String codcountry) {
this.codcountry = codcountry;
}
public String getFormation() {
return formation;
}
public void setFormation(String formation) {
this.formation = formation;
}
public String getDrink() {
return drink;
}
public void setDrink(String drink) {
this.drink = drink;
}
public String getAbout() {
