I have searched through all the QBUser tutorials, but cannot find the way to delete the user tags. Anyone knows how to do it from the application and without deleting the user and recreating it?
Use the 'Edit user' API
http://quickblox.com/developers/SimpleSample-users-android#Update_own_profile
QBUser user = new QBUser();
user.setId(53779);
StringifyArrayList<String> tags = new StringifyArrayList();
tags.add("man");
user.setTags(tags);
QBUsers.updateUser(user, new QBEntityCallback<QBUser>(){
@Override
public void onSuccess(QBUser user, Bundle args) {
}
@Override
public void onError(QBResponseException errors) {
}
});
