I have a problem that I am creating an online game app in which I ask the user to either host or join a group. The creating of group is working but joining is not working. In joining i want that when a person joins a group with a unique group id i want his name to be added to the database.
@Akshat_Rana , I cont understand, here why do you generate random number for group ID. I modified to display it in text , you can change it into your convenient. Solved your doubts?
