During the chat, the 'Send' & Emoticon button is not pressed.
The app stops when you load a photo from the gallery. However It is well stored in the Firebase repository.
Error :
NullPointerException: Attempt to invoke virtual method com.google.firebase.database.DatabaseReference com.google.firebase.database.DatabaseReference.child(java.lang.String)' on a null object reference
I really enjoyed it. But there are some problems.

I want to know what rules Firebase used. 👍 👍 👍
