Firebase Permission denied Error

Question

I am Very beginner to firebase and trying to get value from my database.

but it showing me same error every time.

    W/SyncTree: Listen at /child fa         


        

Answer 1

Listen at /child failed: FirebaseError: Permission denied

It means that the node "child" does not have access permission.

For a more secure approach, define the rule as follows:

{

 "rules": { 

"child": {

    ".read": "auth != null && auth.uid !=null" ,

    ".write": "auth != null && auth.uid !=null"  
   }

}
