[REQUIRED] Step 2: Describe your environment

• Android Studio version: 4.1 RC
• Firebase Component: Realtime Database, Appcheck, FirebaseAuth
• Component version: com.google.firebase:firebase-database:20.0.0, com.google.firebase:firebase-appcheck-safetynet:16.0.0-beta02,com.google.firebase:firebase-auth-ktx:21.0.1

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

After user is authenticated with FirebaseAuth, It cannot load data from real-time database. When I closed the application and reopened it, it worked normally, data were displayed.

Relevant Code:

initialize firebase sdk and appcheck

       super.onCreate();
        FirebaseApp.initializeApp(this);
        FirebaseDatabase.getInstance().setPersistenceEnabled(true);
        FirebaseAppCheck firebaseAppCheck = FirebaseAppCheck.getInstance();
        firebaseAppCheck.installAppCheckProviderFactory(
                SafetyNetAppCheckProviderFactory.getInstance());
        firebaseAppCheck.setTokenAutoRefreshEnabled(true);

and I tried to load data by this code

 private val collectionEventListener = object : ValueEventListener {
        override fun onCancelled(error: DatabaseError) {
                Log.e("data","error")
        }

        override fun onDataChange(snapshot: DataSnapshot) {
              Log.d("data","loaded")
      }
}

 FirebaseAuth.getInstance().addIdTokenListener(FirebaseAuth.IdTokenListener {
            val user = it.currentUser
            if(user!=null){
                FirebaseDatabase.getInstance().reference.child("tasks").child(user.uid).addValueEventListener(object:
                ValueEventListener {
                override fun onDataChange(snapshot: DataSnapshot) {
                    Log.e("data","onDataChange")
                }

                override fun onCancelled(error: DatabaseError) {
                    Log.e("data","onCancelled")
                }
            })
            }
        })
     

It didn’t even run into the onDataChange or onCancelled callback and didn’t log anything.
