Hello please help.I am a beginner. I've tried trying ways to initialize Firebase still bugging me but I can not find it where it can be.AS, 3.2.1 Thank you https://hastebin.com/vaficulena.cs https://hastebin.com/javidimawa.cpp

Hi, check your gradle dependencies (see manual setup in official example - https://firebase.google.com/docs/android/setup)

https://hastebin.com/koqarosivu.php https://hastebin.com/honuqasemi.bash

This is your error

Default FirebaseApp is not initialized

. Move

FirebaseApp.initializeApp(this)

to line

37

ok,thanks

Based on the error log, you haven't initialize the auth variable. Put this on

auth = FirebaseAuth.getInstance();

See https://firebase.google.com/docs/auth/android/start/

Ok, thanks
