FireBase Authentication Auth State Changed

I want to be able to pass an intent to an activity based on if the login state changes for the user i have to following AuthStateListener within the OnCreate method of the LoginAct

Solution 1:

The answer was fairly logical in the end

I moved the Firebase Auth call to my main activity and amended the process to forward an intent to the Login activity rather than the other way round. This avoids any infinite loops

mAuthListener = new FirebaseAuth.AuthStateListener() {
            @Override
            public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                FirebaseUser user = firebaseAuth.getCurrentUser();
                if (user != null) {
                    // User is signed in
                  //  Intent intent = new Intent(getBaseContext(), MainActivity.class);
                    //intent.putExtra("EXTRA_SESSION_ID", sessionId);
                  //  startActivity(intent);
                   // Log.d("LOG_Login", "onAuthStateChanged:signed_in:" + user.getUid());
                } else {
                    // User is signed out
                    String className = this.getClass().getName();
                    if (!(className == "LoginActivity")) {
                         Intent intent = new Intent(getBaseContext(), LoginActivity.class);
                       // intent.putExtra("EXTRA_SESSION_ID", sessionId);
                         startActivity(intent);
                    }

                    Log.d("LOG_Login", "onAuthStateChanged:signed_out");
                }
                // ...
            }
        };

        mAuth.addAuthStateListener(mAuthListener);
