Another way - try this code in your onCreate:

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if (user != null) {
    // User is signed in
    Intent i = new Intent(LoginActivity.this, MainActivity.class);
    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
    startActivity(i);
} else {
    // User is signed out
    Log.d(TAG, "onAuthStateChanged:signed_out");
}

This will keep the user logged in by taking the user to the Main activity directly without stopping at registration activity. so the user will be logged in unless the user click on signout.
