Android- How to save Firebase Uid onto SharedPreferences?

After having the user log in and getting their uid, how would I save their uid onto SharedPreferences so I can access it throughout my project? This is my code to get their uid:

FirebaseAuth auth = FirebaseAuth.getInstance();
FirebaseAuth.AuthStateListener authListener = new FirebaseAuth.AuthStateListener() {
    @Override
    public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
        FirebaseUser firebaseUser = firebaseAuth.getCurrentUser();
        if (firebaseUser != null) {
            String userId = firebaseUser.getUid();
            String userEmail = firebaseUser.getEmail();
        } 
    }
};

use this code to save your UID into sharedpreference.

// for saving uid for shared preference



FirebaseAuth auth = FirebaseAuth.getInstance();
FirebaseAuth.AuthStateListener authListener = new FirebaseAuth.AuthStateListener() {
    @Override
    public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
        FirebaseUser firebaseUser = firebaseAuth.getCurrentUser();
        if (firebaseUser != null) {
            String userId = firebaseUser.getUid();
            String userEmail = firebaseUser.getEmail();
            SharedPreferences sp = getSharedPreferences(PREFS_UID ,Context.MODE_PRIVATE);
            sp.edit().putInt(Save_UID,userId ).commit();
        } 
    }
};


// Retrieving id to any activity by calling this

SharedPreferences sp = getSharedPreferences(PREFS_UID,Context.MODE_PRIVATE);
int sc  = sp.getInt(Save_UID,0);

Try like this:

private SharedPreferences sharedPref;
FirebaseAuth auth = FirebaseAuth.getInstance();
FirebaseAuth.AuthStateListener authListener = new FirebaseAuth.AuthStateListener() {
    @Override
    public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
        FirebaseUser firebaseUser = firebaseAuth.getCurrentUser();
        if (firebaseUser != null) {
            String userId = firebaseUser.getUid();
            String userEmail = firebaseUser.getEmail();
            sharedPref = getPreferences(MODE_PRIVATE);
            SharedPreferences.Editor editor = sharedPref.edit();
            editor.putString("firebasekey", userId);
            editor.commit();
        } 
    }
};

To retrieve in other activity: 

        sharedPref = getPreferences(MODE_PRIVATE);
        String UserId = sharedPref.getString("firebasekey", "");
