Answer 1

In your React-Native app, you can get the token like this:
messaging().getToken().then(token => { saveTokenToDatabase(token);});
then listen for any token change
messaging().onTokenRefresh(token => {saveTokenToDatabase(token);});
The method saveTokenToDatabase is used to save the token to your backend so that you can access it later to send messages

In android you need to use this class to get device token
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onNewToken(String token) {
super.onNewToken(token);
Log.e("newToken", token);
//Add your token in your sharefpreferences.
SharedPreferenceManager app_sp = new SharedPreferenceManager(this);
app_sp.putString(Constants.FIREBASE_TOKEN, token);
this service request which update device token on to your server
// updatetokenAPI.updateToken(token);
