To save data received on onMessgeReceived() to SQLite database even when your app is in the background (no activity running), you can do the following:

1) Create a class that extends IntentService, e.g:

public class SQLService extends IntentService {
    private final static String MESSAGE_ID = "message_id";

    private MySQLiteDbAdapter mySQLiteAdapter;

    public SQLService() {
        super("test-service");
    }

    @Override
    public void onCreate() {
        super.onCreate();

        // initialize SQLite adapter here using getApplicationContext()
        this.mySQLiteAdapter = new MySQLiteDbAdapter(getApplicationContext());

    }

    @Override
    protected void onHandleIntent(Intent intent) {

        // fetch data to save from intent
        Message message = new Message();
        Message.setMessage_id(intent.getStringExtra(MESSAGE_ID));
        ...
        // save 
        this.mySQLiteAdapter.add(message);

    }
}

2) Launch the service class from onMessageReceived() method or a method within your extension of the Firebase service, e.g.:

@Override
    public void onMessageReceived(RemoteMessage remoteMessage) {

        if (remoteMessage.getData() != null) {

            Intent intent = new Intent(this, SQLService.class);
            // add data to intent
            intent.putExtra(MESSAGE_ID, remoteMessage.getData().get(MESSAGE_ID));
            ...
            // start the service
            startService(intent);

        }
    }

3) Register the service in your AndroidManifest.xml:
