import {
  AppRegistry,
  Text,

} from 'react-native';

import BackgroundJob from 'react-native-background-job';
import SmsListener from 'react-native-android-sms-listener';

/*
Register background job with jobKey
*/
const myJobKey = 'Hej';

BackgroundJob.register({
  jobKey: myJobKey,
  job: () => console.log('Background Job fired!')
});

export default class ListenMessageApp extends Component {

  //constructor include last message
  constructor(props) {
    super(props);
    this.state = { lastMessage: 1 };
  } …
