const everRunningJobKey = "everRunningJobKey";

BackgroundJob.register({
  jobKey: regularJobKey,
  job: () => console.log(`Background Job fired!. Key = ${regularJobKey}`)
});
BackgroundJob.register({
  jobKey: exactJobKey,
  job: () => {
    console.log(`${new Date()}Exact Job fired!. Key = ${exactJobKey}`);
  }
});
BackgroundJob.register({
  jobKey: everRunningJobKey,
  job: () => console.log(`Ever Running Job fired! Key=${everRunningJobKey}`)
});

export default class App extends Component {
  constructor(props) {
    super(props);
    this.state = { jobs: [] };
  }

  render() {
    return (

const styles = StyleSheet.create({

  welcome: { fontSize: 20, textAlign: "center", margin: 10 },
  instructions: { textAlign: "center", color: "#333333", marginBottom: 5 }
});

AppRegistry.registerComponent("backgroundjob", () => App);
