console.warn('start fail', error);
                this.setState({supported: false});
            })

        if (Platform.OS === 'android') {

                    console.log(err);
                })
            NfcManager.onStateChanged(

            .then(() => NfcManager.isEnabled())
            .then(enabled => this.setState({enabled}))

      .then(() => NfcManager.isEnabled())
