世博指纹无法在许多android模型中使用？

Question

当我从旧的三星或许多其他MeiZu设备访问指纹时出现问题，因此有任何api或其他东西使我可以在旧设备中访问指纹扫描仪吗？ 世博会是否支持对Samsung和MeiZu api进行指纹扫描？或以其他方式在我的应用程序中包含此api？ 谢谢。

有如下代码段

class AndroidScanner extends Component {
    /**
     * For showing scanner initially.
     * @param props
     */
    constructor(props) {
        super(props);
        this.state = {
            showScanner: true,
        };
    }

    /**
     * For toggeling scanner.
     * @private
     */
    _toggleScanner() {
        this.setState({showScanner: false});
    }

    componentDidMount() {
        Expo.Fingerprint.hasHardwareAsync().then(response => {
            hardware = response;
        });
        Expo.Fingerprint.isEnrolledAsync().then(response => {
            enrolled = response;
        });
    }

    authFunction = () => {
        if (!hardware || !enrolled) {
            let message = !hardware ? 'This device doesn\'t support fingerprint scanning.' : !enrolled ? 'No fingerprints registered.' : 'App has no permission.'
            Toast.show(message, Toast.SHORT);
            return;
        }

        if (this.state.showScanner === true) {
            this._toggleScanner();
            try {
                Expo.Fingerprint.authenticateAsync().then(response => {
                    if (response.success) {
                        Toast.show("Auth successful!", Toast.SHORT);
                        this.props.onPreferences(userPreferences);
                        this.props.onLogin(decryptText(getAuthKey));
                    }
                    else if (response.error === 'app_cancel') {
                        return null;
                    } else {
                        this._toggleScanner();
                        Toast.show("Authentication Failure. Please Try Again!", Toast.SHORT);
                        Alert.alert("Authentication Failure", "Please authenticate to login.", [{
                            text: 'Ok',
                            onPress: () => {
                                this.props._toggleAndroidScanner()
                            }
                        }], {cancelable: false});
                    }
                });
            } catch (error) {
                //if Finger scan will fail.
            }
        }
    };

    render() {
        {
            setTimeout(this.authFunction, 1000)
        }
        return (
            <View>
                <View style={androidScannerStyles.outerView}>
                    <Image source={require('../../assets/finger_print.png')}/>
                    <Text style={androidScannerStyles.fingerPrintStyle}>Place Your Finger</Text>
                </View>
            </View>
        );
    }
}
