androidNavigationBar Hide Not working

I’m using expo and reat-nactive-webview

androidNavigationBar sticky-immersive Mode when application runs for the first time, it works normally
However operation does not work after entering the keypad. Where should I look?

"androidNavigationBar": {
            "visible": "sticky-immersive"
//my app code
import * as React from 'react';
import { View } from 'react-native';
import { WebView } from 'react-native-webview';

export default class App extends React.Component {
    render() {
        return (
            <View style={{ flex: 1 }}>
                        uri: '',

resolved this problem , it’s expo-cli issue
