React Native camera works first time then not working (black screen) in android device

I was using an older version of react-native-camera and it worked fine on iOS. But it did not work on Android. I am creating a function like scanning code combines with taking pictures after isBarcodeRead logic done. Then I tried upgrading this lib up to and met the same problem as yours.

I had this issue with react-navigation router. Camera stops working after I changing page This code solved it for me

import { withNavigationFocus } from 'react-navigation' 
    render() {
        const { isFocused } = this.props
        return (
           <View>
             { isFocused && <RNCamera  ... />  }
           </View
         )
    }
    export default withNavigationFocus(Camera) `
