React-native-fast-image: Crash on Android if source is an invalid URL

[raynor85]

If I pass as source an object like this { uri: 'INVALID_URL' } I get the following error on Android:

Error while updating property 'source' of a view managed by: FastImageView

null

Must not be null or empty

At the moment I am normalising the source using this (ugly) code to avoid the crash:

const normalisedSource = source && typeof source.uri === 'string' && !source.uri.split('https://')[1] ? null : source;

but I think it would be better if the library prevents it.

not all image start https, http ??
const normalisedSource = source && typeof source.uri === 'string' && !source.uri.split('http')[1] ? null : source;

@OrangeFlavoredColdCoffee Your answer works perfectly. Thank you very much! you saved me so much time ^^

[tianliuj]

so I need adjust every source ? It's so Unfriendly！！！

[creative-dev-lab]

const normalisedSource = source && typeof source.uri === 'string' && !source.uri.split('http')[1] ? null : source;

You saved my day!

not all image start https, http ??
const normalisedSource = source && typeof source.uri === 'string' && !source.uri.split('http')[1] ? null : source;

not all images start with https or http. what about local images

[alexdieudonne]

how i could use this function or variable ?

i don't know where

You don’t have to use it necessarily, but it prevents malformed url to
crash on Android devices. If you want to use it, just wrap your fast image
with your own custom component wrapper and apply the function to fast image
data source prop

Thanks you, my problem is solved using this

[thanhdevapp]

Handler local image

class ProgressiveImage extends React.Component {

getUriImage(uri) {
    return uri !== null && uri !== undefined && uri.includes("/") && uri.includes(".") ? uri : ""
}

render() {
    let source = this.props.source;
    return (
        <View style={styles.container}>
            {this.props.source && this.props.source.uri ? <FastImage {...this.props} source={{
                uri: this.getUriImage(this.props.source.uri),
                cache: FastImage.cacheControl.immutable,
            }} /> : <Image {...this.props} />}
        </View>
    )
}

}

I think the library itself should take of this issue, on ios it works perfectly.
