base64 image not sharing in react native android - react-native

Question

I am using react-native-share to share something in hangouts, whatsapp and so on... here is my code that i tried,
i imported the
import RNFetchBlob from 'react-native-fetch-blob';
import Share from 'react-native-share';
so used RNFetchblob to convert image url to base64, and added the dependencies based on the api.
_downloadImageAndShare(title, message, url) {
const { fs } = RNFetchBlob.fs;
var self = this;
RNFetchBlob.config({ fileCache: true })
.fetch('GET', url)
.then(resp => {
return resp.readFile('base64')
.then(base64 => {
return { resp, base64 };
})
})
.then(obj => {
console.log(obj)
var headers = obj.resp.respInfo.headers;
var type = headers['Content-Type'];
var dataUrl = 'data:' + type + ';base64,' + obj.base64;
console.log('dataurl is', dataUrl)
return { title, message, url: dataUrl };
})
.then(options => {
return Share.open(options);
console.log('options is', options)
}).catch(err => {err && console.log(err); })
}
<ShareIcon onTrigger={ () => this._downloadImageAndShare('sample', `${title} sample. More http://www.sample.com`, shareImage) } white={!!whiteIcon} />
here I am getting the response image url converted in base64 format. I want to share the a content , link and the image. These procedure working fine in iOS.
But in android image is not getting share.
