react-native-share: Unable to share local file on Android

I added <uses-permission tools:node="remove" android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> In manifestFile. After removing it, share is working fine for me.

I managed to solve this issue by passing the pdf file path to the url param from sharing options. sharePDf = async (pdfPath) => { //Be sure that PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE is already granted const shareOptions = {

    url: 'file://'+pdfPath,
    mimeType: 'application/pdf',
    title: 'Pdf test'
    };

Platform.OS === ‘ios’ ?
Share.open(shareOptions) : this.sharePDFWithAndroid(pdfPath, ‘application/pdf’); }

My share function for android is :

sharePDFWithAndroid(pdfPath, type) { const { fs, fetch, wrap } = RNFetchBlob; RNFetchBlob.fs.readFile(pdfPath, ‘base64’).then( base64Data => { base64Data = data:${type};base64, + base64Data; Share.open({ url: base64Data }); }); }

After a lot of research, I found out that only base64 data for pdf file can be shared using react-native-share. Is not possible to share using url with “file://…pdfPath…”.

I hope that someone will find this helpfull.

After few days stuck in this problem, I figured out that files in cache folder are able to be shared without any problem. But I still waiting a solution to share files from ‘files’ folder.

@ramonscampos please let me know what file types you need to share? I can try to share it as well.

hello。I tried to share the.xls file, but it didn’t work。

import { writeFile, readFile, unlink, DocumentDirectoryPath, ExternalDirectoryPath, } from ‘react-native-fs’

writeFile(file, output(wbout), ‘base64’) .then(res => { console.log(file) this.readFile(filePath) // resolve(file) })

readFile(filePath, “base64”).then((res)=>{ console.log(res) const dataUri = data:excel/xls;base64,${res}; Share.open({ url: dataUri, }); I finally solved the problem of android sharing excel files.Here is the full code。

import XLSX from 'xlsx'
import {
    writeFile,
    readFile,
    unlink,
    DocumentDirectoryPath,
    ExternalDirectoryPath,
} from 'react-native-fs'
import { Platform } from 'react-native'
import { Toast } from '@ant-design/react-native'
import Share from 'react-native-share';


/**

const exportExcel = (data: Array, fileName: string) => {
    let ipt = new Promise(function(resolve, reject) {
        try {
            const output = str => str
            const path = Platform.select({
                ios: `${DocumentDirectoryPath}/`,
                android: `${ExternalDirectoryPath}/`
            })
            const fileType = 'xls'
            if (data && data.length > 0) {
                let ws = XLSX.utils.aoa_to_sheet(data)
                let wb = XLSX.utils.book_new()
                XLSX.utils.book_append_sheet(wb, ws, fileName)
                const wbout = XLSX.write(wb, {
                    type: 'base64',
                    bookType: fileType
                })
                const file = `${path}${fileName}.${fileType}`
                writeFile(file, output(wbout), 'base64')
                    .then(res => {
                        console.log(file)
                        wxShareFile(fileName, file, resolve, reject)

            } else {
                alert('没有可分享的数据')
            }
        } catch (e) {
            console.log(e)
            reject(e)

         Share.open({
            url: dataUri,
        });
         // unlink(path);

    })

}
