Android local file share doesn't share contents of file

Steps to reproduce

1. Attempt to share a local text file via Share.open using the local path as described in the docs, e.g. url: "file:///storage/emulated/0/test.txt"

Expected behaviour

The contents of the file should be shared to the selected app

Actual behaviour

Instead of the file contents the file url is shared to the app, e.g. if I share to Gmail the string “file:///storage/emulated/0/test.txt” is copied into the email.

Environment

• React Native version: .55.3
• React Native platform + platform version: Android 8.1.0

react-native-share

Version: 1.1.2

@watchtower314 add below code add app/src/main/AndroidManifest.xml

        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:grantUriPermissions="true"
            android:exported="false">
            <meta-data
                tools:replace="android:resource"
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/filepaths" />
        </provider>

and in res/xml/filepaths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="myexternalimages" path="Download/" />
    <root-path name="root" path="" />
    <files-path
        name="files-path"
        path="." /> <!-- Used to access into application data files -->
</paths>

and path add prefix file://,so result path :file:///data/user/0/com.appName/cache/123456.pdf, it will work fine

@suwu150 's solution did the trick! Although at first it seemed not to work; it caused a different error that said failed to find configured root that contains /file:/storage/emulated/0/123456.pdf but after removing the app from my device and rebuilding, it worked perfectly!

Thanks!!
