react-native-receive-sharing-intent

A React Native plugin that enables React Native apps to receive sharing photos, videos, text, urls or any other file types from another app.

Also, supports iOS Share extension and launching the host app automatically. Check the provided example for more info.

Demo

Android Ios

Installation

Npm

$ npm install react-native-receive-sharing-intent --save

Yarn

$ yarn add react-native-receive-sharing-intent

ios

$ cd ios && pod install

Mostly automatic installation less than React Native 0.60.0

$ react-native link react-native-receive-sharing-intent

Note: Ios and Android on Debbuging time not working at sometimes while App is Closed

Create App Group

  • Go to the Capabilities tab and switch on the App Groups switch for both targets. Add a new group and name it group.YOUR_HOST_APP_BUNDLE_IDENTIFIER in my case group.com.ajith.example

  • App group name must be start with group.

  1. Create a app group for main App

group text

  1. Create a app group for Share Extension

group text

Compiling issues and their fixes

  • Error: App does not build after adding Share Extension?

    Fix: Check Build Settings of your share extension and remove everything that tries to import Cocoapods from your main project. i.e. remove everything under Linking/Other Linker Flags

  • You might need to disable bitcode for the extension target

Usage

import ReceiveSharingIntent from 'react-native-receive-sharing-intent';


    // To get All Recived Urls
    ReceiveSharingIntent.getReceivedFiles(files => {
      // files returns as JSON Array example
      //[{ filePath: null, text: null, weblink: null, mimeType: null, contentUri: null, fileName: null, extension: null }]
    },
    (error) =>{
      console.log(error);
    });


    // To clear Intents
    ReceiveSharingIntent.clearReceivedFiles();
