Using Cincopa in React Native WebView

If you are building React Native application and want to embed your Cincopa video or gallery with webview you can use React Native WebView.
React Native WebView is a modern, well-supported, and cross-platform WebView for React Native. It is intended to be a replacement for the built-in WebView (which will be removed from core).

Here is a small example of how to embed cincopa.com homepage in your React Native application with WebView. Note that the video is running perfectly inside the WebView.

import React from 'react';
import { WebView } from 'react-native-webview'

const App = () => {
  return (
    <>
      <WebView
        mediaPlaybackRequiresUserAction={false}
        allowsInlineMediaPlayback={true}
        allowsFullscreenVideo={true}
        source={{ uri: "https://cincopa.com" }}
      />
    </>
  );
};

export default App;

​You can check full API reference here – https://github.com/react-native-webview/react-native-webview/blob/master/docs/Reference.md.

Here is explained props that we’ve used in the example

  • mediaPlaybackRequiresUserAction
    Boolean that determines whether HTML5 audio and video require the user to tap them before they start playing. The default value is true. (Android API minimum version 17).​
    NOTE: the default true value might cause some videos to hang loading on iOS. Setting it to false could fix this issue.
  • allowsInlineMediaPlayback
    Boolean that determines whether HTML5 videos play inline or use the native full-screen controller. The default value is false.​
    NOTE: In order for the video to play inline, not only does this property need to be set to true, but the video element in the HTML document must also include the webkit-playsinline attribute.
  • allowsFullscreenVideo
    Boolean that determines whether videos are allowed to be played full-screen. The default value is false.​​
    Cincopa Runtime API already providing events that can be used to detect when the video goes to fullscreen or exit from fullscreen and it can be used to handle and post a message to your ReactNative application ( more examples of Cincopa Runtime API usage you can find here – https://www.cincopa.com/media-platform/api-runtime-documentation )

cincopa = cincopa || {};
cincopa.registeredFunctions = cincopa.registeredFunctions || [];
cincopa.registeredFunctions.push({
    func: function (name,data,gallery) {

        // your code here, for ex call window.ReactNativeWebView.postMessage

    },
    filter: "video.fullscreenenter"
});

cincopa.registeredFunctions.push({
    func: function (name,data,gallery) {

          // your code here, for ex call window.ReactNativeWebView.postMessage

    },
    filter: "video.fullscreenexit"
});


React Native WebView providing API to invoke onMessage from webview and it can be used for example to rotate the screen when the video goes to fullscreen mode.

onMessage
A function that is invoked when the webview calls window.ReactNativeWebView.postMessage. Setting this property will inject this global into your webview.

window.ReactNativeWebView.postMessage accepts one argument, data, which will be available on the event object, event.nativeEvent.data. data must be a string.

TIP:
Starting with Android 9 (API level 28) http url will not work by default so if you want to load urls with http you have to do changes in your AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        ...
        android:usesCleartextTraffic="true"
        ...>
        ...
    </application>
</manifest>
