Sept 27, 2019

Introduction:

This wiki page explains the design changes to integrate content-player in mobile(with ionic 4 changes)

Issue ID:- https://project-sunbird.atlassian.net/browse/SB-14688

Background: 

Mobile code is updating the code to Ionic 4. With this update, file system can't accessible directly while playing the content in content-player. This is causing image broken for images, audio,  PDF & video.

Problem Statement:

  1. How to access assets or files in content-player without using file system path?

Impacted ares:

  1. Question-set

  2. EMLC content assests Images, Audios & Video.

  3. PDF

  4. Video(Mp4 or webm)

  5. HTML

Solution 1: 

Removing Cordova checks & remove pre-fixing  "file://" to the asses/file path while playing in mobile.

Solution 2: 

Use window.parent.Ionic.WebView.convertFileSrc(url);

main.js window.getLocalPath(path) { window.Ionic.WebView.convertFileSrc(path); }

Replace all the place where-ever we are referring "file://" by calling above function.
