I've got a debugger stop when I'm trying to run in Android or when I'm running the activity from file:/// (basically, because we're using Cordova, running on Android means running in file:///).

The error is: TypeError: Failed to register a ServiceWorker: The URL protocol of the current origin ('file://') is not supported. Is there some restriction to use ReactJS on file:/// ? @thingthing any idea?

Look like this error is not new (tested on the previous version of Exerciser).

Can't build the app, look like there is a missing module/directory:

Module not found: Error: Can't resolve './media/defaultExerciseThumbnail/videos' in '/home/lionel/src/olpc/ExerciserReact/src'

The thumbnail update is possible but if you change something (crop, rotate, flip, ...) and cancel your change, there is now an error message in the console:

The error appears also on other editor usage (not only in thumbnail)

You can perfectly disable the serviceworker if you want. To do it, in the file index.js, you can

// import registerServiceWorker from './registerServiceWorker';
import { unregister } from registerServiceWorker;
...
// registerServiceWorker();
unregister();

This will make sure to clean all serviceWorker that were previously registered if any were, if not, it will just do nothing.

Thanks @thingthing, @AvinashAgarwal14 could you try to remove the Service Worker and test if everything works fine without it?
In fact, I'm not sure at all that Service Worker features of offline handling comes from free. I mean, if you don't explicitly use it, caching will not happen automatically in the background. So, if there is no use of Service Worker features in the current code of Exerciser, I guess we could disable it without risk.

Nice job.
