2.0.0-alpha.2

Take a look at the migration guide

Added

• Support for the new Publication model using the Content Protection for DRM rights and the Fetcher for resource access.
• (Experimental) New Fragment implementations as an alternative to the legacy Activity ones (contributed by @johanpoirier).
  • The fragments are chromeless, to let you customize the reading UX.
  • To create the fragments use the matching factory such as EpubNavigatorFragment.createFactory(), as showcased in R2EpubActivity.
  • At the moment, highlights and TTS are not yet supported in the new EPUB navigator Fragment.
  • This is now the recommended way to integrate Readium in your applications.

Changed

• currentLocator is now a StateFlow instead of LiveData, to better support chromeless navigators such as an audiobook navigator.
  • If you were observing currentLocator in a UI context, you can continue to do so with currentLocator.asLiveData().
• Improvements to the PDF navigator:
  • The navigator doesn't require PDF publications to be served from an HTTP server anymore. A side effect is that the navigator is now able to open larger PDF files.
  • PdfNavigatorFragment.Listener::onResourceLoadFailed() can be used to report fatal errors to the user, such as when trying to open a PDF document that is too large for the available memory.
  • A dedicated PdfNavigatorFragment.createFactory() was added, which deprecates the use of NavigatorFragmentFactory.

Fixed

• Prevent switching to the next resource by mistake when scrolling through an EPUB resource in scroll mode.
