• Save Lectures for Offline Viewing on the Android App

    If you plan on being disconnected from the internet, you can save individual lectures, sections, or an entire course for offline viewing on the Android mobile app.  Due to piracy concerns, you can only access a Udemy course within the app, since the downloaded offline content is encrypted. Once the course is fully downloaded, you can go to Ready offline course on the My Courses tab to start learning. 

    Download a Single Lecture
    You can download a single lecture from your Android device in a couple of ways:

    1) From the Course Curriculum, tap on the download icon , which appears beside the lecture title.


    2) Go to the lecture, tap the ellipses at the upper-right corner and choose Save for Offline.


    After you download a lecture for offline viewing a trash bin icon will appear beside it. If you decide to delete the saved lecture, then you can do so by tapping on the trash bin icon. You can also find the Delete Offline content option in the lecture options. For more information on how to delete saved lectures from your device, please refer to this article.

    Download a Section for Offline Viewing
    You can also select all the lectures in a particular section for download by tapping the download icon in the section title.
