Using an OBB (Opaque Binary Blob) file is mainly beneficial for apps like HiTV that provide extensive media content, such as movies, dramas, and live streaming. Since Google Play limits APK sizes to 100MB (previously 50MB), OBB allows storing additional assets like high-quality video previews, UI graphics, and other large data files, enabling a smoother user experience.

However, OBB files require additional handling, such as using the Google Play Expansion File API or a custom downloader. If your app targets devices below Android 2.3, compatibility issues may arise, and attempting to load an OBB file on such devices could lead to exceptions. To ensure a seamless experience for HiTV users, consider fallback mechanisms like streaming assets dynamically instead of relying solely on OBB storage.
