NCG Android SDK 2.19.0

Content SecurityMulti-DRMRelease Notes

← What's New

  • Updated **NcgEpubFile.open(String cID, String path)** function:

    • Added cID (Content ID) parameter to the NcgEpubFile.open() function.

    • When the same Content ID is reused, internal file open and DRM info parsing are skipped, improving performance.

  • Added Multi-thread Support for **NcgEpubFile**:

    • NcgEpubFile class now supports multi-threaded usage.

    • Each NcgEpubFile instance must be operated by a single thread — multiple threads reading from the same open() call are not supported.

  • Updated **NcgEpubFile.close()** call behavior:

    • close() should no longer be called immediately after each open(). Instead, call close() only when all file operations are complete.

    • For contents sharing the same cID, use open() to open the next file without calling close() in between.

    • Example: When an EPUB file contains multiple internal files, call open() for each file as needed, and call close() only once when all files within the EPUB have been processed.
