Example 20 with Media

use of com.ichi2.libanki.Media in project Anki-Android by ankidroid.

the class Media method mediaChangesZip.

/*
     * Media syncing: zips
     * ***********************************************************
     */
/**
 * Unlike python, our temp zip file will be on disk instead of in memory. This avoids storing
 * potentially large files in memory which is not feasible with Android's limited heap space.
 * <p>
 * Notes:
 * <p>
 * - The maximum size of the changes zip is decided by the constant SYNC_ZIP_SIZE. If a media file exceeds this
 * limit, only that file (in full) will be zipped to be sent to the server.
 * <p>
 * - This method will be repeatedly called from MediaSyncer until there are no more files (marked "dirty" in the DB)
 * to send.
 * <p>
 * - Since AnkiDroid avoids scanning the media directory on every sync, it is possible for a file to be marked as a
 * new addition but actually have been deleted (e.g., with a file manager). In this case we skip over the file
 * and mark it as removed in the database. (This behaviour differs from the desktop client).
 * <p>
