Android Directory is Inaccessible (version 2.17.6)

Since you aren’t synced already, the easiest method is #1 (Full Storage Access · ankidroid/Anki-Android Wiki · GitHub) –

  • Backup your AnkiDroid folder
  • Install a github parallel build, which can still access the old file location
  • Sync to upload your collection to AnkiWeb, which it is good to be doing anyway, so you have a backup! (AnkiDroid 2.17 User Manual)
    • If you have a lot of media, it may take a few tries for all of your media to sync
  • Then in your main install, setup syncing to download your collection from AnkiWeb
