I bought new Android phone and the only one application that I should take care is AnkiDroid. I don't want to lose my learning progress.
Naive placing of SD card into new phone doesn't work. AnkiDroid said something about incorrect
collection and cleanup
During cleanup AnkiDroid remove everything from
.apkg files for import without conformation.
Of course I've made copy beforehand:
$ adb pull /sdcard/AnkiDroid ~/tmp/
I placed latest backup to old SD card in new phone:
$ adb push ~/tmp/AnkiDroid/backup/collection-2017-01-30-12-34.apkg \ /sdcard/AnkiDroid/backup
and I chose to restore from this backup. Unfortunately I lost progress for current day, but fortunately not for 4 month!!
I recommend to follow official instructions from:
How can I copy my decks from an old device to a new device?
Method 2: Export > Import
Export your collection as a
.apkg file from your old device, copy it to your new device using
any method you like, and then import this file into your new device according to the importing
instructions in the manual.
