I am considering buying a secondhand ereader (BOOX nova plus) for the specific purpose of using it for ANKI. For some reason, its not so easy to find out which versions of anki are compatible with specific android OS versions. I am wondering if I will have any problems with this because it is only Android version 6. I make anki cards on my MAC computer which has the most recent anki version downloaded on it.
Android 6 will work fine as long as you can install APKs. We have an e-reader mode in the Advanced settings which will improve your experience with the device.
We aim to support old devices for as long as feasible.
AnkiDroid 2.15.0 will drop support for anything below Android 5.0 (2014), which was a very difficult decision to make.
I don’t expect that we’ll drop support for Android 6 any time soon. Even if we do, older versions of AnkiDroid will always be available from our GitHub.
