Hi,

first of all BIG THANKS for putting the code for "Anki Card Type for multiple-choice" on the Internet. Thanks for sharing. Card Type works beautifully on Windows Anki, a bit less in AnkiDroid (probably because there is no window.title property?). I wondered (before staring too take a hard look at the thing - I am not a programmer, but do fiddle with things a bit) if you would be so kind and maybe help me with the following:

• provide Card Type for a single correct answer - radio buttons,
• provide Card Type for a ordered multiple-choice answers (multiple, have to be in proper place, maybe by entering number before the answer( 1,2,3,4...),
• make these Card Types work in AnkiDroid.

The reason that I would like to have these Card Types are the exams I am preparing for (Microsoft). I usually read few books on subject, do a lot of work in labs I set up, and then prepare for exam using dumps. I copy these to Anki and prepare desks. Since Anki is such a super tool for learning by spaced repetition, this turns out to be great fun way.

Thanks again, have a really nice, pleasant day,

Seems there is no way to make this work right on AnkiDroid ;(... Found this post: https://groups.google.com/forum/#!topic/anki-android/Iqs-cZN5Lr4. In AnkiDriod WebView is re-created on each card to avoid memory-leak issue...
But how does close work then? Somehow it must be possible to transfer answers from front to back.

I'm slightly confused about the instructions.
I copy and pasted "Front Template" "Styling" and "Back Template" into Anki on my PC under "Card Types for Basic" but I don't know what to do with "Example Note" ? Some further instruction would be greatly appreciated!

Could you give some more details:

1. What fields do I need to make for the cards
2. How do I specify which answer is correct

When I tried to paste this code into Anki, and added the fields that I thought I needed, it didn't work.

I guess, in summary, please add some explanation on how to make this work! Thanks!

• I'm completely computer illiterate. I just started doing the Programming course on Khan academy... So, yeah!

This code works bad way. I've copy-pasted it's chunks under Windows, but each time I see BackSide after incorrect answer it paints randomly answer's in wrong colors. 👎

Thank you very much. This code works very good on AnkiDroid for windows and it works bad on AnkiDroid for Android

Thank you for the card template! I was asked to modify it a bit and shared it on https://ankiweb.net/shared/info/492884834
