Did you give AnkiDroid microphone permission?

[snecker]

@david-allison yes, I did.

When I used "Check pronunciation" for the first time, AnkiDroid also required the microphone permission , I can record audio through "Check pronunciation" as expected after I gave the permission.

However，I can't record audio through pure javascript though I already gave AnkiDroid the permission .

Perhaps the permissions of a webView are different from those of the app itself？

~~@krmanik FYI~~

Whoops - not API related, sorry for the ping

@snecker Could you export a card with this problem and attach it as a .zip

[snecker]
