[BUG]: AnkiDroid error when interacting with the API

[warleysr]

Checked for duplicates?

• This issue is not a duplicate

Does it also happen in the desktop version?

• This bug does not occur in the latest version of Anki

What are the steps to reproduce this bug?

I'm creating an app that queries AnkiDroid database to get card content, on my main screen I show the deck list to the user. I have a instance of AddContentApi and call the getDeckList() method. Sometimes when I launch my app a Toast from AnkiDroid appears saying that some error ocurred and a report was being generated.

UPDATE:
The AnkiDroid toast keeps appearing very often, sometimes when getting the deck list or when reviewing a card. Checking the Logcat I got this error:

Expected behaviour

Do not receive error messages when interacting with the API.

Actual behaviour

Toast messages on my app saying that a report is being generated, when I return to the AnkiDroid app a popup asks me if I want to send the report to developers. Even though the error occurs getting the deck list still works.
