Localelist init: IllegalArgumentException: list[1] is a repetition-CodePudding

I have recently noticed a lot of these crashes in my app. I am not able to reproduce it myself.

Any idea what the issue might be? I think it might happen when a bottom sheet dialog is about to be shown.

For reference my app supports 3 languages (English, Spanish and Bulgarian)

Exception java.lang.IllegalArgumentException: list[1] is a repetition

CodePudding user response：

Fixed by updating to androidx.appcompat:appcompat:1.6.0-alpha04.

I was using androidx.appcompat:appcompat:1.6.0-alpha01, and according to this issue, versions below 1.6.0-alpha02 causes a crash when setting a locale from app that is part of the system languages.
