The android issue tracker in the AndroidX Datastor component is probably the best place to ask that.

I figured out that the problem is because am creating multiple instance of my preference class.

How can i stop this.

A singleton class maybe. But how to access context in singleton class.

appCtx

with Splitties App Context

Here's the link: https://github.com/LouisCAD/Splitties/tree/main/modules/appctx

BTW, there's also a library module in Splitties for type-safe and key-safe SharedPreferences (named Preferences), though I'd recommend using AndroidX Datastore anyday because of performance problems in SharedPreferences in the Android platform that might even lead to ANRs.

Thanks. Will have a look.
