Hi friends, tried migrating to DataStore from SharedPreferences but

createDataStore

method not found. I already added the library on Gradle. I’m following Google’s documentation by the way

Not sure which version you are using, but there's something about this in the Release Notes of DataStore for the `alpha07`: https://developer.android.com/jetpack/androidx/releases/datastore#1.0.0-alpha07

Thanks I’m checking this one https://android-developers.googleblog.com/2020/09/prefer-storing-data-with-jetpack.html. Do you have any idea how to migrate from SharedPreferences using this latest syntax?

Does this work:

val Context.myDataStore by preferencesDataStore(
    name = "settings",
    produceMigrations = { context ->
        listOf(
            SharedPreferencesMigration(context, "settings")
        )
    }
)

?

@patrick no it doesn’t work I’m sorry

In your context it could look somewhat like this:

val Context.myDataStore by preferencesDataStore(
    name = "filename",
    produceMigrations = { context ->
        listOf(
            SharedPreferencesMigration(context, "settings")
        )
    }
)

object OnlineJobPreferences{

    fun save(context: Context, jobPreferences: String){
        val dataStore = context.myDataStore
        dataStore.updateData { ... }
    }
}

You can access the datastore anywhere in your codebase by calling

myDataStore

on a context and the migration should happen automatically

@patrick thanks your syntax worked already. Does it migrate all the stored values from my old SharedPreferences, or should do it manually?

It should work automatically you just need to use the datastore (reading or writing) as I understood it from the docs

@patrick appreciate the help. Thank you so much!
