Android 12 Kotlin - Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable

Issue

This is the code for pendingIntent:

val pi =
    PendingIntent.getActivity(
        applicationContext,
        0,
        ii,
        PendingIntent.FLAG_UPDATE_CURRENT
    )

I'm getting this error when using it:

java.lang.IllegalArgumentException: de.xxx.xxx: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

I still need the activity to be updated so how can I add this FLAG_IMMUTABLE or FLAG_MUTABLE what ever the hell this is and still be able to update the activity? Based on this answer I tried:

val pi =
    PendingIntent.getActivity(
        applicationContext,
        0,
        ii,
        PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_IMMUTABLE
    )

but this gives syntax error!

So how should the code look?

Solution

Based on this answer

The code presently shown in that question and answer are in Java. You are writing in Kotlin.

In Kotlin, use the or bitwise operator:

val pi =
    PendingIntent.getActivity(
        applicationContext,
        0,
        ii,
        PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE
    )
