How to resolve "Missing PendingIntent mutability flag" lint warning in android api 30+?

Question

As soon as I updated the target SDK to 30 (Android R), a lint warning Missing PendingIntent mutability flag appeared on my PendingIntent.FLAG_UPDATE_CURRENT flag when I want to define PendingIntent.

How should I handle this lint with no effect on the app functionality?

Answer 1

You can set your pending intent as

val updatedPendingIntent = PendingIntent.getActivity(
   applicationContext,
   NOTIFICATION_REQUEST_CODE,
   updatedIntent,
   PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT // setting the mutability flag 
)

According to the docs here: https://developer.android.com/about/versions/12/behavior-changes-12#pending-intent-mutability

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.

Choose your flag accordingly.
