how to resolve Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent

by

I am having an issue with firebase messaging service, when ever I receive a notification I get this error

java.lang.IllegalArgumentException: io.ohme.android.dev: 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.

in the fcmService I am already using FLAG_IMMUTABLE for pending intents. Not so sure where to make make changes.

gradle for reference

implementation("com.google.android.gms:play-services-vision:20.1.3")
implementation("com.google.firebase:firebase-bom:26.8.0")
implementation("com.google.firebase:firebase-auth-ktx")
implementation("com.firebaseui:firebase-ui-auth:7.2.0")
implementation ("androidx.work:work-runtime-ktx:2.8.1") // Added this as per some of the answers

    minSdk = 26
    targetSdk = 34
compileSdk = 34

this is the full error, please suggest what I can do to resolve this.

  • Have you tried updating from 21.0.1 to 23.2.1

  • Hello @EpicPandaForce thank you for responding, this is what I have in gradle for firebase messaging – ` implementation(“com.google.firebase:firebase-messaging”)`

    Sounds like you should update the BOM.

    – 

  • ok that makes sense, implementation(“com.google.firebase:firebase-bom:26.8.0”) this is what I have currently, will update to 32.3.1
