Problem

Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent. I got it after updating target SDK to 31. the error always come after AlarmPingSender. But i dont know any class that used AlarmPingSender.

    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.

What I Already done

  • Upgrade WorkManager to 2.7.0
  • set AllProject to force use WorkManager to 2.7.0
  • change all existing PendingIntent to use FLAG_IMMUTABLE
  • there's old code that still use gcm and disable it
  • Updating all Firebase package (some said its because of later version of analytics)

Library Used

  • OneSignal
  • Qiscus
  • Firebase
  • WorkManager

Add the following to your build.gradle(app) dependencies.

dependencies {
  // For Java
  implementation 'androidx.work:work-runtime:2.7.1' 

  // For Kotlin
  implementation 'androidx.work:work-runtime-ktx:2.7.1'
}

Possible solution

Upgrade google analytics to firebase analaytics. Hope it'll solve your problems.Also upgrade all the library what're you using.

For me below solutions solve the problem.

Add PendingIntent.FLAG_IMMUTABLE to your pending intents.

Here is an example -

PendingIntent pendingIntent = PendingIntent.getActivity(this, alarmID, notificationIntent, PendingIntent.FLAG_IMMUTABLE);

For further information follow this link - https://developer.android.com/reference/android/app/PendingIntent#FLAG_IMMUTABLE

I had this crash but no 3rd party libraries. Adding this import with the latest version will fix the crash.

implementation 'androidx.work:work-runtime-ktx:2.7.0-beta01'

in addition to others' answers I changed :

implementation 'com.google.firebase:firebase-messaging:20.0.0'

to :

implementation 'com.google.firebase:firebase-messaging:23.0.0'

and its working now.

This might be the issue with the library version. If you have older version libraries in your project then you have to update it to the latest version.

So, update the work runtime and firebase messaging library version as follows,

dependencies {
    // For Java
    implementation 'androidx.work:work-runtime:2.7.1' 
    // For Kotlin
    implementation 'androidx.work:work-runtime-ktx:2.7.1'
    implementation 'com.google.firebase:firebase-messaging:23.0.0'
    ...
}

Also, ensure that the pending intent code is something like this,

PendingIntent pendingIntent = PendingIntent.getActivity(this, alarmID, notificationIntent, PendingIntent.FLAG_IMMUTABLE);
