Targeting S+ (version 10000 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent

Question

Trying to update my application to Android S and running into some issues as the Title/error says. I get the error

Targeting S+ (version 10000 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 only have 1 PendingIntent within my code for notifications and I added the Flag

PendingIntent.getActivity(       mContext,       0 /* Request code */,       intentOptional.get(),       PendingIntent.FLAG_IMMUTABLE     ) 

Reading Google's documentation this should be all I need to for this security update within Android S. I did find a couple month old post on here that asked something similar and someone said to add WorkManager https://stackoverflow.com/a/67181567/4219444 into project even if you do not use it. So I added

def work_version = "2.7.0-alpha04"  implementation "androidx.work:work-runtime-ktx:$work_version" 

This didnt help at all as I still receive the error. Does anyone know if this is common issue with Android S upgrades or does it check libraries also? Stuck as the app just keeps crashing and not sure what to do.

I have created a application with none of my libraries and used the same PendingIntent and was able to run a basic hello world application with the pending intent. The full error I receive from the project I am trying to get to compile is:

Answer 1

It is solved by adding

implementation 'androidx.work:work-runtime:2.7.0-alpha05' 

in my gradle. (You can add the latest release version of this library)

Seems like it is a bug in workmanager. Check the bug fix in Version 2.7.0-alpha02
