[AndroidRuntime] 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.

Kindly help on this.

CodePudding user response：

At first, you can debug to find which PendingIntent you used caused this error.

If it is created by yourself, you can try to set the flag as PendingIntentFlags.Immutable or the PendingIntentFlags.UpdateCurrent when you use the PendingIntent. For more information, you can check this case.

And if it is created by the nuget packages you used, you can try to upgrade the package's version to the newest one.

In addition, the library mentioned in the case's answer I provided above. It is the nuget package named Xamarin.AndroidX.Work.Runtime in the xamarin, you can install the last version in your project.
