Android Question NB6 and Android S+ (version 31+) Crash

Jack Cole · Jun 1, 2022

Targeting SDK level 31+ gives me a crash when trying to fire a notification using NB6.

Caused by: java.lang.IllegalArgumentException: b4a.example3: 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.

at android.app.PendingIntent.getActivity(PendingIntent.java:408)
... 32 more

Is there a manifest change that would fix it or is a library update needed?

It should work. Are you using B4A v11.5?

Yes, I am. I just tried the example app for NB6. It doesn't work when you set the targetSDK to 31+.

Not sure in what thread I’ve read it these days, but check again the android.jar / targetSDKversion… tutorial
There’s two new sentences regarding SDK 31. one of that lines says:
31 - Push notifications should be sent as high priority messages.

So, try to set priority to high.

Jack Cole · Jun 5, 2022

Yeah, doesn't make a difference for the crash. I tried the High Priority Notification in the NB6 example app. Same crash.

You are most probably using an old version of NB6.
The latest version is attached (v1.02). Replace the one in your internal libraries folder.

Jack Cole · Jun 5, 2022

That is the version I have; however, you have provided the solution. The example app that comes with NB6 actually uses a class not the library. I removed the class from the project and used the lib instead. It is now working.
