Due to Google's requirement to target Android 14 (API level 34), I have updated the target version of my Xamarin. Forms project accordingly. However, when I run the project, I'm encountering the following error.

I also tested the latest Zebra sample (version 2.0.1.116, released in May 2023) to verify the issue, and it occurs there as well.

Could anyone provide guidance on this? Any feedback would be greatly appreciated.

Steps to Reproduce:

1. Download the latest project from the link below.
2. Change the target version in the manifest file to 34.
3. Run the project on a device running Android 14.

I think this is the issue discussed here: https://stackoverflow.com/questions/77235063/one-of-receiver-exported-or-receiver-not-exported-should-be-specified-when-a-rec

Are you able to include the workaround suggested in the sample code and retest ?

To allow the broadcast receiver to receive broadcasts from other apps, register the receiver using the following code:

context.registerReceiver(broadcastReceiver, intentFilter, RECEIVER_EXPORTED);

I have same problem in Java. But i canť test it without access to source code when brodcast is not declared via Android manifest but dynamically in source code. Or?

Is this how you handle it? https://developer.android.com/about/versions/14/behavior-changes-14#runtime-receivers-exported
