Xamarin Android error MSB6006: "java.exe" exited with code 1

[rogerskk]

After adding the Geofence plugin 1.8.11 to my project I started getting the error "java.exe" exited with code 1 for the Xamarin Android project when trying to build. I remove it and then it builds and runs in the emulator just fine. I am using Visual Studio 2022 Preview 17.2.0 Preview 3.0, and building for Android 12.0 - API 31. I have the latest version of Java installed (18). I tried compiling in Visual Studio 2019, which succeeds - but when trying to debug in the Emulator I get the following error (including stack trace). I don't care which version of Visual Studio I use, I just want to be able to get it to work in at least one of them. And no my package name does not start with a capital letter. Also in VS 2019 to fix the issue below, I tried adding Exported=true in the Activity annotation but got the following error System.InvalidOperationException: Duplicate attribute - which from what I've read online is a bug in VS 2019 and can only find a fix for it in VS 2022.

I just encountered this issue too, after bumping my target version up. The problem is services and receivers need to have "exported" set explicitly now, and I can't figure out a way to make that modification myself, I think it needs to be fixed in this project.

I'm seeing this too. The issue lies with the GeoFenceBootReceiver.

It uses the BOOT_COMPLETED intent-filter, so needs [Service(Exported = true)] attribute added to the class.

There's no manual way to update the android manifest to do this so must be done in this package.
