I'm trying to implement a Tap & Pay application and therefor need to communicate with a POS Terminal. In order to do so, the device needs to set my application as the default application for Tap & Pay functionalities. Whether trying to ask the user to set it programmatically or via settings app, android Settings crashes.
I figured it has something to do with the manifest file since the crash apparently occurs during the process of listing the tap & pay apps.
I've followed the instructions on host based card emulation I've found on the android developer page https://developer.android.com/guide/topics/connectivity/nfc/hce
manifest.xml:
<?xml version="1.0" encoding="utf-8"?>

I'm currently testing the application on a Google Pixel running Android 8.1.0
I hope someone has an idea what could cause the crash, thanks in advance!
