I'm recieving the above error when deploying my Xamarin Android application using Visual Studio in debug mode, the compile process completes fine but I can't deploy.

The app runs fine in Android 8.1.0 but not in any other lower version.

Error:

 The initialization ContentProvider will call FacebookSdk.sdkInitialize automatically
 with the application context. This config is merged in with the host app's manifest,
 but there can only be one provider with the same authority activated at any given
 point; so if the end user has two or more different apps that use Facebook SDK, only the
 first one will be able to use the provider. To work around this problem, we use the
 following placeholder in the authority to identify each host application as if it was
 a completely different provider.

Anyone here knows, what do i need to do?

I took some screenshots to add here:

Finally I was able to solve the problem, the solution was to change the prefix name of the HCECardService to lowecase.

Before: Empresa1.SMPay.HCECardService

After: empresa1.smpay.HCECardService

[Service(Exported = true, Enabled = true, Permission = "android.permission.BIND_NFC_SERVICE", Name = "empresa1.smpay.HCECardService"), IntentFilter(new "android.nfc.cardemulation.action.HOST_APDU_SERVICE" , Categories = new "android.intent.category.DEFAULT" ),
