Which Google service is responsible for emergency notifications?

I have an app that blocks notifications. I want to let emergency warnings through (like tornado warnings).

The services that have google in their name are:

  • “Files by Google” – com.google.android.apps.nbu.files
  • “Goggles” – com.google.android.apps.unveil
  • “Hangouts” – com.google.android.talk
  • “Home” – com.google.android.apps.chromecast.app
  • “Maps” – com.google.android.apps.maps
  • “News & Weather” com.google.andoird.apps.genie.geniewidget – Maybe this is it?
  • “Personal Safety” com.google.android.apps.safetyhub
  • “Google” – com.google.android.googlequicksearchbox
  • “Google Go” – com.google.android.apps.searchlite
  • “Google News” – com.google.android.apps.magazines
  • “Google Play” – com.google.android.apps.walletnfcrel
  • “Google Play Games” – com.google.android.play.games
  • “Google Play Music” – com.google.android.music
  • “Google Play Store” – come.android.vending
  • “Google TV” – com.google.android.videos

I’m using a pixel xl 2.

Also, how do I test if I have the settings correct? Is there a way to fake an emergency broadcast to myself?
