Android Google Maps [React Native?] "API key not found. Check that.." Error

Hi I am new to react native. I just made a new application. When I don't have a map component in my application and my other components work fine. However when I add this in my render(){return(..

  <MapView
    ref={ref => { this.map = ref; }}
    mapType={MAP_TYPES.TERRAIN}
    style={styles.map}
    initialRegion={this.state.region}
    onRegionChange={region => this.onRegionChange(region)}
  />

I get the error:

I did a search of the project folder to find a AndroidMainfest.xml and I found a couple. I changed the one in: \android\app\build\intermediates\manifests\full\debug

from this:

I even just tried it with only the meta-deta API Key one.

Some other information: I got the API key from here: https://developers.google.com/maps/documentation/android-api/signup.

After I changed it I just saved the file and restarted the simulator restarted the app with react-native run-android in the directory with command prompt. I'm not sure if this is the correct way to "Rebuild" the project.

I am using the Airbnb react-native-maps component that Facebook recommends using: https://github.com/airbnb/react-native-maps

I did the npm install react-native-maps --save and react-native link react-native-maps recently because this is a brand new project (error in the new version they provide or something?). The emulator is android 7.1.1.

Here is the SDK Manager for the android studio simulator:
