React native map-view not loading map

I was testing the new changes in my app on my android device and everything was ok, but when I turned on the internet so the google map could load nothing have changed. Is it some problem with my API key? I was using this code before and the map would always load normally.

<MapView
  style={{ flex: 1 }}
  region={this.state.place.coordinates}
  ref={(c)=> this._map = c}
  showsUserLocation={true} >
    {this.getMarkers()}
</MapView>
