title: APIKey Android Google Map
body: <p><br>
  I'am using Android Studio right now, and I decied to make an app that use Google Map API.
  <br>
  My app is very simple, I have a AutoCompleteTextView. Everytime I write something in AutoCompleteTextView, it will automatic suggest some location that is the same with the name I text.
  <br></p>
  
  <p>I follow how to get the api key of google, and I did exactly. But when I text, it not suggest anything. 
  <br></p>
  
  <p>I thought my code is wrong, but when I change my Api key by another api key of someone I took in the internet. It worked fine.
  <br></p>
  
  <p>Please tell me why ?

  Sorry about my English, it is not native.</p>
