No Map On Emulator

No Map On AVD Emulator or Emulator screen display blank grid screen. When I first started developing android app which display Google map on android device, I encounter this problem. I had done everything which I read on google android developer site for integrating Goolge Map in my application, but still I was not able to see map on emulator. Only square type grid screen (as seen in image) appears on emulator. 

If you have same problem than no need to worry. Your application was working fine. The problem is with google map api key. Either you had not added google map api key in your program or you may have given wrong api key. Try obtaining new google map api key and integrate it to your application. If you are new and don't know about google map api key and how to obtain it, than check this post Google Map API For Android App.

Problem:
No map on emulator.

Solution:
Add Google map api to program.
Or
Try obtaining new google map api key.
