Google Map API v2 is not showing Map on device

I am running sample code that is provided on Google Map Documentation for Google Map Api v2 (https://developers.google.com/maps/documentation/android/start#specify_settings_

Answer 1

Most probably your problem will be solved when you make sure below mentioned things:

1. Activate Google Map API

2. Use correct package name while generating API Key (in my case this was the mistake) .. and this seems problem to your case also as package name appears to be wrong (com.example.mapdemo)

3. Make Sure you are using the correct keystore file for generating the SHA1

Hope this will be helpful.
