I am stuck with this problem when I run my project in eclipse, it shows the map correctly, but when I upload it to the Google Play Store, and when I install it on my device, it shows a blank map, I don’t know what the problem is , my card key is correct, the package name is correct, I also generate a new card key and try, but it also does not work. I do not know what's the problem.
Please follow the checklist:
1) Sign the app with the new .keystore.
2) Use SHA1 of the new .keystore.
3) The card key must be executed using this SHA1.
4) Google, , Android Maps V2.
,
Google Map Android API v2
This problem is because of map api key.
