I have made an android app having a map which runs fine in emulator and mobile. And I signed it to upload in play store. I even zip aligned it. Then I uploaded it in the playstore. But the map doesn't load when I download it. I have been taking help from this site: http://developer.android.com/tools/publishing/app-signing.html#releasemode
I have also followed the following two sites: Google maps v2 doesn't showing after publishing in play market
Google maps, Google store publish
But still, it's not working. Its been a great problem for me. Please anyone, with a higher degree of knowledge, help me. I am in big trouble.
