Google Map API V2 Map Is Not Visible

Question

I tried a lot of things which to fix it but, I still can't see the map. I'm sure that my ApiKey is true and Google Maps Android Api v2 is active.

If I try it on emulator, it crashes. But if I try it on a real device it works, but i can't see the map, only blank plain.

Answer 1

make sure you installed google play services. you can follow this tutorial http://wptrafficanalyzer.in/blog/google-maps-in-android-application-with-new-google-maps-android-api-v2-using-supportmapfragment/

Answer 2

如果仅出于调试目的而生成API密钥，请确保您的设备执行应用程序的调试版本。

Answer 3

You are using Activity (not FragmentActivity) with SupportMapFragment, and I doubt that will work. Which version of android target are you using? before android 4 you must inckude compatibility library too. If you are in debug you have to generate key from debug keystore signature that is the default eclipse use, inside eclipse android settings you fine the debug keystore location,
