Use your main packet name for generate key.
For example: im my project, google map v2 is in com.ftravelbook.googlemapv2 but when generate key, you must use your main packet name (com.ftravelbook) here are some screenshots:

I was also having the same problem because i have generated key by making on google maps api v2 on.It is used for web not for mobile.

For android device you have to make a google maps android api v2 on and generate your key

Is your map API key for your debugbuilds or your release builds? The key is based on your keystore, which is different between your debug and release build. Your release key for google maps won't work if you're debugging your app, and vice versa.

But are you running the app in release mode? Cause if you're not, it will show a blank screen like you said. – Sander van't Veer May 16 '13 at 14:48

make sure your certificate must be release , not debug and map key generate with release certificate .. – mohsin raza Jul 29 '13 at 10:17
