I can't run my android maps aplication on phone

Question

I developed an android maps application on Google API 2.1 update-1 platform. And it is the simplest code to show a map on the screen, there is no other things.

However, map doesn't shown on phone. The problem is, the same program runs on my android emulator right but it is not working on my android phone properly, I mean program starts on phone but I see only greeds instead of map. phone android version is th same, 2.1 update-1.

Please help me, Thanks.

If the same APK file works on the emulator but does not work on the phone, ensure that:

• The phone has a working Internet connection
• The phone's built-in Maps application works
