I have done one of those Maps tutorials too, and the differences that i can see is:
- You are missing two permissions in your manifest: ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION
- In my main.xml i have the com.google.android.maps.MapView inside a LinearLayout

 

[babyboss]

I have done modification accordingly, but still get the exactly same error as above. Could you send me a working version code? or make an attachment? Thank you.

 

[miXer]

Here is my eclipse project.

 

[babyboss]

First of all, thank you very much for the attachment. It works, and it doesn't show me stopped unexpectedly error. However, I get blank google map page, which doesn't show anything like the following:

By the way, I am in Asia region. Will that also be a factor?

 

[miXer]

Have you added your own Google Maps API key i main.xml? Google it too find out how.

 

[babyboss]

I did get the google MAPVIEW key, and inserted it into main.xml where you put "Your Google View Key"

 

[miXer]

Then i dont know. For me it runs fine in Norway

I had the same problems the first times I tried making an app using google maps, and realized the stupidest mistake. I didn't setup the emulator in AVD to be including Google API's, but a standard Android x.x. Rookie mistake, but easy to overlook.
