Have you added your MAP KEY in your manifest file ? Also post your `MainActivity.java` file code. — GrIsHu, Jul 26 '13 at 12:43

Go to "Properties" of the project.
Select "Java Build Path"
Select "Order and Export" Tab
You should see the selected project's "src" and "gen" paths and dependencies here.
The order how they listed were first "src" and then "gen" path
I switch them, so that "gen" folder is build before the "src"

Still look at the Properties, instead of switch the positions, try to select all the libs.

I did this and it solves my problem.

enter image description here

Notice: You can run the Map API sample code now, but the Google Map app in emulator still shows nothing. If you want to run this app, you need to install Google Play Service app first.
