the error class not found exception is when actitvity is not declared in manifest if you have declared it and then also error comes please please check you may have included a jar file twice in your project

Your mentioned code is right But i have two doubt is that
1. Google MAP API
Ans .To get Google MAP API Here
2. Check Emulator's Internet.
Ans . Open CMD

Move :
<uses-library android:name="com.google.android.maps" />
within the application tag. You have written outside the application tag in manifest file.
For your second problem: I am sure you have copied the map key from some where else. This is causing only blank screen on emulator. Try to generate your own Map Key following:
