Google map API Key

In case you want to use MapView in your android app, you need to have a  map key .
the next step will describe how to do it in your debug environment.

search for the debug.keystore file , in my Win7 its located at:
C:\Users\yanivt\.android

open cmd windows.
cd C:\Users\yanivt\.android


C:\Users\yanivt\.android>"C:\Program Files (x86)\Java\jdk1.6.0_35\jre\bin\keytool.exe" -list -alias
androiddebugkey -keystore debug.keystore -storepass android -keypass android

you should get somthing like this
