Another way of finding out your key information is to go to your java folder, for me it was at

C:\Program Files\Java\jdk1.8.0_60\bin 

and run the following command

keytool -list -v -keystore "USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android 

from the command you can easily see that keystore address is "c:\users/<%mylogin%>.android\debug.keystore" , alias is "androiddebugkey" store password is "android" key password is "android"

This is the default configuration from the Android 'Get API Key' documentation. https://developers.google.com/maps/documentation/android-api/signup
