I am testing the sample google code on an actual device having 2.3.6.I thought it might be the problem with the key ,so I created different key on a different account through Google's API Console.Still the same problem "Google Maps Android API-Authorization Failure". Here is the log:

Any help would be appreciated.
Solved it.Very stupid mistake on my part.Used wrong api key.Was using the api key for the signed app.Replaced it with api key for debug keystore and solved the problem.
Had the same problem and @Sunkenglory 's answer is right, just to add some info for newbies like myself when I was looking for a solution.
On mac osX, my debug keystore was located here:
~/.android/debug.keystore
Go to that folder and run the following
keytool -list -v -keystore debug.keystore
That gave me the correct sha1 that I entered in the google console, and now it works.
