title: Android Maps v2 Couldn't get connection factory client
body: <p>I have a problem. I am getting a blank google map. I tried everything around the net. But nothing seems to solve this issue. I have pasted the logcat below. I have tried both debug key and release key. But both are not working. The map is not working. I just get a grey background with Google written below :(  Please help </p>

  <p>[UPDATE]: I tried generating the sha1fingerprint again. I observed that the signature algorithm used is SHA256withRSA where as the example in the <a href="https://developers.google.com/maps/documentation/android/start#displaying_certificate_information" rel="nofollow">google dev site</a> show SHA1withRSA could this be causing any problem?</p>
