Android GoogleMaps API v2身份验证错误，在AVD上运行时我没有收到错误，但在我的nexus 7上却收到身份验证错误

Question

I am developing an Android application which uses Google maps for android v2. The problem i having is that when i run it using the AVD in Eclipse i recieve no authentication error in the log cat output.

I am now testing my application on an Android tablet (nexus 7 2013) and i recieve this error when executing the application:

12-12 01:09:13.968: E/Google Maps Android API(14759): Authorization failure.  Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.
12-12 01:09:13.968: E/Google Maps Android API(14759): Ensure that the following correspond to what is in the API Console: Package Name: dcs.aber.ac.uk.cs211.group02, API Key: AIzaSyDcnzt6cdjEbCXSCRSTezmUHbaPW679if8, Certificate Fingerprint: 52FDB9ABBBAA062226834E35BF6A39FA2A3E27A7

I have tried to regen the API key, the one in the logcat matches the one provided in the google API console.

I have tried a clean project/clean install on the device several times, still no luck. The reast of the application works fine, only the map does not.

Here is my manifest.xml al the permissions seem ok.
