在运行或调试通过Eclipse中你的应用程序与将被自动创建调试密钥签名。这是不一样的，你签释放它，当你的应用程序中的关键。

When you run or debug through Eclipse your app is signed with your debug key which will have been automatically created. It is not the same as the key you sign your app with when releasing it.

您需要使用您的调试键获得一个API密钥。

You need to get an API key using your debug key.

见获取SDK调试证书的MD5指纹一节<一href="http://$c$c.google.com/android/add-ons/google-apis/mapkey.html">http://$c$c.google.com/android/add-ons/google-apis/mapkey.html

See the 'Getting the MD5 Fingerprint of the SDK Debug Certificate' section on http://code.google.com/android/add-ons/google-apis/mapkey.html

一旦你准备好释放你的应用程序，您更换调试API密钥与当前正在使用的API密钥。

Once you are ready to release your app, you replace the debug API key with the API key you are currently using.
