在Android中使用Google Maps v2

Question

我正在尝试将Google地图集成到我的Android应用程序中.我遵循了这个教程:https://blog-emildesign.rhcloud.com/？p = 435.我按照建议做了一切.这些是错误日志中的错误:

E/Google Maps Android API(28238): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
E/Google Maps Android API(28238): Authorization failure.  Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.
E/Google Maps Android API(28238): Ensure that the following correspond to what is in the API Console: Package Name: com.example.kontrollen, API Key: xxxxxxxxxxxxxx, Certificate Fingerprint: xxxxxxxxxxxxxxxxxxxxxxx

这是我的谷歌帐户:

你有什么想法我能做什么？

这是我的AndroidManifest:

  <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.kontrollen"
    android:versionCode="1"

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
