尝试使用适用于 Android 的 Google Maps v2 API，它一直告诉我找不到我的 API 密钥。我尝试过其他帖子的建议，但没有任何效果。我刚刚创建了一个新的 API 密钥来验证该密钥没有缺陷。我还使用了 Google 设置文档中指定的代码，但仍然无法正常工作。以下是所有相关文件。谢谢。

错误消息中的有用提示说：

<meta-data android:name="com.google.android.maps.v2.API_KEY" 
           android:value="your API key"/>

你的代码说：

<meta_data android:name="com.google.android.maps.v2.API_KEY"
           android:value="xxxxxx"/>

指出不同？将您的更改_为-.
