在清单和 xml 文件中，我做了所有事情（这有效），但我的问题出在我的地图活动中！当我点击我的应用程序应该启动的按钮时，只有一个黑屏并且我的项目崩溃了:(这里的代码：

没有错误日志，很难解决问题。
这是一个例子。开始使用适用于 Android 应用程序的 Google MapV2。

注意：以上来自我自己的博客。

您的元标记必须是应用程序标记的子标记。

您需要扩展 StandardActivity而不是FragmentActivity因为您的 min sdk 不是 11 或以下

您应该使用 aMapFrament而不是SupportMapFragment.

<uses-library android:name="com.google.android.maps"> </uses-library>从清单中删除

确保您遵循所有步骤@

您没有阅读堆栈跟踪吗？它清楚地说：

未找到 API 密钥。检查它是否在 AndroidManifest.xml 的元素中

您在 Manifest 文件中使用的 API 密钥（“my api debug key (v2)”）无效。您必须在 API 控制台中创建一个并使用它。
