android - 应用程序意外停止

Question

我是 android 的新手，正在开发一个使用 google maps API 的应用程序。

在运行应用程序时出现错误:

the application has stopped unexpectedly

这是我在 logcat 文件中的内容:

您必须将 Activity SurveyActivity 添加到您的 AndroidManifest.xml 文件中。

您可能还忘记了将 Google map 库添加到 list 中:

<application>
    <uses-library android:name="com.google.android.maps" />
</application>
