我只是按照非常简单的说明创建一个新的 Android 应用程序以将地图（使用此处的说明：https ://developers.google.com/maps/documentation/android/start ）加载到主屏幕中。我有以下错误：

我正在使用 IntelliJ IDEA 12，并且尝试将 google-play-services.jar 添加到模块中。

如果您的目标 API 级别 < 12，则需要为此添加支持库，因此显示地图的活动将扩展android.support.v4.app.FragmentActivity类。并且在您的布局地图片段类中必须是com.google.android.gms.maps.SupportMapFragment。例如

<fragment
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment" />
