Android Studio中的SupportMapFragment出现在片段上的错误

Question

我已经搜索了很多个小时和几天来找到答案，但仍然不能。我正在使用Android Studio（最新版本）IDE

我想创建一个地图视图（使用Google Maps API）到FragmentActivity的一部分的片段。

AndroidManifest更新了必要的权限和Google密钥。

正如您在输出中看到的，来自Google Map API的LatLng类在我创建实例时运行良好。 Lib被导入到libs文件夹中

请帮忙!!

Answer 1

Lib was imported on libs folder

的播放服务SDK是一个Android库项目，而不仅仅是一个JAR。从libs/中删除JAR并添加对Android库项目的引用。这样，你就可以获得该库项目定义的资源。
