Question

此代码存在问题，“无法解析方法getMap（）。我没有找到问题所在，请在代码方面需要帮助，我使用Android Studio，并且需要使用Json进行标记位置。我不明白如何根据太新的更改来更新此代码。请根据新代码更正此代码。

我相信您已经升级了Google Play服务的依存关系。先前弃用的getMap（）函数在Google Play服务SDK中不再可用。（仍可从提供给Android设备的Google Play服务APK中获得它。）自2014年12月起，不赞成使用getMap（）函数。有关将getMap（）转换为getMapAsync（）的帮助，请参见发布博客。更多信息https://developers.google.com/maps/documentation/android-sdk/releases
