未找到 Google Maps api v2 类

Question

我正在使用 google maps api v2，一切正常。今天早上我更新了sdk，现在地图不工作了。尝试了很多东西，比如再次导入 lib 项目，但似乎没有任何效果。请帮忙。

这是logcat的输出

Answer 1

在 Eclipse 中转到：

“项目”->“属性”->“Java 构建属性”

在“订购和导出”选项卡上，我在我的项目中选中了“Android 私有库”。我也为它引用的库项目做了这个。这修复了升级到 SDK 22 后我的类未找到错误。

Answer 2

您应该在地图项目中引用 google play services library 项目。

将您的库项目导入您的工作区。将其导入 Eclipse。

右键单击您的项目。转到属性。选择安卓。点击安卓。浏览并添加库项目。
