什么“无法实现ComponentInfo的活动”代表什么？

I am trying to develop Android app, something with GPS, and using Google Maps API v2. This error (bigger picture in link) is showing up and app crashes immidiately after run.

我正在尝试开发Android应用程序,使用GPS,并使用Google Maps API v2。此错误(链接中的大图)显示,并且应用程序在运行后立即崩溃。

And here's the AndroidManifest.xml file:

这是AndroidManifest.xml文件:

I am using 2 Java Activities like below

我正在使用2个Java活动,如下所示

Did you say you have two activities? If so, you haven't declared one of them in the manifest file.

你说你有两项活动吗?如果是这样,您还没有在清单文件中声明其中一个。
