そのビルドパスを考えてみると思いますが、完全なプロジェクトをビルドパスに含めるのはこれが初めてなので、それについての経験はありません.インポートは正常に機能します。

アクティビティ：

package com.gps.gpsclient;

Clean and Build

If that doesnt help then restart eclipse and clean and build again.

EDIT:

You said:

.But when i include this project to buildpath of my project,i get a NoClassDefError.

It seems that you have some library project included in your build path.You need to mark this external project as a library project.To do that,after importing the project into the workspace go to your main project.Right Click and go to properties.. and select the "Android" group on the left.On the right pane you will find a Library panel in the extreme bottom.Click on add and find and add the other project to it and mark it as a library project.

enter image description here

After doing this,clean build and do what i said earlier.Refer this Q/A as well.

If this solves your issue mark it as an answer.
