Answer 1

这是因为你没添加进去，或者eclipse还没检测到你新添加的包；一般来说有这么几个方法：1、1、eclipse--->Project--------->clean
2、修改项目classpath文件,直接从其他正常项目里面把
<classpathentry kind="lib" path ="自定义jar的地址" />
修改成
<classpathentry kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>
3、修改default.properties为你目前使用的SDK版本号

Answer 2

你用的adt應該是新版本的，不需要build to path,在項目根目錄下建立一個Libs的文件夾，吧jar包放進去就可以了。
