Android unable to load class error

Question

I am trying to implement pull-to-refresh using github example https://github.com/chrisbanes/Android-PullToRefresh but when i am tring to implement the list view its giving me unable to load class master\library\src\com\handmark\pulltorefresh\library\pullToRefreshListView

I have imported library project into system and also placed the jar file.

I ran sample project which is using this library its working the screen shot of it is:

But when i am trying to implement this class to my project its giving class not found exception i have made one libs folder and put library.jar file in there and added it to build path but still on run time its throwing this error.

in my xml file i have put

<com.handmark.pulltorefresh.library.PullToRefreshListView
    android:id="@+id/listView1"
    android:divider="#E4E4E4"
    android:dividerHeight="2dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:cacheColorHint="#00000000"
    android:fadingEdge="none"
    android:fastScrollEnabled="false"
    android:footerDividersEnabled="false"
    android:headerDividersEnabled="false"
    android:smoothScrollbar="true" />

Answer 1

Finally got the solution of it

in place of adding jar files in lib and adding it to build path we have to put library project as dependent project

You have to add project here

RightClick:==> properties ==> Android ==>> Library (Add)

Answer 2

did you link the libs correctly?please check your IDE or your project.properties.
