i don't understand why have exception, included jar in project properties...

here xml file :

<android.support.v4.widget.drawerlayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/drawer_layout"     android:layout_width="match_parent"     android:layout_height="match_parent">      <!-- main content view -->     <framelayout         android:id="@+id/content_frame"         android:layout_width="match_parent"         android:layout_height="match_parent" />      <!-- navigation drawer -->     <listview android:id="@+id/left_drawer"         android:layout_width="240dp"         android:layout_height="match_parent"         android:layout_gravity="start"         android:choicemode="singlechoice"         android:divider="@android:color/transparent"         android:dividerheight="0dp"         android:background="#111"/>  </android.support.v4.widget.drawerlayout>
