java - Android DrawerLayout Resource Not Found -


i working sdk minimum of api level: 10. so, using support v4 library create drawerlayout, doing:

manager = mainscreenactivity.getdevicemanager();     string[] drawerinfo = manager.getdrawerinfo();      drawerlayout mdrawerlayout = (drawerlayout) findviewbyid(r.id.drawer_layout);     listview mdrawerlist = (listview) findviewbyid(r.id.devices_left_drawer);      // set adapter list view     mdrawerlist.setadapter(new arrayadapter<string>(this, r.id.devices_left_drawer, drawerinfo));     // set list's click listener     mdrawerlist.setonitemclicklistener(new onitemclicklistener() {         @override         public void onitemclick(adapterview<?> parent, view view,                 int position, long id) {          }     });

xml: 

<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">      <framelayout         android:id="@+id/devices_content_frame"         android:layout_width="match_parent"         android:layout_height="match_parent"/>     <listview         android:id="@+id/devices_left_drawer"         android:layout_width="240dp"         android:layout_height="match_parent"         android:layout_gravity="left"         android:choicemode="singlechoice"         android:divider="@android:color/transparent"         android:dividerheight="0dp"         android:background="#111"/>  </android.support.v4.widget.drawerlayout>

i getting exception "resource$notfoundexception" when opened. strange thing is, let's devicemanager (my own custom class) has no devices. drawer works fine, extends , closes 100%. but, however, once devicemanager finds device , adds it's name (string) list , try add drawerlayout crashes open drawerlayout activity. (it crashes hardcoding strings it) what's wrong here?
