here toolbar (tool_bar.xml)

<android.support.v7.widget.toolbar android:layout_width="match_parent" android:layout_height="?attr/actionbarsize" android:background="@color/primary" android:elevation="4dp" android:theme="@style/themeoverlay.appcompat.dark" android:popuptheme="@style/themeoverlay.appcompat.light" android:fitssystemwindows="true" xmlns:android="http://schemas.android.com/apk/res/android"> </android.support.v7.widget.toolbar>

here activity main

<android.support.v4.widget.drawerlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/drawer" android:fitssystemwindows="true">  <linearlayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical">      <include         android:id="@+id/tool_bar"         layout="@layout/tool_bar">     </include>      <framelayout         android:id="@+id/fragment_container"         android:layout_width="match_parent"         android:layout_height="match_parent">      </framelayout>  </linearlayout>  <android.support.design.widget.navigationview     android:id="@+id/navigation_view"     android:layout_width="wrap_content"     android:layout_height="match_parent"     android:layout_gravity="start"     app:headerlayout="@layout/drawer_header"     app:menu="@menu/drawer"/>

here line of code throws exception

// initialise , set toolbar actionbar toolbar = (toolbar) findviewbyid(r.id.tool_bar); setsupportactionbar(toolbar);

and

maxbleggi.afstudentplanner.activities.mainactivity.oncreate(mainactivity.java:104)

is line specifically

 setsupportactionbar(toolbar);
