You need add xmlns attribute to your root element. Something like:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"   
    xmlns:app="http://schemas.android.com/apk/res/com.tutorialsbuzz.slidingtabdemo"

Try this code. and check if you have tabstrip.java file in your pakage. which is required for it to work properly

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_height="match_parent" android:layout_width="match_parent">

            <android.support.v7.widget.Toolbar
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:id="@+id/toolbar"
                android:background="@color/primary"
                android:minHeight="?attr/actionBarSize">
            </android.support.v7.widget.Toolbar>


            <com.example.SlidingTabLayout
                android:layout_below="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:id="@+id/sliding_tab">  
            </com.example.SlidingTabLayout>


            <android.support.v4.view.ViewPager
                android:id="@+id/pager"
                android:layout_below="@+id/sliding_tab"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

            </android.support.v4.view.ViewPager>
        </RelativeLayout>

with linearlayout it's working.Vasily Kabunov ur suggestion is no working — Sumit Kumawat, Feb 19 '16 at 05:58

You might need to follow this,

You need to add some content to parent node or issue with namespace

First node needs to add : xmlns:android="http://schemas.android.com/apk/res/android"

Check this stack answer.

Hope this helps.
