I do not use getSupportFragmentManager() or getFragmentManager() methods in my code. 
I use addition lib "sliding menu". 
Erorr ocured in this code 

```
slidingMenu.setMenu(R.layout.slidingmenu);

```

where i call next method of slidingmenu library 

```
public void setMenu(int res) {
    setMenu(LayoutInflater.from(getContext()).inflate(res, null));
}

```

My **R.layout.slidingmenu** file 

```
 <?xml version="1.0" encoding="utf-8"?> 
  <fragment   
    xmlns:android="schemas.android.com/apk/res/android"
     android:name="com.example.Catholic_app.Menu.SlidingMenuFragment"
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
    android:id="@+id/slidingmenu"> </fragment>

```

P.s. support-library-v4 has been already added
