The given line #63 is the tag of the Fragment:

<fragment        
android:name="com..bucp.BanlistFragment"
android:id="@+id/banl_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout="@layout/banlist_fragment" />

The fragment file itselve contains:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:orientation="vertical"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:paddingLeft="8dp"
         android:paddingRight="8dp">

     <ListView android:id="@id/android:list"
               android:layout_width="match_parent"
               android:layout_height="match_parent"
               android:background="#00FF00"
               android:layout_weight="1"
               android:drawSelectorOnTop="false"/>

     <TextView android:id="@id/android:empty"
               android:layout_width="match_parent"
               android:layout_height="match_parent"
               android:background="#FF0000"
               android:text="No data"/>
</LinearLayout>

And the fragment class just contains

@Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  ListAdapter myListAdapter = new ArrayAdapter<String>(
    getActivity(),
    android.R.layout.simple_list_item_1,
    month);
  setListAdapter(myListAdapter);
 }

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
     View tmp_view = inflater.inflate(R.layout.banlist_fragment, container, false);
     ListView list = (ListView) tmp_view.findViewById(android.R.id.list);
  return list;
 }

Answer 1

in stack trace you have: Caused by: java.lang.ClassCastException: com.fr34kyd3v.bucp.BanlistFragment cannot be cast to android.app.Fragment

I’m guessing, maybe your BanlistFragment class extends Fragment from support library (android.support.v4.app.Fragment) and activity tries to “handle it natively” not with support library?
To get sth more than guess provide source code for BanlistFragment.
