Method responsible for forming the list

private void getData(){
    
     db=new DB(getActivity());
     db.open();
        
    c = db.getData(orderStatus);

                 lm = getLoaderManager();
    lm.initLoader(0, null, this);
    
    if(c!=null && c.getCount()>0){
          
                 while(c.moveToNext()){
        String[] from = new String[] {DB.COLUMN_EXT_ID};
        int[] to = new int[] {R.id.tvExId};
        adapter = new CustomAdapterOrders(getActivity(), R.layout.orders_list, c, from, to,lm,db,orderStatus,tehGuid,tehToken);
        setListAdapter(adapter);
                        }
     }

CursorLoader

@Override
  public Loader<Cursor> onCreateLoader(int id, Bundle args) {
    // TODO Auto-generated method stub
     return new MyCursorLoader(getActivity(), db);
  }

  @Override
  public void onLoadFinished(Loader<Cursor> loader, Cursor c) {
    // TODO Auto-generated method stub
    
      adapter.swapCursor(c);
    
  }

  @Override
  public void onLoaderReset(Loader<Cursor> arg0) {
    // TODO Auto-generated method stub
    adapter.swapCursor(null);
  }
  
  
  static class MyCursorLoader extends CursorLoader {
        DB db;
      
      public MyCursorLoader(Context context, DB db) {
        super(context);
        this.db = db;
      }
      
      @Override
      public Cursor loadInBackground() {
                 //В начальный момент база данных пустая
           c = db.getData(orderStatus);
          
       return c;
      }
      
    }

Answer 1

lsof | grep deleted

Answer 2

ls -la /usr
du -cmh /usr

Answer 3

using the telepathic method:
#ls -l /var/spool/clientmqueue/
.... many many files that the senmail
solution generates (if the idea is guessed)
PS although of course /usr/... :( I'll

#du -cs /* | sort -n
...
1342636	/usr
12364008	/var
15006492	total
#du -cs /var/* | sort -n
...
1768308	/var/log
9570600	/var/lib
12364020	total
#du -cs /var/lib/* | sort -n

etc.
the line before total will be the most devouring directory, we will look at it next time ...

Answer 4

Adapter is empty because.
In the getData method, you get the Cursor and initialize the Loader. Since the Cursor is empty, the if branch fails and adapter is not initialized. The Loader then completes its loading with the onLoadFinished method, which calls adapter.swapCursor(c). adapter is null, so we get a crash.

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor c) {
    if (adapter != null) {
        adapter.swapCursor(c);
    }
}

@Override
public void onLoaderReset(Loader<Cursor> arg0) {
    if (adapter != null) {
        adapter.swapCursor(null);
    }
}

You also initialize adapter in a loop, which you don't have to do.
