           try{
               int klok = 0;
               while(klok < 5000){
                   sleep(100);
                   klok = klok + 100;
               }

                try{



                   String[] items = new String[] {"One", "Two", "Three"};
                  ArrayAdapter<String> adapter = new ArrayAdapter<String>(Materiaal.this, android.R.layout.simple_spinner_item, items);
                  adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
                  spinner1.setAdapter(adapter);



                    }catch(Exception ex){
                       ex.printStackTrace();
                    }finally{
                        //adapter.notifyDataSetChanged();

                    }

           }catch(InterruptedException ex){
               ex.printStackTrace();
           }

       }
    };

    asyn.start();

I think you should use the method runOnUiThread(Runnable r) from the Activity.

Maybe do something like this

void run()
{
    // do stuff
    .
    .
    .
     activity.runOnUiThread(new Runnable()

         void run()
         {
             spinner1.setAdapter(adapter);
         }

     );
}

I hope it helps..
