title: Popup menu crash at show();
body: <p>So I'm trying to create a popup menu which will popup when user presses on ImageButton.</p>
  
  <p>I'm getting strange force close error on <code>popupMenu.show()</code>:</p>
  
  <pre><code>case R.id.action_menu_edit_biljeske_uredi:
    linearLayoutDodajBiljeskuBojeIOstalaSranja.setVisibility(View.VISIBLE);
    imageButtonBiljeskeDodajBiljeskuBojaPozadine
      = (ImageButton) findViewById(R.id.imageButtonBiljeskeDodajBiljeskuBojaPozadine);
    imageButtonBiljeskeDodajBiljeskuBojaPozadine.setOnClickListener(
      new View.OnClickListener() {
        @Override
        public void onClick(View v) {
          PopupMenu popupMenu = new PopupMenu(getApplicationContext(),
                                              imageButtonBiljeskeDodajBiljeskuBojaPozadine);
          popupMenu.getMenuInflater().inflate(R.menu.menu_popup_biljeske_boje,
                                              popupMenu.getMenu());
          popupMenu.show();
        }
      });
  }
  </code></pre>
