Проблемы с WebView

Организую экраны с помощью Flipper

    LinearLayout mainLayout = (LinearLayout) findViewById(R.id.main_layout);
    mainLayout.setOnTouchListener(this);
    flipper = (ViewFlipper) findViewById(R.id.flipper);
    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    int layouts[] = new int[]{R.layout.scr1, R.layout.scr2, R.layout.scr3, R.layout.scr4};
    for (int layout : layouts) flipper.addView(inflater.inflate(layout, null));

В onCreate прописываю

 wv_scr4 = (WebView) findViewById(R.id.wv_scr4)

Пытаюсь загрузить страницу

   Log.d(Vrbl.LOG_TAG,"RisScr4");
   wv_scr4.loadUrl("file:///android_asset/faktor.html");

Но как только исполнение доходит до этой строки, программа вылетает.

Если перед этим разместить любые действия связанные с вызовом wv_scr4, программа сразу вылетает.

Например

 wv_scr4.getSettings().setJavaScriptEnabled(true);

или

 wv_scr4.getSettings().setSupportZoom(true);

Все другие экраны содержат TextView и все хорошо, если убираю wv_scr4 В чем может быть проблема?
