My activity is boliches:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_boliches);
        WebView view = (WebView) this.findViewById(R.id.Visorboliches);
        view.setWebViewClient(new WebViewClient());
        String url = "asdasd645546546";
        view.loadUrl(url);
        view.getSettings().setJavaScriptEnabled(true);


    }

Check that you actually have a WebView with id Visorboliches within the layout activity_boliches.xml , if it does not exist, the instance of the WebView (view) has a null value:

  WebView view = (WebView) this.findViewById(R.id.Visorboliches);
  view.setWebViewClient(new WebViewClient());
