Java 网页不可用，WebView Android

你好，我有个问题，我有一个家庭作业要用android studio制作网页视图，我输入url facebook，然后运行它，但就是这样

我对我的清单有权限，但在我的avd网页中仍然不可用

日志：

WebView WebDimrah;
WebSettings WebSettingDimrah;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    WebDimrah  = (WebView)findViewById(R.id.WebView1);
    WebSettingDimrah  = WebDimrah.getSettings() ;

    WebDimrah.setWebViewClient(new WebViewClient());
    WebDimrah.getSettings().setJavaScriptEnabled(true);
    WebDimrah.loadUrl("https://facebook.com");
