Java Tabhost，android.view.WindowManager$BadTokenException:无法添加窗口

你好，在我的应用程序中，我正在使用TabHost

现在，我正在webview中打开twitter选项卡、facebook选项卡页面，它已成功加载，但在登录时，如果我在传递用户名和密码后按下登录按钮，应用程序将崩溃，并出现以下错误

我加载facebook页面或twitter页面的类是

    public class FacebookActivity extends Activity implements OnClickListener {

private WebView mWebView;
ProgressDialog PD;
String sabNZBurl;

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

    sabNZBurl = getResources().getString(R.string.fburl);

    mWebView = (WebView) findViewById(R.id.webView1);
    // Added by Pankit -------- start
    if (!TabSample.checkForInternet.isNetworkAvailable(this, this)) {
        Toast.makeText(TabSample.tabContext,
                "No Net Connection... Exiting...", 2000).show();
        exitOnNoNetConnection();

    } else {

        // Added by Pankit -------- End
        PD = new ProgressDialog(TabSample.tabContext);
        PD.setMessage("Please Wait......");
        PD.show();
        mWebView.getSettings().setJavaScriptEnabled(true);
        mWebView.getSettings().setDomStorageEnabled(true);
        mWebView.setWebViewClient(new MyWebViewClient());
        mWebView.loadUrl(sabNZBurl);
     }
}

   final class MyWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }

    @Override
    public void onLoadResource(WebView view, String url) {
        super.onLoadResource(view, url);

    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        PD.dismiss();
    }
}
