Java 无法从Android授权LinkedIn应用程序

我正在尝试授权LinkedIn应用程序将状态从我的Android应用程序发布到LinkedIn。但当我点击授权时，我的网络视图中没有显示任何内容

这是我自己的AuthLinkPage.java：

public class OwnOuthLinkPage extends Activity  implements SoapClient {
    /** Called when the activity is first created. */
    Button  b;
    WebView wb;
    String ftoken,verifire,outh_token,verifire2,requesttokensecret,urlM,OuthT;
