的Android的Facebook-SDK崩溃

这是代码

private void share() { 
    facebookClient = new Facebook(APP_API_ID); 
    facebookClient.authorize(this, 
      new String[] {"publish_stream", "read_stream", "offline_access"}, this); 
} 

@Override 
public void onComplete(Bundle values) { 

    if (!values.containsKey("post_id")) 
    { 

    try { 
      String response = facebookClient.request("me"); 
      Bundle parameters = new Bundle(); 
      parameters.putString("name","Name"); 
      parameters.putString("description", "Description"); 
      parameters.putString("link", "Link"); 
      parameters.putString("picture","Picture"); 
      response = facebookClient.request("me/feed", parameters, "POST"); 
      Log.d("Tests", "got response: " + response); 
      if (response == null || response.equals("") || response.equals("false")) { 
       Log.v("Error", "Blank response"); 
      } 

    } catch(Exception e) { 
     e.printStackTrace(); 
    } 
    } 
}

这是崩溃日志

邮政完整的堆栈跟踪更换

String response = facebookClient.request("me");

。另外 - NullPointerExceptions是最容易找到的。所有你需要做的就是调试，并且步入NPE发生的地步，然后评估你的变量。 – Jack

请参阅http://stackoverflow.com/questions/6525005/npe-at-android-webkit-webview-onwindowfocuschanged – larham1

试试与

String response = "";

它没有帮助我 – user998955

你知道哪一行返回nullpointerException吗？你可以在每行调试和中断，直到应用程序崩溃。 –

此代码适用于Galaxy，但不适用于G1 – user998955
