獲取錯誤張貼到Facebook牆

我已經搜索谷歌和stackoverflow，但我找不到解決方案。我試圖將facebook整合到我的應用程序中，以便用戶可以直接向我的Facebook粉絲頁面推薦新的啤酒品牌。因爲現在我每天收到3封電子郵件，讓用戶推薦新的啤酒品牌。獲取錯誤張貼到Facebook牆

我做了什麼： - 創建了一個Facebook開發者帳戶，啓用了Native Android應用程序並插入了Key-Hash等。 - 下載並集成了facebook sdk。 - addet上網權限 - 集成了Facebook的以下輔助類：

package com.celticwolf.nsod; //changed 
import com.facebook.android.*; 
import com.facebook.android.Facebook.DialogListener; 
import android.app.Activity; 
import android.content.Context; 
import android.content.SharedPreferences; 
import android.content.SharedPreferences.Editor; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.view.Window; 
import android.widget.Toast; 

public class ShareOnFacebook extends Activity{ 
    private static final String APP_ID = "35253892647899"; // changed 
    private static final String[] PERMISSIONS = new String[] {"publish_stream"}; 
private static final String TOKEN = "access_token"; 
     private static final String EXPIRES = "expires_in"; 
     private static final String KEY = "facebook-credentials"; 

    private Facebook facebook; 
    private String messageToPost; 

    public boolean saveCredentials(Facebook facebook) { 
      Editor editor = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE).edit(); 
      editor.putString(TOKEN, facebook.getAccessToken()); 
      editor.putLong(EXPIRES, facebook.getAccessExpires()); 
      return editor.commit(); 
     } 

     public boolean restoreCredentials(Facebook facebook) { 
      SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE); 
      facebook.setAccessToken(sharedPreferences.getString(TOKEN, null)); 
      facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0)); 
      return facebook.isSessionValid(); 
     } 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     facebook = new Facebook(APP_ID); 
     restoreCredentials(facebook); 

     requestWindowFeature(Window.FEATURE_NO_TITLE); 

     setContentView(R.layout.facebook_dialog); 

     String facebookMessage = getIntent().getStringExtra("facebookMessage"); 
     if (facebookMessage == null){ 
      facebookMessage = "Test wall post"; 
     } 
     messageToPost = facebookMessage; 
    } 

    public void doNotShare(View button){ 
     finish(); 
    } 
    public void share(View button){ 
     if (! facebook.isSessionValid()) { 
      loginAndPostToWall(); 
     } 
     else { 
      postToWall(messageToPost); 
     } 
    } 

    public void loginAndPostToWall(){ 
     facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH, new LoginDialogListener()); 
    } 

    public void postToWall(String message){ 
     Bundle parameters = new Bundle(); 
       parameters.putString("message", message); 
       parameters.putString("description", "topic share"); 
       try { 
        facebook.request("me"); // <------ here it fails 
      String response = facebook.request("me/feed", parameters, "POST"); 
      Log.d("Tests", "got response: " + response); 
      if (response == null || response.equals("") || 
        response.equals("false")) { 
       showToast("Blank response."); 
      } 
      else { 
       showToast("Message posted to your facebook wall!"); 
      } 
      finish(); 
     } catch (Exception e) { 
      showToast("Failed to post to wall!"); 
      e.printStackTrace(); 
      finish(); 
     } 
    } 

    class LoginDialogListener implements DialogListener { 
     public void onComplete(Bundle values) { 
      saveCredentials(facebook); 
      if (messageToPost != null){ 
      postToWall(messageToPost); 
     } 
     } 
     public void onFacebookError(FacebookError error) { 
      showToast("Authentication with Facebook failed!"); 
      finish(); 
     } 
     public void onError(DialogError error) { 
      showToast("Authentication with Facebook failed!"); 
      finish(); 
     } 
     public void onCancel() { 
      showToast("Authentication with Facebook cancelled!"); 
      finish(); 
     } 
    } 

    private void showToast(String message){ 
     Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show(); 
    } 
}

，我已經addet下面的代碼來訪問輔助類：

private void shareonfb(){ 
     Intent postOnFacebookWallIntent = new Intent(this, ShareOnFacebook.class); 
     postOnFacebookWallIntent.putExtra("facebookMessage", "Teeeeeeeeeeeest"); 
     startActivity(postOnFacebookWallIntent); 
    }

凡失敗： - 我能夠登錄到Facebook，但當它詢問我是否想分享它時，在以下代碼塊中失敗：

public void postToWall(String message){ 
    Bundle parameters = new Bundle(); 
      parameters.putString("message", message); 
      parameters.putString("description", "topic share"); 
      try { 
       facebook.request("me"); // <------------- here it fails and jups to catch 
     String response = facebook.request("me/feed", parameters, "POST"); 
     Log.d("Tests", "got response: " + response); 
     if (response == null || response.equals("") || 
       response.equals("false")) { 
      showToast("Blank response."); 
     } 
     else { 
      showToast("Message posted to your facebook wall!"); 
     } 
     finish(); 
    } catch (Exception e) { 
     showToast("Failed to post to wall!"); 
     e.printStackTrace(); 
     finish(); 
    } 
}

這裏是日誌:(我標記了它失敗的部分）

從android 3.0 AFAIK開始，你不能在主線程中進行網絡操作。發出呼叫的sperate線程，如果你需要更新UI兼用handlers或AsyncTask

例如：

class MyAsyncTask extends AsyncTask<String,Void,Boolean> 
{ 
public Boolean doInBackground(String ...message){ 

    Bundle parameters = new Bundle(); 
      parameters.putString("message", message[0]); 
      parameters.putString("description", "topic share"); 
      try { 
       facebook.request("me"); // <------------- here it fails and jups to catch 
     String response = facebook.request("me/feed", parameters, "POST"); 
     Log.d("Tests", "got response: " + response); 
     if (response == null || response.equals("") || 
       response.equals("false")) { 
      return Boolean.FALSE; 
     } 
     else { 
      return Boolean.TRUE; 
     } 
    } catch (Exception e) { 

     e.printStackTrace(); 
     return Boolean.FALSE; 
    } 
} 

public void onPostExecute(Boolean result){ 
     if(result == Boolean.TRUE){ 
showToast("posted successfully"); 
}else{ 
showToast("couldn't post to FB."); 
} 
     finish(); 
} 
}

看到這個NetworkOnMainThreadException

謝謝！有效！！如果有人想知道。我用Nammaris解決方案替換了失敗的代碼塊，並通過以下方式調用它：new MyAsyncTask（）。execute（message）;還有一個問題。你知道如何發佈在Facebook Fanpage上嗎？ – LxSwiss
