內置Android共享模塊，Facebook Android應用程序

可以使用共享意圖共享到Facebook。當您點擊發送按鈕時，彈出對話框中會顯示設備上設置的默認應用程序列表。我的問題是，是否有可能只使用共享意圖共享一個應用程序。例如使用共享意圖只發送到Facebook。共享意圖直接打開本地Facebook應用程序。內置Android共享模塊，Facebook Android應用程序

我發現這個鏈接：http://vnstep.wordpress.com/2012/04/14/share-via-android/

但

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND); 
    shareIntent.setType("text/plain"); 
    shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "anc"); 
    shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "ccc"); 
    PackageManager pm = context.getPackageManager(); 
    List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0); 
    for (final ResolveInfo app : activityList) { 
     if ((app.activityInfo.name).contains("facebook")) { 
      final ActivityInfo activity = app.activityInfo; 
      final ComponentName name = new ComponentName(activity.applicationInfo.packageName, activity.name); 
      shareIntent.addCategory(Intent.CATEGORY_LAUNCHER); 
      shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED); 
      shareIntent.setComponent(name); 
      context.startActivity(shareIntent); 
      break; 
     } 
    }

得到錯誤日誌

不能過濾來自份額的意圖的任何應用程序。如果你仍然想這樣做，那麼使用Facebook SDK。
