嗨，我需要從我的應用程序的Facebook共享文本我嘗試了通過安裝Facebook的，但與空白後打開Facebook發佈這個代碼分享文本從Android應用

Intent sharingIntent = new Intent(Intent.ACTION_SEND); 
     sharingIntent.setType("text/plain"); 
     sharingIntent.putExtra(Intent.EXTRA_SUBJECT, DESCRIPTION); 
     sharingIntent.putExtra(Intent.EXTRA_TEXT, DESCRIPTION); 
     PackageManager packManager = getPackageManager(); 
     List<ResolveInfo> resolvedInfoList = packManager.queryIntentActivities(sharingIntent,  PackageManager.MATCH_DEFAULT_ONLY); 

     boolean resolved = false; 
     for(ResolveInfo resolveInfo: resolvedInfoList){ 
      if(resolveInfo.activityInfo.packageName.startsWith("com.facebook.katana")){ 
       sharingIntent.setClassName(
        resolveInfo.activityInfo.packageName, 
        resolveInfo.activityInfo.name); 
       resolved = true; 
       break; 
      } 
     } 
     if(resolved){ 
      startActivity(sharingIntent); 
     }else{ 

      android.app.AlertDialog.Builder alert = new AlertDialog.Builder(SingleItemView.this); 
       alert.setTitle("Warning"); 
       alert.setMessage("Facebook App not found"); 
       alert.setPositiveButton("OK", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog,int which) 
        { 
         dialog.dismiss();
