如何發送請求所有Facebook的朋友在facebook 3.0 android

我必須發送應用程序請求給所有朋友在這裏我使用此代碼發送請求只有一個朋友它工作正常，但我想發送請求多個/所有朋友如何發送請求所有Facebook的朋友在facebook 3.0 android

private void sendRequestDialog() { 
    Bundle params = new Bundle(); 
    params.putString("to", "1782990807"); 
    params.putString("message", 
      "Learn how to make your Android apps social"); 

    WebDialog requestsDialog = (new WebDialog.RequestsDialogBuilder(
      Logout.this, Session.getActiveSession(), params)) 
      .setOnCompleteListener(new OnCompleteListener() { 
       @Override 
       public void onComplete(Bundle values, 
         FacebookException error) { 
        if (error != null) { 
         if (error instanceof FacebookOperationCanceledException) { 
          Toast.makeText(
            Logout.this.getApplicationContext(), 
            "Request cancelled", Toast.LENGTH_SHORT) 
            .show(); 
         } else { 
          Toast.makeText(
            Logout.this.getApplicationContext(), 
            "Network Error", Toast.LENGTH_SHORT) 
            .show(); 
         } 
        } else { 
         final String requestId = values 
           .getString("request"); 
         if (requestId != null) { 
          Toast.makeText(
            Logout.this.getApplicationContext(), 
            "Request sent", Toast.LENGTH_SHORT) 
            .show(); 
         } else { 
          Toast.makeText(
            Logout.this.getApplicationContext(), 
            "Request cancelled", Toast.LENGTH_SHORT) 
            .show(); 
         } 
        } 
       } 
      }).build(); 
    requestsDialog.show(); 
}
