微信android sdk 能否一次发送多张图片？

WXImageObject imgObj = new WXImageObject();
imgObj.setImagePath(path);

WXMediaMessage msg = new WXMediaMessage();
msg.mediaObject = imgObj;

Bitmap bmp = BitmapFactory.decodeFile(path);
Bitmap thumbBmp = Bitmap.createScaledBitmap(bmp, THUMB_SIZE, THUMB_SIZE, true);
bmp.recycle();
msg.thumbData = Util.bmpToByteArray(thumbBmp, true);

SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = buildTransaction("img");
req.message = msg;
req.scene = SendMessageToWX.Req.WXSceneTimeline ;
api.sendReq(req);


以上代码可以分享一张图片到微信朋友圈，但是如果 想要一次分享多张图片怎么办啊
