E/MicroMsg.SDK.WXMediaMessage:checkArgs fail,thumbData is invalid 图片资源太大导致分享失败

1、微信分享报：

2、这个问题是因为图片太大导致：

WXWebpageObject webpage = new WXWebpageObject();webpage.webpageUrl = qrCodeUrl;//用 WXWebpageObject 对象初始化一个 WXMediaMessage 对象WXMediaMessage msg = new WXMediaMessage(webpage);msg.title ="测试测试";msg.description ="这里是描述";Bitmap thumbBmp = BitmapFactory.decodeResource(getResources(), R.drawable.img);ByteArrayOutputStream baos = new ByteArrayOutputStream();thumbBmp.compress(Bitmap.CompressFormat.PNG, 90, baos);msg.thumbData = baos.toByteArray();//构造一个ReqSendMessageToWX.Req req = new SendMessageToWX.Req();req.transaction = buildTransaction("webpage");req.message = msg;req.scene = WXSceneSession;//调用api接口，发送数据到微信api.sendReq(req);

说明：R.drawable.img 这个资源文件不能太大，大了就会报错，一般控制在32Kb.
