原先集成過微信的分享，分享到朋友圈和微信對(duì)話都沒有問題。

項(xiàng)目上線由于圖片各異，最近會(huì)偶爾出現(xiàn)分享到朋友圈時(shí)候根本就打不開share的界面，但是到微信聊天是可以；

下面貼出先前的代碼：

Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.send_img);

WXImageObject imgObj = new WXImageObject(bmp);

WXMediaMessage msg = new WXMediaMessage();

msg.mediaObject = imgObj;

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 = isTimelineCb.isChecked() ? SendMessageToWX.Req.WXSceneTimeline : SendMessageToWX.Req.WXSceneSession;

api.sendReq(req);

很多人說是縮略圖的大小的問題，但是在將縮略圖改成很小之后還是沒有成效。最后換成下面微信sdk提供的一種方式：

WXImageObjectimgObj=newWXImageObject();

imgObj.setImagePath(mCurrentUrl);

WXMediaMessage msg=newWXMediaMessage();

msg.mediaObject=imgObj;

Bitmap bmp=BitmapFactory.decodeFile(mCurrentUrl);

Bitmap thumbBmp=Bitmap.createScaledBitmap(bmp,THUMB_SIZE,THUMB_SIZE,true);

//? ?? ?? ?? ?? ? bmp.recycle();

msg.thumbData=bmpToByteArray(thumbBmp,true);// 設(shè)置縮略圖

SendMessageToWX.Req req=newSendMessageToWX.Req();

req.transaction=buildTransaction("img");

req.message=msg;

req.scene= isTimelineCb ?SendMessageToWX.Req.WXSceneTimeline:SendMessageToWX.Req.WXSceneSession;

booleanflag=mWXAPIFactory.sendReq(req);
