安卓分享9宫格图片到微信

首先感谢@DCloud_Android_磊子，test_weixin_share_mul_pic这个是他写给我的，我只做了一点小改动
用法，先setShareMsg把当前页面的商品名称、相册存到全局变量msg，然后调用shareToWechat弹出actionSheet选择分享到朋友圈或者发送给好友。
函数代码如下：

  function setShareMsg(goodsdata){  
            msg.content = msg.title = goodsdata.goods_name;  
            /* 分享图片 */  
            mui.each(goodsdata.pictures, function(i, n){  
                msg.pictures.push( n.url );  
            });  
            /* 分享链接 */  
            msg.href = mui.constMap.SERVER_HOST + "/mobile/goods.php?id=" + goodsdata.id ;  
            msg.thumbs.push("_www/72.png");  
            var userdata = getCachedUser();  
            if(userdata ){  
                msg.href += "&father=" + userdata.user.wx.wxid;  
            }  
            msg.brief = goodsdata.goods_brief;  
            getShortUrl(msg.href, function(result){  
                if(! result.error_code){  
                    msg.url_short = result[0].url_short;  
                }  
            });  
        }  
                  /**  
         * 发送分享消息  
         * @param {plus.share.ShareService} s  
         */  
        function shareMessage(ex) {  
            var pictures = [];  
            var pic_unloaded = msg.pictures.length ;  
            function onStateChanged( d, status ) {  
                switch(d.state){  
                    case 4:  
                        if(status == 200){  
                            console.log("图片下载完成：" + d.filename);  
                            pictures.push( plus.io.convertLocalFileSystemURL(d.filename) );  
                            pic_unloaded --;  
                            if(pic_unloaded == 0){  
                                copyToClip( msg.title + (msg.url_short || msg.href) + "\r\n" + msg.brief );  
                                mui.toast("标题已复制，请长按黏贴");  
                                console.log(JSON.stringify(pictures));  
                                test_weixin_share_mul_pic(ex, pictures, msg.title + (msg.url_short || msg.href) + "\r\n" + msg.brief);  
                            }  
                        } else {  
                            mui.toast("下载图片失败");  
                        }  
                        break;  
                    case 1:  
                        console.log("下载开始");  
                        break;
