// 错误处理
xhr.onerror = function (arg0) {
cc.error("下载gif错误：", arg0)
}
try {
xhr.open("GET", url, true);
} catch (error) {
console.log("xhropen失败！！！")
console.log(error)

console.log("gif：send..." + url)
xhr.send();
基本上就是这样了，在Andrdoid上运行，不进onload，也不调onreadystatechange（仅在开始的时候调用一次，状态为0-开始，后面就再也没有反应了）
希望大家贡献一些思路，解决这个问题。
