Android Studio安装SDK失败解决办法 

安装SDK时界面会显示安装的连接，同时在你选择的安装SDK的文件夹里面会生成一些目录和文件，在你选择放SDK的目录下有一个叫做.temp的文件夹，里面放的就是下载的临时文件。

.temp内部的文件夹里面能看到下载的具体文件名，我们可以直接复制在下载信息框的链接，粘贴到浏览器或者下载器里面下载，下载完了之后把下载的文件放到.temp文件夹内部的对应文件夹内。放好自己下载的文件后，把自动生成的那个带文件名的文件删掉，简单来说就是用自己下载好的去替换临时下载文件，这样就会被识别为下载完成并会自动解压安装。

我是实测成功了才截图的，所以,temp文件夹内没有任何文件夹了，因为都下载安装完成了。

粘一下安装SDK所有输出信息
