這裏有gdk，sysimg，addons等的配置文件地址。

wget或者瀏覽器獲得xml，好比：

打開 https://dl-ssl.google.com/android/repository/sys-img/android/sys-img.xml

<sdk:system-image>

其中

<sdk:url>sysimg_armv7a-19_r02.zip</sdk:url>

就是sysimg arm -19的system image

而後下載地址就是xml地址去掉xml以後加上sysimg文件地址

也就是：https://dl-ssl.google.com/android/repository/sys-img/android/sysimg_armv7a-19_r02.zip

而後wget或者瀏覽器下載。

下載完解壓放在相應目錄

其中sdk放在sdkroot/platforms/下

sysimg放在sdkroot/system-images/android-xx下（xx表示版本好比上面的例子就是-19）

注意上面這些目錄能夠新建，而後容許android sdk manager看到installed狀態就說明成功手動安裝。
