Android Studio 安装完成后，如果直接启动，Android Studio会去获取 android SDK组件信息，这个过程相当慢，还经常加载失败，导致Android Studio启动不起开。错误信息：
Android SDK was installed to E:developmentandroidsdks

解决办法就是不去获取androidSDK组件信息。方法如下：
1）进入刚安装的Android Studio目录下的bin目录。找到idea.properties文件，用文本编辑器打开。
2）在idea.properties文件末尾添加一行： disable.android.first.run=true ，然后保存文件。
3）关闭Android Studio后重新启动，便可进入界面。
