出现这个问题以后，我百度了一番，网上提供的解决办法是这样的：

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。

我照做了以后，发现问题照旧，百思不得其解。

无意中怀疑是编码问题，保存idea.properties文件文件时将编码设置为utf-8, 终于启动成功。

经过测试，选择ANSI和utf-8无问题，选择Unicode格式则出现问题。

我去  怎么没有人回呢?
