Android Studio v1.2.0 启动错误: java. lang.NullPointerException

Question

将 Android Studio 更新到 v1.2.0 后。 启动时出现以下日志并且无法打开 Android Studio。我使用的是 Windows 7-64bit，在 Ubuntu 中也出现同样的错误

Android Issues 中也报告了此问题，但仍然没有解决办法

Answer 1

Issue #170849给出了上述崩溃的原因。

1. This happens (at least) when no sdk is installed and no remote repos that contain platforms are available.
2. Actually it happens whenever remote sites aren't available and the first run wizard is run.

从 Issue #170850 找到一个临时解决方案 :

将以下代码添加到 C:\Program Files\Android\Android Studio\bin\idea.properties

disable.android.first.run=true

更新

该问题已在 Issue #170849 下得到修复.
