Android Studio 2.2 不显示任何带有 java.lang.NullPointerException 的项目

Question

我在 android studio 中遇到了新问题。我看不到我的任何项目。我只能看到一个空白屏幕。

我得到了这样的错误。

java.lang.NullPointerException

现在我无法打开我的所有项目并且在完成我的任务时遇到麻烦。 有什么帮助吗？

终于可以解决问题了。我正在使用 Windows 操作系统。我打开任务管理器并关闭 Android Studio 程序。重新打开 Android Studio 后，我恢复了之前设置的所有首选项，所有项目都链接起来了。

@Martin Revert Solution 可以关注。但请记住，所有项目首选项都将被删除，您可能必须设置 SDK 路径和所有必要的东西。否则你可以按照我的解决方案。
