Nullpointer新活动向导

标签: android android-studio nullpointerexception wizard

我正在通过Udacity学习Android。我正在进行Intents课程,“练习:创建一个活动”,其中一个课程是使用Android Studio向导创建一个新的Activity。

会发生什么:我转到新的>活动>清空Activty,然后出现丑陋的Null指针。

“插件Android支持中的异常。片刻之前。自上次清除后发生了5次。未读。禁用插件”。

我已经尝试过:

  • 更改buildToolsVersion
  • 安装Android Studio 2.3 Beta(我使用的是最新的稳定版本:2.2)
  • 使缓存无效/重新启动
  • 导入其他项目
  • 检查了我的JAVA_HOME(1.8.0_92-b14)
  • 向Google报告此问题
  • 禁用插件(当我这样做时,显示了很多错误,所以我回滚了更改)

这些都没有解决我的问题。任何人都可以帮助我吗?
