重现步骤: 1.打开https://github.com/udacity/ud851-Exercises/tree/student/Lesson04a-Starting-New-Activities/T04a.01-Exercise-AddNewActivity作为android studio中的现有项目。
当添加新活动时,有时我会得到nullpointerexception并且没有任何视觉发生,有时我会得到一个创建新活动向导,在单击Finish按钮后,冻结并且我得到InvalidRefrenceException。
< / LI>我尝试过几次添加新活动,每次尝试后都得到nullPointerException。但是,在最后一次尝试时,向导出现了,但在点击完成按钮后,它冻结了,我得到了IllegalStateException。
此外,当我打开Android SDK管理器,SDK工具和其他标签时,sdk的所有版本以及底部的显示详细信息框都无法点击。
这是日志文本:

答案 0 :(得分:2)
这也发生在我身上,但仅限于从活动列表中创建活动时。如果您从图库创建新活动,则不会发生这种情况。 你在这里找到画廊:File-&gt; New-&gt; Activity-&gt; Galery
