和属性面板在加载时卡住，

and Properties panel stuck on loading,

我的操作系统是 ubuntu 16.04，几乎我已经将 Android SDK 中的所有内容都升级到了最新版本.

My OS is ubuntu 16.04 and almost i have upgraded everything in Android SDK to the latest version.

推荐答案

最后我通过将 compileSdkVersion 和 targetSdkVersion 从 24 更改为 23 解决了这个问题.实际上这不是解决异常的正确方法，但我不能此刻找到任何解决方案.

Finally i solved the issue by changing the compileSdkVersion and targetSdkVersion from 24 to 23. Actually it is not a proper way to resolve the exception, but i couldn't find any solution at this moment.
