Nocturnal simulator settings agent cannot be saved

Recently, I encountered a problem that stuck me for a long time , Finally, I was really stupid by myself , Baidu has found no relevant solutions for a long time , Write a blog to share , Maybe there are some careless friends like me , I hope you don't stay here too long

The problem is ： After setting the proxy for Android simulator ,“ preservation ” Key cannot be selected , Pictured ：

The reason for the mistake is , No proxy server port number entered ！！！

On the picture 8080 Is a clue word （placeholder）, Not the default value entered , You also need to input by yourself .

Visually, losing is the same as not losing , Be careful ！！
