AndroidStudio debug mode debugging cannot enter the breakpoint in the callback method

Today, I found that I couldn't enter the breakpoint of the callback when I checked the return result of the network request debug running program. Later, after testing, I found that the request returned the result normally. Later, I found a similar question in Baidu's "Android Bar". Some people answered that it was because of a problem with the stable version of AndroidStudio4.1. This problem has been fixed in the latest "AndroidStudio Development Edition". The stable version can only wait and see.
