Android Studio断点调试的时候提醒Warning: No executable code found at line

在Studio的断点调试的时候，增加断点后，总是提醒无可执行代码，可明明该语句会被执行的，于是乎就搜索了一下，最后结果如下，应该是Studio的问题：

I had similar problems and various attempts has been applied. Below is my usual steps:

1. If you are using Maven dependencies, go to Maven Projects -> refresh
2. If that does not work, Try top menu --> Build --> Rebuild Project
3. If that still doesn't work, try top menu --> File --> Invalidate Cache/Restart
4. If that still doesn't work, then $CATALINA_BASE/bin/catalina.sh stop, then start

After this, usually it covers 99% of the problems. Otherwise, Probably you will have to examine some other possibilities.
