preface

First of all, there is no problem with the operation of the program and every step of the application is not affected. However, When loading the XML layout, AndroidStudio always prompts that the XML file has not been changed. However, I have clearly created the XML file because I directly click to create it, which is impossible I intentionally created the XML layout by hand again, but when I clicked ok, I was told that the XML file already existed!

Problem description

So someone asked me about a project that relies on dozens of third-party libraries and HOW do I know which one is the problem?

May I ask what your original problem was?

This reminds me of a line from a movie I’ve seen

It’s a movie starring Guo Da Statham. If you’re interested, you can watch it. It’s fun!
