, you can see what’s going on, what’s going on in which path, which class, what’s going on and my problem is I can’t find this package, and I can just fix it and I’m sure as long as I get to the problem, it’s not that hard for the programmer monkey to fix it, right?

However, my AndroidStudio did not set the automatic deletion of useless packages, so this problem occurred when I was packing. Here, I would also like to show the Settings of AndroidStudio’s automatic guide package and automatic delete package
