I'm desperate. Let's see if someone does not give up and can help me solve it
I think I've already seen more than 10 pages on how to fix the R error in android. but none of the solutions is worth me.
My project worked fine and suddenly all references to R fail. in all the files. It happened to me once and to update android appeared to me, I copied all the code of the project and I created a new project, I pasted the code and it seems that in that new one that worked well. This time he has appeared by good.
I have already done the Clean Project, Rebuild Project, rebooted Android Studio and nothing, still appears. I'm desperate and helpless with this mistake. For those of us who are just starting, it's a desperation.
How do I solve it?
Photos of errors: (appear in absolutely all files with references to R
