Answer 1

I ran into this very issue today morning and found the solution for it too. This issue is created when you have messed up one of your .xml files. I'll suggest you to go through them one by one and look for recent changes made. It might be caused a silly mistake.

In my case, I accidentally hardcoded a color string as #FFFFF (Bad practice, I know. I was just trying out variations). As you can see it had 5 F instead on 6. It didn't show any warning but was root of the same issue as encountered by you

Answer 2

Add the following code to the file "gradle.properties" in your project.

    android.enableAapt2=false
