Android Studio IDE exception can't open Layout Resources xml files

Question

Android studio is throwing an null pointer exception related to the Android Support plugin when opening. As a result I can't open layout resources xml files.

I've tried

Invalidating Caches/ and restart
Cleaning/rebuilding project
Disabling Android SDK support plugin

Any help would be appreciated.Stack trace is below.

java.lang.StringIndexOutOfBoundsException: String index out of range: 0 at java.lang.String.charAt(String.java:658) at com.android.ide.common.resources.FileResourceNameValidator.getErrorTextForNameWithoutExtension(FileResourceNameValidator.java:135) at com.android.ide.common.resources.FileResourceNameValidator.getErrorTextForFileResource(FileResourceNameValidator.java:117) at com.android.ide.common.resources.FileResourceNameValidator.validate(FileResourceNameValidator.java:48) ...

No everything is there as normal. I just can't open any of the layout files. They are still on the disk and can be opened in the explorer, just not in android studio when I click them. — Esteban Rodriguez, Jan 31 '19 at 01:26
Solved! Somehow I accidentally deleted one of the layout files filename. It was just .xml. No name! I was able to revert the change and afterwards I could open all the layout resource files. — Esteban Rodriguez, Jan 31 '19 at 02:26

Based on your answer, I think you should make sure you have every files in your project directories. Try to debug buy going to Analyze --> Inspect Code

and let it run for a while. Any errors will be marked as red. Check it if one of the files have missing references like your case above. More can be found here,
