android getting null pointer exception at java.util.Objects.requireNonNull(Objects.java:203)

I'm reading writing string arrays and displaying them in recycler view. Before displaying them i'm reversing the order using Collections.reverse(Arrays.asList(FilePathStrings)); Following is exception that I'm getting:
