Error says:

Caused by: java.lang.NullPointerException: Attempt to read from null array
at com.tomer.fadingtextview.FadingTextView.startAnimation(FadingTextView.java:289)

This error is relative to the older version of the library which was the message pointed FadingTextView.java:289.

This might be starting animation before checking the length of the texts.

version 3.1 fixes the error in FadingTextView.kt:218 (#22)

@rockakassh Can you check that the latest version fixes the problem?
