I am getting a NPE in the 1.3.15 version also. The issue looks similar. This happened to me when re-running an app after it had been left sitting for 20 minutes:

In my case I pulled the tooltip into my project as a library and edited it. I also added ability to resize the text.

What was actually causing the NPE? I get this when closing or destroying a fragment while the tooltip is still showing. I implemented RxLifecycle and even bound it to the fragment's lifecycle but it still keeps crashing
