Please provide the following:

Platforms(Android/iOS/web/all): android (all?)
Hi all, I’m working on a React Native mobile app where neither the primary developer nor I can get a new build to behave. I’ve spent hours rebuilding this in various ways to ensure AWS build is behaving properly… and it seems to be.
Doing the following basic steps…
git clone
amplify init
npm install
expo start
… followed by pulling up the app an android device (tunnel or lan), yields our expected login screen. Once we log in, however, we get the null object reference error with no discernible information in the console, or stack that we can figure out what is resulting in this error.
Any suggestions? Help would be greatly appreciated.

## Description
I've built a music player app and when user taps on the next or previous buttons, a state change happens.
I get this error when user taps on these buttons rapidly.
![screenshot-2019-01-23_17 23 57 731](https://user-images.githubusercontent.com/30038691/51611277-1d30ab00-1f34-11e9-9eed-498f86891d96.png)
this error causes the app to crash in production releases. but I've received these reports only on **android** devices. no reports for iOS devices. I don't know if that's relevant.
## Reproducible Demo
I can't share my code because of NDA stuff.
