Downgrade android app to make work to 5.1.1 and not crush

Now the problem is this app, that u login read QR and answer some questions, works in android 7, and 6, but in android 5.1.1 when u log, and try to syncs in the API, in version 5.1.1 crush, and also stops working the QRs readers, and only appears camera, and it not works.

- U should downgrade to make work.

- Logs without crush, so needs to sync as other versions.

- Make work the Camera as QRs readers.

* Video atached, to check principal error, i clear the cache to show login.

Please share your logcat while the app crashes along with the app code. I would suggest you integrate Crashlytics so it will be easy to track crashes.
