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.
** Is an urgent job, must be solved as fast as u can. Thanks.
