Update android app from 4.2 to 9.0

Update existing android app build for Motorola XYBoard 10.1 (16:10 screen aspect ratio) Android OS 4.2 to support (2019) Samsung Galaxy Tab A 10.1 (16:10 screen aspect ratio), Android OS 9.0 or greater. Request the app source core refresh/ update to support the the latest android OS (9.0 or later) and latest google libraries / APIs (maps etc) for devices of same aspect ratio (2019 Samsung Galaxy Tab A 10.1 for example).

Expect the app to retain existing functionality on latest OS which include workflow, data entry, data save, GPS, camera, bar code scanning, export to PDF, etc.

Original source code (java) available. I would expect updated source code and .apk executable, test updated app on a 2019 Samsung galaxy tab 10.1 running android 9.0.
