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.

Dear Sir/Madam, I am interested in updating your application natively for Android andwould like to hear more about what it involves. I would be happy to discuss the project further with you if you are interested and to answer any questions you may have about my experience, actually I have done a similar project recently on Freelancer with upgrading an existing app running on Android 2.3 to support Android 10. I am currently working as a freelance mobile developer in a digital nomad lifestyle, in the past I have worked for an Australian company and a German startup in full time positions developing mobile applications. I have over 6 years of industry experience and over a year of freelance experience as a native Android developer both with personal and contracted projects. I could give you some examples of my work and if necessary I can provide my CV for you. I look forward to hearing back from you soon.
