I need a developer to make an android application, I have a bunch of spare android tablets Samsung SM-T378V, which run android 7.1.1 and would like to repurpose them.

the application is very simple, it needs to read the serial stream of a Bluetooth device(HC-05) sending data from RS232 Serial, parse the data (space separators), and plot two variables on the screen, half of the screen with one variable, enlarged as much as possible, the lower half with the second variable. black background, one variable in green, the other in red, desired variables are labeled on the document as Depth (green variable) on TOP and Tension (red variable) on Bottom

Attached is some text captured from the serial stream for reference and the data format from the serial device

All the code for the project is needed, I will upload to the device using Android Studio latest version

Note:

The space separator is a little tricky, I am attaching a parser in C as an example, used in a PLC, need to be careful on the position of the variables, since the second value can be a character or a space, and therefore be considered by the parser as a position on the table, suggestions accepted

A couple of days is expected for the completion of this project.

Extra:

The application should run on Kiosk, and block button functionality to prevent exiting the app
